DOI: 10.3897/ijm.7.3064

Authors: Monica Farfan, Hans Klompen

Abstract: Introduced millipede species in the family Julidae are common in the U.S. but little is known about how they interact with other organisms, such as mites. To start to determine the nature of the relationship, millipedes were sampled from across the eastern U.S.A. and the United Kingdom in 2008–2009. Sixteen morphospecies of mites (Acari: Astigmata, Mesostigmata) were collected from these millipedes, 12 of which from a total of 13 species of julid millipedes. None of these 12 species was restricted to a single host species. However, 12 of the 16 mite species collected were restricted to either the U.S.A. or the U.K. These results are consistent with locality, rather than host, specificity.

The centipedes (Chilopoda) of Corsica: catalogue of species with faunistic, zoogeographical and ecological remarks https://ijm.pensoft.net/article/1920/ International Journal of Myriapodology 7: 15-68

DOI: 10.3897/ijm.7.3110

Authors: Marzio Zapparoli, Etienne Iorio

Abstract: Published and unpublished data on the centipedes of Corsica (France) is summarised and critically reviewed in this paper. Thirty-three species are listed and discussed (1 Scutigeromorpha, 11 Lithobiomorpha, 4 Scolopendromorpha, 17 Geophilomorpha), one of which is new to the island: Henia (Pseudochaetechelyne) brevis (Silvestri, 1896). General geographical distribution, chorotype, exact localities and ecological notes (altitudinal range, habitats) are given for each species. Eight species are Corsican endemics. Taxonomic remarks are given for some species. General notes on the composition of the centipede fauna of Corsica and its zoogeographic affinities as well as remarks on the ecology of the species and their assemblages are also included.

Seasonal patterns of activity of Scolopendra cretica and S. cingulata (Chilopoda, Scolopendromorpha) in East Mediterranean maquis ecosystem https://ijm.pensoft.net/article/1921/ International Journal of Myriapodology 7: 1-14

DOI: 10.3897/ijm.7.2133

Authors: Dimitris Kaltsas, Stylianos Simaiakis

Abstract: The seasonal activity patterns of Scolopendra cingulata and S. cretica in relation to abiotic factors and microhabitat preferences in five eastern Mediterranean maquis formations were studied. The abundance of both species proved to be spatially non-variant, suggesting a uniform distribution of populations, which exhibited a statistically similar phenological pattern, peaking in early-midsummer. The variability of the temporal activity patterns in Crete, Naxos and Cyprus denotes the influence of insularity and rapid change of environmental conditions to the phenology of both species. The annually consistent seasonal activity represents an invariant pattern in continental areas such as Attiki and Samos. Although young and large adults were more abundant than juveniles, the microhabitat preferences of scolopendrids did not differ between the two species and in relation to age class and study site and did not change temporally. The correlation of abundance with high air temperature and low air relative humidity and precipitation shows that both species are thermophilous and xerophilous, well adapted to the environmental conditions of the eastern Mediterranean region.

Critical reflections on German Red Lists of endangered myriapod species (Chilopoda, Diplopoda) (with species list for Germany) https://ijm.pensoft.net/article/1913/ International Journal of Myriapodology 6: 85-105

DOI: 10.3897/ijm.6.2175

Authors: Karin Voigtländer, Hans Reip, Peter Decker, Joerg Spelda

Abstract: The Red Lists of endangered species published by the German Bundesamt für Naturschutz (BfN - the Federal Agency of Nature Conservation) are essential tools for the nature protection in Germany since the 1970s. Although many groups of insects appear in the German Red Lists, small and inconspicuous soil organisms, among them millipedes and centipedes, have in the past been ignored. In the last few years great efforts have been made to assess these two groups, resulting in Red Lists of German Myriapoda. However, difficulties were encountered in strictly applying the Red List classification criteria to myriapods. Here we discuss those problems and some sources of error. A species list of all German Diplopoda and Chilopoda including Red List status and frequency of occurrence is provided in an Appendix.

Preferences of common Central European millipedes for different biotope types (Myriapoda, Diplopoda) in Saxony-Anhalt (Germany) https://ijm.pensoft.net/article/1914/ International Journal of Myriapodology 6: 61-83

DOI: 10.3897/ijm.6.2172

Authors: Karin Voigtländer

Abstract: Knowledge of habitat preferences of myriapod species is essential for their optimal use in bioindication and biological soil assessment. To increase our knowledge a sampling project was started in Saxony-Anhalt (Eastern Germany) more than 20 years ago. The narrowly defined geographic area was selected for the study because the fauna of this Central European German region represents to a high degree the whole of the Central European fauna. The millipede fauna at 175 sites belonging to 12 biotope types was sampled by pitfall trapping and identified to species. According to plant associations, these sites could be divided into four groups differing in moisture and into two groups differing in the level of vegetation cover. Considering the distribution pattern of 28 selected millipede species in each of these groups (weighted percentage), ecological categories of these species could roughly be distinguished. “Main Preferences” separated open land or woodland species and hygrobiont or xerobiont species. The number (and quality) of the occupied biotope types allowed assessment as stenotopic or eurytopic species (“General Preferences”). If available, a “Special Preference” for a preferred biotope type was recognised. For several species, the results are compared with those in the literature.

Behaviour of pill millipedes can be affected by external marking https://ijm.pensoft.net/article/1915/ International Journal of Myriapodology 6: 51-60

DOI: 10.3897/ijm.6.2182

Authors: Táňa Drahokoupilová, Ivan Tuf

Abstract: External or internal marking techniques are often used in various studies of invertebrates to distinguish individuals. Although the potential influence of marking agents on survival is often evaluated, a possible effect on behaviour is usually neglected. We evaluated the influence of two external marking agents (nail polish and bee marker) on behaviour of the pill millipedes, Glomeris tetrasticha, in laboratory. Behaviour was examined from two points of view: (1) specific expressions of behaviour (feeding, exploring, resting and hiding) through 24 hours and (2) activity through 24 hours. The nine-day experiment compared behaviour between groups marked with nail polish or bee marker and the control group. Although there was no observed influence of marking on survival, there was an evident influence on the frequency of feeding, resting and hiding. An effect on frequency of exploring was significant in the marker-marked group only. Marked individuals of G. tetrasticha also differed from the control group in overall activity. They were less active overall and preferred resting and hiding. G. tetrasticha were found to be quite active during almost the whole day in the laboratory, with maximum feeding behaviour in the early morning.

Structure of mandibles in relation to trophic niche differentiation in a tropical millipede community https://ijm.pensoft.net/article/1916/ International Journal of Myriapodology 6: 37-49

DOI: 10.3897/ijm.6.2214

Authors: Irina Semenyuk, A.V. Tiunov, Sergei Golovatch

Abstract: Isotopic composition of nitrogen in 19 species of Diplopoda from a tropical monsoon forest (Cat Tien National Park, southern Vietnam) which supports one of the most diverse millipede faunules globally (no less than 36 species from 17 families and 11 orders) forms a wide continuum of δ15N values ranging from -2.4 to +6.8‰. This suggests a trophic niche differentiation among species. Variation in mouthpart structure could presumably reflect the different foods consumed by species representing at least higher taxa (families and orders). The fine structure of the mandibles in ten sympatric, mostly even syntopic species of Diplopoda does differ considerably between the higher taxa, but neither at the generic nor species level. Neither clear-cut trends in nor evident morphological patterns of, nor significant correlations between the structure of mandibles in Diplopoda species that have different isotopic compositions of nitrogen and presumably exploit different food resources, have been revealed.

Meeting between kingdoms: discovery of a close association between Diplopoda and Bryophyta in a transitional Andean-Pacific forest in Colombia https://ijm.pensoft.net/article/1917/ International Journal of Myriapodology 6: 29-36

DOI: 10.3897/ijm.6.2187

Authors: Shirley Daniella Martínez-Torres, Álvaro Eduardo Flórez Daza, Edgar Leonardo Linares-Castillo

Abstract: In a Nature Reserve called Reserva Natural Río Nambí (Nariño, Colombia), a platyrhacid millipede population of Psammodesmus bryophorus Hoffman, Martínez & Flórez, 2011 was discovered with 10 epizoic bryophyte species from five families: Fissidentaceae, Lejeuneaceae, Metzgeriaceae, Leucomiaceae and Pilotrichaceae. The inspected sample included 22 P. bryophorus individuals of which 15 were carrying mosaics of different bryophyte species on their dorsa, principally Lepidopilum scabrisetum, Lejeunea sp. 1 and Fissidens weirii. This finding constitutes the first record of epizoic plants on Diplopoda.

Trans-segmental serial colour patterns in millipedes and their developmental interpretation (Diplopoda) https://ijm.pensoft.net/article/1918/ International Journal of Myriapodology 6: 1-27

DOI: 10.3897/ijm.6.1949

Authors: Henrik Enghoff

Abstract: Trans-segmental serial colour patterns, i.e., colour patterns consisting of repeated elements, each of which covers several diplosegments / body rings, are described from several millipede taxa: Centrobolus vastus (Attems, 1934) var. sexfasciatus Lawrence, 1967 (Spirobolida: Pachybolidae), Sagmatostreptus strongylopygus (Attems, 1950) (Spirostreptida, Spirostreptidae), and several groups of the order Platydesmida. The occurrence of similar patterns in Siphonocryptus zigzag Enghoff, 2010 (Siphonocryptida, Siphonocryptidae) and unidentified species of the order Chordeumatida is recorded. The patterns are shown in most cases to correlate with postembryonic growth, anamorphosis, i.e., each pattern elements corresponds to a set of diplosegments added during a moult.

A review of the centipede genus Tidops Chamberlin (Scolopendromorpha, Scolopocryptopidae, Newportiinae) https://ijm.pensoft.net/article/1907/ International Journal of Myriapodology 5: 63-82

DOI: 10.3897/ijm.5.1649

Authors: Amazonas Chagas Junior

Abstract: The neotropical genus Tidops Chamberlin, 1915 is reviewed and its geographical distribution is extended. The genus is now composed of four species – T. simus Chamberlin, 1915, T. collaris (Kraepelin, 1915), T. balzanii (Silvestri, 1895), and a new species described from the state of Bahia, in Brazil, named as Tidops nisargani. An amended diagnosis for each species is given. The monotypic genus Kartops Archey, 1923 was examined for the first time and the species K. guianae Archey, 1923 shown to be conspecific with T. collaris, and is therefore a junior synonym of T. collaris. The type species, T. simus, which was only known from Grenada, Lesser Antilles, is recorded for the first time from Brazil, T. balzanii from Bolivia and T. collaris from Venezuela, respectively.

Centipedes (Myriapoda, Chilopoda) of Biologia Centrali-Americana: Current status of the names https://ijm.pensoft.net/article/1908/ International Journal of Myriapodology 5: 55-62

DOI: 10.3897/ijm.5.1865

Authors: Fabio Cupul

Abstract: For the last 100 years, Biologia Centrali-Americana has been an important source of information for many groups of Mexican and Central American arthropods and remains a keystone for taxonomic work. However, many included names are now out of date. I provide an updated list of names of Chilopoda as cited in Vol. 14 of Biologia Centrali-Americana to use as a complement to that work. The Chilopoda of Biologia Centrali-Americana included 52 names for 51 species and 1 subspecies. Of those, 18 names (35%) were described as new in Pocock´s work. Currently 24 remain as valid names in the same genus, 17 have been transferred to other genera and 11 have been treated as synonyms.

Molecular phylogeography of the troglobiotic millipede Tetracion Hoffman, 1956 (Diplopoda, Callipodida, Abacionidae) https://ijm.pensoft.net/article/1910/ International Journal of Myriapodology 5: 35-48

DOI: 10.3897/ijm.5.1891

Authors: Stephanie Loria, Kirk Zigler, Julian Lewis

Abstract: More than 85 species of cave-obligate (troglobiotic) millipede have been described from North America. Understanding the patterns and processes that determine their distribution in this region is an area of recent research. Here, we present the first molecular phylogeographic study of troglobiotic millipedes. Millipedes of the genus Tetracion Hoffman, 1956 (Callipodida: Abacionidae) inhabit caves on the Cumberland Plateau in Tennessee and Alabama, a global hotspot for cave biodiversity. Three species have been described: T. jonesi Hoffman, 1956, T. antraeum Hoffman, 1956, and T. tennesseensis Causey, 1959. To examine genetic divergence within and between species of Tetracion we sequenced part of the mitochondrial cytochrome oxidase 1 gene from 53 individuals from eleven caves across the range of T. tennesseensis and in the northern part of the range of T. jonesi. We found: (1) little variation within species (six haplotypes in T. tennesseensis and four haplotypes in T. jonesi, with a maximum of 1.4% intraspecific divergence between haplotypes), (2) that gene flow between caves is limited (7 of 10 haplotypes were restricted to a single cave, and FST > 0.80 and P < 0.05 for fifteen of eighteen comparisons between caves), and (3) significant genetic divergence between species (8.8% between T. tennesseensis and T. jonesi). Our results are consistent with previous morphology-based species definitions showing T. tennesseensis and T. jonesi belonging to distinct taxa. Our research contributes to the growing body of phylogeographic information about cave species on the Cumberland Plateau, and provides a point of comparison for future studies of troglobionts and millipedes.

A review of the species in the genus Cryptops Leach, 1815 from the Old World related to Cryptops (Cryptops) hortensis (Donovan, 1810) (Chilopoda, Scolopendromorpha) https://ijm.pensoft.net/article/1905/ International Journal of Myriapodology 4: 11-50

DOI: 10.3897/ijm.4.1116

Authors: John Lewis

Abstract: The subgenus Cryptops may be divided into those species with, and those without, an anterior transverse suture on tergite 1. The latter group may be further separated into species with the ultimate leg femur without a saw tooth or teeth (here termed the hortensis group) and those with one or more (here termed the doriae group). The species of the Old World of the hortensis group are the subject of this paper. Where possible, the non-European type material has been examined and data for European species added from the literature. C. omissus Ribaut, 1915 (Kenya), C. mirus Chamberlin, 1920 (Tahiti) and C. arapuni Archey, 1922 (New Zealand), lacking ultimate legs cannot be assigned to either the hortensis or the doriae group. C. inermipes Pocock, 1888, which lacks saw teeth on the ultimate legs is considered here. C. nanus Attems, 1938 (Hawaii), C. navis Chamberlin, 1930 (Singapore), C. philammus Attems, 1928 (Southern Africa), C. sinesicus Chamberlin, 1940 (China), C. stupendus Attems, 1928 (South Africa) and C. tahitianus Chamberlin, 1920 (Tahiti) appear from their descriptions to belong to the hortensis group but have a prefemoral saw tooth or teeth and thus belong to the doriae group. The following species are regarded as valid: C. covertus Chamberlin, 1951, C. daszaki Lewis, 2002, C. decoratus Lawrence, 1960, C. hortensis (Donovan, 1810), C. inermipes Pocock, 1888, C. lobatus Verhoeff, 1931, C. mauritianus Verhoeff, 1937, C. melanotypus Chamberlin, 1941, C. nigropictus Takakuwa, 1936, C. parisi Brolemann, 1920, C. songi Song et al., 2010 and C. stabilis Chamberlin, 1944. Examination of further material is required to establish the true status of C. brignolii Matic, 1977, currently regarded as valid. C. hortensis atlantis Pocock, 1891 is returned to full specific status as C. atlantis. C. basilewskyi Matic & Darabantu, 1977, C. kalobensis Goffinet, 1971 and C. niloticus Lewis, 1967 are junior subjective synonyms of C. nigropictus. C. penicillatus Lawrence, 1960 is a junior subjective synonym of C. decoratus and C. decoratus sensu Lewis (from Mauritius and Seychelles) is a junior subjective synonym of C. melanotypus. C. parisi cottarellii Matic, 1977, and C. parisi rhenanus Verhoeff, 1931 are junior subjective synonyms of C. parisi. C. campestris Attems, 1953, C. compositus Chamberlin, 1952, C. medius Verhoeff, 1901, C. orthus Chamberlin, 1951, C. parisi sebini Verhoeff, 1934 and C. philammus gabonensis Demange, 1968 are regarded as nomina dubia. A key is provided to the fourteen species considered valid. However, the status of four of them, namely C. nigropictus, C. decoratus, C. melanotypus and C. songi, which are very similar, and the species that have been here synonymised with them, is uncertain. More material and more refined techniques are required to ascertain their exact status. Whatever that is, however, there can be little doubt that we are dealing with some closely related and very widely distributed populations. This suggests that Cryptops species are easily dispersed over large distances.

Glomerin and homoglomerin from the North American pill millipede Onomeris sinuata (Loomis, 1943) (Diplopoda, Pentazonia, Glomeridae) https://ijm.pensoft.net/article/1906/ International Journal of Myriapodology 4: 1-10

DOI: 10.3897/ijm.4.1105

Authors: William Shear, Tappey Jones, Thomas Wesener

Abstract: Specimens of the North American glomerid millipede Onomeris sinuata (Loomis, 1943) were collected at the type locality in Alabama, USA, and maintained briefly in the laboratory in native leaf litter. The millipedes could not be induced to produce defensive secretions by rough handling, tapping, squeezing or leg-pinching. Four specimens were extracted in methanol and the extract analyzed using gas chromatography/mass spectroscopy. The analysis revealed the alkaloids glomerin and homoglomerin, previously reported as components in the defensive secretion of the European glomerid Glomeris marginata (Villers, 1789). This report is only the second for the occurrence of quinazolinone alkaloids in animals.
