The Florida State Collection of Arthropods (FSCA) is one of the top insect collections in the United States with in excess of eight million curated specimens and significant amounts of materials in bulk collections and other unprocessed samples. The subphylum Myriapoda currently comprises approximately 17,500 species in the four classes Diplopoda, Chilopoda, Symphyla, and Pauropoda. The FSCA houses type material in the Diplopoda orders Callipodida, Chordeumatida, Glomeridesmida, Julida, Polydesmida, Polyzoniida, Siphonophorida, Spirobolida, and Spirostreptida. This catalog documents the FSCA primary type material for 74 species in 45 genera in 25 families and nine orders within Diplopoda.

TROPOSTREPTUS PHYLOGENY AND EVOLUTION Twenty-one of our included mitochondrial genomes belong to Tropostreptus, allowing for a thorough investigation of the evolution of this genus in the Eastern Arc. We observe a clear genetic structure in Tropostreptus, with distinct lineages (both inter- and intraspecific) being defined by the mountain blocks (Fig. 4). This is consistent with previous genetic results of Eastern Arc gene pools (e.g. cat snakes: Gravlund, 2002; chameleons: Tolley et al., 2011; African violets: Dimitrov et al., 2012), where forestadapted species inhabit the montane forests and are absent from the adjacent savannah lowlands. Today, the mountains capture the oceanic winds from the Indian Ocean, which maintains sufficient humidity for dense rain forest to grow, resulting in the forest ‘sky islands’ (Lovett, 1993a, b; Burgess et al., 2007). Until 30 Mya, the Eastern Arc region is thought to have been covered by rain forest (Rodgers, 1998; Couvreur et al., 2008), and an uplifting of the Eastern Arc Mountains is believed to have occurred within the last 7 Myr (although this is debated), changing the whole topography of East Africa (Griffiths, 1993; Ring, 2014; Macgregor, 2015). Climatic and geological fluctuations through time have thus repeatedly affected the forest cover and, presumably, resulted in a multitude of vicariance events when species were isolated in patchy forest remnants (Lovett, 1993a; Sepulchre et al., 2006; Couvreur et al., 2008). For these reasons, the splitting order we observe in the Tropostreptus phylogeny might well reflect forest fragmentation in ancient times. We observe a general trend, whereby northern lineages appear to split off first. The earliest split in Tropostreptus separates the Tropostreptus austerus + Tropostreptus severus lineage from the rest, and the second split separates these two species, today occupying Nguru and Usambara Mountains in the north. A similar intraspecific pattern is evident in more recent splits in Tropostreptus hamatus and Tropostreptus sigmatospinus (Fig. 4), suggesting a repeated pattern of vicariance events occurring first in the north. A separation of species between northern and southern mountains has also been observed in several other Eastern Arc taxa, including amphibians (Blackburn & Measey, 2009), gastropods (Tattersfield et al., 1998) and reptiles (Gravlund, 2002; Tolley et al., 2011), but also in well-dispersing taxa, such as birds (Fjeldså & Bowie, 2008). This indicates a forest retraction southwards during dry periods, resulting in vicariance events, followed by forest expansion and thus northward recolonization of species during periods with higher humidity. Northward migration is also observed in other Eastern Arc species, such as chameleons (Tolley et al., 2011; Ceccarelli et al., 2014). A recent cycle of forest expansion/retraction can explain why Tropostreptus hamatus and Tropostreptus sigmatospinus exist across several of the mountains without having evolved into distinct species yet. Other events have isolated Tropostreptus kipunji in the forest on Mount Rungwe, the most south-westerly occurring species in the Eastern Arc region, in addition to Tropostreptus sigmatospinus in Zanzibar and, potentially, also the Rondo Plateau, from where Tropostreptus has been observed but for which molecular data are still lacking (Enghoff, 2017). Regarding the timing of the species splits (Fig. 5), several major events might have played a role. Around 30 Mya the Antarctic ice sheet started to form (Couvreur et al., 2008), along with rifting that started to occur in northern East Africa (Ring, 2014), possibly initiating the fragmentation of the pan-African forest. Through millions of years, the rifting would continue southwards (Ring, 2014), affecting the topology and possibly related to the forest fragmentation responsible for the divergence of Tropostreptus austerus and Tropostreptus severus observed ~22 Mya. The observed divergence of Tropostreptus hamatus and the split between Tropostreptus austerus and Tropostreptus severus correspond well to the closing of the Tethys Sea (17 Mya), which would have altered ocean currents and, probably, the climate of the area (Couvreur et al., 2008). Likewise, the isolation of the Tropostreptus kipunji lineage corresponds with the uplifting of Mount Rungwe from ~8 Mya (Ring, 2014). Finally, between 5 Mya and today, we observe a radiation in Tropostreptus hamatus and Tropostreptus sigmatospinus (Fig. 5). A reasonable explanation for this is the uplift of the Eastern Arc Mountains, shifting the precipitation from the lowlands to the mountains (Lovett, 1993a, b), in combination with the Antarctic ice sheet forming, thus decreasing global humidity (Polyak et al., 2010). This would lead to the emergence of savannah in the lowlands between the mountains (Sepulchre et al., 2006; Ségalen et al., 2007; Couvreur et al., 2008), isolating the montane forest and limiting migration between populations of forest-restricted species. We emphasize that we have neither good fossil records nor mtDNA mutation rates estimated specifically for millipedes, which is why the split times of our millipede phylogenetic tree should be interpreted with caution. Moreover, comparable studies with dated phylogenies of Eastern Arc species are sparse, hence it is difficult to compare the split times we have estimated with those of other species in the region. Examining two separate studies of chameleons (Kinyongia Tilbury, Tolley & Branch, 2006 and Trioceros Swainson, 1839) with dated phylogenies based on both mitochondrial and nuclear markers did show some correspondence with our dated splits (Tolley et al., 2011; Ceccarelli et al., 2014). Tolley et al. (2011) dated the earliest split between the northern and southern Eastern Arc species to ~28 Mya, and both studies show several radiation events between 5 and 20 Mya, corresponding to the same overall time frame that we are discussing for the millipedes. In contrast, the chameleons display fewer speciation events during the last 5 Myr than the millipedes, perhaps suggesting that the latter have been more susceptible to vicariance during more recent climatic events., Published as part of Nielsen, Martin, Margaryan, Ashot, Nielsen, Tejs Lind, Enghoff, Henrik & Allentoft, Morten E., 2022, Complete mitochondrial genomes from museum specimens clarify millipede evolution in the Eastern Arc Mountains, pp. 924-939 in Zoological Journal of the Linnean Society 196 (2) on pages 933-934, DOI: 10.1093/zoolinnean/zlac058, http://zenodo.org/record/7184588, {"references":["Gravlund P. 2002.

Millipedes are widely distributed in Saudi Arabia but they were not studied before. In Taif governorate, two species were found that are similar morphologically, which resulted in incorrect identif...

During a soil zoological expedition to São Tomé and Príncipe in 2010 by the California Academy of Sciences, millipedes of the genus Globanus were collected. Samples of G. marginescaber (Karsch, 1884) and G. integer (Karsch, 1884) were recovered in addition to those containing a new species. Globanus drewesisp. nov. is described and additional records, illustrations, and descriptive notes are given for the other two species. A key to all three species of the genus is provided, and a distribution map is presented. The monotypic genus Lobogonus Demange, 1971, which includes L. trilobatus Demange, 1971, from Sierra Leone, mainland western Africa, is revalidated and removed from synonymy under Globanus. Lobogonus is illustrated from a type specimen.

The Eastern Arc Mountains in Tanzania represent a hotspot for biological diversity of global importance. The level of endemism is high, and Eastern Arc biodiversity has been studied extensively in vertebrates and invertebrates, including millipedes. However, millipede evolution is vastly understudied at the molecular level. Therefore, we used next-generation ‘shotgun’ sequencing to obtain mitochondrial genome sequences of 26 museum specimens, representing six genera and 12 millipede species found across the Eastern Arc Mountains. Bayesian and maximum likelihood methods yielded consistent topologies with high node support, confirming a high level of congruence between molecular and morphological analyses. The only exception was a Tropostreptus sigmatospinus individual from Zanzibar, which was placed outside an otherwise monophyletic group consisting of mainland individuals of the same assumed species. For two species with a distribution across several mountain blocks (Tropostreptus sigmatospinus and Tropostreptus hamatus), each mountain population represents a distinct monophyletic lineage. In contrast, we also observe that distinct species exist sympatrically in the same montane forests, indicative of older speciation events that are not defined by current forest distribution. Our results are important for understanding speciation mechanisms in montane rain forests and highlight that ethanol-preserved invertebrates exhibit a tremendous potential for genomic analyses.

Male gonopods are useful in taxonomic diagnoses and descriptions of millipedes, although they may vary intraspecifically in shape and size. To assess this intraspecific variation, we used geometric morphometric analysis to compare gonopod morphology among eight isolated populations of the colour-polymorphic southern African millipede Bicoxidens flavicollis. Our results showed that gonopod shapes vary significantly across the examined populations, and elucidated subtle variations. CVA cross-validation test indicates an average classification rate of 75% for the five populations for which we had more than one specimen. Although we had a small number of replicates for three populations, our results still illustrate the importance of applying quantitative approaches to what would otherwise be qualitative and subjective gonopod shape categories in millipedes. As such, the taxonomic assignment of the populations of B. flavicollis may require further investigation, and further revisions would be required with an integrative approach, including molecular data, in order to re-evaluate the taxonomic diversity and distribution data of this species. Finally, we highlight the conservation potential of divergent populations as evolutionary insurance against a dynamic and unpredictable climate, whether or not they undergo full speciation.

A new millipede species of the genus Sechelleptus Mauriès, 1980 is described and illustrated from Mayotte Island, Indian Ocean. This new species, S. arborivagus sp. nov., found on trees, looks particularly similar to the sympatric S. variabilis VandenSpiegel & Golovatch, 2007, but is much larger and has a very different ecological behavior. Phylogenetic analyses based on a concatenated dataset of the COI and 16S rRNA genes and including nine species of Spirostreptidae (including Sechelleptus, Doratogonus Attems, 1914, Bicoxidens Attems, 1928 and Spirostreptus Brandt, 1833), strongly support the monophyly of Sechelleptus. Despite the similarity of their genitalia, the molecular analyses also reveal a clear-cut genetic divergence between S. arborivagus sp. nov. and S. variabilis (22.55% for COI and 6.63% for 16SrRNA) and further suggest the presence of a higher diversity within the genus Sechelleptus on Mayotte.

Sechelleptus arborivagus sp. nov. urn:lsid:zoobank.org:act: 0F7B3368-17F8-4CAD-8B11-C34B564FE8DE Figs 3���8 Diagnosis A medium-sized arboreal millipede with relatively long legs, particularly similar to S. variabilis by sharing the structure of the male first leg and rather simple gonopods with the metaplica widened and a little higher than proplica, the latter without lateral cone. The two species differ by the gonotelopodite being apically divided in two branches in S. arborivagus sp. nov. and simple in S. variabilis. Etymology Referring to the ecology of the species, which has always been observed climbing trees. Material examined Holotype FRANCE ��� Department of Mayotte (Comoros archipelago) ��� ♂; Mt.

First pair of male legs with a well-developed prefemoral process ending in an inward curved tip (Fig. 5A). Coxosternum with a laterobasal field of four strong setae on anterior side. GONOPODS (Figs 5B���E, 6). Sternum (st) triangular, not reaching as far distad as paracoxite (px). Metaplica (mp) higher than proplica, rounded apically (Fig. 5C; mp). Proplica with straight sides, in apical part with scattered short setae, ending apically in a more or less spiniform mesapical projection (Fig. 5C; mpp) and a well-developed, apicolateral, lamellose lobe (Fig. 6C; al); telopodite (Fig. 5B, E; tlp) long and slender, without a distinct demarcation between femoral and postfemoral parts, femorite with a small and pointed antetorsal process (Fig. 5E; ats), postfemorite spiralled, ribbon-shaped, broad and long, with a divided tip, the longer branch carrying the terminal opening of the solenomere (Fig. 5B; sl). Paratypes Male similar to holotype. Female coloration as in male, but generally larger in size than male (up to 120 mm long 9 mm wide (58���61 body rings plus telson, no apodous rings). Vulvae located in membranous pouches attached to coxae 2 and 3 and to the inner lateral margin of ring 1, simple, consisting of two simple, subequallysized, moderately sclerotized valves, the aboral valve with an apical cluster of setae; ridge between valves covered with a lateral longitudinal operculum (Fig. 7). Distribution The species seems endemic to Mayotte (Fig. 8). Affinities On the basis of the gonopod structure having the telopodite with a spine arising well distad of the knee, a ribbon-shaped distal part, and a small free solenomerite arising just near the apex, the new species is manifestly a new member of the large genus Sechelleptus. Following the key published by Jeekel in 1999, arborivagus keys out close to sulcicollis and macilentus. Indeed the three species have a rather simple gonocoxite with a distally widened metaplica without a strong lateral cone but the new species do not show the small lateral uncus present on the metaplica of sulcicolis and possess a more or less spiniform mesapical projection on the proplica which is not present in sulcicolis neither in macilentus. By the overall shape of the male first leg and gonocoxite, the new species seems to be especially close to S. variabilis, also from the Comoros, but it differs strikingly by the structure of the gonotelopodite (in S. variabilis the gonotelopodite has a simple and pointed tip carrying the terminal opening of the seminal groove whereas in the new species the gonotelopodite has a divided tip, the longer branch carrying the terminal opening of the seminal groove) as well as by the larger body size and the longer and curved claws (Fig. 4K vs Fig. 2C). Other important differences concern the defensives glands, large in S. arborivagus sp. nov. (Fig. 4I) (vs inconspicuous in S. variabilis (Fig. 2A)), and the size of eyes: in the new specie the eyes are larger and include 60 �� 5 ommatidia (n = 10) arranged in 12 rows; whereas in S. variabilis the eyes, smaller, include 34 �� 3 (n = 10) ommatidia arranged in 9 rows. Natural history Most of the specimens belonging to the new species were collected on Mt Tchaourembo (see Fig. 8) in a forest fragment at 500���550 m a.s.l. All specimens were seen in trees and never in pairs, the males being rare (sex ratio> 1/6). The species possesses enlarged ommatidia, relatively long legs with strongly curved tarsal claws, as well as a tendency for specimens to secrete extremely copiously from their defensive glands when irritated. Such modifications are considered by several authors as an adaptation to tree climbing and to arboreal life (Enghoff & Enghoff 1976; Hoffman & Howell 1983; VandenSpiegel 2001). Discussion Millipede systematics is mainly based on male gonopods because they use to be species-specific (Bond et al. 2003). However, studies based on DNA have demonstrated that molecular divergence in different millipede groups may not reflect divergence in morphology-based identifications and may hide considerable variation (Bond & Sierwald 2002; Bond et al. 2003; Adams et al. 2009; Mwabvu et al. 2013, 2015; Tinago et al. 2017). Although our relatively small taxon sampling, the phylogenetic analysis strongly recovers Sechelleptus as monophyletic and discriminates at least two or three different groups. Furthermore, the mean inter-specific distance values (14.9% for COI and 5.1% for 16S) were remarkably similar to previous studies that reported the presence of high genetic divergence among population of different spirostreptid species (Mwabvu et al. 2013, 2015), suggesting the existence of more than one species in those taxa. It is argued that high level of divergence between identified spirostreptid species may indicate that changes in genital morphology occur rather slowly relative to the high rate of substitution in mitochondrial sequences (especially for COI), and may underestimate species diversity. This also appears to be the case among the different forms of Mayottan Sechelleptus, which also share strongly similar gonopods. At the first glance, the new species of Sechelleptus seems to be a giant form of S. variabilis. However, although only subtle morphological differences are observed within the gonopods, the comparatively large body size and the behavior of S. arborivagus sp. nov. are remarkable. These observations finally corroborate our molecular analyses that clearly show sufficient genetic difference between the different Sechelleptus species collected on Mayotte (22.6% for COI and 6.6% for 16S between S. arborivagus sp. nov. and S. variabilis). The genetic analyses also suggest the presence of another different species, i.e., DU1, although its phylogenetic position remains unresolved. This unique specimen found at Mont Combani is a sub-adult female that could not allow a formal identification, but, judging from its general appearance, appears to be an intermediate from between the two Sechelleptus species collected on Mayotte. The genetic divergences, along with adaptations to arboreal life observed in the novel species, may indicate an ���adaptive micro-radiation��� on Mayotte Island or even the Comoros. However, the inclusion of more specimens, including adult males, in phylogenetic analyses is needed to test this hypothesis and evaluate the status of that putative new species., Published as part of Vandenspiegel, Didier, Henrard, Arnaud & Mathys, Aurore, 2021, Sechelleptus arborivagus sp. nov., a new arboreal spirostreptid millipede (Diplopoda, Spirostreptidae) endemic to Mayotte Island (Comoros Archipelago), Indian Ocean, pp. 1-21 in European Journal of Taxonomy 755 (1) on pages 8-16, DOI: 10.5852/ejt.2021.755.1395, http://zenodo.org/record/4966001, {"references":["Enghoff I.

Methanogens represent the final decomposition guild in anaerobic degradation of organic matter, occurring in digestive tract of various invertebrates. However, factors determining their community structure and activity in distinct gut sections is still debated. In this study, we focused on the tropical millipede species Archispirostreptus gigas (Diplopoda, Spirostreptidae) and Epibolus pulchripes (Diplopoda, Pachybolidae), which release considerable amounts of methane. We aimed to characterize relationships between physicochemical parameters, methane production rates, and methanogen community structure in the two major gut sections, midgut and hindgut. Microsensor measurements revealed that both sections were strictly anoxic, with reducing conditions prevailing in both millipedes. Hydrogen concentration culminated in anterior hindgut of E. pulchripes In both species, the intestinal pH was significantly higher in the hindgut than in the midgut. An accumulation of acetate and formate in the gut indicated bacterial fermentation activities in the digestive tract of both species. Phylogenetic analysis of 16S rRNA genes showed a prevalence of Methanobrevibacter spp. (Methanobacteriales), accompanied by a small fraction of so far unclassified "Methanomethylophilaceae" (Methanomassiliicoccales), in both species, which suggests that methanogenesis is mostly hydrogenotrophic. We conclude that anoxic conditions, negative redox potential, and bacterial production of hydrogen and formate promotes the gut colonization by methanogens. The higher activities of methanogens in the hindgut are explained by the higher pH of this compartment and their association with ciliates, which are restricted to this compartment and present an additional source of methanogenic substrates.ImportanceMethane (CH4) is the second most important atmospheric greenhouse gas after CO2 and is believed to account for 17% of global warming. Methanogens are a diverse group of archaea and can be found in various anoxic habitats including digestive tract of plant-feeding animals. Termites, cockroaches, the larvae of scarab beetles, and millipedes are the only arthropods known to host methanogens and emit large amounts of methane. Millipedes are ranked third most important detritivores after termites and earthworms, and they are considered keystone species in many terrestrial ecosystems. Both methane producing and non-emitting species have been observed in millipedes, but what limits their methanogenic potential is not known. In the present study, we show that physico-chemical gut conditions and the distribution of symbiotic ciliates are important factors determining CH4 emission in millipedes. We also find great similarities to other methane-emitting arthropods, which might be associated with their similar plant-feeding habits.

Genus Odontostreptus Attems, 1914 Diagnosis (based on Krabbe 1982) Differs from other genera of Spirostreptidae by having a gonopod telopodite with an antetorsal process and a terminal, large, ladle-like lamella protecting an unbranched solenomere, in combination with having a simple gonopod coxal metaplica without terminal lamellae, moderately developed prefemoral processes on the first pair of male legs, a dorsally smooth preanal ring, and body rings without longitudinal keels. Of the 13 included species (Krabbe 1982), two are restricted to Morocco, viz., O. maroccanus (Attems, 1914) and O. lepineyi (Verhoeff, 1938). The latter is very poorly known; it was described from a female and according to Schubart (1960) may be a synonym of O. maroccanus tidsiaccola. In contrast, O. maroccanus has been collected frequently. In its present concept it is quite a variable species; the following forms have been described: - O. maroccanus tidsiaccola (Brolemann, 1928) - O. maroccanus ahmedensis (Brolemann, 1928) - a form of ahmedensis with particularly many body rings (Schubart 1960) - a form of ahmedensis (���Rif-Form���) with ozopores on body ring 5 (Schubart 1960) Schubart (1952, 1960) considered the possibility that ahmedensis could be a separate species. We here present some notes and illustrations of O. maroccanus s. lat., but a clarification must await a study of a much more comprehensive material. On the other hand, we are confident in describing the new eyeless Odontostreptus as a separate species., Published as part of Enghoff, Henrik & Reboleira, Ana Sofia, 2020, The first blind spirostreptid millipede, found in a cave in Morocco; with notes on the genus Odontostreptus Attems, 1914 (Diplopoda, Spirostreptida, Spirostreptidae), pp. 1-11 in European Journal of Taxonomy 668 on page 2, DOI: 10.5852/ejt.2020.668, http://zenodo.org/record/3900281, {"references":["Attems C. 1914.

Genus Attemsostreptus Verhoeff, 1941 Diagnosis Readily distinguishable from other genera of Spirostreptidae by the extremely long, slender lateral metaplical processes, in combination with the ���trachystreptinine��� habitus, i.e., with marked longitudinal striae/keels over the entire body ring circumference. Krabbe (1982) presented a more detailed diagnosis, based mainly on male secondary sexual characters, as follows (translated from German and slightly modified): collum without longitudinal keels. First pair of legs with strong ���shoulders���; the outer margin of the coxosternum smooth with 4 lateral small setae; prefemoral processes divergent, short, triangular with gently rounded margins, prefemora and prefemoral processes with pores. Gonopod sternum low and small; coxae slender, proplica (pp) simple, straight, bearing a few setae distally; metaplicae (mp) apically round to angular with extremely elongated lateral processes (lap) tapering into a claw-like apex, distally round to subrectangular; telopodite slender with a long, thin antetorsal process (atp), distal to (atp) becoming even slenderer, apex bifurcate with a thin serrated lamella and an acuminate apical process.
