E-mail: [email protected] 2Instituto de Ciencias Naturales,Universidad Nacional de Colombia, Edificio 425, Oficina 105, Bogotá, Colombia. E-mail: [email protected] Abstract In the New World, the milliped family Platyrhacidae (Polydesmida) is known or projected for Central America south of southeastern Nicaragua and the northern ¼ of South America, with disjunct, insular populations on Hispaniola (Haiti), Guadeloupe (Basse-Terre), and St. Lucia. Male near-topotypes enable redescription of Proaspis aitia Loomis, 1941, possibly endemic to the western end of the southern Haitian peninsula. The tibiotarsus of its biramous gonopodal telopodite bends strongly laterad, and the medially directed solenomere arises at midlength proximal to the bend. With a uniramous telopodite, P. sahlii Jeekel, 1980, on Guadeloupe, is not congeneric, and Hoffmanorhacus, n. gen., is erected to accommodate it. Nannorrhacus luciae (Pocock, 1894), on St. Lucia, is redescribed; also with a biramous telopodite, its tibiotarsus arises distad and diverges from the coaxial solenomere.

  • Apheloria Polychroma, a New Species of Millipede from the Cumberland Mountains (Polydesmida: Xystodesmidae) PAUL E. MAREK1*
    Apheloria polychroma, a new species of millipede from the Cumberland Mountains (Polydesmida: Xystodesmidae) PAUL E. MAREK1*, JACKSON C. MEANS1, DEREK A. HENNEN1 1Virginia Polytechnic Institute and State University, Department of Entomology, Blacksburg, Virginia 24061, U.S.A. *Corresponding author, email: [email protected] Abstract Millipedes of the genus Apheloria occur in temperate broadleaf forests throughout eastern North America and west of the Mississippi River in the Ozark and Ouachita Mountains. Chemically defended with toxins made up of cyanide and benzaldehyde, the genus is part of a community of xystodesmid millipedes that compose several Müllerian mimicry rings in the Appalachian Mountains. We describe a model species of these mimicry rings, Apheloria polychroma n. sp., one of the most variable in coloration of all species of Diplopoda with more than six color morphs, each associated with a separate mimicry ring. Keywords: aposematic, Appalachian, Myriapoda, taxonomy, systematics Introduction Millipedes in the family Xystodesmidae are most diverse in the Appalachian Mountains where about half of the family’s species occur. In the New World, the family is distributed throughout eastern and western North America and south to El Salvador (Marek et al. 2014, Marek et al. 2017). Xystodesmidae occur in the Old World in the Mediterranean, the Russian Far East, Japan, western and eastern China, Taiwan and Vietnam. Taxa include species that are bioluminescent (genus Motyxia) and highly gregarious (genera Parafontaria and Pleuroloma); some form Müllerian mimicry rings. Despite their fascinating biology and critical ecological function as native decomposers in broadleaf deciduous forests in the U.S., their alpha-taxonomy is antiquated, and scores of new species remain undescribed.

E-mail: [email protected] Received: 10 June 2011; Accepted: 20 July 2011 ABSTRACT.– Faunistic records are provided, summarized and mapped for several smaller families of the millipede order Polydesmida in Taiwan. Both Pyrgodesmidae and Opisotretidae are new to the Taiwanese list. The former family is represented there by the nearly pantropical Cryptocorypha ornata (Attems, 1938) which is new to the island’s fauna, as well as by two new species of Ampelodesmus Miyosi, 1956: A. taiwanensis n. sp. and A. similis n. sp.; both latter taxa are incorporated in a key to all five species of the genus. Cryptodesmidae are actually represented in Taiwan by a single, widespread, briefly redescribed and richly illustrated species, Niponia nodulosa Verhoeff, 1931 (= Onomatoplanus simplexus Wang, 1957, n. syn.), while both Opisotretidae and Xystodesmidae by a closer unidentified species of ?Corypholophus Attems, 1937 and Riukiaria Attems, 1938, respectively. In addition to Eutrichodesmus taiwanensis Golovatch, Mikhaljova, Korsós and Chang, 2010, the family Haplodesmidae contains in Taiwan the almost pantropical Prosopodesmus jacobsoni Silvestri, 1910, thus confirming an earlier record.

E-mail: [email protected] Received: 14 January 2010; Accepted: 1 February 2010 ABSTRACT.– The East Asian to Australasian millipede family Haplodesmidae is reported from Taiwan for the first time on the basis of Eutrichodesmus taiwanensis n. sp. This new species joins the newly established peculiaris-group which also includes the Japanese Eutrichodesmus peculiaris (Murakami, 1966), E. nodulosus (Verhoeff, 1939) and E. silvaticus (Haga, 1968), as well as E. pectinatidentis (Zhang, 1995), E. anisodentus (Zhang, 1995) and E. soesilae Makhan, 2010, this latter trio from continental China. The species group is characterized by complete volvation often showing an unusual overlap pattern which becomes typical from segment 3 or 4, the presence of only two transverse rows of metatergal tuberculations, the broad and dorsoventrally flattened epiproct (sometimes unusually spatuliform in the male), and the gonopods slender, fully to nearly fully devoid of a distofemoral process, but at least sometimes supplied with an accessory seminal chamber.

India E-mail: [email protected] ORCID: 0000-0002-4926-2496 Abstract Mating behaviour of Chondromorpha severini, a polydesmid millipede was studied in the field and in the laboratory condition. Copulating pair follows the general rule of love play before actual act of coitus. Mating duration varied from one to 25 minute with an average of eight minute. Mating frequency was maximum in early and late hours of day. In the multiple mate preference experiment, 10 pairs of male and female were used to calculate preference index (Pi) of individual sex. Preference index varies from 0.65 to 0.91. The implication of multiple mating has been discussed in detail. The study confirmed that i) the species belongs to polygynandrous mating system where males are the pursuers and females are the accomplishers ii) short and long duration mating is related to mate acquisition and mate guarding respectively Keywords: Love play, preference index, polygynandrous, short and long duration mating, triplet formation bioRxiv preprint doi: https://doi.org/10.1101/2020.08.23.263863; this version posted August 24, 2020.

  • Ordinal-Level Phylogenomics of the Arthropod Class
    Ordinal-Level Phylogenomics of the Arthropod Class Diplopoda (Millipedes) Based on an Analysis of 221 Nuclear Protein-Coding Loci Generated Using Next- Generation Sequence Analyses Michael S. Brewer1,2*, Jason E. Bond3 1 Department of Environmental Science, Policy, and Management, University of California Berkeley, Berkeley, California, United States of America, 2 Department of Biology, East Carolina University, Greenville, North Carolina, United States of America, 3 Department of Biological Sciences and Auburn University Museum of Natural History, Auburn University, Auburn, Alabama, United States of America Abstract Background: The ancient and diverse, yet understudied arthropod class Diplopoda, the millipedes, has a muddled taxonomic history. Despite having a cosmopolitan distribution and a number of unique and interesting characteristics, the group has received relatively little attention; interest in millipede systematics is low compared to taxa of comparable diversity. The existing classification of the group comprises 16 orders. Past attempts to reconstruct millipede phylogenies have suffered from a paucity of characters and included too few taxa to confidently resolve relationships and make formal nomenclatural changes. Herein, we reconstruct an ordinal-level phylogeny for the class Diplopoda using the largest character set ever assembled for the group. Methods: Transcriptomic sequences were obtained from exemplar taxa representing much of the diversity of millipede orders using second-generation (i.e., next-generation or high-throughput) sequencing. These data were subject to rigorous orthology selection and phylogenetic dataset optimization and then used to reconstruct phylogenies employing Bayesian inference and maximum likelihood optimality criteria. Ancestral reconstructions of sperm transfer appendage development (gonopods), presence of lateral defense secretion pores (ozopores), and presence of spinnerets were considered.
