An overview of the extant genera and subgenera of the order Scolopendromorpha (Chilopoda): a new identification key and updated diagnoses

Abstract

The extant genera and subgenera of the order Scolopendromorpha are critically reviewed and provided with updated diagnoses and a new identification key; the most recent revisions of scolopendromorph genera are concisely summarised. Rhoda Meinert, 1886 and Cryptops (Chromatanops) Verhoeff, 1906 are suggested to be a junior synonyms of Scolopendropsis Brandt, 1841 and Cryptops (Cryptops) Leach, 1814, respectively. The subgeneric status is formally fixed for Cryptops (Paracryptops) Pocock, 1891 and Cormocephalus (Campylostigmus) Ribaut, 1923; the taxonomic status of the former genus Kanparka Waldock & Edgecombe, 2012 is discussed. As a result of synonymies, the number of scolopendromorph genera and subgenera is currently 37. The formal status of the former tribes Scolopendrini Leach, 1814, Asanadini Verhoeff, 1907 and Arrhabdotini Attems, 1930 is briefly discussed; the presence of the sexual dimorphism among the taxa of generic level is overviewed.

The myriapod fauna (Chilopoda, Diplopoda) of the Truong Sa (Spratly) archipelago, Vietnam

“…However, Siriwut et al (2018) pointed out some obvious features to distinguish between them including differences in paramedian suture on sternites, the presence of dorsal spine on coxopleural process and prefemoral spurs on leg 1. Schileyko et al (2020) re-examined the specimens in Indochina that are kept in the Russian museum, he also agreed with Siriwut.…”

“…Myriapod specimens were morphologically examined using the Olympus microscope SZ61. Species identification follows Bonato et al (2011), Siriwut et al (2016, 2018, Schileyko (2007Schileyko ( , 2014, Schileyko et al (2020), Likhitrakarn et al (2011), Attems (1937) and Shelley & Lehtinen (1999). Images were taken using the camera attached to the microscope, and stacked using the software Helicon Focus ver.…”

“…To date, there are 36 species of the genus Rhysida recorded in the world (Schileyko et al, 2020), and only three species were known in Vietnam (Tran et al, 2013). (Newport, 1845) Rhysida longipes Newport, 1845: 411;Pocock 1891a: 418;Attems, 1938: 337;Schileyko, 2007: 82;Tran et al, 2013: 227;Schileyko & Stoev, 2016: 257, 22-24. Otostigmus (O) simplex Chamberlin, 1913: 75;Attems, 1930: 153;Schileyko, 1998: 269;Schileyko, 2001: 432 , 4B).…”

“…The genus Cryptops has a small size, about 30 mm in maximum length (Schileyko, 2007). It is widely distributed in tropical, subtropical, and warm temperature areas (Schileyko et al, 2020). There are more than 180 species recorded in the world (Bonato et al, 2016).…”

Scolopocryptops zhijinensis sp.n. and a key to species of scolopocryptopine centipedes from China (Scolopendromorpha: Scolopocryptopidae)

“…Scolopocryptops species are blind scolopendromorphs with 23 pairs of legs, and the prefemur of the ultimate legs has one dorsomedial and one ventral spinous process [Chagas-Jr, Bichuette, 2015;Schileyko et al, 2020]. In China, Chao & Chang [2003] reported five species or subspecies from Taiwan: S. capillipedatus (Takakuwa, 1938), S. curtus (Takakuwa, 1939), S. melanostomus melanostomus Newport, 1845 (= S. melanostoma melanostoma Newport, 1845, see Bonato et al [2016]), S. rubiginosus L. Koch, 1878, andS.…”
