Diagnosis. Spiracles (figs 1 AB in Vahtera et al. 2012 b, fig. 5 F in Bonato et al. 2017) on macrosegments, LBS 7 with or without spiracles. Coxopleuron (Fig. 37) usually with a spine at the place of corresponding process. Prefemur and femur of the ultimate legs (Figs 33, 37) with or without spines; pretarsus not shorter than corresponding tarsus 2 (in T. posticus (Say, 1821) longer than the two tarsal articles together), circular in cross section (i. e. not blade-like ventrally).

Number of species. 6 (Bonato et al. 2016). Remarks. Treated as a genus in Di et al. (2010: 51), Edgecombe & Bonato (2011: 395), Vahtera et al. (2012 a: 5), Bonato et al. (2017: 1). Edgecombe & Koch (2008: 894) described the pretarsus of maxillae 2 in both T. erythrocephalus (C. L. Koch, 1847) and T. posticus as “ two curved processes, one above the other ”. The most recent account on Theatops — Di et al. (2010) — contains no information on structure of maxillae 2. A re-studied adult (Rc 6489) of T. spinicaudus Wood, 1862 demonstrates not “ two curved processes ” but a pretarsus and a much shorter ventral projection (see also Diagnosis of Plutoniumidae above) whereas in two adults (Rc 6488, 6493) of T. posticus the ventral projection is nearly as long as the pretarsus.

This dataset contains the digitized treatments in Plazi based on the original journal article Schileyko, Arkady A., Vahtera, Varpu, Edgecombe, Gregory D. (2020): 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.
