An overview of the extant genera and subgenera of the order Scolopendromorpha (Chilopoda): a new identification key and updated diagnoses Author Schileyko, Arkady A. schileyko1965@gmail.com Author Vahtera, Varpu varpu.vahtera@gmail.com Author Edgecombe, Gregory D. 0000-0002-9591-8011 schileyko1965@gmail.com text Zootaxa 2020 2020-08-10 4825 1 1 64 journal article 8703 10.11646/zootaxa.4825.1.1 5ab5f5c8-481e-4d1a-8643-21e72c367278 1175-5326 4402145 F230F199-1C94-4E2E-9CE4-5F56212C015F Tribe Otostigmini Kraepelin, 1903 Synonyms. Arrhabdotini Attems, 1930 Diagnosis. Antenna relatively long (i.e. reaching at least to posterior margin of tergite 4 when reflexed), basal antennal articles cylindrical (not strongly flattened), definitely longer than wide. Median tooth of labrum ( Fig. 95 ) well developed (except for Edentistoma , former tribe Arrhabdotini ; see below). Forcipular tooth-plates present (except for Edentistoma ), their basal sutures form a virtually straight line ( Fig. 96 ), right angle ( Fig. 91 ) or an obtuse angle ( Fig. 86 , 100 , 106 ); trochantero-prefemoral process present in most genera. Tarsungula long in most of genera ( Fig. 96 ), much elongated in Edentistoma and visibly shortened in Sterropristes (compare Fig. 114 and Fig. 120); their inner surface rounded or with 1 or 2 sharp longitudinal ridges, rarely saw-like (in Sterropristes only). LBS 7 with or without spiracles. Pleuron ( Figs 82 , 103 ) with intersclerite membrane well visible, without set of longitudinal pleurites anteriorly. Coxopleuron with ( Fig. 104, 105 ) or without (in Otostigmus ( Parotostigmus ) ( Fig. 99 ) and Alipes ) well-developed process. Ultimate leg pretarsus claw-shaped, well-developed in most genera. Edgecombe & Bonato (2011: 400) also wrote: “ Border between labral and clypeal part of epipharynx strongly curved forwards... Testicular vesicles oriented oblique to central deferens duct”. Number of subtaxa. 6 genera (3 subgenera in genus Otostigmus ). “Ca 200 species in six genera” sensu Edgecombe & Bonato (2011: 400) . Range. As for family. Sexual dimorphism. Present in 3 taxa of genus-group. Remarks. Treated as a tribe in Edgecombe & Bonato (2011: 400) , Vahtera et al. (2012a: 7 , 2012b: 235 ), Vahtera et al. (2013: 578) , Vahtera & Edgecombe (2014: 2 , 5, 7). In 2013 Vahtera et al. wrote (p. 578): “The generic classification of Otostigmini has a poor fit to phylogenetic relationships, although nodal support within this tribe is weak”.
