description
Number of subtaxa. 6 genera (3 subgenera in genus Otostigmus). “ Ca 200 species in six genera ” sensu Edgecombe & Bonato (2011: 400).
description
Sexual dimorphism. Present in 3 taxa of genus-group.
diagnosis
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 ”.
discussion
Remarks. Treated as a tribe in Edgecombe & Bonato (2011: 400), Vahtera et al. (2012 a: 7, 2012 b: 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 ”.
