Subfamily Otostigminae Kraepelin, 1903

Diagnosis. Anterior margin of forcipular coxosternite ( Figs 86 View FIGURES 84–88 , 96 View FIGURES 89–96 , 100 View FIGURES 97–101 , 111 View FIGURES 108–112 ) with tooth-plates (except for Edentistoma , Fig. 114 View FIGURES 113–118 ); forcipular trochantero-prefemur in most genera with well-developed process (the latter virtually absent in Ethmostigmus ( Fig. 102 View FIGURES 102–107 ), Edentistoma and Sterropristini Verhoeff, 1937 ). Tergites with ( Fig. 87 View FIGURES 84–88 ) or without longitudinal keels. Sternites with paramedian sutures developed to varying degrees (totally absent in Edentistoma ) and in most both genera and species with a few (from 1 to 5) depressions of varied size and shape (rounded and/or longitudinal). LBS 7 with or without spiracles. The spiracles oval or round, of open type (i.e. without any covering “flap”), in most genera with well-developed atrium ( Figs 82 View FIGURES 78–83 , 108 View FIGURES 108–112 ), sometimes exceptionally shallow, for example in Ethmostigmus ( Fig. 103 View FIGURES 102–107 ) and Edentistoma ( Fig. 115 View FIGURES 113–118 ); the atrial floor raised in humps ( Fig. 108 View FIGURES 108–112 ). Legs with 1 or 2 tarsal spur(s), sometimes with 1 tibial spur as well. Ultimate legs of “common” shape ( Figs 83 View FIGURES 78–83 , 101 View FIGURES 97–101 , 110 View FIGURES 108–112 ) in most genera of Otostigmini (except for “leaf-shaped” ones in Alipes Imhoff, 1854 ( Fig. 84 View FIGURES 84–88 ) and quasi “pincer-shaped” in Edentistoma ) and truly “pincer-shaped” in Sterropristini (Fig. 119). Ultimate prefemur with ( Figs 83 View FIGURES 78–83 , 101 View FIGURES 97–101 ) or without (in Otostigmus (Parotostigmus) Pocock, 1896 ( Fig. 97 View FIGURES 97–101 ), Alipes, Edentistioma and Sterropristes ) some spines and with or without corner spine. Claw-shaped ultimate pretarsus ( Fig. 101 View FIGURES 97–101 ) present (virtually absent in Alipes only, Fig. 85 View FIGURES 84–88 ); when pretarsus strongly elongated and enlarged (Fig. 119) it usually lacks accessory spines. Vahtera & Edgecombe (2014) also wrote: “lateral clusters of sensilla on the clypeal part of the epipharynx.”

Number of subtaxa. 8 genera (10 taxa of genus-group). “Ca 200 species in nine genera” sensu Edgecombe & Bonato (2011: 400), “115 valid species” sensu Vahtera & Edgecombe (2014: 7).

Sexual dimorphism. Present in 5 taxa of genus-group.

Range. From the Canary Islands through all Africa (and neighboring islands) and southern half of Asia to Australia, New Guinea, New Zealand and Pacific Islands (incl. Bismarck Archipelago, Solomon Islands, Polynesia); Neotropics including Caribbean.

Remarks. Treated as a subfamily in Edgecombe & Bonato (2011: 400), Vahtera et al. (2012a: 13), Vahtera et al. (2012b: 235), Vahtera & Edgecombe (2014: 7).
