Subfamily Scolopocryptopinae Pocock, 1896

Diagnosis. Antenna densely covered with collared sensilla apart from a few basal articles. Anterior margin of forcipular coxosternite sclerotized ( Fig. 8 ), sometimes with small processes ( Fig. 9 ), but never with well-developed tooth plates. Forcipular trochantero-prefemur with well-developed, simple (i.e. not furnished with additional tubercles) process ( Figs 8, 9 ). LBS 7 usually with spiracles (or without them in the former Dinocryptops ). Coxopleuron with conical process. Ultimate legs of “common” shape (sensu Schileyko 2009) i.e. the most similar to the locomotory ones ( Fig. 7 )—elongated, relatively slender and not transformed; ultimate prefemur with a single strong ventral and smaller dorsomedial spinous processes (the latter virtually absent in Scolopocryptops gracilis Wood, 1862 only), femur without those processes, pretarsus claw-shaped.

Number of subtaxa. 1 genus.

Sexual dimorphism. Unknown.

Range. Temperate and tropical regions of North America, Central and South America, Caribbean Islands; W Africa; China, Japan, Korea, Vietnam, Philippines, Sunda Archipelago, New Guinea, Fiji.

Remarks. Treated as a subfamily in Edgecombe & Bonato (2011: 403), Vahtera et al. (2012a: 9), Vahtera et al. (2012b: 232), Edgecombe et al. (2012: 7687).

Figs 7–10

Synonyms. Otocryptops Haase, 1887 ; Anethops Chamberlin, 1902 ; Dinocryptops Crabill, 1953 .

Type species. Scolopocryptops melanostoma Newport, 1845 (by subsequent designation by Lucas, 1849) .

Diagnosis. As for subfamily.

Number of species. 25 (new data), 22 ( Edgecombe & Bonato 2011: 403), 24 ( Bonato et al. 2016).

Remarks. Treated as a genus in Edgecombe & Bonato (2011: 403), Vahtera et al. (2012a: 7), Vahtera et al. (2012b: 232), Edgecombe et al. (2012: 768), Bonato et al. (2016). The most recent morphological accounts on Scolopocryptops are those of Edgecombe et al. (2012) and Chagas-Jr & Bichuette (2015).

The closely related genus Dinocryptops Crabill, 1953 (present in Edgecombe & Bonato 2011: 404) was formally placed in subjective synonymy under Scolopocryptops by Edgecombe et al. (2012: 777): “… morphology-based analyses suggest that recognition of Dinocryptops leaves Scolopocryptops as a paraphyletic grouping ... The phylogenetic analyses described below strongly support the paraphyly of Scolopocryptops with respect to Dinocryptops , using morphological, molecular or combined data and we have accordingly placed Dinocryptops in subjective synonymy of Scolopocryptops ”.
