Family Scolopocryptopidae Pocock, 1896

Diagnosis. Eyes absent. Labrum with a single median tooth ( Fig. 23 ); maxillae 2 with pectinate pretarsus ( Figs 10, 13 , 16 , 24 ) which consists of two well-distinguishable parts (darker basal and a semi-transparent apical ones, see fig. 2 in Schileyko 2018) but is not accompanied by any projections or accessory spine(s). Forcipular coxosternite with chitinised anterior margin ( Figs 8 , 21 ), rarely with short projections ( Figs 9 , 22 ) but never with prominent toothplates. Forcipular trochantero-prefemur with or without process. Sternites usually with variably expressed median longitudinal sulcus/suture, and rarely (in Kethopinae Shelley, 2002 ) with a transverse suture(s). Coxopleuron with or without process. 23 LBS; spiracles on macrosegments (7 th LBS with or without them), spiracles open, lacking flaps ( Fig. 25 , fig. 5A in Vahtera et al.) 2012b. Ultimate LBS considerably shorter than the penultimate one. Ultimate legs of four types (see below the subfamilial diagnoses). Tarsi of locomotory legs with two articles; legs with or without 1 or 2 tibial spurs and 1 tarsal spur. Ultimate leg prefemur with spinous processes. Edgecombe & Bonato (2011) also wrote: “Gizzard with stiff, pineapple-shaped, projections; main zone of projections having a kink near their midlength”.

Number of subtaxa. 3 subfamilies, 4 genera.

Range. Caribbean Islands, Cocos Island, North, Central and South America; W Africa; China, Japan, Korea, Vietnam, Philippines, Sunda Archipelago, New Guinea, Fiji.

Remarks. Treated as a family in Edgecombe & Bonato (2011: 403), Vahtera et al. (2012a: 4), Vahtera et al. (2012b: 232), Edgecombe et al. (2012: 768).
