The centipede family Anopsobiidae new to North America, with the description of a new genus and species and notes on the Henicopidae of North America and the Anopsobiidae of the Northern Hemisphere (Chilopoda, Lithobiomorpha) Author Shear, William A. text Zootaxa 2018 4422 2 259 283 journal article 29146 10.11646/zootaxa.4422.2.6 47816d99-6645-43ad-a52d-33cc68a6a7c7 1175-5326 1455619 F6658C2B-9681-430A-8975-7B3AE2C233EE Family Henicopidae Pocock, 1901 The family Henicopidae is distinguished from Lithobiidae , the other currently widely recognized family of Lithobiomorpha , except Anopsobiidae , by the absence of spurs at the distal ends of most of the podomeres (present in Lithobiidae ) and the presence of a distal, acute triangular spine on the tibiae of at least the first 11 pairs of legs (absent in Lithobiidae ). The male gonopods of henicopids have 3 or 4 articles and end in a long filament, whereas in lithobiids the male gonopods are blunt and 1- or 2-articled.
