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. For diagnostic characters separating Henicopidae and Anopsobiidae , see Anopsobiidae , below.
