this genus. In addition, the discovery of a lamella on the movable finger of the chelicera, not reported by Rowland and Reddell (1981), and the constriction of the posterior part of the the male pygidial flagellum, present in all known species of Heteroschizomus (and some species of Piaroa ), confirms the monophyly of the genus and justifies its revalidation. The elongated opisthosoma observed in Heteroschizomus appears to have evolved convergently in other schizomid genera, e.g., Hansenochrus , Hubbardia , and Piaroa .
Stenochrus meambar Armas and Víquez, 2010 was assigned to Heteroschizomus based on the presence of a lamella on the cheliceral movable finger and a lanceolate pygidial flagellum, with a medial constriction and a dorsomedian depression, in the male (Armas and Víquez, 2010). The unnamed genus from Honduras described in the same publication (Armas and Víquez, 2010: 18) is probably also a female of Heteroschizomus , because the spermathecae are very similar, with a mug-shaped chitinized arch, and the two pairs of short lobes, similar in length.
