http://lsid.speciesfile.org/urn:lsid: Orthoptera .speciesfile.org:TaxonName:514183
Diagnosis. Eyes not reduced (as wide as half of the scapus) and normally pigmented ( Fig. 13A, B View FIGURE 13 ). Pronotum subquadrate, slightly broader than long, anterior and posterior margins almost straight, lateral margins broadly convex, wider anteriorly than at the mid-length, lower parts of lateral lobes only moderately flared ( Fig. 13C View FIGURE 13 , 14A View FIGURE 14 ).Apterous species. Legs relatively short and stout, hind tibia with four dorsal spurs on each margin; all tarsi slender and elongated, first tarsomere armed dorsally and as long as a third of its respective tibiae. Abdominal tergites unspecialized without glandular apparatus; male epiproctus rectangular or subtriangular, wider than long. Cerci slender and almost as long as the hind femur. Females unknown. Male genitalia compact and covered by a membrane; ectophallic fold moderately sclerotized and poorly developed; pseudepiphallic median lophi with or without a medial notch and on the posterior lateral borders rounded and covered by several denticulations on the posterior portion; pseudepiphallic paramere rounded and without additional projections; endophallic apodeme slim, membranous and connected to the sclerotized endophallic sclerite; ectophallic apodeme slim, curved in lateral view and parallel; rami notoriously expanded dorsally ( Fig. 13 View FIGURE 13 D-F, 14C-E).
Etymology. Dedicated to Crystian Sadiel Venegas Barrera, in recognition of his excellent and inspiring research and teaching work at the Tecnologico Nacional de Mexico (Victoria campus), as well as thanks for all his support for the first author during his stay in Mexico. With the ending - cophus , referring to its closeness to that genus. Gender is designated as neutral.
Taxa included: Venegascophus reddelli ( Hubbell, 1972) n. comb. (Type species) and V. sanctorum ( Hubbell, 1972) n. comb.
Comments. This new genus is partially derived from the first group proposed by Hubbell (1972) “GROUP I. Epigeic and troglophilous species with relatively short legs and normally pigmented eyes”, including two very similar species in external morphology and peculiar genitalia, in contrast to the other Paracophus s.l. species.
Key to Venegascophus n. gen. species
1. Male epiproctus rectangular. Pseudepiphallic median lophi broad, divided and expanded into two rounded lateral lobes. Pseudepiphallic lateral lophi, narrow, and subtriangular in lateral view ( Fig. 13 View FIGURE 13 , D-F)....................... V. reddelli n. comb.
– Male epiproctus subtriangular. Pseudepiphallic median lophi mid-size, divided by a small notch, with two sub-triangular lateral lobes. Pseudepiphallic lateral lophdi, broad, and rounded in lateral view ( Fig. 14 View FIGURE 14 C-E).............. V. sanctorum n. comb.
