Cadena-Castañeda, Oscar J., 2019, A proposal towards classification of the Raspy Crickets (Orthoptera: Stenopelmatoidea: Gryllacrididae) with zoogeographical comments: An initial contribution to the higher classification of the Gryllacridines, Zootaxa 4605 (1), pp. 1-100 : 34

Hugelgryllacris n. gen.

Diagnosis: Medium sized (24 mm for only known species) and body robust ( Fig. 140 ). Head globose and prominent ( Fig. 141 ), wider than pronotum, ocelli inconspicuous, fore coxa with a little developed spine; legs moderately short and robust, with four pairs of short movable ventral spines (excluding the two little apical spines) on fore and mid-tibiae, hind femora armed with medium sized spines from the middle to apex ventrally ( Fig. 142 ); wings well developed, covering the last abdominal tergites; M vein born near the R basal section (variation of the IV type venation) ( Fig. 143 ). Penultimate sternite bearing a process on the anterior margin of the sternite, directed backwards; longer than the subgenital plate; ovipositor as long as the hind femur, smooth and with rounded tip ( Figs. 144, 145 ).

Type species: Hugelgryllacris tchancha (Hugel, 2009) n. comb.

Etymology: Dedicated to Slvain Hugel as a recognition to his contributions to Orthoptera fauna from Insular region from Indian, Atlantic and Pacific oceans, plus typical termination— gryllacris common to genera of this family.

Comparision: This new genera, known so far only by females, has the typical characters of the taxa grouped in the tribe Eremini. It differs from the genera of that tribe in being the only macropterous one known so far; besides, known females of other Eremini genera lack the modification of the sternite previous to the subgenital plate. Of the tribe genera; Hugelgryllacris n. gen., resembles more Kinemania in shape and number of spines of the fore and mid-tibiae, likewise with the ovipositor structure; though in Kinemania it is a bit longer.

Distribution: Vanuatu, Southwestern Pacific.
