Shi, Fuming, 2017, New genus to science of Meconematinae (Orthoptera: Tettigoniidae) from China with description of two new species and proposal of one new combination, Zootaxa 4317 (1), pp. 165-173 : 165-166

Doicholobosa gen. nov.

Type species: Doicholobosa complanatis sp. nov., by herein designation.

Generic diagnosis. Body medium, stout. Fastigium verticis stout, conical, dorsal surface with a thin longitudinal furrow. Eyes nearly global, projecting forwards. Apical segments of maxillary palpi slightly longer than subapical ones, apices indistinctly inflated. Metazona of pronotum not elevated, posterior margin rounded; posterior margin of lateral lobe gradually narrowing, without humeral sinus. Tegmina short, hiding under pronotum, invisible in dorsal view; hind wings absent. Fore coxae with a spine. All femora unarmed on ventral surface, knee lobes of hind femora with apices rounded. Tympana of fore tibiae open on both sides, apices of hind tibiae with a pair of dorsal apical spurs and 2 pairs of ventral apical spurs. Posterior margin of male tenth abdominal tergite with median angle-shaped concavity, lobes spine-shaped; cerci straight, simple, without any processes; genitalia sclerotized; subgenital plate long, posterior margin with a big U-shaped concavity, lateral lobes long and curved upwards on both sides; without styli. Posterior margin of female tenth abdominal tergite with 2 short spine-shaped processes, slightly concave between them; ovipositor stout, dorsal and ventral margins smooth, apices acute.

Species included. The genus is endemic to China, including 2 new species and a new combination totally.

Discussion. The new genus differs from other genera of Meconematini by: posterior margin of male tenth abdominal tergite with a pair of long spine-shaped processes, between them triangular concave; dorsal surface of male genitalia with a long process, ventral surface broad, with many small teeth; posterior margin of subgenital plate with 2 long lateral lobes, obviously curved dorsally, without styli; posterior margin of female tenth abdominal tergite with a pair of apical processes, slightly concave between them.

Etymology. The generic name refers the long lateral lobe of male subgenital plate on posterior margin.
