Genus Aneuroderma Xiong, Engel & Ren gen. nov.

Diagnosis.

Moderate-sized earwigs, with numerous setose and distinctively sculptured (densely punctate-granulose throughout, particularly on head and thorax). Head broad, nearly as wide as anterior border of pronotum, posterior margin nearly straight. Antenna with 20 antennomeres; scape robust and slightly broader than remaining antennomeres; pedicel slightly longer than wide; all flagellomeres longer than wide. Compound eyes large and situated at posterior temples; ocelli absent. Dorsal surface without Y-shaped ecdysial cleavage scar. Pronotum approximately oval, anterior and posterior margins subequal in width, lateral margin convex and rounded. Tegmina without longitudinal veins; tegmina and squamata covering abdominal segment II. Legs with abundant short setae; femora carinulate; all tarsi pentamerous (i.e., tarsal formula 5-5-5 rather than the 4-4-5 of some genera); pretarsal claws simple. Female with exposed ovipositor. Pygidium small. Cerci filiform and long, with about 30 cercomeres.

Etymology.

The generic name is a combination of the Greek prefix a - (ᾰ -, alpha privativum designating negation), neûron (νεῦρον, meaning, “nerve”), and dérma (δέρμᾰ, genitive dérmatos, meaning, “skin” - an allusion to the leathery tegmina and from which the ordinal name is derived, Dermaptera literally meaning, "skin wings"), referencing the absence of tegminal venation, a rare feature among Archidermaptera . The gender of the name is neuter.
