Incolacris C. Willemse, 1932: 150 (type species: Incolacris rubritarsi C. Willemse, 1932, by original designation); C. Willemse, 1939: 89; Tinkham, 1940: 302; C. Willemse, 1956: 185.

Description. Head in frontal view elongated; frontal ridge broad, complete, almost reaching clypeus (Fig. 5). Face in lateral view reclinated; frontal ridge almost straight (Figs. 4, 8). Ventral genicular lobes of the hind femora triangular with distinct apical spine (Fig. 12). Male 10th abdominal tergite without furculae (Fig. 10). Male supra-anal plate triangular, with a median basal impression, lateral margins with two teeth in the basal half on each side or without it. Male cerci surpassing the supra-anal plate, compressed, conical, with pointed apex, without teeth on the inner side (Fig. 11). Valves of ovipositor short, with apex rounded and strongly dentate (Fig. 6). Male genitalia: epiphallus with broad bridge, ancorae present (Fig. 15); the shape of other parts of genitalia unknown.

Species included. The genus consists of five species distributed in the Philippines, South China and Malaysia.

Remarks. Hollis (1975) synonymized Incolacris under Stolzia based the only on the asymmetrical shape of epiphallus but I disagree with such synonymy and consider it as a distinct genus differs from other genera of Incolacridinae in the specific shape of frontal ridge.
