Zootaxa, 4605(1): 78.

Type species: Larnaca (Larnaca) fasciata Walker, 1869 .

Diagnosis. Body moderate, robust, black to dark brown. Frons smooth or with inconspicuous spots; fastigium verticis wider than scape. Tegmina reduced, at least longer than 2.0 mm, usually much longer than pronotum but not reaching apices of hind femora, black or yellowish brown, veins reduced, blackish or darker than the cells. Hind wings reduced or absent, hyaline or a little smoky. Male ninth abdominal tergite obviously projecting backwards, with 1 pair of heavily sclerotized crossed hooks; bases of hooks with movable rounded convexities, apex acute; cerci long. Subgenital plate broad, subapical area with normal and clearly developed styli. Female copulatory depressions situated on the apical area of seventh abdominal sternite. Apical area of subgenital plate not curved forward and downward.

Species included. Up to now, the genus included twenty two species. The most are recorded from Indonesia (Sumatra and Java) and Malaysia, and two of which are distributed in Southwestern China.

Discussion. Based on specimens from Thailand, Sumatra, Vietnam and Malaysia, Gorochov (2003) thought the generic species is without femoral-abdominal stridulatory complex, but we examined one Malaysian specimen from Malaysia and found the tegmina and ninth abdominal tergite is very similar to the other species of Larnaca except the presence of stridulatory area on second and third abdominal tergites.
