Gryllidae : Trigonidiinae Svistella Gorochov, 1987

Svistella Gorochov, 1987: 13

Type species. — Svistella bifasciata ( Shiraki, 1911)

Diagnosis. — Svistella is characterised by the presence of both tympana on fore tibiae; strongly and characteristically notched hind edge of pseudepiphallus, hind pseudepiphallic lobes with long and narrow apical processes, median part of pseudepiphallus narrow and arcuate, guiding rod long, endophallus includes three sclerites (median one with apodeme, and a pair of lateral ones with transverse narrow ribbons directed aside), pseudepiphallic parameres not completely separated from pseudepiphallus (A. V. Gorochov, in litt.).

Discussion. — Trigonidiinae is in need of revision and genitalia of Indo-Malayan species are insufficiently studied. It is thus difficult to ascertain new species until all known species are examined and revised. The genus Svistella was erected by Gorochov (1987) and six species were described since then ( He et al., 2009; Eades et al., 2012). More species may be added to this genus. Although only a few species of Svistella are hitherto described, we suspect that this genus is diverse in South East Asia, with some species having restricted distribution. These render us the description of the new species from mangroves.
