Diagnosis

The genus is characterized and separated from all other Parahiraciini genera by the following combination of characters:

(1) head with vertex apparently elongate, about 1.1 times as wide as long in midline, not projecting anteriorly and with hind margin angularly excavate;

(2) frons more or less flattened, with a median carina, with a row of tubercles along lateral margins and with upper margin concave;

(4) body oval in dorsal aspect, less than twice as long as maximum width;

(5) metatibiae with two to five lateral and eight apical spines;

(6) tegmina with vein CuA curved at apex of clavus, unbranched and reaching the hind margin of tegmen;

(7) anal tube of male dorsoventrally flattened, rather wide;

(8) gonostyli with capitulum rather massive and projecting dorsad, with a moderate neck;

(9) aedeagus evenly and moderately curved in lateral view, with pair of elongate, usually slender, symmetrical, lateroventral processes.

Note

Only one species of Flavina was recorded from Vietnam, F. acuta , described by Ran & Liang (2006) based on a male holotype from Laos, Vientiane Province, Ban Van Eue and two male paratypes from Vietnam, Lam Dong Province: Dalat and Mount Langbian, respectively. It is interesting to note that the locality of the holotype is separated by more than 1000 km from those of the paratypes. Another record of the genus Flavina , based on a single female from Lam Dong Province, Bidoup massif, was provided by Gnezdilov et al. (2014a).
