Differential diagnosis
This species resembles Balta yaoi sp. n. in appearance, but can be distinguished from the latter by the following characters: 1) tegmen with more obvious black spots, cells slightly more hyaline and without yellowish brown spots (Fig. 31); while in the latter species, the tegmen has fewer and less obvious black spots, cell with yellowish brown spots; 2) median phallomere complex, the appendage base with brush-like structure (Fig. 38); while the latter with median phallomere simple, the appendage arched and without brush-like structure.
Description
Male. Body tawny. Face between eyes brown, between ocelli and antenna sockets with a light brown stripe, under antennal sockets also with a light brown stripe (Fig. 28). Pronotum with some small scattered and symmetrical spots or inconspicuous stripes, with tawny disk, lateral borders hyaline (Fig. 30). Tegmen and hind wing tawny, tegmen with black spots (most distributed on veins) (Fig. 31). The middle of anterior margin of abdominal tergites blackish brown. Third and fourth maxillary palpomeres approximately same length, both distinctly longer than the fifth (Fig. 29). Tegmen with M and CuA oblique (Fig. 31). CuA of hind wing with three complete branches and without incomplete ones (Fig. 32). Front femur of type C2 (Fig. 33), tarsal claws strongly asymmetrical and unspecialized (Fig. 34). Abdominal tergites unspecialized.
Male genitalia. Supra-anal plate short, hind margin rounded; right and left paraprocts similar (Fig. 35). Subgenital plate with hind margin strongly concaved; styli conical, arising on apexes of lateral lobes and slightly curved laterally (Fig. 36). Hook-like phallomere on the right side and with preapical concavity (Fig. 37). Median phallomere stick-like, curved near acuminated apex, median phallomere appendage present and with brush-like structure (Fig. 38). Left phallomere complex (Fig. 39).
Female. Supra-anal plate longer than subgenital plate, hind margin of the former with triangular process in the middle. Subgenital plate simple with hind margin rounded.
