Bittacus striatus Issiki, 1927
Diagnosis: This species has wings with dark shading along gradate series and at the origin of radial sector and branches of cubital vein. The male epiandrial lobes are about the same size as the basistyles and the base of the aedeagus is gradually widened until abruptly constricted to narrow stalk.
Distribution – Geographical: This species is known from Kobayashi, Rato (=Kobayash =Hsiaolin = Hsiaolin, Jiaxian Township, Kaohsiung County, 23.1724°N, 120.654°E), 29 July 1923, Professor T. Shiraki, 1♂ (TARI); Taipin (=Taping City, Taichung County, 24°07’08.15”N, 120°46’53.27”E), 23 July 1918, J. Sonan, 1♀ (TARI).
Distribution – Temporal: The two known collections of this species are from mid-summer in July.
Ecology: This species is found at relatively low elevations in west-central Taiwan.
Biology: Nothing is known of immature stages or life history.
Notes: This species appears to be quite closely related to Bittacus maculatus, but can be separated from that species by the more tapered base of the aedeagus and the elongate band that goes through the first fork of the anterior cubitus (CuA) of the hindwing of B. striatus.
