Bittacus formosanus  Issiki, 1927

Diagnosis:  Heavy infuscation at origin of radial sector (Rs), first fork of radial sector, and along most crossveins. Wing tip not shaded.   Apical crossvein between Cu and 1A absent.  Male epiandrial lobes longer than basistyles and evenly rounded at apex.


Distribution – Geographical:  This species was originally described from four localities in Taiwan:  Taipin (=Taping City, Taichung County, 24°07’08.15”N, 120°46’53.27”E), Kobayashi (= Hsiaolin, Jiaxian, Kaohsiung County, 23.1724°N, 120.6544°E);  Suiriko (= Shueili, Shueili Township, Nantou County, 23°47’31.76”N, 120°51’41.33”E), and Rengechi (= Lienhuachih Forest Research Centre, Yuchin Township, Nantou County, 23°55’30”N, 120°53’24”E).  Byers (2002) records this species from Taipei County, Shintsu, 10 km northeast of San Min, 100 m, 10 April 1998, R.B. Miller, L.A. Stange, and H.-Y. Wang (FSCA).  It is endemic to Taiwan.


Distribution – Temporal:  Known records are from 10 April 1998, 23 July 1918, 28 August 1923, 6 August 1925, and 11 October 1926.  Thus, most adult emergence appears to occur in late summer.


Ecology:  This species appears to be found in lowland forested situations at elevations of about 100 to 800 m.


Biology:  Nothing is known of immature stages or life history.
