E. formosana (Hennig, 1936) , comb. n. ( fig. 1 )

Apyrgota formosana Hennig, 1936: 253 ; Steyskal, 1977: 39.

M a t e r i a l. Type. Holotype ♀: “ West-Formosa, Kagi ”, 12.06.1907 (H. Sauter leg.) (not located; specimen was deposited in ZMSH, destroyed in the WWII). Non-type. Taiwan: Kaohsiung, Shanping , 640 m, 1– 10.05.1988, 1 ♀ ( R. Davidson, C. Young, J. Rowlins) ( CMNH) .

D i a g n o s i s. This species can be recognized from the combination of concave face without facial carina; one pair of long ocellar setae; parafacial in profile half as wide as flagellomere 1, mesonotum and abdomen with brown pattern; scutellum with two pairs of long setae (basal short); wing hyaline, grey microtrichose in anterior half, yellow cell r1, and brown radial fork and spot at apex of R 2+3 and spurious vein; all femora without strong dorsal setae, with basal ventral, 2 long posteroventral setae near middle and two rows of moderately strong, spurious apicoventral setae; fore femur with 2–3 long subbasal ventral (in addition to common basal), mid femur without strong anterior setae and femoral organ; abdominal sternites moderately long and densely setulose; oviscape geniculate, its narrow apical half bent ventrally; ventral hooks on oviscape slender.

R e m a r k s. The presence of narrow parafacial, long antenna and slender hooks of oviscape along with the lack of facial carina, support its placement to Taeniomastix . Steyskal (1977) erroneously dated Apyrgota formosana Hennig as “1938”, but actually the journal, where article was published, is dated from 1936.
