Additional material. Tasmania: 233, Ridgeway, 3.ix.1916, C.E Cole (MVM). Victoria: 233, Bayswater, iv.1928, 1♀, Ferntree Gully, 15.iv.1928, 233, Ringwood, iv. 1928 (all F.E. Wilson, MVM).

Description. Male length 3.6–3.7; wing: 3.8. Head frons, postcranium face mostly black with grey pruinosity, but darker around ocellar triangle; face bare of setae. Thorax mostly dark brown with brownish pruinosity dorsally and greyish pruinosity on pleura, but no distinct patterns present; ac biseriate and extending to posterior slope of mesonotum. Legs CI yellow but infuscated basally; CII and CIII mostly brownish but distally yellow, and with grey pruinosity; femora and tibiae mostly yellow, but appearing darker and brownish in some specimens; tarsi dark brown; vestiture pale yellow except where noted; I 3.7; 3.3; 2.1/ 0.5/ 0.4/ 0.3/ 0.4; TI ( Fig. 1d) with 3 black dorsal setae at 2 ⁄ 5, 3 ⁄ 5, and 7 ⁄ 8, which distally increase in size, with distalmost seta 2 ⁄ 3 length of TI (MSSC); It 1 greatly swollen, and with some short dorsoapical setae (MSSC); II: 4.0; 4.3; 1.3/ 0.4/ 0.3/ 0.2/ 0.5; TII with outstanding dorsal setae at 3 ⁄ 4 and 7 ⁄ 8 (MSSC); IIt 1 setose; III 5.2; 5.0; 1.8/ 0.7/ 0.4/ 0.3/ 0.5; FIII with some long dorsal and av setae. Wing ( Fig. 1e) membrane slightly smoky; halter yellowish with distinctly brown club. Abdomen almost entirely dark brown with yellow to brownish setae; setae on tergum I and posterior margins of remaining terga relatively long; male postabdomen ( Fig. 1f); median basal projection of hypandrium broadly triangular.

Female: similar except as noted. femora with only short pale ventral setae; TI and TII without strong dorsal setae; It 1 unmodified; TIII only weakly flattened laterally.

Remarks. Eugowra colei is readily distinguished from congeners by the three strong dorsal setae on tibia I. This species is known from Tasmania and southern Victoria. All specimens were collected in cool months, from April to October, and mating pairs were captured during July in Hobart. This species is named for C.E. Cole, whose extensive collections of Tasmanian Diptera are deposited at the Museum of Victoria.
