50. Isostomyia Coquillett, 1906e: 16 , 24.

ORIGINALLY INCLUDED SPECIES: Aedes perturbans Williston, 1896 ; Aedes nigricorpus Theobald, 1901 .

TYPE SPECIES: Aedes perturbans Williston, 1896 , by subsequent designation ( Coquillett 1910c: 556).

CURRENT STATUS: Valid genus [ teste Guimarães (1997: 104) ].

FAMILY: CULICIDAE .

REMARKS: Howard et al. (1915: 186) stated that the type species of Isostomyia Coquillett, 1906e was Aedes perturbans Williston, 1896 by original designation. Guimarães (1997: 104) and Knight & Stone (1977: 312) stated the same type species but by monotypy. A check of Coquillett (1906e) shows that no type designation was made in that work. Although Coquillett (1910c: 556) indicated that Aedes perturbans Williston, 1896 was the only species in this genus, the questionable inclusion of Aedes nigricorpus Theobald, 1901 by Coquillett (1906e: 24) qualifies as an originally included species according to ICZN Code Art. 67.2.5. Thus, a subsequent designation from the two originally included species is needed. The earliest valid subsequent type designation I have found in this study is that by Coquillett (1910c: 556).
