Taxonomic assessment of Chirosiomima Hennig (Diptera: Anthomyiidae), with proposal of a new genus for Hylemyia curtigena Ringdahl.

The four nominal species currently included in the anthomyiid genus Chirosiomima Hennig, 1966 are critically assessed and redescribed. It is shown that the type species of Chirosiomima was originally misidentified. Chirosiomima obscurinervis (Emden, 1941) is resurrected from synonymy of C. gestroi (Séguy, 1930). Chirosiomima collini Ackland, 1968 is transferred to Botanophila Lioy (comb. nov.) and C. curtigena (Ringdahl, 1935) to Ringdahlia gen. nov. (comb. nov.). The previously unknown male of C. gestroi and female of R. curtigena (Ringdahl) are described.
