Variation Male (n = 10). Body length 2.2–3.6 mm, mean 2.7 mm; wing length 1.5–2.1 mm, mean 1.8 mm; wing width 0.3–0.5 mm, mean 0.4 mm.

Geographical record. Brazil (Maranhão).

Remarks. Hemerodromia joanae sp. nov. appears to belong to the same group of species that includes H. joseaugustoi sp. nov., H. lamellata Câmara, Plant & Rafael, 2014 , H. longilamellata Câmara, Plant & Rafael, 2014 , H. megalamellata Câmara, Takiya, Plant & Rafael, 2015 and H. membranosa Câmara, Takiya, Plant & Rafael, 2015 in having membranous area long or nearly as long as tergite 8 between segment 8 and terminalia, and long gonocoxal and ejaculatory apodemes. Hemerodromia joanae sp. nov. is similar to H. lamellata in having the cercus wider basally, bluntly narrower distally with pointed apex, curved up distally. Hemerodromia joanae sp. nov. differs from H. lamellata by having tergite 8 brown (tergite 8 yellow in H. lamellata ) and subepandrial sclerite with subrounded anterior projection (subepandrial sclerite with short triangular anterior projection in H. lamellata ).

Comments. Specimens of H. joanae sp. nov. were collected in Cândido Mendes from January to July and in Centro Novo do Maranhão from December to February.
