Callibaetis gregarius Navás

Callibaetis gregarius Navás, 1930a ; Gillies, 1990; Domínguez et al., 2006, p. 113.

Known stages: I ♂

Diagnosis

Male imago. (1) Forewing hyaline; (2) hind wing with pointed costal process (fig. 16 in Navás 1930a); (3) abdominal terga with two longitudinal marks.

Comments

In the original description only the hind wing is illustrated. The type series was at the Zoological Museum of Berlin, and one specimen, in poor condition, is deposited in the Zoological Museum of Barcelona ( Gillies 1990). Gillies (1990) examined the specimen from Barcelona and reported that it would be necessary to examine more specimens to clarify the status of this taxon.

Material examined

No types or specimens were examined; diagnosis was based on the literature.

Distribution

Brazil: São Paulo state, Ipiranga county.
