Ocyptamus callidus species group. Miranda et al. (2016).

Diagnosis. Dorsal occiput with two rows of pile. Alula narrow. Abdominal terga with ‘L’-shaped yellow markings. Male abdominal sternum 4 asymmetrical, with right side projected and acute.

Comments. Superficially similar to the O. lepidus species group, but these species have distinct ‘L’-shaped markings on the abdomen, two rows of pile on the dorsal occiput and strikingly different genitalia.

Species list (2): O. callidus ( Hine, 1914) , O. pumilus ( Austen, 1893) .
