Description

See description Table 2 and Fig. 1i, Fig. 2g, Fig. 3i, Fig. 5c.

Diagnosis

Male. In the keys of Borgmeier (1964), this species can be taken through either the group III or group V key, depending on whether one takes the stronger setae on the posterior edge of the anepisternum as strong hairs or weak bristles. In the key to group III, it keys to couplets 13 or 14 (depending on whether the setation on the epandrium is judged to be bristles or bristlelike hairs), and in the key to group V it keys to couplets 6 or 7 (depending on whether the brown palps are considered to be black or yellow). It can easily be differentiated from any of the species found at these couplets by the presence of dense fields of short, blunt spines on f3 basally (Fig. 2g).
