Phortica saltiaristula Chen and Wen View in CoL , sp. nov.

( Figure 3 View Figure 3 )

Diagnosis

Tip of arista broadened ( Figure 3A View Figure 3 ); right lateral lobe of vertical process of gonopod with one pointed projection basally ( Figure 3C View Figure 3 ); paramere strongly curved distally ( Figure 3C, D View Figure 3 ).

Some characters commonly seen also in P. sagittaristula sp. nov. are not referred to in the following description.

Description

Distribution

China (Yunnan).

Relationships

This species is very similar to P. sagittaristula sp. nov. in having the arista without dorsal branches, and in the shape of the gonopod, but differs from the latter species by their diagnostic characters.
