Treatment

Phortica glabtabula Chen and Gao View in CoL , sp. nov.

( Figure 6 View Figure 6 )

Diagnosis

Secondary process of paramere small, with one sensillum subapically ( Figure 6C View Figure 6 ); branch of aedeagal basal bridge sclerotized along outer margin, with about seven acute, marginal projections ( Figure 6C View Figure 6 ).

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

Description

Head. Frons brown, pale lower. Face, gena and postgena brown.

Thorax. Anepisternum lacking setulae.

Legs. Yellow except femora mostly brown.

Abdomen. Second tergite laterally with brown-black patches; third and fifth with medially protruded and sublaterally interrupted, broad, brown-black bands along posterior margins; sixth nearly entirely black.

Male terminalia. Epandrium with pubescence anteroventrally, and 11–12 setae near posterior margin ( Figure 6A View Figure 6 ). Surstylus with pubescence, and dense setae, and about 20 apically round prensisetae ( Figure 6A View Figure 6 ). Vertical process of gonopod very large, narrowed and sclerotized apically ( Figure 6C View Figure 6 ). Paramere distally pubescent, with one sensillum and two teeth apically ( Figure 6C View Figure 6 ). Aedeagal median rod slender ( Figure 6C View Figure 6 ).

Measurements. BL 53.30 mm; ThL 51.37 mm; WL53.00 mm; WW 51.20 mm.

Remarks

This species resembles P. cardua in having the anepisternum lacking setulae, and the shape of the paramere and gonopod, but can be distinguished from the latter species by the arista and the vertical processes of the gonopod ( P. cardua has only one short ventral branch in the arista; vertical process of gonopod depressed and unsclerotized medially).
