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

( Figure 5 View Figure 5 )

Diagnosis

Aedeagal median rod with one small, triangular process submedially ( Figure 5C View Figure 5 ); branch of aedeagal basal bridge bifurcated apically ( Figure 5C View Figure 5 ); vertical process of gonopod with six to seven sawtooth-shaped processes laterally ( Figure 5C View Figure 5 ).

Description

Head. Frons dark brown, slightly pale lower, medially with a few minute, interfrontal setulae. Face brown. Gena dark brown. Postgena brown.

Thorax. Notum and pleura orange-yellow, with dark brown patches and a pollinose pattern. Anepisternum lacking setulae. Scutellum orange-yellow, pale at tip, with a Yshaped brownish patch.

Wing. r-m and dm-cu crossveins clouded.

Legs. Yellow; tibiae with three dark grey rings.

Abdomen. First to fifth tergites yellow, second sublaterally and laterally with black patches; third and fifth with medially protruded, broad, brown-black band along posterior margins, sublaterally with one pair of yellow patches; sixth almost entirely black.

Male terminalia. Epandrium pubescent anteroventrally and on posterior margins; 11 setae near posterior margin ( Figure 5A View Figure 5 ). Surstylus lacking pubescence, with about ten setae basally, and about seven prensisetae apically. Additional plate between cerci and tenth sternite with pubescence, connected to tenth sternite ( Figure 5B View Figure 5 ). Hypandrial posterolateral lobe pubescent ( Figure 5C View Figure 5 ). Paramere lacking pubescence, tripartite distally: apical process with one sensillum, lacking teeth; median process slender, with one sensillum apically; proximal process finger-shaped ( Figure 5C View Figure 5 ).

Measurements. BL 53.67 mm (5 „ paratypes: 3.34–3.97); ThL 51.50 mm (1.45–1.50); WL 53.20 mm (3.10–3.50); WW 51.22 mm (1.20–1.40).

Remarks

This species resembles P. pi ( Toda and Peng, 1990) from Guangdong, China in having the branch of the aedeagal basal bridge hook-shaped, strongly sclerotized. It can be distinguished from P. pi by having the vertical process of gonopod with six to seven pairs of sawtooth-shaped processes (P. pi has only two pairs of horn-shaped processes and the branch of aedeagal basal bridge not bifurcated apically).
