Apsiphortica melanogaster Chen , sp. nov.

( Figures 7–9 )

Diagnosis

Paramere bifurcated from base, anterior one with pubescence ( Figure 7 ); aedeagal median rod strong, black, bifurcated basally ( Figure 7 ); aedeagal outer membrane with about 12 sclerotized, long, apically hook-like pieces ( Figure 7 ).

Description

Some characters commonly seen in A. longiciliata are not referred to in the following description.

Thorax. Brown-yellow, with a broad black stripe medially on scutum and a few dark brown patches on pleura. Scutellum grey-brown.

Legs. Yellow except black third to fifth tarsomeres and apical part of all tibiae.

Abdomen. Second to fourth tergites yellow, each with narrow, dark brown band on posterior margin; fifth and sixth tergites nearly black.

Male terminalia. Epandrium not so strongly protruded at anteroventral corners, with about 30 setae near posterior margin and pubescence ( Figure 7 ). Surstylus broadened, apically protruded, with a few setulae on apical margin ( Figure 7 ). Tenth sternite with small nonpubescent median piece ( Figure 8 ). Aedeagal median rod slightly curved dorsad, basally with strong dorsal process ( Figure 7 ). Ventral branches of aedeagal apodeme apically separated from each other.

Female terminalia. Eighth sternite (oviscapt) slightly rhombus, nearly entirely pubescent and densely setigerous, with two sclerotized lobe-like processes distolaterally ( Figure 9 ).

Measurements. BL54.00 mm in the holotype (range in 5 „ and 4R paratypes: 4.00–4.50); ThL 52.08 mm (2.10–2.55); WL 53.30 mm (3.30–3.95); WW 51.50 mm (1.45–1.60).
