Figs 5–6

Diagnosis

The salient features of the new species include: centre of dorsal margin of periandrium with a short laminal process, base large, apex bifurcated ( Fig. 5J–L ); ventrally around midlength of periandrium with a slender spinose process, slightly curved ( Fig. 5M ); apical part of endosoma bifurcated, margin with small teeth ( Fig. 5J–M ).

Etymology

The specific name is derived from the Latin adjective ‘ furcutus ’, referring to the bifurcate apical part of the endosoma.

Description

MEASUREMENTS. Body length: male 6.5–7.2 mm (N = 8), female 7.2–7.7 mm (N = 4).

COLORATION. General color light brown ( Fig. 5A–B ). Eyes yellowish brown, ocelli faint yellow, semitranslucent. Antenna, vertex and face generally light brown. Rostrum brown. Pronotum and mesonotum brown. Forewing semi-translucent, with many small dark brown spots and irregular smoky speckle stripes. Stigma and veins yellowish brown. Tubercles blackish brown. Hind tibiae yellowish brown. Ventral abdomen yellowish brown.

HEAD AND THORAX. Vertex ( Fig. 5A, C ) as long as wide; lateral carinae strongly elevated, median carina absent. Frons ( Fig. 5D ) 3.6× as long as wide. Pronotum ( Fig. 5A, C ) 1.4× as long as vertex; posterior margin forming an obtuse angle. Mesonotum 1.2× as long as pronotum and vertex combined. Forewing ( Fig. 5B, E ) 2.2 × as long as wide, with fourteen apical cells and seven subapical cells; RP with 5 branches; MP with 5 branches: MP 11, MP 12, MP 2, MP 3 and MP 4; fork MP 1 + MP 2 basad of fork MP 3 +MP 4. Metatibiotarsal formula 8/8, second segment of hind tarsus with three platellae.

MALE GENITALIA. Pygofer ( Fig. 5F–G ) in ventral view symmetrical; in lateral view, lateral lobes arcuate and extended caudally. Medioventral process lanceolar in ventral view. Anal segment ( Fig. 5F, H ) flat tubular, dorsal margin slightly convex, ventral margin curved, apical margin expanded downward in lateral view; 2.5× as long as wide in dorsal view; anal style strap-shaped, not extending beyond anal segment. Gonostyli ( Fig. 5G, I ) symmetrical ventrally; in inner lateral view, base of ventral margin concave, apical margin rounded. Aedeagus ( Fig. 5J–M ) with four processes. Centre of dorsal margin of periandrium with a short laminal process, base large, apex bifurcated, directed dorsocaudad; ventrally around midlength of periandrium with a slender spinose process, slightly curved, directed caudad. Endosoma large, basal part highly sclerotized, apical part with two processes bearing small teeth: one wide and flat, with its tip directed ventrad, the other directed ventrocephalad.

FEMALE GENITALIA. Tergite IX ( Fig. 6A–B, D ) moderately sclerotized, with a large,nearly elliptical wax plate. Anal segment ( Fig. 6C ) rectangular, 1.9 × as long as wide in dorsal view, anal style linguiform. Gonapophysis VIII ( Fig. 6E ) elongate, slightly curved upwards. Gonapophysis IX ( Fig. 6F ) with one middle tooth, distance ratio between middle tooth to apex and length of denticulate portion 1.6. Gonoplac ( Fig. 6G ) rod-like, 5.2 × as long as wide in lateral view. Posterior vagina pattern as shown in Fig. 6H .

Distribution

China (Guizhou).

Remarks

This species was identified with the help of Pei Zhang, and is similar to Andes bifidus sp. nov. in appearance, but differs in: (1) middle dorsal margin of periandrium with a short laminal process, base large, apex bifurcated (dorsal margin of periandrium with a spinose process in A. bifidus ); (2) ventrally around midlength of periandrium with a slender spinose process, slightly curved ( A. bifidus without a process in this position); (3) apical part of endosoma bifurcated, margin with small teeth (endosoma not bifurcated in A. bifidus ).
