Zhouwei Yuan and Xiao Yang"; Record Level : collectionCode: Insects ; basisOfRecord: Preserved Specimen Description Body length, males 2.9-3.0 mm, females 2.8-2.9 mm. Vertex (Fig. 1 A) pale yellow, with pair of small black spots. Coronal suture short, with two irregular markings on sides (Fig. 1 A and C). Eyes greyish-black. Pronotum yellow, with irregularly dark brown or black patches (Fig. 1 A and C). Scutellum light yellow, with basal triangles black and transverse impression distinct (Fig. 1 A and C). Face light brownish-yellow, frontoclypeus with black patches at sides basally (Fig. 1 D). Forewing milky white, with light brown patches. Abdominal apodemes small, not extended to hind margin of 3rd sternite (Fig. 2 G). Diagnosis Male genitalia. Pygofer lobe broad, with many microtrichia and fine setae scattered on lateral surface, occasionally with long fine setae. Pygofer dorsal appendage expanded basally, caudal margin round (Fig. 2 A). Subgenital plate short, with three long macrosetae on lateral surface and row of peg-like setae along dorsal margin to medium area, with sparse fine small setae on apical portion (Fig. 2 B). Style long, with pre-apical lobe moderately large (Fig. 2 C). Preatrium of aedeagus short and aedeagus shaft slender; at the base of aedeagus with small appendages; dorsal apodeme branched apically; gonopore apical on ventral surface (Fig. 2 D and E). Connective Y-shaped, arms and stem developed, with long and thin central lobe (Fig. 2 F). Female genitalia. Female 7th sternite as in Fig. 3 A and B. Valvula I elongate, curved dorsad, apical portion pointed, with dense imbricate carving (Fig. 3 C and D). Valvulae II elongate, gradually expanded from base to top and divided into two blades, one of which has dentate protrusions (Fig. 3 E and F). Valvula III leaf-like, with microtrichia on dorsal margin and apex (Fig. 3 G and H). Etymology The new species is named from the Latin word "bifurcatus" , referring to dorsal apodeme branched of the aedeagus. Taxon discussion This species has a similar aedeagus shape to Mitjaevia protuberanta Song, Li, Xiong, 2011 ( Song et al. 2011 ), but it can be distinguished by the aedeagal shaft slender; pre-atrium of aedeagus short, dorsal apodeme branched apically and without triangle-like processes subapically. Distribution. Guizhou Province.
