Scymnus (Pullus) baoxingensis Yu , new species

( Fig. 13)

Description. Male. Length 1.65 mm, width 1.10 mm. Form elongate oval with sides nearly parallel at middle, dorsum moderately convex. Head yellowish brown. Pronotum reddish brown with slightly lighter lateral parts. Elytra black, apical margin brown, bor­ der between colors indistinct. Underside brown, prosternite and meso­ and metathoraces black. Legs brown, middle and hind coxae black. Interocular distance about 2/5 head width. Innerocular margins arcuate, divergent anteriorly. Frons flat, punctation very fine, dense. Antenna 11­segmented proportions as illustrated ( Fig. 13k). Maxillary palpus terminal segment distinctly divergent distally, distal side strongly oblique. Pronotum punctation similar to head. Elytral punctation slightly coarser, hairs arranged in weak Sform. Prosternal carinae slightly convergent anteriorly. Postcoxal line of first abdominal sternite complete, slightly arcuate, reaching about 2/3 length of the sternite; enclosed area finely punctate, posterior 1/2 smooth. Hind margin of fifth abdominal sternite evenly arcuate; sixth sternite apex slightly emarginate. Genitalia: Sipho ( Fig. 13a) relatively slender; siphonal capsule with stout outer process, slightly more slender inner process; apex of sipho simple, surrounded by membrane, without distinct appendix. Tegmen ( Fig. 13b, c, and i) slender; median piece of tegmen nearly parallel­sided for basal 1/4, then slightly divergent to 1/3 from apex, then converging to sharp point in ventral aspect. In lateral aspect, median piece thickest at base, gradually converging to tip. Lateral lobes of tegmen club­like, distinctly shorter than median piece.

Female. Length 1.90 mm, width 1.20 mm. Externally similar to male except for brown head, arcuate hind margin of sixth sternite. Receptaculum seminis as illustrated ( Fig. 13 m).

Distribution. China (Sichuan).

Type Series. Holotype: (Ƌ), Sichuan: Baoxing: Qiaoqi (30.3 N, 102.8 E), V­1996, Guo H. et al. leg. ( BAAF) . Paratype: (1 ♀, same data as holotype) ( CAF) .

Etymology. The specific name refers to the type locality.

Remarks. The new species is similar to S. (P.) ancontophyllus Ren and Pang 1993 , but the new species has a smaller tegmen and a median piece with the base nearly parallel sided.
