Diagnosis.

Adults of Anatrimonia yunnanensis sp. nov., A. jungchani sp. nov., and A. yuae sp. nov. are characterized by their yellow elytra (Fig. 12). Adults of A. yunnanensis sp. nov. differ from those of A. yuae sp. nov., and A. jungchani sp. nov. in having smaller body sizes (<4.3 mm) and black metathoracic ventrites (Fig. 12 G – I) in contrast to larger body sizes (> 4.3 mm) and yellow metathoracic ventrites of A. yuae sp. nov. and A. jungchani sp. nov. (Fig. 12 A – F). The aedeagi of these species are diagnostic: strongly and apically narrowed but with truncate apex in A. yunnanensis sp. nov. (Fig. 20 C, D), gradually and apically narrowed but narrowly rounded apex in A. jungchani sp. nov. (Fig. 13 C, D), and strongly and apically narrowed but with acute apex in A. yuae sp. nov. (Fig. 19 C, D); endophallic sac composed of one slender endophallic sclerites and two small sclerites in A. yunnanensis sp. nov. (Fig. 20 C, D) and A. jungchani sp. nov. (Fig. 13 C, D), only one slender endophallic sclerite in A. yuae sp. nov. (Fig. 19 C, D).

Description.

Length 3.5–4.2 mm, width 1.6–1.9 mm. General color pale yellow (Fig. 12 G – I); antennae blackish-brown except for three basal antennomeres; legs yellowish-brown, outer margin of tibia darker; metathoracic ventrites black. Antennae (Fig. 20 A) filiform in males, ratio of lengths of antennomeres I – XI 1.0: 0.5: 0.9: 0.7: 0.6: 0.6: 0.7: 0.6: 0.6: 0.5: 0.8; ratio of length to width of antennomeres I – XI 3.5: 2.5: 4.0: 3.2: 2.8: 2.8: 3.0: 2.7: 2.5: 2.4: 3.5; similar in females, ratio of lengths of antennomeres I – XI (Fig. 20 B) 1.0: 0.5: 0.9: 0.7: 0.6: 0.6: 0.6: 0.6: 0.5: 0.5: 0.7; ratio of length to width of antennomeres I – XI 4.1: 2.2: 3.9: 3.3: 2.8: 2.8: 2.9: 2.9: 2.5: 2.5: 3.4. Pronotum 1.73–1.79 × wider than long; disc with sparse, coarse and fine punctures at sides; lateral margins slightly rounded and basally narrowed, basal margin and apical margin straight; disc with a broad transverse depression at each side, median longitudinal groove obvious. Elytra 1.52–1.68 × longer than wide; with extremely dense setae, parallel sided, apex convergent. Aedeagus (Fig. 20 C, D) slender, ~ 4.7 × longer than wide; lateral margins parallel from base to middle, apically narrowed from middle, apex tubular, apical margin narrowly rounded; slightly and curved in lateral view; endophallic sac with one flagellum-like sclerite, apically abbreviated, basal margin truncate, with two additional slender sclerites near base of flagellum-like sclerite. Gonocoxae (Fig. 20 G) short and broad, apically narrowed, apex widely rounded; each gonocoxa with 14 or 15 short setae at apex, both gonocoxae basally conjunct with one extremely slender and longitudinal sclerite, base triangular. Ventrite VIII (Fig. 20 E) well sclerotized, median depression at middle of apical margin; disc with sparse, short setae near apical margin; spiculum slender but short. Spermathecal receptaculum (Fig. 20 F) moderately swollen; pump wide and curved; sclerotized spermathecal duct wide but short.
