Xie & Yu, 1993: 192 (type locality: Shaping; holotype in IZAS); Kirschenhofer, 2006: 89.

Parena yunnana Kirschenhofer, 1994: 1019 (type locality: Yunnan: Lijiang; holotype in NMW: Naturhistorisches Museum Wien, Vienne, Austria); Kirschenhofer, 2006: 89. Syn. nov.

Type material examined. Parena shapingensis Xie & Yu : Holotype (IZAS, Fig. 40A ): male, body length = 6.5 mm, board mounted, " Shaping / 27.IX.1943 " [in Chinese], " HOLOTYPE " [red label], " Parena shapingensis / Xie et Yu / Xie Weiping det. 1991", "IOZ(E) 211403" [blue label] < Fig. 41 >.

Notes on types and synonyms. Parena shapingensis Xie & Yu : The holotype of this species is briefly labeled as "Shaping, 27.IX.1943 " in handwritten Chinese without other explanation of this locality. In the original description, the type locality was explained as Guangdong (Shaping), referring to Shaping town of Heshan city. However , this speculation could be wrong because Guangdong is far from all other known localities of this species. The handwriting of the locality label is identified that of a famous Chinese entomologist, Prof. Sicien Chen. He worked in Academia Sinica in Chongqing from 1939 to 1946. Thus the type locality "Shaping" is very likely to refer to Shapingba (N29°32' E106°27') in Chongqing City .

Parena yunnana Kirschenhofer : We did not examine the type of this species, but the specimens from very close to its type locality that we examined are perfectly in accord with the original description and illustration of P. yunnana . So, we confirmed that P. yunnana is identical to P. shapingensis in external and male genital characters.

Non-type material examined. 1 female (HBUM), " Sichuan, Lixian, Shangmeng , 2009.VII.24–25, Gao ZH., Niu YP. lgt." . 1 male (IZAS), " Yunnan, Lijiang, Yulongshan , 1979.VIII.12, Zou Huanguang leg." < Fig. 40B >. 1 male (CRS), " China Yunnan, 1800 m, Lijiang 23.6–21.7, 26.53N 100.18E, lgt. S. Becvar 1992" . 1 male (IZAS), " Kunming, World Horticultural Expo Garden , 2004.6.27, Ou Xiaohong lgt." .

Comparisons. This species is easily distinguished from all other species of subgenus Bothynoptera by the small size and elytra light yellowish brown with an indistinct large pale patch. The male genitalia of this species are very similar to those of P. tripunctata , but differ in the ventral margin of median lobe, which is nearly straight, and the apical lamella not bent dorsally.

Description. Body length 6.5–6.7 mm. Head and pronotum yellowish red; elytra gradually graded from yellowish brown basally to pale yellow subapically, apical eighth of elytra yellowish red, forming a vague, large pale patch on the middle of elytra; legs, antennae, and mouthparts yellowish brown; venter yellowish brown. Labrum slightly dilated to apex, apex very weakly emarginate. Pronotum nearly cordate, PW/PL = 1.26–1.36, slightly narrower than head, PW/HW = 0.93–0.97; lateral explanations narrow; widest at anterior third, well rounded at anterior half, and then strongly sinuate before posterior angles; posterior angles nearly rectangular with distinct apex, slightly pointed outward. Elytra slightly dilated to apex, surface without microsculpture; striae shallowly incised, with fine puncture rows; intervals with very sparse punctures. Males with biseriate adhesive setae near apex of mesotarsomere 2 and apical two-thirds of mesotarsomere 3. Median lobe of aedeagus very stout, in dorsal view apex distinctly bent to right; in lateral view ventral margin nearly straight before middle; apical lamella thick and short, LL much smaller than LW, apex rounded-truncate; in lateral view apical lamella not bent dorsally. Endophallus with squamate sac partly divided. Female ovipositor not studied.
