Notes on types and synonyms. Parena phongsalyensis Kirschenhofer: This species was described from N. Laos without comparison with the very similar species P. quadrisignata. We examined the types of the two species and found that they are slightly different in the following three aspects: the background color of P. phongsalyensis is much darker; the humeral patches smaller and slightly distant from elytra base, and the subapical patches have the oblique extension very narrow and almost invisible. We cannot compare their male genitalia because the types of P. quadrisignata are females. Instead, we examined several specimens from west Yunnan, which geographically intermediate and present intermediate states of these above characters (Fig. 43F). These specimens are almost identical to the holotype of P. phongsalyensis in male genitalia (Fig. 45). Thus, we treat P. phongsalyensis as a junior synonym of P. quadrisignata.

China: 1 female (IZAS), "Yunnan, Fugong county, Pihe, Zhiziluo, 2005.8.20, Liang Hongbin lgt.". 1 male, 1 female (CAS), "Yunnan, Tengchong, Qushi, Xiangyangqiao, N25.21221, E98.57836, 1500 m, 2006.VI.4 D, Kavanaugh D., Brett R. lgt." <Figs 11H, 45A>. 1 male (IZAS), "Yunnan, Baoshan, Mangkuan, Baihualing, N25.21221, E98.57836, 1635 m, 2005.VI.2 D, Kavanaugh D. lgt." <Fig. 43F>. 1 male (IZAS), "Xizang, Mêdog county, Dêxing, Wainlang vill, alt. 1251 m, 2020.IX.4 D2, N29.36709, E95.34012, Liang Hongbin lgt.".
Comparisons. This species is easily distinguished from all other species of subgenus Bothynoptera by dorsum dark brown with black patches on elytra. It is also distinctly larger than all other species of the P. tripunctata group. The male genitalia of this species are very similar to those of P. tripunctata, but the apical lamella is rounded-triangular and not bent toward the dorsum. In P. tripunctata, the apical lamella is rounded-truncate and weakly bent toward the dorsum.
Description. Body length 8.0– 9.1 mm. Dorsum dark brown, elytra background slightly lighter than pronotum and head; elytra with two pairs of black patches: basal group elongate, very close to elytra base, occupying intervals 5 to 7 or 8, subapical group nearly round, occupying intervals 4 to 7, often with an oblique extension backward to elytral suture; legs, antennae, and mouthparts dark brown; venter dark brown. Labrum slightly dilated to apex, apex very weakly emarginate. Pronotum nearly quadrate, PW/PL = 1.20–1.28, usually slightly narrower than head, PW/HW = 0.93–1.00; lateral explanations narrow; widest at anterior third, slightly rounded at anterior half, and then moderately to strongly sinuate before posterior angles; posterior angles nearly rectangular with slightly distinct apex. Elytra slightly dilated to apex, surface without microsculpture; striae shallowly incised, with fine puncture rows; intervals with sparse punctures. Males with biseriate adhesive setae on apical third 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 slightly expanded near middle; apical lamella thick and short, rounded triangular, LL subequal to LW. Endophallus with squamate sac not divided. Gonocoxite II of ovipositor nearly quadrate, length subequal to basal width, apex straight, with five ensiform setae, four of them equally arranged on apical margin, a shorter one on outer margin.
