Diagnosis
Paridea (Semacia) sexmaculata is similar to Paridea (Semacia) kaoi sp. n. and Paridea (Semacia) angulicollis with the depression on postscutellar common area of males but flat and replaced with a black spot in females. It differs by the presence of a black spot near the lateral margin instead of black stripe along lateral margin in Paridea (Semacia) kaoi sp. n. and Paridea (Semacia) angulicollis, the well sclerotized and extremely slender penis (Fig. 37) and processes on eighth abdominal tergite of males (Fig. 42), and the presence of two acute processes on the fifth abdominal ventrite in females (Fig. 41).
Males
Length 5.1–6.0 mm, width 2.9–3.3 mm. Head and prothorax yellowish brown (Figs 28–30), labrum black, antenna blackish brown; scutellum pale yellow; elytra pale yellow, postscutellar common area depressed; with one pair of black spots near lateral margin at same level with excavation, spots extending inwards in some individuals (Fig. 31; one pair of large black spots subapically, lateral margin and epipleuron yellow; meso- and metathoracic ventrites black; legs yellowish brown, apical half of tibia, and tarsi black; abdomen yellow. Eighth abdominal tergite (Fig. 42) strongly sclerotized, transverse and slender, with one pair of extremely slender and curved processes. Pygidium slightly projecting beyong elytral apices. Penis (Figs 37–38) very slightly asymmetric, weakly narrowed at apical 1/6; apex narrow, tubular, and extremely long; moderately curved from lateral view; endophallic sclerites with one elongate sclerite and one layer of small setae.
Females
Length 5.3–6.2 mm, width 3.1–3.4 mm. Similar to male; elytra without excavation but with transverse black spot instead (Fig. 32), sometimes connected with lateral black spots (Fig. 33). Apical margin of last abdominal ventrite (Fig. 41) with one pair of small, wide, and acute processes at middle, with shallow notch between processes. Pygidium slightly projecting beyong elytral apices. Gonocoxae (Fig. 39) slender, apex of each gonocoxa with eight setae from apical 1/4 to apex; connection of gonocoxae extremely slender, base slender. Sternite VIII (Fig. 40) weakly sclerotized; apex wide, apical margin slightly concave at middle, surface with dense long setae along apical margin, spiculum short. Spermathecal receptaculum (Fig. 43) slightly swollen; pump much longer than receptaculum, strongly curved; spermathecal duct short, stout, shallowly projecting into receptaculum.
Distribution
Taiwan, China (Hunan). It is widespread in Taiwan (Fig. 19). Yang (1991)[6] indicated that this species was also found in Hebei, Beijing, Jiangsu, Shanghai, Zheiang, Fujian, and Hainan provinces of China without voucher specimens. These records require confirmation.
Host plant
Cucurbitaceae: Gynostemma pentaphyllum (Thunb.) Makino.
Notes
Two specimens of the type series of Paraulaca taiwana were misidentified. They are Paridea (Semacia) sexmaculata and labeled as follow: 1♂: “Shiigo [= Maopu, Wufeng township] Chikuto [= Chutung] [p] / SHINCHIKU [= Hsinchu county] [p] / 27–30.VI.1934 [p] / COL. M. CHUJO [p, w] // COTYPE [p, circle label with yellow letters] // Paraulaca [h] / taiwana Chûjô [h] / DET. M. CHUJO [p, g] // No. 1339 [p, w]” (TARI); 1♂: “Formosa [p] / Karenko, [= Hualien] – 19. [p] / VII 20-VIII 4. [p] / T. Okuni, [p, w] // COTYPE [p, circle label with yellow letters] // Paraulaca [h] / taiwana Chûjô [h] / DET. M. CHUJO [p, g] // 2185 [p, w]” (TARI).
