Diagnosis.

Manocoreus hsiaoi sp. nov. can be recognized from all other species of Manocoreus by the following characters: lateral margin of pronotum black (Figs 4A View Figure 4 , 12D View Figure 12 ); punctures on the discal region of pronotum not black (Fig. 12D View Figure 12 ); connexivum with black spots (Fig. 3A, C View Figure 3 ); the middle portion of corium with large black spots (Fig. 3A, C View Figure 3 ); male median ventroposterior process of genital capsule long and tuberculate (Figs 4E View Figure 4 , 5D View Figure 5 , 14D View Figure 14 ).

Body brownish yellow, dorsum of head with dense black punctures, underside of head with dense punctures concolorous with body surface (Fig. 4B View Figure 4 ), compound eyes dark red, ocelli reddish; labium yellow, distal one fourth of segment IV black; antennomeres I-III brownish yellow, antennomere IV paler, apical portion of antennomeres II and III blackish, antennomere I with moderately dense small black tubercles, small tubercles on antennomeres II and III more scattered and paler, each segments with short semi-erect setae; lateral margin of pronotum black (Fig. 4A View Figure 4 ); collar, callus area, area near lateral margin and posterior margin with black punctures, central discal region of pronotum with yellow punctures; propleura and prosternum yellow, propleura with black punctures (Fig. 4C View Figure 4 ); scutellum and corium brownish yellow, with brown to black punctures, meso- and metapleura, and meso- and metasternal yellow, meso- and metapleura with black punctures; legs yellow, only apical area of tarsal segment III blackish brown, femora and tibiae of each leg with moderately dense small brownish tubercles, femora, tibiae and tarsi of each leg with short semi-erect setae, setae on apical half of tibiae and tarsi denser; corium with a large and more or less central black spot, membrane grey, basal area darker; middle and apical portion of connexivum of each segment black, venter of abdomen yellowish brown, abdominal terga with a median black spot on each side of segments II-VII; a pair of smaller black spots located near anterior margin of segments III to VII (Fig. 3 View Figure 3 ).

Structures.

Head. Width of head ~ 1.07-1.26 × as wide as median length of head, ~ 1.71-1.80 time as wide as interocular distance; antennomere I slightly shorter than antennomere II, ratio of antennomeres I:II:III:IV = 1:1.03:0.84:0.62; apex of labium surpassing posterior margin of mesocoxae, not reaching to anterior margin of metacoxae. Pronotum ~ 1.43-1.60 × as width across humeral angles as its median length; scutellum ~ 0.96-1.16 × as long as its width. Anterior peritreme of metathoracic scent gland slightly larger than protruding posterior peritreme, gyrification of evaporatorium deep (Fig. 4C, D View Figure 4 ). Pregenital abdomen. Abdomen oblong, spiracles situated near lateral margin of abdominal sterna III-VII (segments III to VIII in female), before middle line of each segment; sternum VII of male strongly concave medially, length of concave part ~ 1/2 length of sternum VIII in ventral view; in female plica triangular, and partly exposed out of sternum VI, posterior margin of sternum VII sinuated. External male genitalia. Genital capsule opening dorsally (Fig. 4E, F View Figure 4 ), dorsoposterior rim wide, median projection conspicuous, triangular (Fig. 5D View Figure 5 : mdp), posterior margin of genital capsule broadly sinuate and ventroposterior process median (Fig. 5D View Figure 5 : mvp), lateral portion of posterior margin roundly produced on each side (Fig. 5D View Figure 5 ); dorsal margin of base of paramere near straight, ventral region of base of paramere with triangular lobe (Fig. 5E-G View Figure 5 ), distal portion sickle-shaped (Fig. 5E-G View Figure 5 ); phallus with a sclerotized articulatory apparatus (Fig. 5A-C View Figure 5 ), phallotheca barrel-shaped, unarmed (Fig. 5A-C View Figure 5 : phth), conjunctiva rigid and complex, with one pair of membranous processes and a pair of slender, triangular adjacent ventral conjunctival sclerites (Fig. 5B, C View Figure 5 : vcs), aedeagus coiled, strongly sclerotized, distal portion tubular, obliquely truncate apically (Fig. 5A-C View Figure 5 : aed).
