Diagnosis. See “Diagnosis” under “ coelestinus ” species group.

Description. Habitus. Specimens of middle to large size (BL: 12.45–14.40 mm, BW: 5.2–6.0 mm), with ovate and flat body ( Figs 6A, D ). Ratios and measurements. See Table 2. Color and luster. Head and ventral surface black; pronotum and elytra bluish, with blue luster more distinct on elytra than on pronotum; antennae and palpi flavous to rufopiceous; legs rufopiceous. Head moderately shiny, without iridescence; pronotum and elytra very shiny, with strong iridescence; sternal part of meso- and metathorax, and abdomen shinier and more iridescent than ventral part of head and prothorax. Punctuation. Dorsal surface without punctuation; meso- and metepisternum, and metasternum at sides more densely and strongly punctate than proepisternum and prosternum at sides; abdominal ventrites 1–5 punctate at sides and submedially, ventrite 6 punctate at apex. Head. Less than half as wide as pronotum ( Table 2). Mentum tooth short, truncate, with paramedial border distinct ( Fig. 6F ). Thorax. Pronotum ( Fig. 6E ) with sides barely rounded toward posterior angles (PW/PB: 1.02–1.06); maximum width in posterior fifth; laterobasal impressions indistinct; base slightly sinuate; anterior angles rounded, weakly projected. Prosternum with median longitudinal sulcus shallow but distinct, deeper than in species from “ cribristernis ” group; prosternal process elliptic, with subpointed apex ( Fig. 6G ). Metepisternum longer than wide (MA/MM: 0.82–0.87), with lateral margin convex, coadunation with epipleuron short, located near middle ( Fig. 6B ). Elytra. Apical sinuation strong, well defined. Basal margin distinct laterally, forming a minute denticle at shoulder, disappearing medially at level of stria 3. Parascutellar striola quite reduced, shallowly punctate, much less impressed than other striae; striae punctate. Intervals 1–6 flat, 7 subconvex, 8 more convex than other medial intervals. Legs. Metacoxal basal sulcus reduced laterally, ending at medial third. Male mesotibia markedly curved at basal third and dilated distally. Protarsomeres 1–3 of male moderately dilated, with second segment slightly wider than long (W/Lp2: 1.19–1.25). Male genitalia. Median lobe ( Figs 7A, B ) with basal bulb relatively short, bent ventrally; angle between basal bulb and shaft obtuse; shaft long, slightly swollen medially; apex short, straight; apical lamella short, rounded, with right margin curved to left. Female genitalia. Basal gonocoxite with two large and several minute lateroapical setae. Apical gonocoxite elongate, with two dorsolateral ensiform setae different in size, large dorsomedial ensiform seta near base, and nematiform setae at apex ( Fig. 7C ). Bursa copulatrix without sclerite; spermatheca moderately long, differentiated, with seminal canal long and narrow, and receptaculum short and wide, twisted apically; spermathecal gland connected near apical fifth of seminal canal ( Fig. 7D ).

Distribution. Malaysia (Kuala Lumpur, Sarawak, Sabah), Brunei, Indonesia (Sumatra, Borneo). New species for Brunei and Indonesia.

Bionomics. Labels data indicate that specimens were collected most commonly at light. In the states of Sarawak and Sabah, Malaysia, they were caught near banks of large rivers ( Sarawak River, Rajang River, Baram River, and Padas River). Like P. cribristernis , this species inhabits areas with a wide spectrum of altitude; for instance, in Sabah State, it was gathered near sea level (Tawau) and at up to 2000 m (Mount Trus Madi).
