description: [36] Parena (Parena) pendleburyi Andrewes, 1931
Habitus: Figs 69E, 69F. Male genitalia: Fig. 72. Gonocoxites of ovipositor: Fig. 11T.
Andrewes, 1931b: 484 (type locality: Mt. Kinabalu; holotype in NHML).
Type material examined. Parena pendleburyi Andrewes: Holotype (NHML, Fig. 69E): male, body length = 8.2 mm, pin mounted, "Mt. Kinabalu, / Brit. N. Borneo. / B.M. 1931-386", "B. N. BORNEO. / Mt. Kinabalu, / Lumu Lumu, / 5500 ft. / April 10-19. 1929." [pink label], "Type" [round label with red circile], " Parena / pendleburyi / Type Andr. / H.E. Andrewes det." <Fig. 72>.
Non-type material examined. 1 female (IZAS), "Boreno: Sahah, Keningau district, Jungle Girl Camp. N5.4430, E116.4512, 1182 m; Shi H.L. & Liu Y. lgt. light trap, Ins. Zoo., CAS. 2016.V.1 N" <Figs 11T, 69F>.
Comparisons. This species differs from other species of the subgenus by the combination of: elytra metallic green with strong reddish copper lustre on humeri and subapices; postgenae without suborbital setae, and males with adhesive setae on mesotarsomere 1. It is similar to P. monticola and P. bicolor in having the elytra entirely metallic green. Comparisons are provided under those species.
Description. Body length 7.4–8.2 mm. Head dark brown, strongly polished, mouthparts yellowish brown, apex and inner margin of mandibles dark brown; basal four antennomeres reddish brown, apical ones same color or slightly darker; pronotum dark brown to piceous, lateral explanations slightly lighter; elytra metallic green, with strong reddish copper lustre near humeri and outer subapical regions; elytral suture dark brown, metallic behind middle; elytral lateral margins and epipleura piceous with strong metallic hue; legs yellowish brown, apices of femora piceous with strong metallic hue; venter of thorax dark brown, abdominal sternum piceous. Vertex with sparse fine punctures; postgenae without suborbital setae; antennae barely extended to pronotal base; labrum quadrate, apex nearly straight; mentum with a pair of minute median setae. Pronotum sub-cordate, PW/PL = 1.31–1.35, slightly narrower than head, PW/HW = 0.97–0.98; widest at anterior third, strongly narrowed to base, distinctly sinuate before posterior angles; posterior angles widely obtuse; disc with very fine punctures. Elytra slightly dilated to apex, without microsculpture; striae very shallowly incised, with fine puncture rows; intervals slightly convex, with very sparse punctures; disc with very faint depressions near basal third of intervals 3 and 4. Males with biseriate adhesive setae on apical half of mesotarsomere 1, and almost full length of mesotarsomeres 2–3. Apex of abdominal sternite VII weakly emarginate in males. Median lobe of aedeagus stout (AL/AW = 3.9), right margin barely sinuate before apical lamella; apical lamella thick, ovate in dorsal view, LL slightly smaller than LW, not declined to left; subuliform in lateral view, apex not bent upward. Endophallus with very large flared basal expansion of primary sclerite; flagellum thick, extending almost to the base of apical orifice; apical sclerite widely V-shaped, well-defined, basal core distinct, slightly extended forming a wide transverse scaled belt; basal sheath coarsely scaled, apical sheath finely scaled, similar size as basal sheath; squamate sac well divided, near middle of median lobe, dorsal to squamate sheath; proximal sac very large, distal sac much smaller and closer to apex than proximal sac. Gonocoxite II of ovipositor nearly quadrate, slightly longer than width, apex concave, angulate near inner apical angle, with two ensiform setae on outer apical angle, two on inner apical angle, and one near middle of apical margin.
