Types.
Holotype ♂ (NMPC), INDONESIA. South Kalimantan: Kandagan distr., 17 km NE of Laksado vill., 900 m, 3-22.IX.1997, leg. S. Jákl. Paratypes. 11♂♂ (JBCB), same data as holotype; MALAYSIA. Sabah: 2♂♂ (TARI), Trusmadi, 1.X.2014, leg. Y.-T. Wang; 2♂♂ (TARI), same but with “2.X.2014”.
Description.
Length 5.1-5.8 mm, width 1.8-2.3 mm. Body color (Fig. 26D-F View Figure 26 ) yellowish brown, head and pronotum metallic green, prosternite dark brown, elytra yellowish but laterally and apically metallic green, antenna black except three basal antennomeres paler. Antennae filiform in males (Fig. 28A View Figure 28 ), length ratios of antennomeres I-XI 1.0: 0.3: 0.8: 0.9: 0.8: 0.8: 0.8: 0.8: 0.8: 0.7: 0.8, length to width ratios of antennomeres I-XI 3.9: 1.8: 3.4: 4.4: 5.2: 5.3: 5.9: 5.8: 5.6: 4.6: 4.6. Elytra elongate, parallel-sided, 1.9-2.0 × longer than wide; disc with dense, coarse punctures, arranged into longitudinal rows, with one indistinct longitudinal ridge between two longitudinal rows of punctures, with dense, short setae along ridges. Tarsomeres I of front legs slightly swollen in males. Aedeagus (Fig. 28B-D View Figure 28 ) slender, 4.7 × longer than wide; widest at basal 2/5, narrowed towards apical 1/7 and basal 1/5, parallel from apical 1/7 to apex, apical margin truncate, slightly depressed medially; tectum extremely slender, from apical 1/5 to basal 1/4; recurved in lateral view, angular at apical 1/6, straight from apical 1/6 to apex; ventral surface entirely sclerotized, triangular sclerites absent; internal sac with elongate endophallic sclerite, 0.9 × as long as aedeagus, apex with one pair of small processes directed ventrally, one pair of longitudinal rows of hair-like setae basally connected with apex of endophallic sclerite, one pair of lateral sclerites large and hook-like, subequal in length but with different apical shapes; basal opening medially closed.
Female unknown.
Variation. Specimens from Sabah have slender lateral sclerites of the internal sac (Fig. 28E View Figure 28 ).
Diagnosis.
Borneotheopea kalimantanensis sp. nov. is easily distinguished from the other member of the genus, B. jakli sp. nov., based on the distinct ridges on the elytra and yellowish brown ventral surface (Fig. 26E, F View Figure 26 ) (indistinct ridges on the elytra and metallic blue ventral surface in B. jakli sp. nov. (Fig. 26A-D View Figure 26 ). Males of B. kalimantanensis sp. nov. are also easily separated from those of B. jakli sp. nov. by the anterior directed apex and angular process at apical 1/6 of the aedeagus (Fig. 28C View Figure 28 ) (the apex of aedeagus directed ventrally and without angular processes in B. jakli sp. nov. (Fig. 27D View Figure 27 )), extremely slender tectum (Fig. 28B View Figure 28 ) (short and wide tectum in B. jakli sp. nov. (Fig. 27C View Figure 27 )), presence of clustered setae at apex of median elongate sclerite (Fig. 28B, C View Figure 28 ) (without setae at apex of median elongate sclerite in B. jakli sp. nov. (Fig. 27C-E View Figure 27 )).
Etymology.
The new species is named for its type locality.
