Description
Description of holotype. Habitus of female holotype as in Fig. 1. Body narrow, longitudinal, matt, setose, punctuate. Body length 12.0 mm, widest in humeral part of elytra, humeral width 3.0 mm, four times longer than wide.
Head slightly longitudinal, little narrower than pronotum in middle, black, setose, finely punctuate, widest across eyes. Pubescence golden-yellow. Eyes large, longitudinal, excised, in excision with base of antenna. Maxillary palpus black, palpomeres short, penultimate palpomere is distinctly shorter than ultimate palpomere. Ultimate palpomere rounded, truncate. Antennae filiform, antennomeres narrow, antennomere 1 distinctly wider. Antennae dark brownish-black with golden-yellow pubescence and distinctly punctuate. Antennomeres 3 and 4 stretched into distinct spines on the inner side. Spine on the antennomere 3 finely longer than in antennomere 4. Antennae reaching half elytra length. Ratios of relative lengths of antennomeres 1-11 equal to: 0.74 : 0.27 : 1.00 : 0.58 : 0.64 : 0.65 : 0.63 : 0.44 : 0.42 : 0.40 : 0.54.
Pronotum slightly elongate, black, with short black pubescence and golden-yellow pubescence near sides, in the middle, on the base and on the front edge; 1.4 times longer than its width at base, 1.35 times longer than its width in the middle and 1.1 times longer than its width at the widest point. Roundly punctuate with large punctures. Interspaces between punctures very narrow. Anterior margin distinctly rounded, posterior margin very slightly excised and rounded in the middle. Sides rounded in the middle. Surface with long, black, and comparatively sparse setae.
Scutellum transverse, black, with golden-yellow pubescence.
Elytra 7.9 mm long and 3.0 mm wide, black, distinctly punctuate, with short black and golden-yellow pubescence. Longitudinal band on the base of elytra, rounded band from the suture to lateral margins (but suture and margins narrowly black), longitudinal band from previous band place to two thirds elytra length, transverse band from two thirds elytra length up to four fifth elytra width and tear-shaped spot in the apical part of elytra with golden yellow pubescence; but margins distinctly black. Surface covered with long brown setae (densely in humeral part of elytra). Epipleura black, with golden-yellow pubescence on the base.
Ventral side of body covered with dense golden-yellow pubescence.
Legs narrow with femora slightly dilated anteriorly; from blackish-brown to black, densely punctuate, femora with coarse punctures. Tarsomeres and anterior tibia with dense setation, femora with golden-yellow pubescence on the inner and outer sides. Metatarsomere 1 1.3 times longer than length of metatarsomeres 2 and 3 together. Meso- and metatibia and femora with significantly long setae.
Male. Unknown.
Differential diagnosis. Similar species are Oligoenoplus borneanus (Dauber, 2006) comb. nov. from Borneo and Oligoenoplus olivaceosignatus Hayashi, 1979. Oligoenoplus jasarensis sp. nov. in comparison with O. borneanus has a different shape and location of the yellow bands on the elytra; it hasn´t end of elytra covered with golden-yellow pubescence through the full width, while O. borneanus has the full width in end of elytra covered with yellow pubescence (Dauber, 2006: 452, Fig. 22). Compared with O. olivaceosignatus O. jasarensis sp. nov. is. robuster, with a different bands on the elytra and pronotum. O. jasarensis sp. nov. differs also by full width of end of elytra covered with golden-yellow pubescence, while O. olivaceosignatus Hayashi, 1979 has full width of elytra covered with golden-yellow pubescence.
Etymology. Named after the place of discovery, Mt. Jasar.
Distribution. Peninsular Malaysia.
