Body small and slender. BL 9.9 mm. Body almost blackish brown; mandibles, apex of each femur, and elytra yellowish brown. Body closely covered with brown pubescence.</p> <p>Head slightly shorter than width, dorsum depressed between antennal sockets; eyes relatively large, globular and prominent, interocular distance 2.58 times as wide as the diameter of an eye; mandible arcuate and pointed at apex; each of palpomere with triangular apical segment; antennae reaching 3/5 of elytra, filiform but weakly serrate in basal three segments, comparative lengths of antennomeres as follows: 2.46: 1.00: 1.42: 1.85: 1.79: 1.88: 1.88: 1.85: 1.69: 1.54: 1.81.</p> <p>Pronotum transverse trapezoidal, widest at posterior angles, PW/HW 1.35, PW/PL 1.69, anterior margin weakly emarginate, posterior margin gently protruding in lateral halves and emarginate in the middle, lateral margins almost straight but feebly sinuate in apical 1/4, all angles obtuse and rounded, disc almost flat though provided with a hourglass-shaped convex area in the middle with a medio-longitudinal furrow not reaching the anterior and posterior margins.

Yukikoa nishimotoi sp. nov. is readily distinguishable from all the congeners by blackcoloured head and pronotum. Though the dorsal plate of male genitalia is similar to those of Y. masatakai Takahashi, 2003 from Nagano Pref. and Y. wittmeri (Nakane, 1963) from Ôsaka Pref., the new species differs from them by longer elytra (EL/MEW&gt; 2.0, EL/HEW&gt; 2.7 in Y. nishimotoi; EL/MEW &lt;1.9, EL/HEW &lt;2.6 in Y. wittmeri and Y. masatakai).</p> <p>Distribution. Japan (Honshu, Fukui Pref., Mt. Somayama).</p> <p>Collecting circumstance. According to the collector, the holotype was collected by sweeping large white flowers in the evening.</p> <p>Etymology. The specific name is in honor of Mr. Shôma Nishimoto, who collected the holotype of this remarkable new species.</p></div> 	https://treatment.plazi.org/id/EC0B522DFFD2FE5DFF4EFBC23AF8FE28	Public Domain	No known copyright restrictions apply.
