Mukaria striola Zhao, Luo & Chen sp. nov.

Figs. 12–22 , 24, 29–32

Body length: male: 3.9–4.2 mm, female: 4.0– 4.3 mm.

Coloration. Body is black. Crown black ( Fig. 12 ). Frontoclypeus with a bright yellow rounded spot in basal middle region ( Fig. 16 ). Ocellus yellow, eye brownish black ( Fig. 15 ). Pronotum with three yellow stripes in anterior, middle and posterior margins, scutellum dark ( Fig. 14 ). Forewings with bright yellow irregular stripes except telocellular area. External margin of forewing with a transparent spot near the terminal part ( Figs. 12, 13 ).

Head and thorax. Crown moderately extended forward, midlength about 0.3 times inter ocular width (1:3.88) ( Fig. 14 ). Ocellus located at lateral margin of crown ( Fig. 15 ). Face including eyes 1.5 times as wide as long (1.51:1); base of frontoclypeus plump, the middle part is mostly flat; lorum with wrinkles on the surface ( Fig. 16 ). Pronotum transversely broad, subequal to head width (1.07:1) ( Fig. 14 ). Forewing length about 4 times as long as the widest part (3.98:1) ( Fig. 12 ).

Male genitalia. Pygofer transversely broad, dorsal part with attenuate and long bristles, ventral margin with a thick and long spine curved toward base in middle with tip spiculate ( Fig. 18 ). Valve trapezoidal, subgenital plate narrow the base, broad at the middle and densely small setose laterally ( Fig. 22 ). Style apex fingerlike pointing outward obliquely, constricted with many small tiny hairs in middle ( Fig. 21 ). Connective and aedeagus fused, aedeagus stout at base, separated into two branches in 1/3 of base, both branches slanted and slender, apex spiny, curved toward base ( Figs. 19, 20 ).

Female genitalia. Sternite VII is about 3.4 times as wide as long, with nearly straight anterior margin, concave posterior margin, and lateral margins tapered posteriorly ( Fig. 24 ). Valvula I similar to Mukaria creagra sp. nov. Valvula II more sparsely toothed ( Figs. 31, 32 ).

Material examined. HOLOTYPE: ♂, China: Yunnan, Xishuangbanna Dai Autonomous Prefecture, Mengla County, Menglun Town (21°93’N, 101°25’E), 27 September 2015, collectors: Zhengxiang Zhou, Qiang Luo, paratypes: 4 ♂♂, China: Yunnan, Xishuangbanna Dai Autonomous Prefecture, Mengla County , Menglun Town (21°93’N, 101°25’E), 27 September 2015, collectors: Zhengxiang Zhou, Qiang Luo. 6 ♂♂ 6♀♀, China: Yunnan, Xishuangbanna Dai Autonomous Prefecture, Mengla County , Mohan Town (21°46’N, 101°56’E), 2 September 2017, collectors: Nian Gong, Qiang Luo, Yan Zhi.

Distribution. China (Yunnan).

Host Plant. Bamboo.

Etymology. The name is the Latin noun ‘striola’ means ‘striated’ and refers to the pronotum and forewings covered with yellow stripes.

Remarks. The new species is most similar to M. albinotata Cai & Ge, 1996 , but differs as follows: (1) pronotum and forewing of new species with yellow stripes (shiny black in latter); (2) pygofer of new species with a long protrusion curved toward the end in lateral view (latter with a long protrusion curved toward the base); (3) aedeagus of new species starts branching from the 1/3, with both branches end acute toward the base (aedeagus of latter starts branching from the base, with the tip split into two lamellar processes, one pointing to base and other to apex).
