Eumorphobotys uniprotrusus Chen & Zhang , sp. nov. ( Figs 2 View Figures 1–2 , 4–5 View Figures 3–5 )
Diagnosis. This species resembles E. concavuncus Chen & Zhang, 2018 in the appearance and the male genitalia, but can be distinguished from the latter by its pale yellow hindwing and the single triangular protrusion on ventral margin of valva. In the female genitalia, the new species differs from E. concavuncus by the well-developed and strongly sclerotized lamella postvaginalis, the larger corpus bursae and the smaller signum.
Description. Head. Frons brown, with white lateral bands. Vertex pale brown. Labial palpus brown, approximately 2 times as long as diameter of eye; first segment with white scales at base. Maxillary palpus brown. Basal scales of proboscis pale brown. Antenna brown, with pale yellow scales dorsally.
Thorax. Pale brown dorsally and pale ochreous laterally, and white ventrally. Legs yellowish white.
Wings. Wingspan 34.0mm. Forewing straw yellow, with sparse ochreous scales; costa white, posterior margin yellow; orbicular stigma dot-shaped, dark brown; reniform stigma crescent, dark brown; fringe blackish brown, with apex white. Hindwing pale yellow.
Abdomen. Brown dorsally and greyish white ventrally.
Male genitalia ( Fig. 4 View Figures 3–5 ). Uncus short and broad, basal width about 2 times of length; apex concaved medially; distally covered with hairs laterally; both sides of ventral surface extending, forming a lamellar structure. Tegumen trapezoid, slightly wider than uncus. Vinculum U-shaped. Saccus triangular. Transtilla triangular, small, ventral process short. Tongue-shaped valva sharply narrow towards rounded apex; costa weakly curved; ventral margin sclerotized in middle and extended a strongly sclerotized, nearly triangular protrusion, ventral surface densely with short spines, with a heavily sclerotized, thick spine inside it; dorsal sella finger-shaped and barely setose, moderately upcurved; sacculus with an indistinct finger-shaped and excurved process in middle. Juxta large, shield-shaped. Phallus slender, vesica with two sclerotized, finger-shaped cornuti in its distal half, covered with tiny teeth.
Female genitalia ( Fig. 5 View Figures 3–5 ). Ovipositor lobes flat, densely setose. Anterior apophysis about 2.5 times length of posterior apophysis. Lamella postvaginalis well developed and strongly sclerotized, densely spinous, composed of a pair of sclerites with anterior part narrow, oval and posterior part broad, wrinkled. Lamella antevaginalis nearly semi-circular. Antrum cupshaped, short, slightly wider than ductus bursae, sclerotized. Colliculum short, slightly sclerotized. Ductus bursae wrinkled and spiraled, about 2–3 times length of corpus bursae, with base partly sclerotized. Corpus bursae oval; signum small and narrow, maximal length less than 1/4 of length of corpus bursae, ends bearing carinae approximately acute-angled, other two ends slightly produced.
Material examined. Holotype ♂, China: Qinlangdang Conserve Station, Mt. Gaoligongshan , Yunnan, 27.69°N, 98.27°E, elev. 380 m, 30.V.2017, leg. Teng Kaijian et al., genitalia slide no. ZDD12089 ( NKU). Paratype. 1♀, same locality as holotype, 31.V.2017, leg. Teng Kaijian et al., genitalia slide no. ZDD12105 ( SYSBM) GoogleMaps .
Distribution. Yunnan.
Etymology. The specific name derived from the Latin uni - and protrusus, refers to the single triangular protrusion located on ventral margin of valva in male genitalia.
