Lepidozonates tenebrosellus Park, 2013

( Figs 4 , 11 , 14, 14a )

Lepidozonates tenebrosellus Park, 2013: 224 . TL: Thailand. TD: MGCL.

Material examined. CHINA, Yunnan: 1♂ 1♀ , Mt. Jinuo, Jinghong , 1003 m, 30.VII.2019, leg. KJ Teng, C Liu & AL Wang, slide Nos. YS 20141♂, YS20193 ♀; 2♀, Yexianggu, Xishuangbanna , 762 m, 17–18.VII.2014, leg. KJ Teng et al., slide No. YS 20283 .

Adult ( Fig. 4 ). Wingspan 18.0–21.0 mm.

Female genitalia ( Fig. 14 ). Apophyses posteriores about 1.5 times length of apophyses anteriores; apophyses anteriores with a small ramification at basal 1/3. Antrum membranous except posterior margin sclerotized and roundly produced medially. Ductus bursae slightly longer than twice length of corpus bursae, twisted anteriorly, weakly sclerotized in posterior 1/5, membranous in anterior 4/5, dilated at posterior 1/4, with dense spines posteriorly and sparse spines medially; ductus seminalis slender, arising from about posterior 2/5 of ductus bursae, with dense denticles on inner wall ( Fig. 14a ). Corpus bursae elliptical, granulose; signum rounded, serrate along margins, with a rectangular, denticulate median groove.

Abdomen: Female eighth abdominal sternite concave at middle on posterior margin.

Diagnosis. This species is similar to L. landryi , but it can be distinguished by the black forewing, and in the male genitalia by the flap from the dorsal surface of the juxta shorter than the juxta, and the aedeagus as long as the valva ( Fig. 11 ); in the latter species, the forewing is yellowish brown, the flap is longer than the juxta, and the aedeagus is shorter than the valva. It is also similar to the new species, L. semiovatus sp. nov., and the differences between them are stated in the diagnosis of the latter species.

Distribution. China (Yunnan), Cambodia, Thailand.

Remarks. The specimens examined in this study have a longer wingspan (18.0–21.0 mm) than the wingspan of the type series (14.0–15.0 mm). This species is newly recorded in China, and its female is described for the first time.
