Hemilea sp. nr. cnidella Munro, 1936 ( fig. 18 )

Material. Thimphu, 3 km NNE Dochula , 27.518° N, 89.755° E, 2360 m, 19.08.2017, hand collecting, 2 Ơ

(M. Hauser leg.) FFP 17BT065 ( CSCA 19L110).

D i s t r i b u t i o n. Bhutan (first record of the genus).

Note. The specimens on hand belong to the group of Oriental species with a uniformly rufous yellow mesonotum and widely black abdominal tergites, which includes H. bipars (Walker, 1852) , H. praestans ( Bezzi, 1913) , H. formosana Shiraki, 1933 , H. cnidella Munro, 1936 , and H. quadrimaculata Hancock & Drew, 1995 . The dark wing pattern is slightly more extensive in cell dm than in H. praestans and more extensively hyaline in cells dm and m 1 than in H. quadrimaculata , and better fits the patterns of H. bipars and H. formosana , but the latter two species have abdominal tergites either entirely black or at most with syntergite 1+2 brownish-yellow, whereas in the specimens from Bhutan tergites 3–5 have a yellowish medial incision narrowing posteriorly, as in H. cnidella . The specimens from Bhutan differ from the latter species by having the dark wing pattern in cell dm wider posteriorly, with a pale brown lobe extending into cell m 4 (= cua 1).

Oriental species of Hemilea are rare in collections; they need a comprehensive taxonomic revision based on more extensive material collected throughout the Oriental Region to evaluate variability of the wing and abdominal pattern and to provide identification of species based on study of male and female terminalia. Shapes of the aculei are very informative in most genera and species of the Trypetini , and their examination, along with molecular studies could solve the problem of identification of species assigned to Hemilea .
