Introduction

The Tortricidae fauna of Bhutan is poorly known, with Diakonoff (1977) the only contribution that specifically deals with the family in Bhutan. Based on material collected by the Bhutan expedition of the Basel Museum, he listed six species: Archips termias (Meyrick, 1918), Clepsis rurinana (Linnaeus, 1758), Neocalyptis tricensa (Meyrick, 1912), Epiblema charadrias Diakonoff, 1977, Notocelia zelota (Meyrick, 1916), and Gibberifera simplana (Fischer von Röslerstamm, 1835). Two others were previously described from Bhutan: Archips dispilana (Walker, 1864) and Ulodemis trigrapha Meyrick, 1907. Diakonoff (1941, 1964a, b, 1973, 1976, 1982, 1983, 1984), Meyrick (1907a, b, 1908, 1909, 1912a, b, c, 1914, 1916a, b, 1920, 1921, 1922a, b, 1925, 1927, 1928a, b, 1930, 1931a, b, 1932, 1933, 1934, 1935, 1936, 1937, 1939), Caradja & Meyrick (1937), and Razowski (1968, 1977, 1979, 2006, 2008, 2009, 2012, 2015) described numerous species from India, Nepal, and China, so considerably more information is available from neighbouring countries. In 2016 a small entomological expedition was organized with the goal of collecting moths in Bhutan. This was a joint effort of the National Biodiversity Centre, Serbithang (NBCS), Ugyen Wangchuck Institute for Conservation and Environment (Bumthang), and Naturalis Biodiversity Center, the Netherlands (NBCL). During the field work, 59 specimens of Tortricidae were collected by Cees Gielis and the second author. The material, belonging to the tribes Cochylini, Tortricini, Archipini, Bactrini, Eucosmini, Olethreutini, and Grapholitini, consists of 20 genera and 25 species. A study of that material by the first author is presented here. Together with the six species previously recorded from Bhutan, the total number of Tortricidae species documented from the country is 31.

Material and methods

Moths, including Totricidae, were collected with light traps at numerous locations ranging from 200−500 elevation in the southern part and up to 4000 m in the northern part of the country. Insects were stored in paper bags and dried

526 Accepted by J.W. Brown: 24 May 2019; published: 23 Aug. 2019 for shipping. Subsequently the specimens were relaxed, pinned, and prepared. The genitalia of all species were dissected and mounted on glass slides in Euparal. Photographs of moths were taken with a Nikon D300 camera with a Zeiss Luminar 100 mm lens. Illumination was in a light-box with a full-spectrum tube light. Photographs of genitalia were taken with an Olympus trioculair microscope and a MDC320 digital camera. Forewing length was measured from the wing base to the outermost edge of fringe scales at the apex. Nomen- clature and classification follow the online world catalogue of the Tortricidae (Ver. 3.0). (Gilligan et al. 2014). Holotypes are deposited in the collection of NBC (Serbithang) in Bhutan. The other material is on permanent loan to NBCL.

Thorax (Fig. 11): Forewing length 13 mm; forewing costa sinuate, apex pointed, termen sinuate, dorsum parallel to costa. Markings and colouring in forewing and hindwing the same as described for male. Abdomen: Genitalia (Fig. 61) with papillae anales narrowed posteriorly, distal end truncate; apophyses slender, apophyses posteriores ca. one-half as long as apophyses anteriores, apophyses pos- terior connected ventrally by a band; sterigma broadly triangular, lamella postvaginalis membranous, lamella antevaginalis membranous, bordered by a sclerotized band; ostium small, irregular, U-shaped, colliculum short, with sclerotized lateral bands, rounded distally; ductus bursae long and slender, cestum as long as ductus bursae except for a small area near colliculum; corpus bursae ovoid, signum a large curved horn, capitulum short. Distribution. India, Bhutan. Remarks. This species is newly recorded for Bhutan. Species of Chirapsina have the same venation as those of Archips. Chirapsina is distinguished from Archips by the characteristic long, slender plate of the gnathos and the typical uncus in the male genitalia (Razowski 2009). The genitalia of the specimen examined are similar to those of C. expleta figured in Clarke (1958 : 40). At the same location, a male and a female with markings and colouration similar to C. expleta were collected, and the female genitalia are different from other known Archipini. Hence, it is almost certainly the female of C. expleta and is described and illustrated here for the first time.
