ZooKeys 464: 99-110. doi: 10.3897/zookeys.464.857 1 Abstract The genus Halolaguna Gozmany, 1978 is studied in China. Two new species, H. flabellata sp. n. from Guangxi and H. discoidea sp. n. from Chongqing, Guangxi and Sichuan are described. The female of H. guizhouensis Wu, 2012 is reported for the first time. Photographs of adults and genitalia are provided. A checklist of all known Halolaguna species is included, along with a key to the Chinese species. Keywords Lepidoptera, Lecithoceridae, Halolaguna, new species Introduction The family Lecithoceridae occurs particularly in the Oriental and Australian Regions, with around 1,200 described species (van Nieukerken et al. 2011). Wu (1997) record- ed 206 species of Lecithoceridae from China and Park et al. (2013) listed 74 species of Lecithoceridae from Chinese Taiwan. To date, approximately 290 species of this family have been reported from China. Halolaguna Gozmany, 1978 is a small genus of the subfamily Torodorinae in Lecithoceridae, which was established by Gozmany in 1978 based on the type species H. sublaxata Gozmany, 1978 from China. Subsequently, Wu (2000) transferred Lecithocera biferrinella Walker, 1864 to Halolaguna, and described H. orthogonia Wu, Copyright Kaijian Teng et al.

To date, Halolaguna includes seven species confined to the Oriental and Palaearctic regions, but little is known about the biology of this genus so far. Halolaguna is characterized by having an elongate and relatively narrow forewing with M, and M, coincident, and the valva tapering to the apex in the male genitalia. Halolaguna is similar to Antiochtha Meyrick, 1905 in both appearance and male geni- talia, but can be distinguished by the presence of M, in the hindwing, which is absent in Antiochtha. It is also similar to Athymoris Meyrick, 1935 in the venation, but differs in the valva in the male genitalia that is tapering to a pointed apex, whereas the valva is foot-shaped and widened terminally in Athymoris. We report five Halolaguna species from mainland China in this paper, based on the specimens collected mostly from mountainous regions and natural reserves. ‘Two species are described as new, and the female of Halolaguna guizhouensis Wu, 2012 is described for the first time. Material and methods The specimens examined in this study were collected from mountains, botanical gardens and nature reserves in China by light traps. All specimens studied, including the types, are deposited in the Insect Collection, College of Life Sciences, Nankai University, Tianjin, China. Genitalia dissections were carried out following Li (2002). Photographs of the adults were taken with a Leica stereo microscope M205A plus Leica Application Suite 4.2 software, and genitalia were photographed using a Leica DM750 microscope plus the same software as for adults.

This species is similar to H. oncopteryx (Wu, 1994) and H. flabellata sp. n. in the forewing shape and the male genitalia, but can be separated from these by the juxta with thin claviform postero-lateral lobes slightly longer than the juxta, and the aedeagus with a discal process apically. In H. oncopteryx (Wu, 1994) and H. flabellata sp. n., the postero-lateral lobes of the juxta are short finger-shaped, about 1/2 length of the juxta, and the aedeagus is absent of discal process apically.

Adult (Fig. 1c) with wing expanse 14.0-15.0 mm. ‘This species is simi- lar to H. sublaxata Gozmany, 1978 superficially by sharing small and rounded discal spot and relatively large fold and discocellular spots. It can be separated from the latter by the valva broadly rounded apically, the relatively short gnathos slightly shorter than the uncus, and the juxta with postero-lateral lobes shorter than the juxta in the male genitalia (Fig. 3c). In H. sublaxata, the valva is narrow and thin apically, the slender enathos is distinctly longer than the uncus, and the postero-lateral lobes of the juxta are longer than the juxta. Female genitalia (Fig. 4b): Eighth sternite bearing dense setae, with caudal margin slightly emarginated at middle. Anterior apophyses about 3/4 length of posterior apo- physes. Ductus bursae about four times length of corpus bursae, long and heliciform; ductus seminalis slender, arising from basal 1/8 of ductus bursae. Corpus bursae nearly rounded; two small papillate signa placed posteriorly, with dense granules; one big rhombic signum placed at middle of corpus bursae, with a nearly triangular horizontal plate arising medially. Distribution. China (Chongqing, Guangdong, Guangxi, Guizhou). Remarks. Halolaguna guizhouensis was described by Wu (2012) based on two male specimens from Guizhou. The valva of this species is not distinctly narrowed distally, whereas the valva of its congeners is obviously narrowed to pointed apex. However, the venation of this species is consistent with that of the type species. The female is described here for the first time.
