Zolotuhin & Viktor Sinyaev received 4.XII.2009 Abstract: As a result of a recent expedition undertaken in October-November 2008 in Central Laos by Yu. Bezverkhov and V Sinyaev (both from Moscow) 19 species of the Lasiocampidae, new for Laos, were discovered. Thus, the specific composition of the Lasiocampidae in Laos now rises to 71 species. Kunugia loelagrig spec. nov. from Saysomboune Province, Phou Khao Khouay Nat. Park, 18°54'N, 103°08'E, is described as new. Zusammenfassung: Auf einer Expedition von Yu. Bezverkhov & V. Sinyaev (beide aus Moskau), die im Oktober und November 2008 erfolgte, konnten 19 Lasiocampidae-Arten als neu für Laos nachgewiesen werden. Somit umfaßt der Lasiocampidenbestand in Laos nunmehr 71 Arten. Kunugia loelagrig spec. nov. wird aus dem Phou Khao Khouay Naturschutzpark, Saysomboune Provinz, 18°54'N, 103°08'E, beschrieben. 52 species of the Lasiocampidae were listed from Laos by Zolotuhin & Ihle (2008). During a further expedition, undertaken in October-November 2008 in Central Laos by Yu. Bezverkhov and V. Sinyaev, 19 more species, new for the country, could be disco­ vered. Thus, the specific composition of Lasiocampidae in Laos now consists of 71 species. The species list is given below. As in the previous work, species marked with an asterisk (*) are recorded from Laos for the first time. All specimens listed below are kept in the collection of Yury A. Bezverkhov, Moscow, Russia, but the holotype of the new species will be transferred to the entomological Museum Witt (Munich, Germany). Itinerary and locations of the expedition: 21.

The hindwing with distinct reddish-violet tint in the central area. Wing pattern consists of 4 vague, oblique, straight parallel greyish fasciae, with a darker field between the two central ones. External fascia is weak, greyish to blackish, present as a row of small spots; tornal angle with distinct bluish suffusion. Hindwing is without pattern. In external characters the species is indistinguishable from most other congeners. cf genitalia (fig. 1): Longer and more slender than in other congeners. Tegumen narrow, vinculum cup-shaped. Valvae pyramid-like, with the apex protruded on the top and with a distinct tooth on the inner rib. Distal vinculum processes flattened, with awl-like caudal appendages and two small straddling lumps in sub-basal zone. Aedeagus is short, with wide tubular base, distinct curved apical spur and long sclerotized tube at the base of the vesica. Vesica long tubular, with a single twisted needle-shaped cornutus in basal third by the top of the sclerotized tube; this cornutus is diagnostically directed craniad. Sternum 8 not protruded. Diagnosis: Impossible to separate by external characters from related species (quadrilineata Holloway, 1987; grjukovae Zolotuhin, 2005, and some so far undescribed species from southern Myanmar and Cambodia) but can be easily separated by genitalic struc­ ture where shape of sub-basal straddling lumps on the distal processes of vinculum, shape of valva and characteristic sub-basal twisted craniad cornutus are diagnostic. The only member of this group is known from Laos so far. Bionomics: Rather rare species. The only known specimen was collected in late October at an altitude of 750 m. The 9, preimaginal stages and host plants are unknown. Fig. 1,2: Kunugia loelagrig spec. nov. (1) genitalia of the holotype cf, aedeagus extracted (cornutus marked) and sternum 8, (2) holotype cf. (for fig. 2 in colour, see p. 35.) Distribution: The species is known so far from Laos only. Etymology: This species is dedicated to Helene Grigorieva the mother-in-law of Yury A. Bezverkhov, the collector of the species. She was called ‘grandma Loelya’ by the family, with love and respect. *Metanastria gemella de Lajonquiere, 1979 Ann. Soc. ent.
