Abstract A new species Clistopyga ghatensis sp. nov. is described from the Western Ghats. C. ghatensis sp. nov. differs from the only other known Indian species C. sziladyi Kiss in having wrinkles on propodeum and discoidella of hind wing absent. C. ghatensis sp. nov. differs from C. longifemoralis Varga and Reshchikov from Thailand in having coarsely punctate face and hind femur as long as hind tibia. A key to Oriental species is provided.

Introduction Cerambicidae) recorded from France, Russia, England and Austria (Thompson, 1957). In this study, we describe a new Clistopyga Gravenhorst is comparatively large sized genus species of Clistopyga viz., C. ghatensis sp. nov., from the comprising of 49 species worldwide (Yu et al., 2012; Western Ghats in India. This is the second record of the Varga and Reshchikov, 2015; Bordera et al., 2016). Three genus from Western Ghats. This new species does not fit to species have been previously recorded from the Oriental the keys or description of any known species of Clistopyga. region viz., C. latifrontalis Uchida recorded from China, C. sziladyi Kiss from India, and C. longifemoralis Varga and Materials and Methods Reshchikov from Thailand. Clistopyga species are rare in collections, also hard to collect using Malaise trap or Sweep The material examined in the present paper is collected net methods (Bordera et al., 2014). Some of the noteworthy from Kalakkad Mundanthurai Tiger Reserve (KMTR) in publications regarding the species of Clistopyga are that of the Southern Western Ghats. The Tiger Reserve is located Kiss (1933), Uchida (1941), Kusigemati (1984, 1985), Varga in South Indian state of Tamil Nadu, with a total of 895 and Reshchikov (2015) and Bordera et al.,(2016). Varga km2, is considered one of the centres of biodiversity and and Reshchikov (2015) synonymised C. nagatomii with C. endemism in India by IUCN. Morphology was studied sziladyi. Very little information is known about the biology using Olympus binocular stereozoom microscope of Clistopyga and no host record has been reported so far and photographs taken by using Leica Stereozoom from the Oriental region. C. rufator was reared in England microscope M205A model with an attached camera DMC from the nest of Clubiona juvenis Simon in curled dead 2900. Morphological terminology employed in this study Phragmites leaves (Fitton et al., 1988). They are associated follows Townes (1969) and Wahl and Sharkey (1993). with spiders as in Polysphincta group. Different hosts of The type specimen is deposited at Prof. T.C. Narendran Clistopyga includes Anthonomus pyri Kollar (Coleoptera: Biodiversity Research Laboratory for the time being and Curculionidae), Cynips kollari Hartig (Hymenoptera: will be transferred to Western Ghats Regional Centre Cynipidae), Ryacionia buoliana Schiff (Lepidoptera: Zoological Survey of India, Kozhikode.
