Abstract
The present study entitled “The Lamiinae (Coleoptera: Cerambycidae) of southern India” was carried out at College of Agriculture, Vellayani during 2015 to 2020 with the objectives of collection and identification of the flat faced long-horned beetles (Lamiinae) of southern India, preparation of descriptions and illustrated key to species, with emphasis on characters of male and female genitalia and documentation of host plants in all possible cases. The specimens were collected using different methods viz., hand picking, sweep netting, light traps, jackfruit twig trap and rearing from the infected plant parts. The specimens were processed following the standard procedures. Similarly, dissections, photographs and illustrations were prepared. Details of the specimens examined and the measurements of different body parts including that of male and female genitalia are included under each species. All the species included in the present study were identified using available literature. Taxon descriptions were prepared by considering all the morphological variations and also including the variations of male and female genitalia wherever available. A checklist of the species and illustrated key to the genera documented in the present study are also provided. Present study has generated taxonomic and ecological information on the Lamiinae fauna of south India. Sixty six species belonging to 41 genera of south Indian Lamiinae were studied. Detailed descriptions and illustrations, including that of male and female genitalia, are provided. Species-wise distribution and host plant data are furnished wherever available. Ecological information is also provided for a few of the species. Descriptions of two new species, Miccolamia ferruginea and Notomulciber viraktamathi were published. These include species descriptions, key to Indian species of the respective genera and a discussion on the need for redefinition of the respective subgenera. Description of the male of Monochamus shembaganurensis, with additional information on its distribution, was published. Four new species were recognised, one each belonging to the genera Eunidia and Falsoropica and two of Glenea. New distributional and ecological data are furnished for Acalolepta tenuipes, Agelasta quadrimaculata, Apomecyna saltator, Apriona trilineata, Batocera rufomaculata, Coptops aedificator, Epepeotes uncinatus, Eucomatocera vittata, Eunidia bicolor, Eunidia variegata, Eunidia simplex, Exocentrus (Camptomyne) vittatus, Hirtaeschopalaea albolineata, Macrochenus tigrinus, Nupserha bicolor, Olenecamptus bilobus, Phelipara indica, Sthenias grisator, Sybra praeusta, Thylactus angularis, Zotalemimon posticatum and Zotalemimon procerum. Among the south Indian Lamiinae, Apomecyna saltator, Batocera rufomaculata, Celosterna scabrator, Cleonaria bicolor, Coptops aedificator, Glenea multiguttata, Nupserha bicolor, Olenecamptus bilobus, Sthenias grisator and Sybra praeusta are well known pestiferous species. There are many Lamiinae still awaiting discovery and formal naming. Hence, studies encompassing the different ecozones of the country are sure to add several new species of flat faced longhorned beetles to the Indian fauna. Many species are known only by original descriptions based on a single specimen. Hence, there is an urgent need for intensive studies to generate information on their natural history. Future studies should concentrate on revising and updating the taxonomy of Lamiinae of economic importance so as to develop effective IPM programmes. To promote and facilitate studies on biodiversity and conservation of the native fauna of longhorned beetles, there is an urgent need to digitalize the type specimens of Indian Cerambycidae deposited in several European natural history museums besides developing a database with interactive keys for easy identification. The future taxonomic works on Indian Cerambycidae should also aim for Phylogeny of Indian fauna based on integrative taxonomy.
