Keys to the South Indian species of Tibiaroliate assassin bugs (Heteroptera: Reduviidae)

Keys to 52 species belonging to 10 genera and 5 subfamilies of the tibiaroliate group of Reduviidae recorded in southern India have been formulated. Morphology of the antennae, rostrum, frons, ocelli, pronotum and scutellum were considered while devising the keys. The species included in these subfamilies were (i) subfamily Acanthaspidinae, genus Acanthaspis Amyot & Serville: A. carinata Murugan & Livingstone, A. minutum Livingstone & Murugan, A. pedestris Stal, A. siruvanii Livingstone & Murugan, A. nigripes Livingstone & Murugan, A. flavipes Stal, A. alagiriensis Murugan & Livingstone, A. angularis Stal, A. quinquespinosa Fabricius, A. apicata Distant, A. siua Distant, A. rugulosa Stal, A. trimaculata Reuter, A. rama Distant, A. sexguttata Fabricius, A. tergemina Burmeister; genus Edocla Stal: E. slateri Distant, E. maculatus Murugan & Livingstone, E. heberii Murugan & Livingstone, E. punctatum Murugan & Livingstone; (ii) subfamily Ectrichodiinae, genus Ectrychotes Burmeister: E. pilicornis Fabricius, E. dispar Reuter, E. abbreviatus Reuter, E. atripennis Stal, E. bharathii Murugan & Livingstone; genus Haematorrhophus Amyot & Serville: H. marginatus Reuter, H. fovealis Murugan & Livingstone, H. nigroviolaceus Reuter, H. pedestris Distant, H. ruguloscutellaris Murugan & Livingstone, H. tuberculatus Stal; (iii) subfamily Salyavatinae, genus Nudiscutella Murugan & Livingstone: N. frontispina Murugan & Livingstone; genus Petalochirus Pal: P. burmanus Distant, P. brachialis Stal; genus Lisarda Stal: L. longispina Distant, L. annulosa Stal; (iv) subfamily Piratinae, genus Ectomocoris Mayr: E. quadriguttatus Fabricius, E. tuberculatum Livingstone & Murugan, E. nigrochripes Murugan & Livingstone, E. tibialis Distant, E. horridus Kirby, E. cordiger Stal, E. cordatus Wolff, E. gangeticus Fabricius; genus Pirates Stal: P. quadrinotatus Fabricius, P. affinis Serville, P. punctum Fabricius, P. unipunctatus Livingstone & Murugan, P. atromaculatus Stal, P. lepturoides Wolff; and (v) subfamily Triatominae, genus Linshcosteus Distant: L. confumus Ghauri and L. costalis Ghauri. Fifteen new species were added by the authors to the tibiaroliate Reduviidae of Southern India.
