| Abstract: | Five of the six valid species of the genus Goniagnathus Fieber known from the Indian subcontinent, namely G. appellans Baker, G. fumosus Distant, G. guttulinervis (Kirschbaum), G. nervosus Melichar and G. punctifer (Walker) are redescribed and illustrated. G. bifurcata Ahmed & Qadeer known from Karachi (Pakistan) is treated here as a junior synonym of G. guttulinervis (Kirschbaum). Four new species, namely Goniagnathus concavus sp. nov., G. quadripinnatus sp. nov., G. symphysis sp. nov., and G. syncerus sp. nov., have been described and illustrated. Three groups of species have been recognised in the genus Goniagnathus; i) the guttulinervis group which includes guttulinervis (Kirschbaum), obfuscatus Linnavuori, parvipictus Linnavuori, albomarginatus Linnavuori and hanifanus Dlabola, ii) the punctifer group including appellans Baker, concavus sp. nov., fumosus Distant, nervosus Melichar, punctifer (Kirschbaum), quadripinnatus sp. nov. and appendiculatus Linnavuori, and iii) the syncerus group including symphysis sp. nov. and syncerus sp. nov. A key to the species of Goniagnathus from the Indian subcontinent is also included. |
