Key to Chaetonerius View in CoL View at ENA , Telostylus and Teloneria , with emphasis on the identification of the species of Teloneria
1. One or two postsutural dorsocentral setae ( Figs 8B View Fig , G–H). Frontal vitta with a median longitudinal groove ( Fig. 7L View Fig , N–O). Tegument shiny, mostly yellow or partially to entirely brown ( Fig. 3 View Fig ). Abdomen homogeneously colored. Wing infuscate on distal third ( Fig. 8 View Fig I–K) ............................... 2 ̄ Four postsutural dorsocentral setae ( Fig. 8D View Fig ).
