Comments. Psyllaephagus kundapurensis  runs to P. mesohomotomae Singh & Agarwal  in the keys given by Singh & Agarwal (1993), Singh (1996) and Hayat (2006). It was compared with the holotype of P. mesohomotomae  but was found to be a distinct species. Some important distinguishing characters are given as follows (characters in bracket are those of P. mesohomotomae  , Figs 27–29View FIGURES 24 – 29. 24 – 26). Female: head in frontal view 2.66 × as wide as frontovertex (3 ×); sculpture on frontovertex and scrobes finely punctate, (frontovertex shallowly reticulatepunctate, smooth and reticulate); scrobes and inter-antennal prominence green with bluish tint (golden green with bronzy hue) and shallow not meeting dorsally (deep and meeting); TED 1 × (1.5 ×) and ITD 1.5 × (2 ×) torular height; scape 3 × (3.5 ×) as long as wide; stigmal vein 1.2 × (1 ×; Singh and Agarwal 1993, fig. 18 G) the combined lengths of marginal and postmarginal veins; basitarsus 1.92 × (1.6 ×) length of middle tibial spur. Male: head 2.12 × (1.5 ×) as wide as high; funicle with setae shorter than (2 ×; Singh and Agarwal 1993, fig. 19 F) width of each segment.
