P. pitambari (Figs 4, 5) can be easily recognized from the two congeneric species known from Thailand by the following characters: areolet of the fore wing absent (Fig. 4) and submetapleural carina not expanded anteriorly into a lobe (Fig. 6). It is distinguished from other species of Phytodietus lacking the areolet by having the first abscissa of Cu 1 shorter than cu-a. P. pitambari is similar in colour to the Oriental species P. namkumensis Kaur et Jonathan but differs in having the occipital carina present (absent in P. namkumensis ) and the distance between 2rs-m and 2m-cu 1.8 times length of 2rs-m (3.4 for P. namkumensis ).


This species has already been recorded in India, Philippines ( Jonathan 1995, Kaur and Jonathan 1979) and Japan ( Shimizu and Watanabe 2015).


P. pitambari has been recorded in: April in Philippines, April and May in India ( Kaur and Jonathan 1979), May, July, August in Japan ( Shimizu and Watanabe 2015), and the beginning of August in Thailand suggesting that it has more than one generation per year. It has been noted at an altitude of 1228 and 610 m a.s.l. in India, and 455 m a.s.l. in Philippines ( Kaur and Jonathan 1979). In Thailand P. pitambari was collected at 700 m a.s.l. in a mixed deciduous forest with Dipterocarpus sp., Lagerstroemia sp., Pterocarpus macrocarpus Kurz, Terminalia sp. and Xylia xylocarpa (Roxb.) Taub. being the dominant tree species and various grasses including i.a. Imperata cylindrica (L.) and Chrysopogon zizanioides (L.) in the shrub layer. No hosts are currently known.
