Comments.

The synonymy of Paratelenomus longus (Kozlov & Lê) is based on photographs of the holotype specimen provided by Talamas and Pham (2017) ( Figs 18-21 ) and images of the holotype of P. tetartus provided by Talamas et al. (2017) ( Fig. 17 ). The mesopleuron on the holotype of P. longus is obscured by its foreleg and by glue ( Fig. 19 ), making it impossible to confidently assess the characters of couplet 3 in the identification key of Johnson (1996). However, we can exclude the species that follow the first lead of the couplet because this specimen has microsculpture throughout the mesoscutum and mesoscutellum, well-developed submedian carinae on the frons, and T1 is xanthic and distinctly contrasting in color with the following metasomal segments. This combination of characters is not found in P. angor Johnson ( Figs 28 , 29 ), P. matinalis Johnson ( Figs 30 , 31 ), or P. striativentris (Risbec) ( Figs 32 , 33 ). Following the second lead of the couplet results in an identification of P. tetartus , which matches the visible morphology and collection locality of P. longus .

Treatment of P. mangrovus as a junior synonym follows reexamination of the holotype of this species and reevaluation of the characters used by Rajmohana & Narendran (2007) to separate it from P. tetartus . Specifically, the length of the orbital carina and the proximity of the cells of the postacetabular and mesopleural epicoxal sulci are variable. The lateral habitus image of the holotype of P. mangrovus ( Fig. 26 ) does not illustrate the presence of 4-5 episternal foveae, but instead illustrates the presence of 4-5 foveae immediately dorsal to the mesopleural carina, which is known to exist in P. tetartus ( Fig. 27 ).
