( Figs 29–35 )

Diagnosis. Belonging in species group “2”, subgroup 4, in the classification of Eertmoed (1986). Differing from the other species in the subgroup by having the epiproct with a broad median projection, distally emarginate, with lobes on each side ( Fig. 34 ); paraproctal prong short, tapered, curved distally and proximally wide ( Fig. 35 ).

Color. Head ( Fig. 31 ) brown, vertex dark brown; labrum, mandibles, labium and maxillae pale brown. Compound eyes dark brown, ocelli hyaline in a dark brown area. Antennae and maxillary palps pale brown. Pronotum, mesonotum and metanotum pale brown, darker medially, thoracic pleura and legs pale brown to cream, tibiae and tarsi darker. Forewing membrane hyaline ( Fig. 29 ); veins pale brown, with brown spots along the veins, vein ends and areola postica at wing margin. Hindwings hyaline ( Fig. 30 ). Abdomen cream, clunium and hypandrium pale brown, clunium with narrow anterior border dark brown; epiproct cream; paraprocts pale brown, paraproctal prong darker distally.

Morphology. As in diagnosis plus the following: head vertex emarginate, almost at the same level of the upper margin of the compound eyes ( Fig. 31 ); these large, D is 0.51 the length of the head in front view; with interommatidial setae. Forewings ( Fig. 29 ); membrane pterostigma with setae, without spur veins. Hypandrium triangular, broad, with medium sized setae and macrosetae ( Fig. 32 ). Phallosome narrow anteriorly, with anterolateral corners projected; wide distally, external parameres rounded laterally; endophallic lobes broad, rounded apically, touching each other along the midline; arms of internal parameres bow shaped, the posterior ends close to each other in the midline ( Fig. 33 ). Epiproct trapeziform ( Fig. 34 ), with three macrosetae, one setae mesally and other macrosetae near each postero-lateral corner, posterior setal field as illustrated, posterior projection with four setae on apical margin. Paraprocts ( Fig. 35 ) with medium sized setae and macrosetae as illustrated; mesal prong stout, short, broad proximally; sensory fields with 16 trichobothria on basal rosettes ( Fig. 35 ).
