Tergal lobes of mesothorax pale brown, tergal lobes of metathorax dark brown. Propleura and metapleura light brown, with ochre spots, mesopleura brown. Legs pale brown, coxae and trochanters with ochre spots; tibiae with dark brown areola in setal insertions. Wings hyaline, forewings with pterostigma dark brown, with a large hyaline area distally; a brown marginal band from R4+5 to distal half of 1A; the band shaped like narrow arcs, with hyaline fenestrae on each side of vein ends.

Hypandrium of five sclerites ( Fig. 59 ), central sclerite with tufts of long macrosetae on each side; posterior side sclerites with posterior projection short. Phallosome ( Fig. 61 ) Y-shaped anteriorly, side struts wide basally; external parameres elongate, with rounded apices, bearing small pores. Five endophallic sclerites. Anterior pair medium sized, broadly subquadrate. Lateral sclerites with wide distal area of internal margin convex, bearing teeth. Mesal sclerite transverse, with posterior processes conic, mesal sclerite processes elongate, basally wide, blunt apically; Paraprocts ( Fig. 60 ) oval, setae and spicules as illustrated; sensory fields with 24 trichobothria on basal rosettes.
