Diagnosis. Belonging in species group “1”, subgroup 1 in the classification of Eertmoed (1986). Forewings with spur veins, epiproct emarginate posteriorly ( Fig. 20 ). Unlike the other species in the genus, it has the paraproctal prong with a denticulate process on the inner margin ( Fig. 21 ).

Color. Head ( Fig. 17 ) brown to dark brown, vertex, labrum and mandibles brown, maxillae pale brown, labium cream. Compound eyes dark brown, ocelli hyaline in a dark brown area. Antennae and maxillary palps pale brown, flagellomeres cream apically. Pro-, meso- and metanotum pale brown; thoracic pleura and legs pale brown, tibiae and tarsi darker. Forewing membrane hyaline ( Fig. 15 ); with slightly smoked small areas; veins brown, with pale brown spots along the veins; wing margin with brown spots. Hindwings hyaline ( Fig. 16 ). Abdomen pale brown to cream, incomplete abdominal segmental rings pale brown, clunium and hypandrium brown; phallosome and epiproct pale brown; paraprocts brown, paraproctal prong dark brown.

Morphology. As in diagnosis plus the following: head vertex emarginate, at the same level of the upper margin of the compound eyes ( Fig. 17 ); these large, with interommatidial setae. D is 0.52 the length of the head in front view. Forewings ( Fig. 15 ) with spur veins, membrane pterostigma with setae. Hypandrium semioval, broad, emarginate posteriorly, with medium sized setae and macrosetae. Phallosome piriform, widened distally, endophallic lobes broad, rounded apically, and separate from each other along the midline; internal parameres club shaped ( Fig. 19 ). Epiproct semioval, emarginate posteriorly ( Fig. 20 ), with three macrosetae and two setae mesally, posterior setal field as illustrated. Paraprocts ( Fig. 21 ) with medium sized setae and macrosetae on long, stout mesal process as illustrated; mesal prong stout, well sclerotized, with jagged sclerotized process on the inner border; sensory fields with 18 trichobothria on basal rosettes ( Fig. 21 ).
