Description. Male. Head ( Fig. 1 ): eyes separated by 0.5 facet diameter ( Fig. 1 ); interocular suture inverted Y shaped ( Fig.1 ). Antenna: scape cylindrical 2.0X length of pedicel ( Fig. 2 ); pedicel spherical ( Fig. 2 ); flagellum with 14 flagellomeres; all flagellomeres cylindrical ( Figs. 2, 3 ); first flagellomere 1.2X length of second ( Fig. 2 ); apiculus present in flagellomere 14 ( Fig. 3 ); ascoids not visible. Palpus formula = 1.0:2.6:2.4:2.9; last palpomere striated ( Fig. 4 ). Wing ( Fig. 5 ): Sc short; base of R2+3 not attached to R4; radial fork basal; and medial fork complete; R5 ending at wing apex. Male terminalia: hypandrium narrow dorsally with median projection, and ventrally expanded posteriorly with two lateral spines and two arms anteriorly projected ( Fig. 6 ); gonocoxite 0.84X length of the gonostylus with a tuff of bristles along the interior margin ( Fig. 6 ); gonostyli convergent, with pointed apex ( Fig. 6 ); alveoli present along all of the gonostyle surface; epandrium rectangular with one foramen near the anterior margin. Cercopod 1.1X length of epandrium, slightly curved ( Fig. 8 ), with 2 tenacula, one apical and the other subapical ( Fig. 9 ); sternite 10 smaller than tergite 10 ( Fig. 7 ); aedeagus asymmetrical ( Fig. 6 ); with two asymmetrical parameres reaching the level of the aedeagus apex ( Fig. 6 ); aedeagal apodeme the same length as aedeagus, longer than wide, wider anteriorly than posteriorly; gonocoxal apodeme not fused at midline ( Fig. 6 ).

Female ( Fig. 10 ). Similar to male except as follows: apical lobes of subgenital plate of female small, rounded at apex, and separated by a shallow concavity. Cerci blade-like, 2.7X the total length of genital plate from the anterior border at middle to the lobe apices (distance d). Genital complex as illustrated.
