Frontal sutures indistinct; antennal foramen closed posteriorly. Mouthframe very broadly sclerotized, ferruginous. Frons smooth, testaceous behind front margin; six epistomal setae present. One pair of ocelli present; lens round, strongly convex and partly obscured by sclerotization of gena; pigmented spot indistinct. Hypostoma largely testaceous but broadly and irregularly ferruginous anteriorly; entirely fiat and bearing two to three pairs of setae on each side of gula. Gular region a pale median line. Antenna 3-segmented; segment 3 elongate. Labial palpi with segment 2 about half length of segment I. Mentum distinct from submentum. Prothorax with pronotum entirely smooth, glabrous and pale testaceous on posterior half; sternellum devoid of spicules, asperities and pubescence. Abdomen with each dorsal ampulla bearing two transverse furrows, the posterior one bordered with elongate glabrous tubercles. Tergite 9 bearing a minute, median, vertical, spine-like tubercle near posterior margin, anterior to which is a pair of paramedian, flat, oval, ferruginous sclerotized plates. Anus trilobate. Epipleurum protuberant on all segments. Pleural tubercle with a pair of sclerotized pits which are rather indistinct. Legs absent. Spiracles with peritreme thin, broadly oval and without marginal chambers. Adapted from Duffy (1957).
