Antennal segments mainly yellow, with faint shadings at apex of IV–VI. Head with occipital carina close to eyes; ocellar triangle without sculpture lines; ocellar setae III close together between posterior margins of posterior ocelli; two or three pairs of postocular setae, median pair long; postoccipital region with transverse narrow reticulation. Pronotum transversely reticulate without internal markings, blotch weakly defined. Mesonotum with closely spaced striations, and small lines between the major striae. Metanotum with linear reticulation, many small linear markings between major sculpture lines. Metasternal anterior margin transverse. Fore wing with distal setae widely spaced, no setae on second vein. Tergites I–VI medially without marginal microtrichia; V–VI with few discal microtrichia medially.
