Description: body: very small, resembling Paratachys vorax and kin. Elongate semi-ovate; head dark, rest of body mostly pale-fully glossy. Head triangular, face long; mandibles slender, elongate with curved tips, pale yellow; labrum pale, rest of the head dark brown to black. The surface of the head should be smooth with large microsculpture-circular around the centre of the head, then steadily more transverse as one moves away from that region. Eyes not reduced in size, bulging laterally; antennae pale yellow, antennal pubescence beginning on the second half of the first antennomere following the pedicel, or on the second. Pronotum transversely-quadrate; basal margin weakly rounded, hind angles obtuse with one short seta protruding from the angle's apex; lateral margins rounded, very weakly sinuous near the base of the lateral margins; one long seta protruding from both lateral margins just before the front angle; front angles almost acute; front margin curved inward to the pronotal disk. Pronotal disk smooth, glossy pale orange; median line shallow, but visible. The pronotal base should not overlap the elytral base, leaving the scutellum mostly exposed. 7-8 very shallow striae per elytron, all faint or absent, intervals flat; stria 3 should have three evenly spaced, small pits, each with one very short, fine seta within. Most of the elytra is pale yellow-orange, with the apices being marginally dark brown to black. Humeral shoulders round, briefly curving inwards; lateral elytral margins rounded, apices rounded. One small parascutellar pore on either elytron, one on either side of the scutellum. Ventral colouration pale to dark brownish-yellow, legs pale.
