Teredorus parvipulvillus Deng, W.-A., C. Lei & Z. Zheng 2014

Size small, slender. Length of body (from vertex to apex of hind process) 3.8 times as its width (between posterior angles of lateral lobes of pronotum), head distinctly exerted above upper level of pronotum (Fig. 1A). In dorsal view, vertex strongly contracted forward drawing the eyes very near together (Fig. 2A, D), not exserted before eyes, midkeel distinct, extended to occiput; vertex not visible before eyes in lateral view, frontal ridge straight before lateral ocellus, arc-protruding between antennae, longitudinal furrow narrower than width of 1st segment of antennae. Antenna filiform, 15-segmented, inserted between lower margin of eyes (Fig. 2B), mid segments 4-7 times as long as wide. Eyes elevated above the pronotum (Fig. 2B), globular in shape, lateral ocelli placed on slightly lower than middle of anterior margins of eyes (Fig. 2C). Disc of pronotum smooth, with numerous small granules, mid keel of pronotum entire, upper margin of pronotum slightly undulating before shoulders and straight behind shoulders in profile (Fig. 1A). Anterior margin of pronotum straight, lateral keels of prozona short and parallel (Fig. 2D), humeral angle obtuse, without abbreviated carinae between shoulders. Posterior process of pronotum narrow, long cone-shaped, surpassing apex of hind femur and reaching apex of hind tibia (Fig. 1A, B). Lateral lobes of pronotum turned downwards, posterior angles rounded, posterior margin of each lateral lobe with two concavities. Visible part of tegmina ovate (Fig. 2E), apex narrowly rounded, with length 2.5 times its width. Hind wings developed, reaching and slightly surpassing apex of posterior process of pronotum (Fig. 1A). Upper and lower margins of fore femur and mid femur nearly straight (Fig. 2F, G), width of mid femur narrower than width of tegmina (1: 1.4) (Fig. 2E). Hind femur stubby (Fig. 2H), with length 3.3 times its width, mid keel of dorsal and ventral side of hindfemur dentate, antegenicular right angle and genicular denticles acute angle. Outer side of hind tibia with two to three spines, inner side without spine (Fig. 2I). Length of first segment of posterior tarsus longer than third, first pulvillus and third normal, equal in length, apex abtuse; second pulvillus degenerated and very small (Fig. 2J), apex acute. Ovipositor narrow and long, length of upper valvulae 4.2 times its width, upper and lower valvulae with slender saw-like teeth(Fig. 2K). Length of subgenital fig equal to width, middle of posterior margin of subgenital fig triangularly projecting (Fig. 2L). Colouration. Disc of pronotum and head blackish-brown with numerous light marks (Fig. 1A, B). Antennae dark brown (Fig. 2A). Hind wings black. Tergites and sternites black. Outer side of hind femora dark, with white marks; inner side black. Hind tibiae black, with brown at base.
