description: <b> <i>Pissodes punctatus</i> Langor and Zhang 1999</b> (Figs. 11, 13, 14–22) <i>Pissodes punctatus</i> Langor and Zhang, in Langor <i>et al.</i> 1999: 595 <b>Diagnosis.</b> Larvae of <i>P. punctatus</i> may be separated from those of other known <i>Pissodes</i> species by the following combination of characters: head unicolorous to possessing pale area on central 0.25 or more of dorsal surface that is lighter in color than remainder (Fig. 14); antenna with a conspicuous, elongate sensorium, as long as wide at base or longer, with truncate apex (Figs. 14, 16); occipital foramen without ventral apodemes, curvature of foramen continuous (Fig. 17); pigmentation of pronotum pale, most specimens with pigmentation present on mediodorsal ¼ to ½ of sclerite, rarely present only as a faintly pigmented stripe near anteromedial margin (Fig. 11); prodorsum of abdominal segments with posterior margin medially emarginated, prodorsum lens-shaped, bi-convex (Fig. 13). <b>Description.</b> Similar to <i>P. yunnanensis</i> except as follows: Color light brown, most specimens with central 0.25–0.33 of dorsal surface of head capsule with a pale area on the posterior portion of the frons and either side of epicranial suture, rarely unicolorous or with faint stripes around des1 (Fig. 14). Side of head capsule with anterior end of pale stripe directed around les1 and toward les2 (Fig. 16). Head capsule oval, width/length in anterior view 1.00–1.04 (Figs. 14, 17); posterior margin in lateral view with middle quarter slightly convex to flat (Fig. 16). Endocarina covering 0.7–0.8 of distance between epicranial suture and epistoma (Fig. 14). Posterolateral margin of occipital foramen with elongate triangular, rounded postoccipital condyle; occipital foramen somewhat quadrate, with dorsal half less concave than ventral half to nearly straight, widest point near ventral margin; ventral apodemes lacking, foramen curvature in ventral half continuous (Fig. 17). Setae des1 and des2 at head capsule mid-length, des3–des5 on lateral third of margin of frontal suture; des3 and des 5 in near proximity and relative distant from des4 (Fig. 14). Seta les1 about 0.6 as long as les2; setae separated by about the length of les2; les2 close to anterior margin of head (Figs. 14, 17). Labrum width/length about 1.5 (Fig. 18); apex with als1–als3 present; ams longer than als1–3, some specimens with a supernumerary minute ams present (Fig. 19). Postmentum membranous, with an irregularly elongate-oval pigmented area on each side of premental sclerite; pigmented areas slightly depressed, and slightly sculptured in some specimens (Fig. 20). Pigmentation of pronotum pale, most specimens with pigmentation present on mediodorsal ¼ to ½ of sclerite, rarely present only as a faintly pigmented stripe near anteromedial margin (Fig. 11). Pleurum fused to lateral margin of pedal area, represented by setose area; area large, broadly to irregularly oval, smooth, bearing long setae, devoid of microtrichia. Pedal area ovoid, unpigmented to slightly pigmented, slightly convex and with a distinct margin in most specimens, lacking microtrichia, larger than pleural sclerite. Meso- and metathorax with pedal area slightly convex and with distinct margin in most specimens. Pedal area with 6 setae, posterior about 0.66 as long as longest pleural seta, remainder shorter; pedal area plus pleurum broadly oval, narrower near midline than laterally, sclerite irregular oval, unpigmented, detectable only by absence of microtrichia. Abdominal segments I-VII with prodorsum lens-shaped and apically acute, with posterior margin slightly concave, groove separating it from anterior segment slightly obscured laterally (Fig. 13); prodorsum as long as both sections of postdorsum on midline, with posterior margin slightly concave, groove separating it from anterior segment slightly obscured laterally; prodorsum slightly shorter than both sections of postdorsum on midline (Fig. 13); spiracular area oval, with anteroventral depression not to lightly pigmented, merged with deep groove between postdorsum and epipleurum. Abdominal segment IX with dorsum separated from pleurum by a distinct groove (Figs. 21, 22). Abdonimal segment X with dorsal lobe lightly larger than lateral lobes. <b>Material Examined.</b> China.
