Diagnosis : Lithocharodes puncticeps is most similar to light specimens of L. nigripennis in size, colouration and punctation of the head. The distinguishing characters are listed there. Description : Length: 4.7 mm . Colouration: Brown; pronotum light yellow-brown; elytra darker than pronotum with lightened posterior angles; legs and antennae light brown. Head: 0.76 mm long, 0.61 mm wide; elongate; eyes small; postocular sides 2.7 times as long as eyes; approximately parallel; posterior angles widely rounded; posterior margin shortly straight in front of neck; setiferous punctation dense and deep; on average, interstices between punctures half as wide as diameter of punctures; anteriorly partly coriaceous; interantennal furrows moderately deep; reaching anterior third of eyes; wide midline impunctate; surface without microsculpture; glossy. Antennae with first antennomere half as long as head; second and third antennomere conical; longer than wide; subsequent antennomeres wider than long and increasing in width; fourth antennomere nearly twice as wide as long; tenth antennomere slightly more than twice as wide as long; all antennomeres distinctly pubescent. Pronotum: 0.81 mm long, 0.61 mm wide; widest in anterior third; anteriad, conically narrowed toward neck; distinctly narrowed in middle third; slightly convergent in posterior third; setiferous punctation as deep as on head but much sparser; on average, interstices between punctures as wide as diameter of punctures or partly wider; wide midline impunctate; irregular line of punctures adjacent to midline with 9-10 punctures; surface without microsculpture; glossy. Elytra: 0.84 mm long, 0.69 mm wide; humeral angles sub-rectangular; sides nearly parallel posteriorly; posterior angles sub-rectangular; posterior margin slightly convex; short incision at suture; setiferous punctation even sparser than on pronotum; on average, interstices twice as wide as diameter of punctures; surface with weak isodiametric microsculpture; less shiny than head and pronotum. Abdomen with dense but weak setiferous punctation; surface with isodiametric microsculpture; as shiny as on elytra; posterior margin of sternite VII of male with wide medial prominence; posterior margin of tergite VII of male convex with short medial incision. Mesotibia with one, metatibia with two subapical ctenidia. Aedeagus oval; small; endophallus short, with minute teeth and few slightly larger but still minute teeth in between; paramere slender; slightly curved to nearly acute apex; with few, fine setae.
