Lithocharodes germana SHARP, 1885: 492

Type material examined: male, holotype: Guatemala ,

San Jéronimo, leg Sallé ( BMNH).

Diagnosis: Regarding the colouration and the punctation of the head, L. germana resembles L. collaris . But L. germana is distinctly larger than L. collaris and the eyes are smaller. The postocular sides are three times as long as eyes in L. germana but only twice as long as eyes in L. collaris .

Description: Length: 6.3 mm. Colouration: Brown; head dark brown to nearly black; elytra slightly lighter brown.

Head: 0.87 mm long, 0.69 mm wide; sides divergent posteriad; eyes short; postocular space three times as long as eyes; posterior angles sub-rectangular; interocular furrows moderately deep and slightly curved; nearly reaching posterior edge of eyes; in front of neck with indistinct dorsal depression; setiferous punctation deep; moderately dense and evenly distributed except wide impunctate midline; on average, interstices as wide as diameter of punctures; space between interocular furrows impunctate; surface without microsculpture; shiny. Antennae with first antennomere as long as half-length of head; second and third antennomere conical; longer than wide; subsequent antennomeres increasing in width and wider than long; fourth antennomere twice as wide as long; tenth antennomere nearly three times as wide as long; all antennomeres pubescent; fourth to eleventh antennomeres with denser pubescence. Pronotum: 0.78 mm long, 0.61 mm wide; widest in anterior third; anteriad conically narrowed toward neck; narrowed in middle third; nearly parallel in posterior third; setiferous punctation deep and moderately dense, except for wide impunctate midline; adjacent to midline with irregular line of 14-15 punctures; surface without microsculpture; shiny. Elytra: 0.84 mm long; 0.68 mm wide; sides nearly parallel; humeral angles and posterior angles rectangular; posterior margin slightly retreated toward suture; setiferous punctation deep and dense; on average, interstices between punctures as wide as or slightly shorter than diameter of punctures; surface with weak, isodiametric reticulation; matt; less shiny than head and pronotum. Abdomen with dense setiferous punctation; with net-like reticulation; as matt as elytra; tergite VII of male with triangular emargination and tooth-like, prominent outer angles; sternite VII without peculiarities. Meso- and metatibia with two subapical ctenidia each. Aedeagus approximately oval, without distinct anterior angles; endophallus large, internal sack posteriorly recurved, covered with minute teeth; one short string with few large teeth; second more transparent, long string with medium sized teeth; paramere straight at base and abruptly curved at apex; with numerous setiferous punctures.
