Description of holotype (male). Dorsum ( Fig. 1 View FIGURES 1–3 ). Body length 2.9 mm, elongate, robust, shiny, reddish brown, glabrous.

Head ( Fig. 10 View FIGURES 10–16 ) relatively large, broad, trapezoidal, convex, in posterior half shiny, without microreticulation; in anterior half matt, with distinct microreticulation; with relatively dense, low but distinct tubercles in anterior half. Clypeus with margin bordered, distinctly sinuate anteriorly, widely rounded laterally, not notched before genae, clypeal border without macrosetae. Genae obtuse, weakly exceeding eyes, without macrosetae. Frontal suture not noticeable, without gibbosity. Punctation of clypeus double in posterior half, fine and coarse; all punctures quite dense, irregularly distributed, variable in size; in anterior half punctation simple, fine, quite dense, irregularly distributed.

Epipharynx ( Fig. 14 View FIGURES 10–16 ) transverse, with sides rounded, anterior concavely arcuate, without corypha with two very short, thick celtes in the middle. Acanthopariae, acropariae, prophobae without chaetae. Chaetopariae with belt of dense, long, thick chaetae; adelochaetae similarly like chaetopariae but shorter; chaetopedia with dense belts of thick chaetae, as long as adelochaetae. Epitorma not observed. Tormae thin, quite long.

Pronotum transverse, posteriorly approximately as wide as base of elytra, widest at posterior lobe, convex, shiny, without microreticulation, with double punctation; larger punctures variable in size, four to six times larger than smaller, dense, quite regularly distributed; smaller punctures dense, quite regularly distributed. Margins without macrosetae; posterior margin bordered by a groove covered by dense, coarse punctures; anterior margin not bordered; lateral margins bordered only near hind angles, on explanate surface. Anterior and posterior angles weakly divergent; sides near hind angles with small but distinct tooth anterior to emargination in addition to a basal tooth; margin between teeth very weakly sinuate in dorsal and lateral view ( Figs. 20, 23 View FIGURES 17–26 ).

Scutellar shield small, triangular, with ogival sides, without punctures, shiny, without microreticulation.

Elytra with complete, broad basal groove, elongate, convex, weakly widened posteriorly, shiny, without microreticulation, without macrosetae; without humeral denticles; with 10 striae and 10 intervals. Striae distinctly, densely punctate with medium sized, “8”-shaped punctures; punctures very gently indenting margins of intervals. All striae slightly shortened before apex, eighth and ninth shortened before base. Intervals shiny, evenly convex, with quite regularly distributed, simple, fine punctation along middle. Surface of the humeral callus ( Fig. 17 View FIGURES 17–26 ) shiny, with only a trace of microreticulation, with very sparse fine punctation.

Legs. Profemora bordered anteriorly and posteriorly, very weakly shiny, with dense, very irregularly distributed, sparse punctation; mesofemora and metafemora bordered only posteriorly, shiny, without microreticulation, finely and sparsely punctate. Protibiae distinctly tridentate laterally, basal most tooth further from middle tooth, than middle tooth is from apical tooth, lateral edge not serrulate basally; dorsal surface smooth, shiny, with few fine punctures bearing long macrosetae; apical spur long, moderately broad, gently downwardly and outwardly bent, with acute apex. Mesotibiae and metatibiae without transverse carinae, fimbriate apically with row of short spinules of unequal length. Apex of metatibiae without accessory spine. Metatibiae superior apical spur slightly longer than basal metatarsomere, latter nearly as long as the next three metatarsomeres combined. Claws very small, short, thin, gently arcuate.

Macropterous.

Venter ( Fig. 2 View FIGURES 1–3 ). Metaventral plate shiny, flat, with distinct, deep, wide longitudinal line at middle; surface with fine, sparse punctures, on sides with coarse punctures. Abdominal ventrites shiny, anterior margin distinctly fluted, without microreticulation, with belt of dense, coarse, mainly longitudinal punctures. Pygidium with posterior half matt, eroded, with distinct microreticulation, additionally with distinct longitudinal, shiny median carina.

Aedeagus ( Figs 13 View FIGURES 10–16 ). Parameres somewhat shorter than phallobase, elongate, in lateral view with small membranous area in the middle and with somewhat larger membranous process before the apex. Aedeagus similar in shape to other Odontolochini and as well a lot of members of Psammodiini and Eupariini .

Etymology. Toponymic; an adjective derived from the name Peru, where the new species was collected.

Diagnosis. Saprolochus peruvianus can be distinguished from all other known species by the combination of characters: body length less than 3 mm; central part of clypeus with small and large punctures, irregularly, moderately densely distributed; pronotum with lateral border reduced posteriorly, emarginate with one or two small teeth, lateral margin between teeth weakly sinuate in dorsal and lateral view; lateral pronotal border with tooth anterior to basal emargination in addition to basal tooth; lateral border of pronotum at most with indistinct row of punctures the same size as other large punctures; larger punctures of pronotum distinctly larger posteriorly than anteriorly; humeral callus of elytra shiny, with only a trace of microreticulation, with very sparse fine punctation; elytral striae not increasingly wider and deeper toward sides, elytral intervals shiny, without microreticulation; punctation of elytral intervals arranged in very indistinct rows.
