Diagnosis. Among the other members of the genus, this species can be easily identified by the large prominent eyes.

Description. Length: 5.9 mm. Colouration: Dark brown; margin of pronotum and elytra lighter brown; abdomen reddish; legs and antennae yellow.

Head 0.81 mm long, 1.28 mm wide; eyes thick; strongly prominent; more than twice as long as temples; sides of fore-head convergent; anterior edge of clypeus crenulate and slightly produced in smooth curve; transverse row of short yellow setae and pair of long yellow setae at anterior edge; groups of yellow setae on supraocular area including pair of long yellow setae; pair of long yellow setae on line between anterior edge of eyes; six yellow setae on transverse line between posterior edge of eyes; impunctate; netlike microsculpture deep and dense except on small area at base of antennae; surface slightly shiny.

Antennae nearly as long as head and half of pronotum combined; oval second antennomere twice as long as wide; conical third antennomere still slightly longer than second; following antennomeres slightly increasing in width and each approximately quadrate.

Pronotum 1.09 mm long, 1.26 mm wide; widest at anterior angles; anterior angles slightly produced to short teeth; sides evenly narrowed in smooth curve to posterior angles; slightly emarginate in front of posterior angles; posterior angles obtuse; lateral margin moderately fine; widened to posterior angles; in dorsal aspect visible throughout its total length; punctation weak and sparse; on average, interstices between punctures four to six times as wide as diameter of punctures; pair of punctures with long yellow setae close to anterior edge and at posterior third; anterior setiferous punctures closer to each other than posterior setiferous punctures; extremely weak netlike microsculpture; surface nearly polished and shiny.

Elytra 1.45 mm long, 1.35 mm wide; punctation weak and sparse; hardly visible in weak coriaceous ground-sculpture; surface moderately shiny.

Abdomen with dense setiferous punctation; punctures deeper and denser than on fore-body; netlike microsculpture weak, but more distinct than on pronotum; surface moderately shiny.

Protibia 0.57 mm long, 0.17 mm wide; with eight spines at outer edge; spines not inserted on teeth; comb at inner emargination totally visible in posterior aspect; posterior face with dense setation; anterior face with longitudinal row of setae.

Aedeagus weakly sclerotised; right side of apical lobe soft; apical lobe slightly curved; only one sensilla at inner edge of apical lobe.

Etymology. The specific name was selected to honour the collector, Martin Fikáček (NMPC).

Distribution. Known only from the type locality.
