Diagnosis.

A Euchroina genus of beetles that are medium-sized (8.2-10 mm), black coloured, brachypterous, with the following combination of characters: convex eyes; mentum with bifid tooth and large labial pits; pronotum sides posteriorly straight to slightly convex; elytra with 3-4 (rarely 2 or 5) discal setiferous puncture in stria 3/interval 3, with last puncture in posterior third of elytron; intercoxal process of prothorax subquadrate, distinctly bordered at sides and backwards; metaepisterna as wide as long; abdominal sternites V–VII with transverse basal sulci complete and well-impressed; mesotibia and metatibia straight in both sexes, mesotibia distally with slight inner callus in males; tarsomeres glabrous dorsally, with segment 5 setose ventrally; distal part of median lobe of aedeagus considerably curved to left in dorsal aspect; spermatheca with appended gland spherical and elongate diverticulum.

Description.

None required because the genus is monobasic, and its characters are the same as those of its type species.

Etymology.

A prefix in apposition (masculine), formed from the Greek παρά-, meaning “beside”, “near”, “alongside”, and the name of the Mediterranean pterostichine genus Orthomus to which the new taxon is related.
