Anichtchenko, Alexander & Valainis, Uldis, 2023, Revision of the subgenus Omophron (s. str.) Latreille, 1802 (Coleoptera: Carabidae Omophron) of the Afrotropical region, Zootaxa 5284 (2), pp. 201-246 : 226

Omophron (Omophron) capense kmecoi ssp. n.

Type material. Holotype ♁: Namibia, Kavango, Rundu, Okavango riv., 16– 19.1.1999, 1050m, Rudolf Kmeco leg. [-17.906009, 19.740619] ( DUBC) . Paratypes: 2 ♀, idem ( RKC, MNHN); Namibia, 28.II.–6.III.1994, 18°14’S / 21°43’E, Kavango: Mahango, Game Reserve , leg. U. Göllner [-18.231883, 21.720392] (1 ♀, ZMHB) .

Differential diagnosis. Members of this subspecies have distinctly elongate elytra, with narrow lateral borders. The sides of the pronotum are almost straight, similar to those in O. capense pumilum ssp. n., while in O. capense s.str. they are slightly rounded. The first tarsomere in males is very strongly expanded, in comparison with those other subspecies ( Fig. 97 ). Aedeagus with wide apex, very slightly curved ventrally, with the sides of the aedeagus evenly narrow towards the apex, without the shape of a “bottleneck”.

Description. Body length 4.5–4.7 mm; width 2.9–3.1 mm. Habitus ( Fig. 33 ). Venter ( Fig. 37 ).

General taxon characteristics correspond to those given in the description of the nominate subspecies. Distinguishing features are indicated in the differential diagnosis and key.

Aedeagus with weakly downturned apex. Apical lamella long, sides of aedeagus taper gradually towards the apex, without shape of a “bottle neck” ( Fig. 42 ). Endophallus is slightly atypical for the species: both groups of spines consist of larger spines, and are located beside each other ( Fig. 47 ).

Etymology. New subspecies named after our friend and colleague Rudolf Kmeco ( Czechia).

Distribution. The new subspecies is known from two nearby localities in northern Namibia (Map. 3).
