Diagnosis. Frons with superficial longitudinal sulcus (Fig. 4 A); pronotum with weak lateral punctures, usually present on the entire lateral margin, sometimes completely absent (Figs 1 A, 3A); dorsal elytral striae weak (Fig. 1 A); apical elytral stria present, complete (Figs 5 A, 6B); 1st visible abdominal sternite with a pair of large glandular orifices posterad the posterior coxae (Fig. 6 A); propygidium with sparse punctures, coarser on anterior and lateral margins (Fig. 5 A); pygidium with a smooth area on the posterior margin (Fig. 5 A).
Description. Size range: length (pronotum + elytra): 6.2–6.8 mm, width (humeral region): 5–5.7 mm. Body form: body oval, convex. Head: frons about 1.5x wider than long, covered with weak punctures, with superficial longitudinal sulcus from the middle of the frons to the epistoma; frontal stria complete, slightly curved inward. Pronotum: without foveae, anterior angles projected; lateral pronotal stria complete; lateral punctures of pronotum extremely weak, usually present on the entire lateral margin, sometimes completely absent. Elytra: outer subhumeral stria continuous, present at the posterior third; inner subhumeral stria absent; first dorsal elytral stria weakly indicated, shortened on anterior third; second dorsal elytral stria weakly indicated, shortened on anterior and posterior sixth; third dorsal elytral stria weakly indicated on anterior half; fourth and fifth dorsal elytral striae absent; sutural elytral stria absent; apical elytral stria complete. Prosternum: prosternal lobe rounded, marginal prosternal stria shortened medially; lateral punctures of prosternal keel absent; prosternal keel with weak punctures medially, carinal striae of prosternal keel absent; prosternal process rounded. Mesoventrite: marginal mesoventral stria interrupted, starting slightly before the angles medially; lateral punctures absent; mesometaventral stria slightly curved towards prosternum medially, mesometaventral suture visible along its length. Abdomen: first visible abdominal sternite with a pair of large glandular orifices posterad the posterior coxae; propygidium with sparse punctures, slightly stronger and more coarse on anterior and lateral margins; pygidial punctures strong on anterior angles, weaker towards posterior margin and medially, absent on posterior fourth, with a superficial fovea on anterior angles. Male genitalia (Figs 7 A–E): eighth tergite subrectangular, with a pair of anterolateral projections, one on each side, posterior angles slightly angulated, posterior margin concave; eighth sternite with a superficial basal emargination; ninth tergite without apical emargination; tenth tergite with interrupted sclerotization, with one sclerotized area on each side, sides rounded; aedeagus elongated, base of parameres with a pair of projections in dorsal view, slightly emarginated in ventral view, apex truncated, parallel sided.
Distribution. Dominican Republic.
Etymology. This species is named after a great Histeridae researcher, Dr. Peter Kovarik, who loaned this interesting material to the corresponding author.
Remarks. When compared to Omalodes angelo sp. nov., this species has weaker punctures on the lateral margin of pronotum, a broader prosternum (mainly prosternal keel and process), punctures more sparse on the propygidium and a large glandular opening on each side, posterad to metacoxae. This species along with O. angelo sp. nov., O. haitianus and O. ruficlavis share a unique character (complete apical stria) and a sympatric distribution, limited to a portion of the Caribbean region (Haiti, Dominican Republic, and Cuba). Punctures on the pygidium are variable in O. kovariki sp. nov., most specimens possess stronger punctures on the anterior angles, weaker medially and absent posteriorly, but in a few specimens the medial punctures are slightly stronger.
