 Description. TL 4.0– 4.5 mm; EW 1.9–2.3 mm; see Table 1 for remaining body measurements.   
 Color. Dorsal surface yellow to testaceous. Elytra with broad basal diffuse band extended to lateral margins in some specimens (Fig. 3); venter yellowish.   
 Sculpture and punctation. Elytron with a submarginal and 10 discal striae (Fig. 3). First three abdominal ventrites with short curved strioles.   
 Structure. Prosternum rounded medially, with anterior margin sinuate; prosternal process short, oval, finely margined laterally, bluntly pointed apically, flattened apically and broadly contacting anteromedial metaventral process; rounded lobes of metacoxal processes covering base of trochanters. Male protibia with two ventrobasal emarginations; metatibial spurs acute apically; metatarsomeres 1 to 4 flattened ventrally; metatarsal claws equal.   
 Male genitalia. Median lobe with outside margin abruptly expanded in middle part (Figs. 21a, b); parameres broad, inner margin with short setae over apical half (Fig.21c).   
 Sexual dimorphism. Males with pro- and mesotarsomeres 1–3 widened, with sucker-like setae. Protibia with two ventrobasal emarginations. Female protibia without ventrobasal emargination.   
 Diagnosis. Adults of C. cordovai sp. nov. are recognized by the combination of the following characters: elytron with a posterolateral submarginal stria and 10 discal striae (Fig. 3); male protibia with two ventrobasal emarginations; median lobe with abrupt widening in middle part (Figs. 21a,b); parameres with short setae on inner margin (Fig. 21c).   
 Copelatus cordovai sp. nov. can be confused with the Nearctic species C. glyphicus (Say, 1823) due to the similar pattern of 10 discal striae, but can be separated from it by the thicker median lobe (the median lobe of C. glyphicus is slender and strongly curved to the side apically).   
 Etymology. The specific epithet cordovai is a noun in the genitive case which honors Yunier Córdova Cóbas (Barcelona, España) for his contribution and help to the senior author’s studies on aquatic coleopterans.   
 Ecology. Copelatus cordovai sp. nov. was collected in lentic (permanent and temporary) habitats with abundant aquatic vegetation, muddy bottom and high water temperatures, from lowlands up to 50 m a.s.l. (Fig. 34)   
 Distribution. In Cuba, Copelatus cordovai sp. nov. is recorded from both western (Isla de la Juventud) and eastern parts of the country (Las Tunas and Granma provinces) (Fig. 27).
