Copelatus darlingtoni Young, 1942: 87 View in CoL . Copelatus darlingtoni: SPANGLER (1981: 167) View in CoL , FERNÁNDEZ (2001: 30), NILSSON (2001: 65), PECK (2005: 44).

Type locality. Cuba, Pinar del Río Province, Sierra del Rangel.

Material examined. HOLOTYPE: J ( MCZ):‘ Rangel Mts. , P. de R. Aug.24, 1936, about 1500 ft. [printed] / Cuba 1936, Darlington Collector [printed] / M.C.Z. Type 25902 [printed] / Holotype Copelatus darlingtoni [handwritten, ink]’. PARATYPE: 1 J ( MCZ): same data as holotype but no red M.C.Z. label [printed] / ‘ Paratype Copelatus darlingtoni Young [handwritten, ink]’.

Diagnosis. TL 5.5–5.6 mm; EW 2.5–2.8 mm; see Table 1 for remaining body measurements. Male without impressed striae on elytra but with weakly impressed series of punctures ( Fig. 5 View Figs ); protibia without ventrobasal emargination ( Fig. 17 View Figs ). Females unlike males, with numerous fine, undulating/anastomosing striae on elytra, leaving only front of head, clypeus, and apex of elytra smooth.

Copelatus darlingtoni externally differs from C. barbouri , C. insolitus and C. montivagus by the characters given in the identification key and also by the moderately larger (1.20–1.25 mm) aedeagus ( Fig. 12 View Figs ).

Ecology. All we know about this species is that it was collected in backwaters of small streams, located in highlands ( YOUNG 1942).

Distribution. Copelatus darlingtoni has been only recorded western parts of Cuba ( YOUNG, 1942) ( Fig. 30 View Figs ).

Remarks. The junior author has dissected the genitalia from the holotype male; they are now in a microvial on the specimen’s pin. No females of this species were examined for this study. Females of C. darlingtoni , C. insolitus and C. montivagus are very similar ( YOUNG 1942) and are best separated with comparative material or by association with males.
