Copelatus insolitus: GUNDLACH (1891: 37) View in CoL , YOUNG (1942: 83), SPANGLER (1981: 153), NILSSON (2001: 66), PECK (2005: 44).

Type locality. Cuba, La Habana Province. The type locality of C. insolitus is Havana, but doubt exists on the occurrence of this species there due to the fact that all material examined previously from Cuba, Jamaica and Central America has been from rather high mountains ( YOUNG 1942).

Material examined. CUBA: SANCTI SPÍRITUS: Tope de Collantes , 29.vi.10, Y. S. Megna leg., 19 exs. ; Codina , 01.vii.2010, Y. S. Megna leg., 13 exs. SANTIAGO DE CUBA: La Majagua, 14.viii.2004, Y. S. Megna leg., 74 exs. ; La Platica , 12.vi.2004, Y. S. Megna leg., 3 exs. ; La Estrella , 01.xii.2005, Y. S. Megna leg., 22 exs. ; La Cubana , 02.xii.2005, Y. S.

Diagnosis. TL 5.3–5.9 mm; EW 2.5–2.9 mm; see Table 1 for remaining body measurements. Female unlike male, with elytral striae undulating/anastomosing; male protibia with two ventrobasal emarginations, and median lobe in lateral aspect as in Figure 14a View Figs . See under C. darlingtoni .

Ecology. All material examined previously from Cuba, Jamaica and Central America has been from rather high mountains ( YOUNG 1942). The species was frequently collected in backwaters of small streams with muddy-stony bottoms, abundant detritus, located in highlands with a low exposure to sun and without aquatic vegetation.

Distribution. This species is known from Cuba, Jamaica, Hispaniola and Central America ( YOUNG 1942). It is widely distributed in Cuba ( Fig. 31 View Figs ).

Remarks. The type locality of C. insolitus is Havana, but doubt exists on the occurrence of this species there due to the fact that all material examined previously from Cuba, Jamaica and Central America has been from rather high mountains ( YOUNG 1942). The widespread C. insolitus is joined in Cuba by three other rather similar species apparently endemic to Cuba: C. barbouri , C. darlingtoni and C. montivagus . These Cuban species are not known to occur together. YOUNG (1942: 90) hypothesized that these species represented “developing endemic forms on the various isolated mountain ranges.” The males all lack well defined striae and possess similar, but different, color patterns; they can be separated by the shape of their protibiae and their genitalia. Females of C. darlingtoni , C. insolitus and C. montivagus are very similar and are best separated with comparative material or by association with males; the female of C. barbouri lacks elytral striae.
