Copelatus bromeliarum (Scott, 1912)

( Figs 1C , 2C–D )

Aglymbus bromeliarum Scott, 1912a: 433 ( Trinidad: El Tucuche).

Copelatus bromeliarum : Balke et al. 2008: 6357.

Material examined: Trinidad: 3♂♂ 5♀♀, northern range, summit of Mount El Tucuche , 10°44ʹ22.8″S, 61°24ʹ29″W, 893 m, A.L. Viloria & A.D. Rincon leg. (NMPC, ZSMG) . Venezuela: 1♂, Aragua, Henry Pittier NP, La Cumbre , 1500 m, 5.viii.2001, Hornburg leg. (LHCM) ; 4♀♀, Aragua, Henri Pittier NP, 1100 m, ( Guzmania sp. , 40 m above floor on Gyr. curibensis), 4.v.2004, Escalona, Villareal & Arias leg. (ZSMG) ; 1♂ 2♀♀, Caracas , IVIC, 1700 m, 27.i.2004, Balke & Garcia leg. (ZSMG) ; 6♂♂ 11♀♀, Maracay, Rancho Grande , 1200 m, 22.i.2004, Balke, Garcia & Escalona leg. (NMPC, ZSMG) .

Diagnosis: Habitus drop-shaped, more strongly attenuated posteriorly than anteriorly, broadest at 1/3 of elytral length, slightly convex.Body black, appendages testaceous ( Fig. 1C ). Dorsal surface submatt due to well impressed reticulation and presence of finelongitudinalstriolae.Headmoderatelybroad, c. 0.60 × width of pronotum, trapezoidal. Antennae with antennomeres rather broad, thus of stouter appearance. Pronotum transverse, broadest at posterior angles; sides strongly and evenly curved, lateral beading distinct except for anterior corners. Elytral striation consisting of six superficially impressed discal striae: odd striae often incomplete and badly perceptible due to striolation. Protibia modified, slightly angled near base, distinctly broadened anteriorly, club shaped. Pro- and mesotarsomeres 1–3 distinctly broadened, ventrally with adhesive setae. Natatorial setae present only on dorsal side of metatarsomeres. Median lobe of aedeagus in lateral aspect ʻCʼ- shaped, apex obtusely pointed; in ventral aspect median lobe attenuated in apical fourth, apex turned left ( Fig. 2C–D ). Parameres broad, ʻDʼ- shaped. Female smaller than male: TL ♂♂: 5.9–6.5 mm; TL ♀♀: 5.1–6.1 mm.

Distribution: The species is so far known from Trinidad Island and from the Cordillera de la Costa in northern Venezuela ( Fig. 3 ).
