( Figs. 6 , 12 , 23, 24 , 30–32, 52, 53 , 57 , 62 )

Hydraena guadelupensis Orchymont, 1923: 37 .— Perkins, 1980: 145.— Jäch et al. 2000: 80.— Brojer & Jäch, 2011: 77.

Diagnosis: Habitus as in Fig. 30. Male terminalia: Ventrite VII as in Fig. 12 , subrounded, anterior margin angulate; spiculum gastrale long and straight, firmly attached to ventrite; terminal tergite reniform ( Fig. 6 ). Female terminalia: Gonocoxite ( Fig. 23 ) with outer plate symmetrical, anterolateral condyles small and a pair of subapical tufts of setae; inner plate symmetrical with a elongate impression; last tergite ( Fig. 24 ) elliptic, with a distal row of stout, small setae. Male genitalia as in Figs. 31–32 . Spermatheca: Long and slender, markedly angulate in lateral view ( Figs. 52–53 ); spermathecal duct sinuate, enlarged in proximal half. For a detailed external description see Perkins (1980: 145).

Material examined: Santiago de Cuba: 3 males, 7 females (in alcohol) ( BSC-E) 4 males, 1 female (drymounted) ( CUMS): “ CUBA: Santiago de Cuba, Río San / José, Chan-Chan , Loma del Gato / 20º01’49,4’N 76º02’11,5’’W, 353 m / 25-VI-2009, coll.: A. Deler- / Hernández & F. Cala-Riquelme ” .

Distribution: Costa Rica, Jamaica, Virgin Islands and Guadalupe ( Perkins 1980). The presence of H. guadelupensis in eastern Cuba ( Fig. 57 ) gives continuity to its distribution through the Caribbean.

Habitat: In eastern Cuba it has been collected exclusively in the margins of a well preserved mountain stream shaded by a dense forest canopy, as in Fig. 62 .
