Curicta venezolana De Carlo, 1960 View in CoL : Keffer, 1996: 177 (Synonymy).

Curicta intermedia Martin, 1898 View in CoL : Roback and Nieser, 1974: 40–41 (Misidentification).

Diagnosis – This species can be recognized by the following combination of characteristics:distinct carina at apex of head; pronotum densely covered with granules and presence of well-defined profemoral grooves ( Fig. 2D View Figure 2 ) ( Keffer, 1997).

Supplemental description – Specimens examined: 23 females and 23 males. Females: Body length, 20.0–25.0 ( Fig. 2A View Figure 2 ); profemur length, 5.6–7.3 ( Fig. 2C View Figure 2 ); siphon, 12.5–20.0. Male: Body length, 18.0– 22.0 mm; profemur length, 4.9–6.2; siphon, 7.0–15.0.Female genitalia: Gonapophysis-1 elongate, with dorsal angles more anteriorly than posteriorly curved, well-sclerotized.In lateral view, gonapophysis-1 broadly triangular, nearly reaching length of gonapophysis-2, also well-sclerotized. Gonapophysis-2 dorsoventrally flattened, linear, slightly curved medially, extending posteriorly beyond posterior margin of gonapophysis-1 ( Fig. 2F View Figure 2 ). Male genitalia. Parameres elongate and curved inward apically.

Note – The pronotum of Curicta is often covered with mud or other bottom substrate in its aquatic habitat, which may present challenges in identifying granules on the pronotum of C. granulosa ( Fig. 2B View Figure 2 ). This represents the first records of Curicta granulosa from the state of Maranhão.
