Belostoma fittkaui De Carlo, 1966: 100–101  .

Belostoma fittkaui: Schnack, 1976: 34  .

Supplemental description. Size and shape. Length: male (n=10) = 28.4–34.0, female (n=9) = 28.7–32.4; width: male = 13.8–17.5, female = 14.2–16.4. Body broad.

External morphology. Head: eyes triangular, with lateral margins straight; anteoculus as long as interoculus, about 0.94–1.00× ( Fig. 1CView FIGURE 1); vertex with a carina poorly elevated; article II of labium distinctly shorter than III, about 0.62–0.74×. Thorax: prosternal keel quite elevated with apex rounded, projecting forward; pronotum trapezoidal with lateral margins straight and a narrow fold extending to posterior portion; fore femur slender, subequal in width with middle femur; scutellum distinctly carinate. Abdomen: pilosity entirely covering sterna and connexivum, including second through seventh segments.

Male genitalia. Dorsal arms of phallosoma convergent, covering lateral margins of diverticulum and extending to distal portion of diverticulum in dorsal view; phallosoma slightly curved and diverticulum with a poorly developed ventral protuberance in lateral view; diverticulum more elliptical in ventral view.

Diagnosis. Article II of the labium distinctly shorter than III, about 0.62–0.74×, pilosity entirely covering the sterna and connexivum, and the body broad 2.0× as long as broad are diagnostic for this species.
