Paraedessa cyanodorsata Silva & Fernandes sp. nov.

(Figures: 16–20, 52, 59)

Etymology. The specific name makes reference to the blue coloration of the dorsal face of the abdomen. Material examined. Holotype male. VENEZUELA. Zulia: Rio Escalante 30km de Santa Cruz, 26-IX-1951 (MPEG).

Measurements. Total length: 10.1–12.9; head length: 1.1–1.5; head width: 2.5–2.7; pronotal length: 2.3–2.7; pronotal width: 6.5–7.2; abdominal width: 6.2–6.8; length of antennal segments (I: 0.5–0.8; II: 11.0–1.2; III: 1.2– 1.6; IV: 2.7–3.0; V: 2.4–2.8).

Male: Pygophore with dorsal rim concave and transversally grooved ( Fig. 16 ); posterolateral angle not developed ( Figs. 16, 18 ). Genital cup processes triangular, straight, small, slightly concave medially, located lateral to proctiger, not surpassing dorsal rim ( Figs. 16–17 ). Parameres flat, furrowed, barely concave; anterior expansion large and subtriangular, distal half of parameres with both acuminate lobes (lo) almost equally long, upper lobe square and bigger than lower lobe ( Fig. 17, 19 ); apex laterally curved ( Figs. 17, 19 ) surpassing dorsal rim. Dorsal face of proctiger as long as wide, whole, without a distal shallow concavity ( Figs. 16–17 ). Lateral face of proctiger with a strong constriction forming a narrow bridge that connects the dorsal face to the expansion of proctiger ( Figs. 16–17 ). Lateral expansion of proctiger subrectangular, narrow, twice as wide as the anal opening, projected dorsally up to level of dorsal face ( Figs. 16–18 ). Ventral rim with lobes developed, not reaching level of posterolateral angle ( Fig. 18 ).

Female: Gonocoxites 8 rectangular (excluding the posterolateral angle), contiguous medially; posterolateral angle dentiform, surpassing the level of gonapophyses 8 ( Fig. 20 ); gonocoxites 8 overlapping gonapophyses 8 but they are detached in most of its extension leaving a big hole in between them.

Comments. Paraedessa cyanodorsata sp. nov. is reconized by the subrectangular form of the lateral expansion of proctiger; shape of the parameres; gonocoxites 8 rectangular (excluding the dentiform angle), medially contiguous and posterolateral angle surpassing the posterior margin of gonapophyses 8. This species can be confused with P. subretangulata sp. nov. because of the shape of the lateral expansion of proctiger and the small reduction of gonocoxites 8 when compared with the others species. However, for males, the shape of the parameres is enough to separate them. Also, P. cyanodorsata females’ show the gonapophyses 8 more exposed.

Distribution ( Fig. 59 ): COSTA RICA: Puntarenas; PANAMÁ: Portobelo; VENEZUELA: Yaracuy, Zulia.
