Measurements. Total length: 10.7–12.4; head length: 1.1–1.4; head width: 2.4–2.5; pronotal length: 2.4–2.7; pronotal width: 6.1–7.4; abdominal width: 6.1–7.0; length of antennal segments (I: 0.5–0.9; II: 0.8–1.1; III: 1.1– 1.6; IV: 1.7–2.6; V: 1.9–2.6).

Male: Pygophore with dorsal rim concave and furrowed ( Fig. 40 ); posterolateral angles developed ( Figs. 40, 42 ). Genital cup processes triangular, small, concave, located lateral to proctiger and not surpassing dorsal rim ( Fig. 41 ). Parameres flat, triangular, long and barely concave ( Figs 40–41 ); anterior expansion small and subtriangular, distal half with two acuminate lobes (lo), upper lobe clearly bigger than the lower that is tiny to inconspicuous ( Figs. 41, 43 ); acute apex laterally curved not surpassing dorsal rim ( Fig. 42 ). Dorsal face of proctiger as long as wide, entire, without a distal shallow concavity ( Figs. 40–41 ). Lateral face of proctiger with a strong constriction forming a narrow bridge that connects the dorsal face to the proctiger expansion ( Figs. 40–41 ). Lateral expansion of proctiger subrectangular, narrow, twice as wide as the anal opening; margin rounded ( Figs. 40–42 ); projected dorsally to the level of the dorsal face ( Figs. 40–41 ). Ventral rim with lobes slightly developed, not reaching the level of the posterolateral angle ( Fig. 42 ).

Female: Gonocoxites 8 rectangular (excluding the posterolateral angle), medially contiguous, posterolateral angle dentiform, reaching or barely surpassing the posterior margin of gonapophyses 8 ( Fig. 44 ). gonocoxites 8 overlapping gonapophyses 8 but they are slightly detached at the lateral corners leaving a small hole in between them.

Comments. Paraedessa subretangulata sp. nov. is identified by a small genital cup process; distal half of the parameres; lateral expansion of the proctiger subrectangular; gonocoxites 8 with posterolateral angle dentiform and reaching or barely surpassing the posterior margin of gonapophyses 8. This species shares with P. cyanodorsata sp. nov. shape of the lateral expansion of proctiger; strong constriction on lateral face of proctiger and gonocoxites 8 rectangular.
