Holotype male. Linnaeus indicated India as the species’ type locality, but Suriname is probably the correct one for P. stolida (Zoological Museum, University of Uppsala, Sweden).

Measurements. Total length: 10.6–11.7; head length: 1.1–1.6; head width: 2.5–3.5; pronotal length: 2.1–2.7; pronotal width: 6.2–6.6; abdominal width: 5.2–6.4; length of antennal segments (I: 0.5–0.6; II: 0.9–1.4; III: 1.2– 1.8; IV: 2.2–2.5; V: 2.2–2.6).

Male: Pygophore with dorsal rim rugulose, concave and furrowed; posterolateral angles poorly developed ( Figs. 1, 3 ). Genital cup processes subtriangular, curved, located lateral to proctiger; apex surpassing dorsal rim in lateral view ( Fig. 2 ). Parameres flat, slightly curved; anterior expansion large and subtriangular, distal margin straight; two distal expansions triangular, one directed anteriorly and the other posteriorly ( Fig. 4 ); apex not surpassing dorsal rim ( Figs. 1–2, 4 ). Dorsal face of proctiger as long as wide, entire, without a distal shallow concavity ( Fig. 1 ). Lateral face of proctiger slightly constricted ( Fig. 1 ). Lateral expansion of proctiger trapezoidal, narrow, curved and twice as wide as anal opening, projected dorsally beyond the dorsal face ( Figs. 1–2 ). Ventral rim with lobes developed, not reaching posterolateral angle level ( Fig. 3 ).

Female: Gonocoxites 8 narrow, separated medially, distal margin curved or sinuous; posterolateral angle projected and dentiform not reaching distal margin of gonapophyses 8 ( Fig. 5 ); usually gonocoxites 8 overlapping gonapophyses 8 but at the corner they are detached leaving a hole in between them.

Comments. The P. stolida type (Museum Zoological, University of Uppsala, Sweden) was examined by Pieter van Doesburg. Material compared with the type was examined, and the female is described here. Paraedessa stolida is recognized by the shape of the gonocoxites 8 and the parameres with two distal expansions instead of one like in other species; lateral expansion of proctiger trapezoidal, narrow and curved. Paraedessa stolida shares with P. albomaculata sp. nov., P. cyanodorsata sp. nov., P. paravinula , P. silvicola sp. nov. and P. subrentangulata sp. nov. the dorsal surface of proctiger whole, without a distal concavity. Lateral expansion of proctiger also present in P. albomaculata sp. nov., P. cyanodorsata sp. nov. and P. subretangulata sp. nov.. Gonocoxites 8 are medially separated like in P. albomaculata sp. nov., P. ecuadoriensis sp. nov., P. heymonsi , P. paravinula and P. verhoeffi .

Distribution ( Fig. 59 ): SURINAME: Saramacca, Paramaribo, Brokopondo; BRAZIL: Pará, Goiás.
