Edessa viridula sp. n.

( Figs 1 , 6 A–B , 8 A , 9 )

Etymology. Name refers to the green color of the body.

Holotype male. BRAZIL, São Paulo: Vila Bastos, Santo André , III–1962, L. Stowbunenko col. (23°39’35.47” S 46°32’13.23” W) ( MZUSP).

Paratypes. BRAZIL, Mato Grosso: ♀ Utiariti, Rio Papagaio , 1–12–XI–1966, Lenko & Pereira (13°44’03.13” S 58°33’30.77” W) ( UFRGS) ; ♂ 72215, 18–V–1940 (MZUSP); ♂ Chavantina, 6–1947, Carvalho J. C. M. (14°39’49.16” S 52°21’31.35” W) (MNRJ); Minas Gerais: ♂ Rio Claro , 1947, Carvalho e col. (22°24’06.30” S 45°16’32.21” W) ( MNRJ) ; São Paulo: ♀ Vila Bastos, Santo André, III–1 962, L. Stowbunenko col. (23°40’26.75” S 46°32’12.94” W) ( MZUSP) ; Paraná: ♂ Ponta Grossa, XII–1938, Camargo e col. (25°05’57.07” S 50°09’30.28” W) ( UFRGS) ; ♂ Teixeira Soares, distrito de Guaraúna, 17–I–1939, Camargo (25°19’25.12” S 50°21’1.88” W) (MNRJ);

Measurements. Head length (1.4–1.6); head width (2.3–2.5); pronotum length (2.5–2.6); pronotum width (6.5–7.2); scutellum length (5.2–5.6); scutellum width (4.1–4.6); length of antennal segments (I: 1.1–1.5; II: 1–1.5; III: 2.1–2.5; IV: 2.6–2.8; V: 2.3–2.9); total length (11.3–13); abdominal width (7.3–7.8).

Diagnose. Head not punctured. Pronotum not rugose. Arms of the anterior bifurcation of the metasternal process ( Fig. 1 E ) long and rounded apically, receiving fourth rostral segment almost entirely. Peritreme almost reaching half of the distance between ostiole of the scent gland and lateral margin of the body ( Fig. 8 A ). Evaporatorium with a long and raised crest in mesopleuron delimited by sulci; contiguous margin of meso and metapleuron also raised; metapleuron with two distinct raised crests one short medial and the other long distal. Spiracles concolorous with abdominal sternites; trichobothria placed in light yellow callous. Antennae and legs spotless.

Male ( Figs 1 A–C ). Superior process of the genital cup formed by a line of tiny brown tubercles. Basal part of the paramere wider than its distal portion, with two distinct globose lobes ( Fig. 1 C ); distal lobe curved posteriorly.

Female ( Fig. 1 D ). Gonocoxites 8 punctured with outline rounded; sutural border contiguous. Base of laterotergites 9 barely excavated.

Comments. Edessa viridula sp. n. is very similar to the other species of the group, except E. exigusternata sp. n., but they can be easily separated by length of the peritreme, shape of the paramere and gonocoxitos 8.

Distribution ( Fig. 9 ). Brazil: Mato Grosso, Minas Gerais, São Paulo and Paraná.
