Nascimento, Dariane Amorim Do, Mendonça, Maria Thayane Da Silva & Fernandes, Jose Antonio Marin, 2017, Description of a new group of species of Edessa (Hemiptera: Pentatomidae: Edessinae), Zootaxa 4254 (1), pp. 136-150 : 143

Edessa rugulata sp. n.

( Figs 4 , 7 A–B , 8 D , 9 )

Etymology. Reference to the short peritreme of the species. Rugula—small crease.

Holotype male. BOLIVIA, Cochabamba: Cristal Mayu, Chapare , 10–XII–1954, Luis E. Peña (17°00’22.62” S 65°38’28.62” W) ( USNM).

Measurements. Head length (1.4); head width (2.5); pronotum length (2.5); pronotum width (6.0); scutellum length (4.9); scutellum width (3.6); length of antennal segments (I: 0.7; II: 1.0; III: 1.0; IV: 1.5; V missing); total length (11.6); abdominal width (6.6).

Diagnose. Pronotum rugose. Arms of the anterior bifurcation of the metasternal process clavate ( Fig. 4 D ); excavation short receiving part of the fourth rostral segment. Peritreme reaching 1/3 of the distance between ostiole of the scent gland and lateral margin of the body ( Fig. 8 D ). 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 ventral surface. Trichobothria in yellowish calli. Antennae and legs spotless.

Male ( Figs 4 A–C ). Superior process of the genital cup reduced to a black line. Ventral part of the paramere with one barely distinct and rounded lateral lobe, base barely wider than distal part; lobes not distinctly projected posteriorly.

Comments. Female unknown. This species is very similar to the others has the shortest peritreme ruga in the group and is the only one with claviform arms of metasternal process.

Distribution ( Fig. 9 ). Bolivia: Cochabamba.
