Etymology. The species is named for its green coloration.

Diagnosis. —The new species is unique among its cogeners in its green coloration and the lack of any head, thoracic or abdominal markings. The most similar species is P. haemorrhagica Jacobi, 1904 which is green but has an orangish-reddish abdominal venter.

Description

Coloration.—Ground color green, fades to tawny in specimens placed in softening jar.

Head.—Green, about 0.97X as wide as mesonotum. Ocelli rosaceous, eyes testaceous with tawny margin. Long white pile posterior to eye and on ventral head. Postclypeus rounded anteriorly, centrally sulcate with eight transverse grooves and white pile laterally. Anteclypeus green with white pile laterally. Rostrum tawny with fuscous lateral tip reaching to middle trochanter. Gena and lorum green. Scape green, remaining antennal segments fuscous except tawny proximal pedicel, distal pedicel, and proximal first flagellum.

Thorax.—Pronotum green, lateral part of pronotal collar absent. Mesonotum green, light tawny within submedian sigillae in some paratypes. White pile laterally and between anterior arms of cruciform elevation. Metanotum green. Ventral thoracic plates green with sparse, short, white pile.

Forewing and hind wings.—Hyaline. Forewing with eight apical cells, hind wings with five apical cells. Venation green. Basal cell hyaline. Basal membrane white marked with orange and green. Hind wing venation green. Vanal fold, anal cell 3, anal cell 2 along anal vein 3 greenish.

Legs.—Green, tarsi and distal tips of tibiae tawny, all green except tawny distal pretarsus in some paratypes. Fore femur with primary spine largest and slightly oblique, secondary spine smaller and more oblique, tertiary spine slightly smaller than and parallel to secondary spine, and very small, oblique apical spine, spines green with fuscous tips. Tibial spurs and comb green with tawny tips. Pretarsal claw tawny with fuscous tips.

Operculum.—Male operculum and meracanthus green not covering tympanal cavity or reaching anterior margin of sternite II. Lateral margin straight, posterior margin curving to rounded medial margin, anteromedial margin curving around meracanthus to base. Medial margin extends to level of middle width of posterior coxa. Meracanthus extends two thirds length of operculum. Operculum with white pile near base and radiating from margin. Female operculum and meracantus green, operculum with angled lateral margin, rounded posterolateral and median angles, straight posterior margin and curved anteromedial margin, extending to middle of sternite II. Meracanthus extending beyond posterior operculum.

Abdomen.—Green with white pile, more dense dorsolaterally. Timbal with eight ribs.

Male genitalia.—Pygofer green, upper pygofer lobe arching to pointed tip at level of dorsal beak. Uncus lobes absent, anal styles green with ochraceous base. Claspers green, parallel sided at base, swelling at terminus bend posteriorly when meeting medially. Aedeagus tawny striped with green, expanding laterally near apex, terminating in a small castaneous curved spine.

Female genitalia.—Green. Sternite VII with deep medial notch. Abdominal segment 9 with sparse white pile, dorsal beak bent dorsally. Anal styles green, about as long as dorsal beak. Gonocoxite IX green. Gonapophysis VII tawny with green base. Gonapophysis X greenish tawny with long pile, extending to level of dorsal abdominal segment 9.

Measurements (mm).— N = 18 males or 1 female, mean (range). Length of body: male 12.2 (10.5–13.1), female 13.9; length of forewing: male 12.9 (12.0–13.7), female 15.0; width of forewing: male 4.9 (4.4–5.3), female 5.1; length of head: male 1.5 (1.3–1.8), female 1.5; width of head including eyes: male 3.3 (3.1–3.5), female 3.6; width of pronotum including suprahumeral plates: male 3.9 (3.7–4.1), female 4.2; width of mesonotum: male 3.5 (3.2–3.7), female 3.8.

Notes. — Parnisa viridis sp. n. is from the Chaco floristic province ( Sanborn et al. 2011a).
