Type material.— ARGENTINA. HOLOTYPE: male ( INHS), “ Salta / Aguaray / 11 Jan. 1988 / Heath-Sanborn- Noriega Coll.” . PARATYPES: eight male same data as holotype (seven male MSHC, one male AFSC); one male ( MSHC) “ Tucuman / 3 km So. of Tapia / 18 Dec. 1986 / Al Sanborn Coll.”; one male ( MSHC) “ Tucuman / 3 km So. of Tapia / 18 Dec. 1986 / M.S. Heath Coll. ”; one male ( MSHC) “ Tucuman / 3 km So. of Tapia / 18 Dec. 1986 / J.E. & M.S. Heath Coll. ”; one female ( MSHC) “ Tucuman / 3 km So. of Tapia / 18 Dec. 1986 / F. Noriega Coll. ”.

Etymology. The species is named for the green stripe on the posterior of the abdominal segments.

Diagnosis. — Parnisa lineaviridia sp. n. can be separated from P. demittens (Walker, 1858) and P. proponens (Walker, 1858) by its smaller size (these species have body lengths greater than 15 mm). The body markings and general body coloration differentiate the species from the green P. viridis sp. n. and the castaneous P. moneta ( Germar, 1830) . Parnisa designata (Walker, 1858) is castaneous with a red venter. Parnisa haemorrhagica Jacobi, 1904 is green with an orangish-reddish abdominal venter. Parnisa angularis Uhler, 1903 has a ridged abdomen and brown-banded tergites, and P. protracta Uhler, 1903 has a red abdomen. The new species lacks the longitudinal abdominal markings found in P. fraudulenta ( Stål, 1862) .

Description

Coloration.—Ground color testaceous marked with piceous.

Head.—Testaceous with transverse piceous stripe enclosing ocelli, supra-antennal plate anterior margin with greenish tinge, about as wide (1.0–1.1X) as mesonotum. Ocelli red, eyes testaceous with tawny margin. Head covered with white pile, more dense in sutures, longer posterior to eye. Postclypeus rounded anteriorly, centrally sulcate dorsally and posteriorly with ten transverse grooves, white pile laterally and within transverse grooves. Postclypeus testaceous with longitudinal piceous marks on either side of tawny longitudinal mark on anteroventral midline, piceous mark begins at supra-antennal plate, fuses posterior to tawny mark and terminates before junction with anteclypeus. Anteclypeus piceous with white pile laterally. Rostrum testaceous with piceous tip reaching to hind coxae. Gena testaceous with piceous transverse stripe between eye and postclypeus and short white pile. Lorum testaceous with long white pile. Antennal segments fuscous except tawny distal scape and proximal pedicel.

Thorax.—Pronotum testaceous, piceous on disc between midline and paramedian fissure, anteriorly between paramedian and lateral fissures, and central portion of disc between lateral and ambient fissures, additional curved piceous mark along midline and pronotal collar between medial terminus of paramedian and lateral fissures. Central disc between lateral and paramedian fissures marked with piceous and submedian sigillae mark reduced in some paratypes. Lateral part of pronotal collar absent. Pronotum covered with short white pile. Mesonotum testaceous, submedian and lateral sigillae fuscous. White pile on disc, longer and more dense laterally and between anterior arms of cruciform elevation. Cruciform elevation lighter in color than rest of mesonotal disc. Metanotum testaceous, Ventral thoracic plates testaceous except piceous basisternum 2, covered with short white pile.

Forewing and hind wings.—Hyaline. Forewing with eight apical cells, hind wings with five apical cells. Venation tawny except testaceous radius & subcostal vein in basal cell and anal vein 2 + 3, becoming darker near apex. Basal cell hyaline. Basal membrane grayish brown. Hind wing venation tawny. Vanal fold, anal cell 3, anal cell 2 and anal cell 1 along anal veins 2 and 3 grayish, infuscation in distal anal cell 3 and anal cell 2 near grayish area.

Legs.—Fore coxae testaceous with greenish tawny stripes, middle and hind coxae tawny with fuscous lateral spot on base. Trochanter tawny marked with testaceous medially. Fore femur testaceous striped with greenish tawny, primary spine largest and oblique, secondary spine smaller and more upright, tertiary spine slightly smaller and more oblique, and very small, oblique apical spine, spines fuscous with piceous tips. Middle and hind femora with proximal half and distal apex tawny, fuscous between tawny regions. Fore tibia fuscous, middle and hind tibia tawny proximally and fuscous distally, left hind tibia tawny in holotype. Tibial spurs and comb tawny with testaceous tips. Tarsi testaceous, darker distally. Pretarsal claw testaceous with fuscous tips.

Operculum.—Male operculum testaceous 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 medial meracathus. Meracanthus tawny with testaceous base, extending two thirds length of operculum. Operculum with short white pile. Female operculum tawny with lateral fuscous spot on base, operculum with angled lateral margin, rounded posterolateral angle, straight posterior margin, pointed medioposterior angle and curved anteromedial margin, extending to middle of sternite II. Meracanthus tawny with fuscous spot on base, extending beyond posterior operculum.

Abdomen.—Testaceous. Posterior margin of tergites 3–8 green. Anterior margin of tergite 2 between timbal cavities piceous. Transverse fuscous mark across midline of anterior tergites 3 and 4. Anterior lateral portion of tergite 3 tawny, lateral tergite 7 greenish. Sternites dark tawny, sternites III–VI and epipleurites 2–7 with green posterior margin, male sternite VII dark tawny anteriorly, greenish posterolaterally and light testaceous posteromedially, male sternite VIII dark tawny. Tergites and sternites covered with short white pile, longer on male sternite VIII. Timbal with eight ribs.

Male genitalia.—Pygofer testaceous with fuscous lateral stripes. Upper pygofer lobe arching to fuscous pointed tip beyond level of dorsal beak. Uncus lobes absent, anal styles testaceous with ochraceous base. Claspers tawny, parallel sided at base, slightly angled medially at base, terminating with a lateral curve and reducing to a point. Aedeagus castaneous, tubular with recurved endotheca supporting tawny membrane.

Female genitalia.—Testaceous with anterior dorsomedial, dorsolateral and lateral fuscous stripes not reaching posterior margin of abdominal segment 9, anterior dorsomedial and dorsolateral stripes separated by tawny stripe anteriorly, additional tawny stripe ventrolaterad. Sternite VII with deep medial notch, short arched posterior margin next to notch before arching lateral margin extends length of sternite. Abdominal segment 9 with long and short white pile, dorsal beak bent dorsally. Anal styles testaceous, about as long as dorsal beak. Gonocoxite IX tawny. Gonapophysis VII castaneous, gonapophysis X piceous with long pile, extending well beyond dorsal beak.

Measurements (mm).— N = 12 males or 1 female, mean (range). Length of body: male 11.8 (11.1–12.5), female 14.4; length of forewing: male 12.8 (11.6–13.6), female 14.0; width of forewing: male 4.8 (4.5–5.3), female 4.9; length of head: male 1.66 (1.5–1.8), female 1.8; width of head including eyes: male 3.73 (3.6–3.8), female 3.7; width of pronotum including suprahumeral plates: male 4.01 (3.6–4.3), female 4.3; width of mesonotum: male 3.54 (3.4–3.8), female 3.6.

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