Type material.— ARGENTINA. HOLOTYPE: male ( INHS), “ La Rioja / Dto. Capital, 6.5 km / N.E. of Bazan / 19 Jan. 1988 / Heath / Sanborn-Noriega Coll.” . PARATYPES: four male and one female same data as holotype (three male and one female MSHC, one male AFSC).

Etymology. The species is named for the long male opercula which are the longest known for the genus.

Diagnosis.— Male specimens of C. longiopercula sp. n. can be differentiated by the length of their opercula as no other species of Chonosia has opercula reaching past half-length sternite III. Females can be differentiated by their larger body size (32.5 mm) from C. atrodorsalis Torres, 1945 (about 24 mm) and C. trigonocelis Torres, 1945 (about 26 mm). The notch on the posterior of sternite VII in the new species has parallel sides while the notch of C. septentrionala sp. n. is circular, the notch of C. papa ( Berg, 1882) rev. stat. has parallel sides posteriorly with a circular anterior terminus, and the notch expands anteriorly into a tear drop shape in C. crassipennis (Walker, 1858) .

Description

Coloration.—Ground color of tawny and ferruginous.

Head.—Head 1.23–1.4X wider than mesonotum with transverse fuscous mark between eyes enclosing ocelli, expanding anteriorly to central frontoclypeal suture and posteriorly to posterior margin of head, mark extends along anterior margin of eye to transverse mark across gena to antenna fusing with fuscous mark on supra-antennal plate. Tawny spots within transverse mark anterolateral to lateral ocellus, in posterior cranial depression and on posterior epicranial suture. Posterior to eye fuscous. Ocelli rosaceous, eyes greenish tawny. Long white pile on posterior head and posterior to eye. Postclypeus fuscous, rounded anteriorly, with ventral central sulcus, 12 transverse grooves, ferruginous transverse ridges, a central strip on midline, lateral margin of postclypeus and posterior junction with anteclypeus tawny, and with white pile laterally, within lateral transverse grooves, and within central sulcus. Anteclypeus ferruginous, tawny spot on anterior midline in paratypes. Rostrum ferruginous, labium piceous laterally and on tip, reaching to posterior coxae. Gena tawny with central fuscous stripe between postclypeus and eye. Lorum ferruginous. Long white pile on lateral gena and lorum, short white pile on medial gena and lorum. White pruinosity on lateral postclypeus, anteclypeus, gena and lorum. Scape ferruginous, pedicel dark tawny with fuscous distal annulus, remaining antennal segments fuscous.

Thorax.—Pronotum ferruginous, tawny along anterior margin and in midline. Fuscous marks on disc medial to paramedian fissures and connected across midline, and on anterior and central disc between paramedian and lateral fissures, and between lateral and ambient fissures. Lateral mark extends onto medial lateral margin of pronotal collar along anterior of the tawny pronotal collar and the ambient fissure fusing with a mark across the posterior disc between the posterior paramedian fissure and posterior lateral fissure, and fusing across midline in ambient groove. White pile in anterior lateral and paramedian fissures, pile in lateral ambient fissure in some paratypes. Mesonotum ferruginous with piceous submedian and lateral sigillae. Piceous marks anteriorly between sigillae, lateral to the lateral sigillae, and between anterior arms of cruciform elevation. The mark anterior to the cruciform elevation extends anteriorly along midline narrowing to anterior margin between submedian sigillae. Lateral mesonotum marked with tawny in some paratypes. White pile and pruinosity laterally, between anterior arms of cruciform elevation and along anterior margin, wing groove with heavy white pruinosity. Metanotum ferruginous with white pruinosity. Ventral thoracic plates fuscous except ferruginous posterior basisternum 2, posterior and medial episternum 2, lateral anepimeron 2, and posterior basisternum 3, epimeral lobe tawny. Venter covered with short white pile and white pruinosity.

Forewing and hind wings.—Hyaline. Venation tawny, fuscous between costa and radius + subcostal vein, pterostigma reddish. Basal cell, cubital cell and proximal third of clavus clouded with tawny. Basal membrane reddish. Hind wing venation tawny. Vanal fold, anal cell 3, anal cell 2 along anal veins 2 and 3, anal cell 1 along anal vein 2 and proximal half of anal vein 1, and proximal one fourth of radial cell reddish, reddish in anal cells 2 and 3 distally margined with infuscation. Infuscation in proximal cubital cells 1 and 2 and medial cell.

Legs.—Coxae, trochanter and femora ferruginous striped with fuscous. Fore femur with primary spine almost parallel to femur and larger, upright secondary spine, spines with fuscous base and tip along tawny ridge. Tibiae and tarsi ferruginous, striped with fuscous in one paratype, tibial spurs and comb testaceous with fuscous tips. Pretarsal claw ferruginous with fuscous tips. Legs with white pile and white pruinosity, both more dense proximally.

Operculum.—Male operculum ochraceous, with fuscous base, reaching posterior margin of sternite V, extend as far as the middle of sternite VII in some paratypes. Lateral margin stepped mediad, posterior margin rounded, medial margin straight until constricting at base. Medial margin extends to middle of hind coxa. Meracanthus ochraceous with fuscous base, base tawny in some paratypes. Operculum covered with short white pile, more dense at base, white pruinosity at base, more dense laterally. Female operculum ochraceous with fuscous base posterior margin rounded extending medially to middle of meracanthus, not reaching to posterior margin of sternite II. Meracanthus ochraceous with broad, fuscous base.

Abdomen.—Tergites ferruginous posteriorly and laterally, fuscous anteromedially with fuscous lateral spots. Timbal with 14 long and 13 short ribs. Tergites covered with short white pile, longer pile laterally and posteriorly, and white pruinosity, pruinosity more dense on lateral tergites 1 and 2, coverage decreasing on more posterior tergites. Sternites ferruginous, posterior margins of sternites III–VI red, red absent or anterior sternites fuscous in some paratypes, posterior sternite II fuscous. Long white pile medially on sternite II, white pruinosity dense on sternites I and II and laterally on sternites III–VII and epipleurites 3–6. Male sternite VII ferruginous with curving sides and straight posterior margin. Sternite VIII ferruginous with long white pile.

Male genitalia.—Pygofer ferruginous with fuscous anterior, pygofer upper lobe folded medially covered with white pruinosity. Pygofer basal lobe short with fuscous rounded terminus. Median uncus lobe with parallel sided base, tapering to rounded terminus at about half length, central ridge tawny. Anal styles ferruginous with fuscous tips, extending to level of dorsal beak. Aedeagus fuscous with tawny membrane and two curved fuscous spines, endotheca recurved and tawny.

Female genitalia.—Sternite VII dark tawny with lateral ferruginous spots and anterolateral fuscous marks, posterior margin sinuate with thin, parallel sided medial notch. Abdominal segment 9 ferruginous, fuscous anterodorsally and laterally, mark not reaching posterior margin. Long white pile and pruinosity on abdominal segment 9. Anal styles ferruginous with fuscous tips, reaching beyond dorsal beak. Gonocoxite IX ferruginous with white pile and pruinosity, gonapophysis VII castaneous, gonapophysis X piceous with long white pile near tip. Ovipositor sheath extending slightly beyond tip of dorsal beak and anal styles.

Measurements (mm).— N = 5 males or 1 females, mean (range). Length of body: male 33.0 (31.0–34.7), female 32.5; length of forewing: male 41.2 (39.2–43.4), female 43.2; width of forewing: male 14.6 (13.1–15.7), female 15.4; length of head: male 5.5 (5.0–5.9), female 6.1; width of head including eyes: male 16.2 (15.2–16.9), female 16.7; width of pronotum including suprahumeral plates: male 15.5 (14.5–16.4), female 16.9; width of mesonotum: male 12.3 (11.9–13.0), female 13.5.
