Type material.— ARGENTINA. HOLOTYPE: male ( INHS), “ Tucuman / Dto. Trancas. Ruta 9 / ca. Trancas. 17–I–1988 / J.E. & M.S. Heath, Al / Sanborn & F. Noriega Coll. ” . PARATYPES: one male and one female ( MSHC) same data as holotype ; two male ( MSHC) “ Catamarca / Ruta 40. 1 km No. of / Rio Salado. 20–I–1988 / J.E. & M.S. Heath, Al / Sanborn & F. Noriega Coll. ” ; one male ( MSHC) “ La Rioja / Dto. San Blas de los / Sauces. Salicas / 20 Jan. 1988 / Heath / Sanborn-Noriega Coll.” .

Etymology. The species is named for northern distribution of the species compared to its congeners.

Diagnosis.— Male specimens of C. septentrionala sp. n. can be differentiated by the length of their opercula which reach to the middle of sternite III. The opercula of Chonosia longiopercula sp. n. extend to sternites V and VII, while the opercula of C. papa ( Berg, 1882) rev. stat., C. atrodorsalis , and C. crassipennis do not reach the posterior of sternite II. Females can be differentiated by their larger body size (about 30 mm) from C. atrodorsalis Torres, 1945 (about 24 mm) and C. trigonocelis Torres, 1945a (about 26 mm). The notch on the posterior of sternite VII of C. septentrionala sp. n. is circular, has parallel sides in C. longiopercula sp. n., has parallel sides posteriorly with a circular anterior terminus in C. papa , and the notch expands anteriorly into a tear drop shape in C. crassipennis (Walker, 1858) .

Mentum tawny, labium ferruginous medially, piceous laterally and on tip, reaching beyond posterior coxae. Gena tawny with central fuscous stripe between postclypeus and eye. Lorum ferruginous with tawny anterolateral corner. Long white and short silvery pile and white pruinosity on gena and lorum. Scape and pedicel ferruginous with tawny junction, flagellar segments piceous.

Thorax.—Pronotum ferruginous with tawny anterior margin and midline. Piceous on disc medial to paramedian fissures connected across midline, and on anterior, central and posterior disc between paramedian and lateral fissures. Posterior mark curving mediad fusing on midline. Ambient fissure mark extending lightly onto anterior midline of pronotal collar. Marks on anterior and central disc between lateral and ambient fissures. Lateral mark extends onto medial portion of pronotal collar lateral margin and along ambient fissure fusing with mark across posterior disc between posterior paramedian fissure and posterior lateral fissures. Pronotal collar tawny, fuscous along posterior margin and posterior margin of lateral angle. Pronotum covered with silvery pile. Mesonotum ferruginous with piceous submedian sigillae except central lateral portion along parapsidal suture. Mark in lateral sigillae extends onto posterolateral mesonotum. Medial mark extends posteriorly from anterior margin, expands to medial side of scutal depression, constricts between anterior arms of cruciform elevation, and terminates on anterior disc of cruciform elevation. Anterior arms of cruciform elevation with longitudinal fuscous mark on anterior surface. Wing groove ferruginous medially, tawny laterally. Short, silvery pile covering dorsum, white pruinosity laterally, between anterior arms of cruciform elevation, surrounding scutal depression, and within wing groove. Metanotum ferruginous with white pruinosity. Ventral thoracic plates fuscous except tawny lateral and posterior anepisternum 2 and epimeral lobe and ferruginous lateral anepimeron 2 and basisternum 3. Venter covered with long white pile and white pruinosity.

Forewing and hind wings.—Hyaline. Venation tawny proximally, becoming ferruginous distally with light infuscation along veins, fuscous between costa and radius + subcostal vein. Basal cell, cubital cell and proximal third of clavus clouded with tawny. Basal membrane reddish gray. White pruinosity in basal cell, along cubital cell, in proximal clavus. Hind wing venation tawny except ochraceous radius posterior, veins margined with infuscation. Vanal fold, anal cell 3, anal cell 2 along anal veins 2 and 3, anal cell 1 along anal vein 2 and proximal one fourth of anal vein 1, and proximal cubital and radial cell reddish gray, reddish in anal cells 2 and 3 distally margined with infuscation.

Median uncus lobe fuscous with parallel sided base, tapering to rounded terminus at about half its length, central ridge tawny. Anal styles tawny, fuscous centrally, extending beyond 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 curving to rounded medial notch.
