Ungla annulata Navás, 1914. Broteria (Zool.) 12: 224-225; “República Argentina: Huasán, Febrero de 1912 (Bruch.)". Stange 1967: 41 (catalog); Adams 1975: 169 (synonym of Hypochrysa argentina Navás); Penny 1977: 16 (list, as synonym of H. argentina ); Brooks and Barnard 1990: 276 (tax, as synonym of U. argentina ); Monserrat 1985: 240 (type); Monserrat and Freitas 2005: 165 (tax, as synonym of U. argentina ); Oswald 2015 (catalog, as synonym of U. argentina ). Lectotype (Figs 95, 96): MZBS, female (examined). Monserrat (1985: 240) reported a type from the MZBS; it is a female, studied by Adams (1975: 169). We (CAT) examined the specimen in 2010; to help stabilize the nomenclature of Ungla , here this specimen is designated as the lectotype (des. CAT). Type locality: The type locality “Huasán” is located in northwestern Argentina - Andalgalá, Catamarca (27°34'S, 66°19'W, ~1100 m).

Syntypes (Fig. 97). MACN. Several specimens from the type locality and the approximate collection dates (Dec. 15-31, 1928, Jan 20, 1929) are in the MACN. Any of those specimens that carry dates from Jan 1 to Jan 20 could be considered syntypes. Currently, one of the specimens carries lectotype and type labels, but none of these labels are in Navás’ hand, and it is not clear which of the specimens in the MACN Navás may have used. Stange (1967: 35) noted a male and González Olazo (1996: 378) noted a female that they each considered as the holotype. Given that Navás clearly had more than one specimen, we suggest that a lectotype be designated after the full series of syntypes has been studied carefully. Support for synonymy. González Olazo (1996: 378) recognized that this species belongs in the genus Ungla , and he listed it as synonymous with U. argentina . However, it is not clear what specimens or information he considered to support his synonymy. Here, in the absence of a confirmed type specimen for C. lurida , we used Navás’ description of the external features and Adams’ unpublished notes and drawings from specimens in the MACN. These specimens had been collected at the type locality during the period mentioned in the original description and during the month earlier. Adams apparently considered these specimens as representative of the C. lurida type series.

Diagnosis.

This species, along with U. argentina , can be differentiated from most other Ungla species by a number of features: brownish coloration, longitudinal wing veins with alternating white or cream-colored and dark brown or black, often with dark patches at intersections. It differs from U. argentina in usually expressing the following external features: vertex with distinct, inverted U-shaped marking, usually divided mesally, with anterior markings running forward, but not extending beyond scapes to the frons; frons pale (sometimes whitish), unmarked; wing membrane irridescent, wings with longitudinal and some transverse veins alternately white and black, distal ones, dark (see Figs 98, 99c, d, for comparison of distal venation with U. argentina ). In the males of both species, the terminus of S8+9 has large, but simple (unflanged) setae, and the gonosaccus is bilobed, with lobes broadly connected. In U. annulata , the abdominal spiracles are greatly enlarged - a trait that clearly separates it from U. argentina . Also, the ventral apodeme of the U. annulata ectoproct extends distally beyond the terminus of the segment, a feature that does not occur in U. argentina .

Redescription.

Head: vertex cream-colored to tan, with dark reddish brown "U-shaped marking" prominent, usually broken mesally, with pigmented coloration extending forward from tips of marking to area between scapes, not extending to frons; anteromesal margin of antennal fossa also with elongated, reddish brown to brown marking extending to mesal margin of scapes; gena, lateral margins of the clypeus with dark brown stripe. Antenna with scape cream-colored to tan with diffuse, brown, longitudinal mark or marks laterally, pedicel mostly brown or light brown, flagellum tinged with brown basally, tan distally; basal palpomeres pale, mesal palpomeres brown, terminal segments pale with brown basally.

Prothorax brown to dark brown laterally, tan to light brown mesally, with transverse furrow in posterior region, not reaching lateral margins, with short, dark setae throughout. Mesothorax, metathorax brown to dark brown, with darker brown markings. Measurements: head width: 1.3-1.4 mm; ratio head width: eye width: 2.3-2.5: 1; prothorax width: 1.0-1.2 mm; prothorax length: 0.7 mm.

Forewing, hindwing broad to very moderately narrow, with apices rounded (forewing) to rounded or slightly subacute (hindwing), venation slender to slightly robust; alar membrane hyaline, with suffusion light, often obscured by reflection; stigma light brown, opaque, with four to five black crossveins below surrounded by dark brown marks; longitudinal veins with alternate creamy and dark markings (usually dark brown at intersections with dark veins and cream-colored between intersections); transverse veins, gradate veins, crossveins dark. Forewing 10.2-11.6 mm long, 3.7-4.3 mm wide (ratio, L: W = 2.7-3.0: 1); height of tallest costal cell 0.7-0.9 mm (cell number 3-6); first intramedian cell ovate, 0.8-0.9 mm long; 9-10 radial cells (closed cells between R and Rs); third gradate cell 1.0-1.2 mm long, 0.4-0.5 mm wide (ratio, L: W = 2.6-3.2: 1); fourth gradate cell 0.9-1.1 mm long, 0.4-0.5 mm wide (ratio, L: W = 2.2-3.2: 1); 3-4 Banksian cells (b cells), 4 b’ cells; 3-5 inner gradates, 5-6 outer gradates. Hindwing 9.1-10.4 mm long, 3.0-3.4 mm wide (ratio, L: W = 3.0-3.1: 1), 9-10 radial cells, 3 b (Banksian) cells, 4 b’ cells, 3-5 inner gradates, 4-6 outer gradates.

Male. Abdomen with greatly enlarged spiracles, with large flaps on opening (e.g., A7: spiracle diameter ~0.30 × length of sternite); T9+ectoproct short, rounded posterodorsally, with dorsal invagination extending ~3/4 distance to anterior margin of T9, lateral margins of invagination straight; ventral margin of T9+ect sclerotized through out, terminus extending distomesally as distinct knob; callus cerci large, ovate, entire margin lightly sclerotized, sclerotization contiguous with sclerotization along posteroventral margin of segment; subanal plate small, delicate, with patch of one to eight irregularly placed setae. S8, S9 fused, fusion demarcated; dorsal margin with light sclerotization, heavier throughout terminal ~1/5th of S8+9, terminal setae robust, not flanged or otherwise modified. Gonarcus with bridge slender, lateral apodemes slightly expanded, rounded distally, process on side of lateral apodeme bent perpendicularly (lateral view) and slightly inward (frontal view) from gonarcal arm; mediuncus long, narrow, with dorsal margin slightly bowed; gonosaccus distinctly bilobed, with lobes broadly connected mesally; each lobe with large patch of gonosetae on enlarged bases - anterobasal gonosetae smaller, shorter, on smaller bases than posterodistal gonosetae; hypandrium internum U-shaped with arms straight (frontal view), bending upward (lateral view), comes hook-shaped.

Variation.

The U. annulata specimens that we examined varied in size and the depth of the dark markings on the head and body and the degree of white and black on the wing veins. The male abdominal and genital characteristics were consistent among specimens.

The above specimen from La Rioja (MSNG) bears a red type label with the name " Cintameva giacamellina Nav." handwritten by Navás. Apparenly, the name was never published; it is not listed by Oswald (2015). We identified the specimen as a female of U. annulata .
