Ungla ivancruzi Freitas, 2007. Rev. bras. Entomol. 51: 414-415; "Minas Gerais, Sete Lagoas, EMBRAPA, CNPMS, Lab., 16.I.2007 (S. de Freitas)". Tauber et al. 2014: supplementary material (list); Oswald 2015 (catalog). Holotype. MZSP (?), male (examined, FS); holotype by original designation. The original description stated that the holotype was in the MZSP, but it has not been found there; it is at the Departamento de Fitossanidade, UNESP, Jaboticabal, São Paulo. The holotype and all the paratypes appear to have been reared in the laboratory; neither the conditions under which the adults were held, nor the age of the adults when they were preserved for study were mentioned.

Diagnosis.

Among Ungla species U. ivancruzi is unique in that the male has a broadly wedge-shaped S8+9 that is more typical of Chrysopodes than other Ungla males, which have S8+9 elongate and tapering. Nevertheless, we consider U. ivancruzi a good species of Ungla ; it expresses most of the diagnostic features of the genus, including the distinctive inverted U-shaped mark on the vertex, dorsal apodeme on the male T9+ect reduced so that it does not extend beneath T8, gonarcal arch rounded, with a narrow, elongate mediuncus attached dorsally, and a bilobed gonosaccus, with each lobe bearing a patch of elongate gonosetae. Ungla ivancruzi can be distinguished from other Ungla by its (i) light colored (not black or dark brown) palpi, (ii) reddish genal markings, (iii) narrow gonarcal arch with thin, elongate arms lacking a prominent frontal process, and (iv) gonosaccus with gonosetae relatively well-spaced, not abutting each other. At this time, U. ivancruzi is the only Ungla species known from Brazil. See original description by Freitas (2007) for additional images.

Redescription.

Head with vertex yellow, raised, smooth, shiny; inverted U-shaped mark red to reddish brown, broken anteromesally, not extending forward between antennae. Frons yellow, without marks; gena light reddish brown; maxillary palp pale, ultimate palpomere 1.5 times longer than anterior one; scape yellow with dorsomesal red mark that extends onto pedicel, base of flagellum; flagellomeres yellowish brown, with rows of black setae.

Thorax yellowish green, with distinct longitudinal cream-colored stripe mesally. Prothorax with pair of broad, dark reddish brown stripes laterally; transverse furrow in posterior region of segment, extending to lateral margins, with brown to black setae on areas marked with brown, golden setae on green areas. Mesonotum, metanotum with diffuse brown lateral marks. Measurements: head width: 1.3 mm; ratio head width: eye width: 2.3: 1; prothorax width: 1.0 mm, length: 0.6 mm.

Forewing, hindwing with rounded tip; membrane clear, hyaline, without fumose areas; stigma slightly opaque to light brown. Forewing with longitudinal veins green, marked with brown at intersections; transverse veins dark brown to black; transverse costal, radial, gradate veins black, without suffusion. Forewing with Rs sinuous; first intramedian cell ovate; basal inner gradate meeting Psm; 7.9-10.2 mm long, 3.4 mm wide (ratio, L: W = 2.9: 1); height of tallest costal cell 0.63 mm (cell number 5); width of first intramedian cell 0.65 mm; 9 radial cells (closed cells between R and Rs); third gradate cell 0.9 mm long, 0.4 mm wide (ratio, L: W = 2.3: 1); fourth gradate 0.4 mm long, 0.3 mm wide (ratio, L: W = 1.5: 1); 4 Banksian cells (b cells), 4 b’ cells; 3 inner gradates, 5 outer gradates. Hindwing 7.2-9.2 mm long, 3.0 mm wide (ratio, L: W = 3.0: 1), 9-11 radial cells, 3 Banksian (b) cells, 4 b’ cells, 3 inner gradates, 5 outer gradates.

Abdomen yellowish green, without spots. Male. T9+ect relatively long (~0.5 length of T7), almost straight dorsally, angulate at dorsal terminus, with dorsal invagination deep (~0.7 × dorsal length of T9+ect); margins, base of invagination rounded; abdominal spiracles small (e.g., A7: spiracle diameter ~0.09 × length of sternite); callus cerci large, round to oval, with 27-30 trichobotria; S8+9 fused, with line of fusion perceptible; dorsum tapering slightly throughout basal 3/4ths, abruptly through distal fourth; S8+9 length ~1.8x height, not much longer than S7 (1.4 ×); apex acute, not upturned, not elongated beyond T9+ect. Gonarcus thin, arched without angular bend (dorsal, frontal view), with S-shaped curve (lateral view); gonarcal bridge, arms slender throughout, thickened mesally, forming very small mesal process; arcessus long, curved dorsally, with pair of lateral rods internally, slightly splayed mesally, fusing distally, terminating in small beak; gonossacus bilobed, with two tufts of elongate, well-spaced gonosetae facing each other mesally; hypandrium internum V-shaped, small.

Female. See Freitas (2007).

Larvae and biology.

Immatures were reared, and the three instars are described ( Freitas 2007). The larvae are debris carriers; and eggs are laid in clusters.
