Leschenaultia andarae  sp. n.

( Figs 6–9View FIGURES 6–8View FIGURES 9–14, 15View FIGURES 15–23)

Recognition. Leschenaultia andarae  sp. n. and L. bigoti  differ from all other species of Leschenaultia  by having grayish-yellow pruinosity on the head. These two species share the following combination of characteristics: syntergite 1+2 and tergite 3 with a few pairs of short median marginal setae; tergite 4 with a row of stout median marginal setae of varying lengths, with shorter setae situated in the middle; tergites 3 and 4 with a group of short discal setae. Leschenaultia andarae  sp. n. can be differentiated from L. bigoti  by first flagellomere about 2.5x length of pedicel and cercus slightly thinner and longer in profile (see Toma & Guimarães 2002: fig. 48).

Description. Male. Body length: 14.63 mm; wing length: 13.47 mm.

Coloration. Vertex and frontal vitta dark brown, ocellar triangle darker; fronto-orbital plate and apical third of parafacial dark brown; the rest of parafacial, face, facial ridge and gena reddish-brown; head with grayish-yellow pruinosity when viewed from certain angles; antenna dark brown, apex of scape yellowish; palpus yellowishorange, proboscis brown; thorax dark brown in ground color, except part of anepimeron, meron, suture between anepisternum and katepisternum, katatergite, katepimeron and anatergite brown; supra-alar area, postalar wall and greater ampulla yellowish; thorax with moderate gray pruinosity; scutum in posterodorsal view with five black stripes, two outside of the dorsocentral rows (presutural stripes triangular), two outside of the acrostichal rows, not reaching posterior margin of scutum, and one between the acrostichal rows; scutellum dark brown with light brown pruinosity; wing veins light yellowish-brown, yellower basally; calypters brown with brown pruinosity; halter light brown except basal portion yellow; legs dark brown; abdomen dark brown in ground color, with faint light brown pruinosity.

Head. Vertex about 0.23x head width in dorsal view; inner vertical seta about 1.35x length of reclinate orbital seta; ocellar seta about 0.7x length of reclinate orbital seta; fronto-orbital plate with about 10 frontal setae, two of them situated below level of lower margin of pedicel; first flagellomere about 2.5x length of pedicel; facial ridge with a row of supravibrissal setae on lower 0.6 of its length, setae 0.2–0.4x length of vibrissa; subvibrissal ridge with three to five setae, 0.33–0.42x length of vibrissa.

Thorax. Posteriormost postsutural acrostichal seta about 1.5x length of preceding seta; posteriormost postsutural dorsocentral seta about 1.6x length of preceding seta; posteriormost postsutural intra-alar setae about 1.8x length of preceding seta; second and third postsutural supra-alar setae almost equal in length and about twice length of first postsutural supra-alar seta; mid tibia with six strong anterodorsal setae, the longest about 0.4x length of tibia and about 1.7x length of anteroventral seta.

Abdomen. Syntergite 1+2 and tergite 3 with a few pairs of short median marginal setae; tergite 4 with a row of stout median marginal setae of varying sizes, with shorter setae in the middle; tergites 3 and 4 with a group of short discal setae; tergite 5 with many long discal setae. Terminalia ( Figs 9View FIGURES 9–14, 15View FIGURES 15–23). Cercus in profile tapering to apex, anteriorly gently curved backward, curvature slightly more accentuated in apical third, posteriorly almost straight to apical third, then smoothly bending backward, and slightly thinner and longer than in L. bigoti  ; surstylus in profile with rounded apex and about 0.8x length of cercus.

Female. Unknown.

Geographic distribution. Brazil (Mato Grosso).

Type material.

Etymology. The specific epithet is in honor of Carmen Andara, a colleague from the biology department at Universidad de Carabobo, Venezuela.
