Habronyx (Habronyx) saqsaywaman Alvarado , new species

(Figs. 13–15)

Holotype: ♀, “Cusco Sacsayhuaman 3585 m 3.v.77 col. R. Garcia” ( MUSM).

Diagnosis. This species can be distinguished from other Neotropical congeners by the coloration of the hind tibia entirely black.

Description. Female: Fore wing length 12.4 mm.

Head. Mandibles stout, upper tooth stouter than, and about twice as long as lower tooth; lower face with strong punctures, centrally flat, rather weakly narrowed ventrally with width across clypeal sulcus about 0.7x width across base of antennal toruli; clypeus convex basally and concave apically, smooth with isolated punctures; frons areolate-rugose, with weak median vertical carina; lateral ocellus separated from compound eye by 2.3x ocellar diameter; distance between ocelli 1.8x ocellar diameter; gena, in lateral view (measured perpendicularly to torulus), 1.3x as wide as compound eyes, gena punctate-reticulate grading to smooth between punctures on lower quarter, and next to compound eyes smooth; antenna with 40 flagellomeres.

Mesosoma. Pronotum areolate-rugulose grading by lower quarter to striate-rugose; epomia present, upper third diverging from front margin and then forming a rounded corner as it curves back towards front margin; mesoscutum areolate-rugulose; notauli not distinct; mesoscutellum convex, reticulate, lateral carinae distinct reaching to the distal end; mesopleuron punctulate-reticulate. Metapleuron and propodeum reticulate. Fore wing with distal abscissa of Rs 1.6x length of Rs+2r; 2+3rs-m 1.1x length of M between 2+3rs-m and 2m-cu. Hind wing with distal abscissa of Cu1 sclerotized throughout.

Metasoma. Tergite I 0.8x length metafemur, smooth with isolated setae; tergite II+ smooth, with fairly thick, medium-length setae; ovipositor about 0.6x length of metatibia.

Color. Head black with lower face and clypeus yellow, except black marks from tentorial pits reaching to below each antennal socket and on clypeus two marks shaped as half round on each side of it (like in Fig.14), and scape ventrally with a yellow mark on base; and, a spot on vertex (next to compound eyes) and on inner margin of gena (next to compound eyes) orange.

Mesosoma black except fore leg with femur brownish (except dorsally on apical 3/4) orange, tibia brownish except orange ventrally, and tarsomeres orange; mid leg with tibia and tarsomeres brownish; and hind leg with basal sixth of basitarsis orange. Metasoma black except with apical half of tergite I, tergite II (narrowly black dorsally on anterior 2/3), tergite III and basally tergite IV orange. Ovipositor sheath black.

♂: Unknown.

Etymology. The specific epithet saqsaywaman is the Quechua word for Sacsayhuaman, the type locality. The name is treated as a noun in apposition.
