Habronyx (Camposcopus) flavus Alvarado , new species

(Figs. 1–3)

Holotype: ♀, “ PERÚ: AM [Amazonas], Abra - Patricia [Protected Area], 19.viii.2012 0 5o 41’36’’S/ 77o48’41.9’’W, 2362 m, yellow [pan] trap, J. Suárez & P. Sánchez” ( MUSM).

Paratypes: ♀, same data as holotype, except 12.xi.2012 and Malaise trap”; and ♀, “ ECUADOR: Napo, Est. Biol. [Estación biológica] Yanayacu, 2000m 0 0o 34’20”[S]/ 77º52’20”[W] 21–24.xi.2006, C. Castillo” ( MUSM).

Diagnosis. This species can be distinguish from the other Neotropical taxa of its subgenus by the coloration of the legs, especially evident on the yellow of the metatibia grading to dark brown proximally in H. flavus , while the metatibia is blackish grading to dark brown proximally in H. ariasae and is entirely black in H. carmonai .

Description. Female: Fore wing length 14 mm. The paratypes are slightly smaller, with fore wing lengths of 7.8–13mm.

PLATE 1 FIGURES 1–3. Details of Habronyx (Camposcopus) flavus Alvarado , new species. 1. Lateral habitus (scale = 1 mm) 2. Facial view 3. Mesosoma, in lateral view.

Head. Mandibles stout, upper tooth stouter than, and about twice as long as lower tooth; lower face rather weakly narrowed ventrally with width across clypeal sulcus about 0.7x width across base of antennal toruli; frons areolate-rugose, with weak median vertical carina; lateral ocellus separated from compound eye by 1.7–1.8x ocellar diameter; distance between ocelli 1.1–1.3x ocellar diameter; gena, in lateral view (measured perpendicularly to torulus), 0.8x as wide as compound eyes; gena punctate, smooth between punctures, in upper area coarsely punctate (punctures separated by 0.1–0.3x a puncture width) grading to sparsely punctate in lower area (punctures separated by 2– 3 x a puncture width), next to compound eyes smooth; 36 flagellomeres in paratype, vide Comments, infra).

Mesosoma. Pronotum dorsally punctulate-reticulate grading ventrally to striate; epomia present, upper third diverging straight up from front margin, and then forming a rounded corner as it curves back towards front margin; mesoscutum punctulate-reticulate; notauli distinct, becoming less so in posterior half of mesoscutum; mesoscutellum slightly concave, punctulate-reticulate, with distinct lateral carinae; mesopleuron punctate ventrally, striate dorsally; sternal region punctate. Metapleuron and propodeum reticulate. Fore wing with distal abscissa of Rs 2.0x length of Rs+2r; 2+3rs-m 1.3x length of M between 2+3rs-m and 2m-cu.

Metasoma. Tergite I 0.9–1.0x length of metafemur, smooth and polished with isolated setae; tergite II+ smooth, with fairly thick, medium-length setae; ovipositor about 0.3x length of metatibia.

Color. Head black with face, gena ventrally, mandibles, a mark on the upper genal orbit and palpi yellow; antenna black with scape ventrally yellow. Mesosoma black with apical- dorsal tip with a yellow mark and tegula brownish dark; foreleg yellow with a ventral black mark on procoxal basal half; mid-leg yellow with procoxa black basally and infuscate apically; hind leg with coxa black, trochanter and trochantellus yellow, femur reddish brown, tibia yellowish grading to dark brown proximally, and, basitarsus yellowish with distal third and remaining tarsomeres black. Wings uniformly infuscate, pterostigma brownish. Metasoma with tergite I yellow, dorsally reddish brown; tergite II yellowish narrowly black dorsally; tergite III reddish brown; terguite IV reddish brown on proximal half grading to black; and with tergites V+ black. Ovipositor sheath yellow.

♂: Unknown.

Etymology. The specific epithet flavus , meaning “yellow”, is a reference to the coloration of the hind trochanter and trochantellus.

Comments. The paratypes are considerably smaller, with a fore wing length of 7.8 and 9.1 mm, and differ from the holotype in the following aspects: antenna with 36 flagellomeres, mesopleuron centrally smooth; ovipositor longer than 0.5x length of metatibia and pro- and mesocoxae completely black. The smaller specimen, from Ecuador, has the meso- and metacoxae infuscate basally and grading to yellow distally.

This species was collected in a humid tropical premontane forest on the northeastern slopes of the Andes (Fig. 16). This is the first record of a species of this subgenus in South America and the one with the most austral distribution.
