Diagnosis

Handaoia cuscoensis Bordera sp. nov. can be distinguished from all other New World species by the combination of the following characters: apophysis of propodeum high, subtriangular with blunt tip ( Fig. 2F View Fig , arrow); juxtacoxal carina absent ( Fig. 2C View Fig ); area externa of propodeum confluent with area dentipara ( Fig. 1A View Fig ); hind coxa tinged with white ( Fig. 2A View Fig ).

Etymology

The name of the species refers to the Department of Cusco ( Peru), the type locality region.

Material examined

Only known from the holotype female.

Holotype PERU • ♀; Quincemil , 750 m nr. Marcapata; 10–15 Nov. 1962; Luis Peña leg.; AEIC.

Description

Female

MEASUREMENTS. Body length (without ovipositor) 3.8 mm. Fore wing 2.9 mm long.

HEAD. Very finely and densely granulate, matt, distinctly narrowed behind eyes, occiput very concave centrally in dorsal view ( Fig. 2E View Fig ); gena about 0.15 × length of eye in dorsal view; posterior ocellus separated from eye by 1.43 × its own maximum diameter; distance between posterior ocelli 1.14 × maximum ocellar diameter ( Fig. 2E View Fig ); occipital carina gently V-shaped medially; malar space 1.33 × basal width of mandible; face moderately swollen medially ( Fig. 2B View Fig ); clypeus very weakly convex, almost flat, finely and slightly granulate with scattered punctures, its apex weakly rounded, about 2.3× as wide as high; mandible slightly tapered to apex, ventral tooth of mandible a little shorter than upper tooth; maxillary palp reaching at most ¾ length of mesosternum; flagellum widened in middle, tapered towards apex, flagellomeres 8–19 flattened ventrally ( Fig. 1A View Fig ); flagellum with 20 segments, lengththickness ratios: 1 st segment = 5.64, 2 nd = 6.55 and 10 th = 1.08.

MESOSOMA. Very finely and densely granulate, matt ( Fig. 2D View Fig ); mesoscutum conspicuously convex, notauli absent ( Fig. 2E View Fig ); scutellum moderately convex, without lateral carinae; sternaulus very short and weak, as a wide V-shaped depression anteriorly, reaching at most 0.3× length of mesopleuron ( Fig. 2D View Fig ); juxtacoxal carina barely indicated anteriorly ( Fig. 2C View Fig ); propodeum ( Fig. 1A View Fig ) with mostly weak carinae; area superomedia confluent with area basalis and separated from area petiolaris; area externa and area dentipara confluent; area spiracularis confluent with area lateralis; area dentipara section of lateral longitudinal carina very weak, partly absent; posterior transverse carina strong, forming elevate apophysis joining lateral longitudinal carina, apophysis subtriangular, with blunt tip ( Fig. 2D, F View Fig , arrow). Length of hind femur about 4.4 × its height. Hind wing with vein cu-a 0.73 as long as abscissa of CU between M and cu-a.

METASOMA. Tergite I ( Figs 1A View Fig , 2G View Fig ) finely granulate and very weakly strigose laterally, matt, 2.5× as long as its maximum width; lateromedian longitudinal carina absent; lateral longitudinal carina complete; tergite II ( Fig. 2G View Fig ) shallowly granulate, shiny, glabrous; remaining tergites ( Fig. 2G View Fig ) smooth and shiny with inconspicuous dense setiferous punctures. Ovipositor sheath about 0.4× as long as hind tibia.

COLOUR. Head ( Fig. 2A–B, D–E View Fig ) light orange; antenna with scape and pedicel light brown, flagellum dark brown, distal part of flagellomere 4 to flagellomere 7 dorsally white ( Fig. 2A View Fig ). Mesosoma ( Fig. 2D– E View Fig ) light orange. Metasoma ( Fig. 2G View Fig ) mostly brown, tergites I–II and anterior part of IV light orange. Legs ( Fig. 2A View Fig ) mostly light orange, distal tarsomeres, dark brown, fore and mid coxae, trochanters and trochantelli white, hind coxa white proximally, dark brown distally. Wings ( Fig. 2A View Fig ) slightly evenly infuscate.
