Figs 1E, 7, 9A
Diagnosis
Handaoia ruizcancinoi Bordera sp. nov. can be distinguished from all other New World species by the combination of the following characters: apophysis of propodeum conspicuously high, subtriangular with blunt tip (Fig. 7H, arrow); juxtacoxal carina weak but complete, joining submetapleural carina at its anterior part (Fig. 7G, arrow); inner side of area externa about 7.0× as long as inner side of area dentipara (Fig. 1E).
Etymology
The species is named in honour of Dr Enrique Ruiz Cancino from Universidad Autónoma de Tamaulipas (Mexico), in recognition of his contribution to the study of the Ichneumonidae of Mexico. A noun in the genitive case.
Material examined
Known only from the holotype female.
Holotype MEXICO • ♀; Tamaulipas, Ocampo, J. de Manantiales; T. Amarillas; 13 May 1995; J. Coronado, S. Nino and C. Hernández leg.; CEUA.
Description
Female
MEASUREMENTS. Body length (without ovipositor) 4.0 mm. Fore wing about 3.0 mm long.
HEAD. Finely granulate, matt, strongly narrowed behind eyes, occiput very concave centrally in dorsal view (Fig. 7B–D); gena 0.14 × length of eye in dorsal view; posterior ocellus separated from eye by 1.55 × its maximum diameter; distance between posterior ocelli 1.27 × maximum ocellar diameter; occipital carina gently V-shaped medially (Fig. 7D); malar space 1.3× basal width of mandible; face conspicuously swollen medially (Fig. 7B); clypeus (Fig. 7B) quite convex, gently granulate with scattered coarse punctures, apex slightly rounded, about 1.8 × as wide as high; mandible quite tapered to apex, ventral tooth of mandible a little shorter than upper tooth; flagellum widened in middle, tapered towards apex, flagellomeres 8–18 flattened ventrally; flagellum with 20 segments, length-thickness ratios: 1 st segment = 4.1, 2 nd = 3.27 and 10 th = 0.72.
MESOSOMA. Finely granulate and matt (Fig. 7A, C–D); mesoscutum slightly convex, almost flat posteriorly; notauli moderately deep over 0.7× length of mesoscutum (Fig. 7D); scutellum moderately convex, without lateral carinae; sternaulus as a wide V-shaped depression anteriorly, reaching about 0.3× the length of mesopleuron (Fig. 7C); juxtacoxal carina weak but complete, joining submetapleural carina at its anterior part (Fig. 7G, arrow); propodeum (Figs 1E, 7C, H) with strong and conspicuous carinae; area superomedia confluent with area basalis and separated from area petiolaris; inner side of area externa about 7.0× as long as inner side of area dentipara; inner side of area dentipara about 0.3× length of outer side; area spiracularis confluent with area lateralis; posterior transverse carina strong, forming an elevated apophysis joining lateral longitudinal carina, apophysis subtriangular with blunt tip (Fig. 7C, H, arrow). Length of hind femur 3.9× its height. Hind wing with vein cu-a 0.77 × as long as abscissa of CU between M and cu-a.
METASOMA. Tergite I (Fig. 7E) finely granulate, shiny, strigose laterally, about 2.4× as long as its maximum width; lateromedian longitudinal carina moderately strong, reaching posterior 0.8× length of tergite; lateral longitudinal carina present from spiracle to posterior margin of postpetiole; tergite II (Fig. 7F) shiny, smooth and almost glabrous; remaining tergites (Fig. 7F) smooth and shiny, with short and moderately dense setiferous punctures. Ovipositor sheath about 0.5× as long as hind tibia.
COLOUR. Head (Fig. 7B–D) brown, darker dorsally, lighter ventrally, mandibular teeth and labrum dark brown; antenna with scape, pedicel and first flagellomere light brown, remaining flagellomeres dark brown, flagellomeres 5–7 dorsally white (Fig. 7A). Mesosoma (Fig. 7A, C) brown, more infuscate ventrally. Metasoma (Fig. 7E–F) dark brown. Legs (Fig. 7A) mostly dark brown; fore and mid coxae and trochanters, and hind trochanter, white. Wings (Fig. 7A) evenly infuscate.
Male
Unknown.
