Diagnosis

Handaoia urceus sp. nov. can be distinguished from all other New World species by the combination of the following characters: apophysis of propodeum as a low transverse rounded crest ( Fig. 8I View Fig , arrow); tergite II finely granulate ( Fig. 8D View Fig ); juxtacoxal carina strong anteriorly, weak posteriorly, joining submetapleural carina at its half length ( Fig. 8H View Fig , arrow); area externa of propodeum separated from area dentipara by strong carina ( Fig. 1F View Fig ); inner side of area externa about 8.0× as long as inner side of area dentipara ( Fig. 1F View Fig ).

Etymology

From the Latin for ‘pitcher’, named after the flask- or pitcher-shaped combined area basalis + superomedia. A noun in apposition.

Description

Female

MEASUREMENTS. Body length (without ovipositor) 4.3 mm. Fore wing 3.7 mm long.

HEAD. Finely granulate, matt, distinctly narrowed behind eyes, occiput very concave centrally in dorsal view ( Fig. 8B–C View Fig ); gena 0.22 × length of eye in dorsal view; posterior ocellus separated from eye by 1.0 × its maximum diameter; distance between posterior ocelli 1.0× maximum ocellar diameter ( Fig. 8C View Fig ); occipital carina gently V-shaped medially ( Fig. 8E View Fig ); malar space 1.44 × basal width of mandible; face moderately swollen medially ( Fig. 8B View Fig ); clypeus ( Fig. 8B View Fig ) weakly convex, gently granulate with scattered punctures, apex slightly rounded, about 1.6× as wide as high; mandible slightly tapered to apex, ventral tooth approximately same length as upper tooth; maxillary palp long, almost reaching middle coxa; flagellum widened in middle, tapered towards apex ( Fig. 8A View Fig ), flagellomeres 8–18 flattened ventrally; flagellum with 22 segments, length-thickness ratios: 1 st segment = 4.9, 2 nd = 6.1 and 10 th = 1.13.

MESOSOMA. Finely granulate and matt ( Fig. 8E, G View Fig ); mesoscutum ( Fig. 8E, G View Fig ) convex, notauli moderately deep anteriorly, reaching about 0.3 × distance to scuto-scutellar groove; scutellum moderately convex, without lateral carinae; sternaulus moderately deep, reaching about mid-point of mesopleuron ( Fig. 8G View Fig ); juxtacoxal carina strong anteriorly, weak posteriorly, joining submetapleural carina at mid length ( Fig. 8H View Fig , arrow); propodeum ( Figs 1F View Fig , 8I View Fig ) with strong and conspicuous carinae; area superomedia confluent with area basalis and separated from area petiolaris; inner side of area externa about 8.0 × as long as inner side of area dentipara; inner side of area dentipara 0.25 × length of outer side; area spiracularis confluent with area lateralis; posterior transverse carina strongly elevated, forming a low transverse crest joining lateral longitudinal carina ( Fig. 8I View Fig , arrow). Length of hind femur 4.2 × its height. Hind wing with vein cu-a about 1.0 × as long as abscissa of CU between M and cu-a.

METASOMA. Tergite I ( Figs 1F View Fig , 8D View Fig ) finely granulate, matt, about 1.70 × as long as its maximum width; postpetiole laterally and posteriorly tending to fine strigosity; lateromedian and lateral longitudinal carinae strong, reaching at least 0.8× length of tergite; tergite II ( Fig. 8D, F View Fig ) finely granulate, shiny; remaining tergites ( Fig. 8D, F View Fig ) smooth and shiny with inconspicuous setiferous punctures. Ovipositor sheath about 0.54× as long as hind tibia.

COLOUR. Head ( Fig. 8B–C View Fig ) dark brown tending to be more reddish on clypeus and mandibles; palpi light brown; antenna with scape, pedicel and flagellomeres I–II (III) light brown, remaining flagellomeres dark brown, distal part of flagellomere 4 to flagellomere 7 dorsally white ( Fig. 8A View Fig ). Mesosoma ( Fig. 8E– G View Fig ) entirely orange. Metasoma ( Fig. 8D–F View Fig ) with a gradient from orange at anterior of tergite I to dark brown on posterior tergites, posterior rim of tergites I–III yellowish. Legs ( Fig. 8A View Fig ) light brown, distal tarsomeres dark brown, fore and mid coxae, part of hind coxa and all trochanters and trochantelli lighter. Wings ( Fig. 8A View Fig ) slightly infuscate.
