The genus
|
|
|
Antenna | shortened; flagellomeres strongly transverse | not shortened; flagellomeres weakly transverse to elongate |
Propodeum and metapleuron | with coarse irregular rugae | without rugae |
Sub-basal cell in hind wing | unusually long and narrow | not especially narrow |
First metasomal segment | round in cross-section, very slender, about 6.6 times as long as posteriorly broad | trapeziform centrally in cross-section, 3.3–5.0 times as long as posteriorly broad |
Glymma | lacking | present |
A new species from southern and southeast Brazil,
1 | Fore wing with first and second abscissae of radius meeting at obtuse angle (Fig. |
|
– | Fore wing with first and second abscissae of radius meeting at right angle. |
|
2 | Hind wing with mediella (M+Cu) very weakly arcuate and subparallel to submediella (1A), thus the sub-basal cell is unusually long, 5.0–6.0 times as long as broad (Fig. |
|
– | Hind wing with mediella (M+Cu) distinctly arcuate; sub-basal cell not unusually long, 2.8–4.0 times as long as broad. Small to moderately large species with body length usually 4.0 to 10.0 mm |
|
3 | First metasomal segment round in cross-section, without glymma. Metapleuron and dorsolateral area of propodeum with coarse irregular rugae. Fore wing with intercubitus about twice as long as abscissa of cubitus between intercubitus and second recurrent vein. Hind wing with nervellus slightly inclivous or vertical. Female with hind femur strongly clavate. Ovipositor with shallow dorsal subapical depression; sheath about 1.4 times as long as first tergite |
|
– | First metasomal segment trapeziform in cross-section, with a deep glymma (Figs |
|
Head rounded posterior to eyes in dorsal view (Fig.
Notaulus rather long, weakly impressed, with a strong longitudinal wrinkle and sometimes with weak adjacent wrinkles (Figs
Fore wing (Fig.
Hind femur slightly clavate (Fig.
First metasomal segment very slender, 5.4 times as long as posteriorly broad, trapeziform in cross-section, arcuate in lateral view, smooth, with glymma situated somewhat behind its middle (Fig.
Head black; palpi, lower half of clypeus and mandible (except black teeth) brownish yellow. Antenna with scape and pedicel dark brown, flagellum black. Mesosoma (including tegula) black. Pterostigma pale brown. Legs brownish yellow; all coxae black; trochanters brown to brownish black; fore and mid femora brownish; hind femur brown, on lower and inner sides brownish black. Metasomal tergite 1 black, following tergites brown. Wings infumate with yellow-brown.
The male from São Paulo has metapleuron almost entirely covered with fine vertical wrinkles; dorsolateral area of propodeum with punctures mostly indistinct because of numerous fine wrinkles; basal area rather indistinct (basal longitudinal carinae weak); apical area hexagonal (apical longitudinal carinae ending anteriorly far from the posterior end of basal longitudinal carinae), impunctate; and nervellus less inclivous.
Holotype female (
Paratypes. 1 male (
Southern and southeast Brazil (Rio de Janeiro, São Paulo, Paraná).
The new species is named in honour of Gerald Durrell (1925–1995), a well-known British naturalist and author of many popular books about animals.
