Amazopimpla errabunda Sääksjärvi, Gauld & Jussila , sp.n. ( Figs. 2 , 6 )

MATERIAL EXAMINED: Holotype female: Peru, Loreto, Boqueron Abad 26.IX.1962, M. J. Schunke leg. ( BMNH). Paratype male: Peru, Dept. of Loreto, Iquitos area, Allpahuayo, 16.VII­2.VIII.2000, Varillal forest, Ilari E. Sääksjärvi & Andres Marmol Burgos et al. leg., Malaise trap (G2/10) ( ZMUT).

HOLOTYPE FEMALE: Mandible proximally rather evenly tapered, with upper tooth slightly longer than lower tooth. Malar space about 0.5 times basal mandibular width. Face polished, with some shallow setiferous punctures, about 1.4 times as wide as medially high. Length­to­thickness ratio of first flagellomere about 6.2. Head, in dorsal view, with gena distinctly narrowed but not rounded behind eye; posterior ocellus separated from compound eye by about 1.3 times its own maximum diameter; ocelli forming an equilateral triangle; occipital carina present ventrally as a vestige, joining hypostomal carina.

Pronotum bare, in profile rather short and mediodorsally rather short. Mesoscutum anteriorly with some orange hairs (otherwise bare), moderately rounded, with notauli distinctly impressed. Mesopleuron highly polished, with some setiferous punctures, with some light hairs; epicnemial carina ventrally high (otherwise low), reaching almost the hind edge of pronotum; epicnemium with a secondary carina adjacent to front coxa. Metapleuron very weakly convex, smooth and polished, with some setiferous punctures; submetapleural carina anteriorly interrupted, otherwise rather distinct. Propodeum in profile rather weakly declivous, smooth and laterally with some setiferous punctures; pleural carina very weak, almost absent. Fore wing length about 12.0 mm; vein 3rs­m complete, enclosing an obliquely rhombic areolet. Hind wing with abscissa of Cu1 between M and cu­a somewhat bowed, about 6.7 times as long as cu­a. Length of hind femur about 5.5 times its breadth. Metasoma quite stout; tergite 1 about 1.3 times as long as posteriorly broad, with a smooth central area that is defined by distinct lateromedian carinae up to apex, which is interrupted centrally, with lateral carinae strong, somewhat interrupted centrally; tergite 1 in profile dorsally evenly convex; tergite 2 about 0.8 times as long as posteriorly broad, with a distinct central area, lateral oblique and posterior transverse grooves polished, without punctures; tergites 3­5 with a distinct central area, the surrounding furrows rather smooth. Ovipositor projecting beyond apex of metasoma by about 4.2 times length of hind tibia; (ovipositor shaft broken); ovipositor subapically subcylindrical; apex of lower valve dorsolaterally expanded to partially enclose the upper valve, bearing about seven rather oblique apical teeth and a weak scabrous furrow; apex of upper valve with about eight dorsal teeth.

Head and first five flagellomeres of antenna (partly broken) black; mesosoma orange except for dark pronotum (however dorsal and apical margins orange); metasoma orange with tergites from 4 to apex blackish (apical margins orange). Legs orange; coxae, trochantera, trochantelli, femora (hind femur only partly), hind tibia, hind tarsomeres dark; fore coxa and trochantera partly whitish. Wings yellowish, fore wing with apex distal 3 rsm blackish, and with a blackish median band extending from Rs & M to level of middle of pterostigma; hind wing with a blackish subapical dorsal spot; pterostigma black.

THE PARATYPE MALE resembles the holotype female but its pleural carina is clearly stronger, hind femur is broader (length­to­breadth ratio 4.6), mesasoma wholly black, fore and middle coxae, trochantera and trochantelli whitish, and all femora and hind trochantera and trochantelli orange; the fore wing length is about 9.0 mm.

DIAGNOSIS: A. errabunda can be distinguished most easily from all the other known species in the genus by its ventrally broadened, crest­like epicnemial carina. A. errabunda resembles A. lutea , A. farallonensis and A. matogrossoensis in structure by having the submetapleural carina, but differs from all of them by having strong lateromedian carinae extending up to apex in the first tergite.

ETYMOLOGY: The specific name refers to the apparent rarity of this species.
