Gondwanocentrus humphriesi Butcher & Quicke sp. nov.

Material examined. 1 Female, CHILE, Region ×, Parc Nacional Puyehue Anticura Sendero Repucura, sweeping in Nothofagus /Cusqueira forest, 447m, 17.ii.2005, 40º 39’ 53”S 70º 10’ 02”W.

Description. Body length 2.8 mm, fore wing 2.6 mm and exserted part of ovipositor 0.5 mm. Flagellum with 14 segments. Terminal flagellomere 1.5 × wider than 1st. Apical three flagellar segments distinctly swollen and wider than rest of flagellum. First flagellomere 1.1 × longer than both the 2nd and 3rd separately; 3.6 × longer than wide. Face without midlongitudinal ridge, strongly transversely striate. Frons, occiput and temples coarsely rugose. Distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 3: 1: 3. Temples wide and rounded. Pronotum forming a short but distinct neck. Mesosoma 1.7 × longer than high, largely setose ( Fig. 6 ). Forewing: pterostigma 4 × longer than maximally wide; lengths of r-rs:3RSa:3RSb = 1.0:2.7:3.7; vein 1CUa: 1Cub = 1.0: 2.1 ( Fig. 5 ). Hind wing: vein M+CU 1.25 × longer than 1-M; vein m-cu slightly postfurcal. Fore femur with fine transverse sculpture, 4.5 × longer than maximally deep. Fore tibia 1.1 × longer than fore tarsus. Fore basitarsus 5 × longer than deep, 0.33 × length of whole tarsus. Hind coxa coarsely sculptured, transversely striate posterodorsally. Hind femur: tibia: tarsus: basitarsus = 0.85: 1.0: 0.85: 0.3. Hind basitarsus 0.25 × length of whole tarsus. First metasomal tergite longitudinally striate, basally with curved carinae that do not meet medially. 2nd and 3rd tergites largely coriaceous but with sculpture tending to form longitudinal parallel lines. 2nd tergite with a very small mid-basal triangular area that is produced medially into a weak but distinct mid-longitudinal carina.

Colour. Largely black; face, top of head, mesoscutum largely (except margins) red-brown; legs and palps yellowish; wings clear with pale brown venation.

Male. Unknown.

Biology. Unknown.

Etymology. Named in honour of the delightfully inquisitorial Mr John Humphries, who during an interview with the junior author for the BBC Radio 4 Today Programme suggested it might be nice to have a species named after himself.
