( Figs 9–12 View FIGURES 9 – 12 , 81 View FIGURES 78 – 81 )

Diagnosis. Body mostly honey yellow, antenna brown, stemmaticum and mid lobe of mesoscutum brown, metasomal terga 2 and 3 brown basally and yellowish apically; occipital carina complete dorsally, not meeting hypostomal carina ventrally; fore wing vein r-m present, second submarginal cell virtually square; hind wing vein RS gradually opening from wing margin from base, subtly curved downward at middle, vein m-cu absent; fore wing vein 1-CU1 longer than vein cu-a; metasomal tergite 3 granulate; first and second flagellomeres fused, division between segments faintly indicated.

Description of holotype. ♀, body length 4.0 mm, fore wing length 3.1 mm, antenna broken 5.2+ mm.

Head. Antennal segments 28+, antenna broken, third segment about as long as fourth segment, length of third and fourth antennal segments 3.3 and 3.5 times their width, respectively; length of maxillary palpi 0.9 times height of head; length of eye in dorsal view 3.8 times temple; head sculpturing shining granular-coriaceous; occipital carina complete dorsally, not reaching hypostomal carina ventrally; POL:OD:OOL = 4:4:5; face with relatively short setae, with weak median crest; clypeus distinctly protruding; oral opening (as synonym for hypoclypeal depression throughout the text) 0.35 times width of face; malar space only slightly longer than basal width of mandibles and 0.32 times eye height in frontal view; frons with two parallel and relatively long carina laterally; inner margin of compound eyes indented.

Mesosoma. Length of mesosoma 1.6 times its height; sculpturing mostly shining granular; pronotum mostly smooth with few crenulae anteriorly; precoxal sulcus extending throughout extension of mesopleuron and rugose; antescutal depression distinct, pronotal collar granular-coriaceous with two diverging carina connected to antescutal depression and forming an obtuse angle; mesoscutum densely granulate, broadly rugose anteriorly, without v shaped carina posteriorly; notauli narrow and deep medially, not traceable anteriorly, posteriorly meeting in a flat rugose area; scutellar sulcus smooth with one median longitudinal carina; propodeum with complete longitudinal carina and coarsely granulate anteriorly to weakly rugose posteriorly; ventral midline of mesopleuron set within deep crenulate sulcus.

Wings. Fore wing: vein r-m present, second submarginal cell virtually square, vein 2M as long as 3-RS; r:3- SR:SR1:2-SR:2-SR+M = 11:13:45:10:8; vein 1-SR+M weakly sinuate; vein 1-M slightly curved posteriorly; 1- CU1:2-CU1:cu-a = 11:23:4. Hind wing: vein cu-a short and reclivous; M+CU:1-M:1r-m = 7:20:4; vein RS weakly curved downward just distad middle; vein m-cu absent.

Legs. Tarsal claws simple, not pectinate, with some bristles basally, its apical tooth angularly bent; hind legs broken.

Metasoma. Petiole long and narrowing basally, apical width 2 times basal width and length of first tergite 1.65 times its apical width; mid-longitudinal carina present on first and second terga; first tergite sculpturing rugosecostate; second tergite granulate, faintly rugose-striate medially, small smooth basal triangular area present; third tergite granulate; remaining tergites largely smooth; length of second tergite 1.3 times median length of third tergite; ovipositor sheaths 0.09 times length of fore wing, acute apically with relatively long and thin projections; dorsal carina of petiole forming a barely semicircular area basally; base of petiole with very narrow lateral flanges.

Color. Mostly honey yellow; antenna brown (tip broken); stemmaticum and mid lobe of mesoscutum brown; metasomal terga 2 and 3 brown basally and light yellowish apically; wings hyaline, veins brown, stigma and vein C+SC+R dark brown.

Male. Unknown

Distribution. Known only from type locality in Amazonas State, Brazil.

Type material. Type-locality: BRAZIL, Amazonas State, 60 km N Manaus, Fazenda Esteio, ZF- 3 km 23, Reserva 1301, S 02°23’03” W 59°51’15”. Amazonian Rainforest. January 4, 1986. Malaise trap. Type-specimen: HOLOTYPE, ♀, point mounted. Top label: “ BRA – AM – Manaus / ZF3 – KM23 – Res 1301 / 4.I.1986 / Armad Malaise / Bert Klein, col. ” Bottom label: “ DCBU 22050” ( DCBU #22050)

Discussion. The most similar species with A. achterbergi sp. nov. is A. paradoxus sp. nov. Comments on the differences between these two species are found in the discussion section for A. paradoxus sp. nov. A. achterbergi sp. nov. is also similar to A. alternatus in color pattern, however, the fore wing r-m is present and propodeum is not areolate-rugose. This new species is similar to A. fuscatus in the almost square second submarginal cell of fore wing, and the ventrally incomplete occipital carina. It differs from A. fuscatus by the mostly honey brown color, largely dark brown in A. fuscatus , face shining granulate (largely transversely rugose in A. fuscatus ), frons with two parallel lateral carina, which are absent in A. fuscatus , and basal 2/3 of tergite 2 rugose-striate (granulate in A. fuscatus ).

Etymology. The species is named in honor of our colleague, braconidologist Cornelius van Achterberg, a codiscoverer of this interesting lineage of wasps.
