Diagnosis:

Head red; mesosoma mostly black; wing with dark spot under stigma. Pronotum with one anteriorly projecting tooth. Head shining with few small punctures on frons. Hind coxa punctate.

Female:

Length, 8.0 mm; ovipositor length, 6.0 mm; forewing length 6.0 mm. Color: Antenna black, scape cark reddish. Head red with apex of mandible and palpi black. Mesosoma black with pronotum mostly reddish except anterior portion at center and upper surface of propleuron reddish. Metasoma black with venter of first segment reddish brown; ovipositor sheath black with central white band. Legs reddish brown with coxae, trochanters, extreme bases of femora, and hind tibia and hind tarsus black. Wings hyaline, extreme apex of forewing with black spot and with small, faint infuscate spot below stigma ( Fig. 56 View Figs 53-58 ); veins and stigma black. Head: Antennal length about 2.7X head width. Eyes in front view subparallel, lower interocular distance about 0.3X eye height; malar space a little less than 0.3X eye height ( Fig. 53 View Figs 53-58 ). In dorsal view, head broad and slightly narrowing behind eyes; length behind eyes about 0.7X eye length ( Fig. 55 View Figs 53-58 ). Occipital carina very narrow, less than 0.3X diameter of an ocellus. Vertex and gena glabrous, smooth, shining, without punctures; vertex without pubescence and very sparse pubescence on gena; frons shining with small punctures separated by flat interspaces one to several times diameter of punctures; pubescence dense on frons, malar area, and clypeus ( Figs 53-55 View Figs 53-58 ). Mesosoma: Propleuron shining, punctate rugose. Anterior margin of pronotum with one anteroventrally projecting tooth. Coarsely sculptured, pubescence rather sparse, densest on mesoscutal lateral lobes, scutellum, and mesepisternum. Mesonotum with short, acute, outwardly protruding anterolateral projections; mesoscutal middle lobe aerolate, with 3 or 4 irregular transverse carinae forming 4 large punctures at each side lobe; axillula more finely reticulate punctate. Pronotum with oblique scrobiculate area, anteroventrally finely reticulate punctate, dorsoposteriorly coarsely reticulate; mesepisternum finely reticulate punctate; mesepimeron scrobiculate; metapleuron and propodeum coarsely reticulate; propodeum dorsally with large punctures than laterally ( Figs 57, 58 View Figs 53-58 ). Upper surface of hind coxa densely punctate, with transverse carinae on apical half; about 1.7X longer than broad; inner surface with ovipositor guide near apex. Hind basitarsus slightly longer than length of remaining tarsal segments combined. Tarsal claws with 3 teeth and small basal lobe. Forewing with cells 1M and 1Rs separated by long vein Rs+M ( Fig. 56 View Figs 53-58 ). Hind wing veins absent (as in Fig. 157 View Figs 152-157 ). Metasoma: Shining, impunctate; pubescence densest on distal halves of segments 4 to apex. Ovipositor length about equal to forewing length.

Male: Unknown.

Types: The holotype female ( ZMUC) is labeled “ Brasilien (Amazonenstrom)” “Coary Amazonas” [handwritten, uncertain of spelling], “[?] Schletterer [?]” [handwritten, first and third words illegible], “ Coll. Wustnel. ” “ Aulacus maculatus Schletterer ,” “Type” [red], “Zool. Museum DK Copenhagen.”

Hosts: Specimens from Costa Rica were collected on a fallen branch of Pentaclethra macroloba (Willd.) Kuntze ( Fabaceae ). A specimen from Panama is labeled “ex Trachysomus thomsoni ,” which probably refers to Trachysomus thomsoni Aurivillius ( Cerambycidae ).

Remarks:

This is a widespread species occurring from Brazil and Peru north to Nicaragua.
