Holotype. ♁, “ EcUADOR:\ 3 mi. W. of Paute , Azuay \ 17-II-1965 ” “ E.I. Schlinger \ & E.S. Ross \ collectors ” ( SEMC).

Paratypes. 3♁♁, 1♀, with same label data as that of holotype; 2♁♁, 1♀ ( SEMC) and 1♁, 1♀ ( MZSP) labeled, “ EcUADOR, Cuenca \ Azuay Prov. \ III-13-1965 ” “ L.E. Pena \ collector” .

Diagnosis. Both sexes with preoccipital ridge carinate; female metabasitibial plate well rimmed; female metapostnotum with striations weakly reaching posterior margin where they become difficult to discern among strongly granular integument (Fig. 3); male face almost straight above antennal alveoli, setae on this portion long and weakly branched; apical margin of metasomal sternum III not notched; apical margin of metasomal sternum IV straight, subapical margin with a distinct median patch of erect setae, length of lateral projections less than sternum length (Fig. 7).

Description. Female: Total body length 7.0 mm; forewing length 5.2 mm; distance between compound eye notches 1.3 mm; maximum head length 1.7 mm; intertegular distance 1.33 mm. Head slightly triangular (Fig. 1); mandible with weak subapical tooth; malar space very short, less than basal mandibular width; compound eyes with minute setae; preoccipital ridge carinate. Mesoscutum anterior border slightly acuminate. Inner metatibial spur pectinate, with four branches excluding apical portion of rachis. Forewing with 1m-cu confluent with 1rs-m; maximal length of third submarginal cell more than twice maximal length of second submarginal cell. Metapostnotum as long as mesoscutellum, broadly rounded posteriorly. Metasoma broadly rounded; terga not depressed; sterna unmodified.

Head punctate, punctures contiguous on upper parocular area, those punctures on frons stronger than elsewhere on face. Mesoscutum densely punctate, punctures irregular in diameter, contiguous around parapsidal lines and posteriorly, separated by less than a puncture width centrally, blending to strongly imbricate integument medioanteriorly. Mesepisternum densely punctate and rugulose. Metapostnotal striations longitudinal and partly irregular, striations covering entire surface, apically weaker and difficult to discern among strongly granular integument (Fig. 3). Metasomal terga lineolate with small puncures, those of tergum I smaller in diameter than those on other terga.

Integument of head and mesosoma brilliant metallic green with some cupreous reflections. Mandible, labrum, malar space, and apical one-half of clypeus dark brown; antenna, all leg podites, tegula, and sterna light brown. Wing veins brown; membrane lightly fuscous. Terga mostly brilliant metallic green with small brown areas on median surface of metasomal terga I and II, apical marginal areas translucent brown, abruptly demarcated from remainder of terga.

Pubescence on head, mesosoma, and sterna pale yellow, on legs dark amber, on terga light amber. Setae short on terga, long and erect on sterna; metasomal sternum II and III with long setae with recurved apices.

Male: as described for female except as follows: Total body length 6.0 mm; forewing length 4.8 mm; distance between compound eye notches 1.2 mm; maximum head length 1.8 mm; intertegular distance 1.1 mm. Head longer than wide; not strongly depressed (Fig. 5). Mesoscutal median line well impressed. Metapostnotum as long as mesoscutellum, slightly depressed. Lateral projection of metasomal sternum IV as long as sternum length (Fig. 7); metasomal sternum VI strongly emarginate; metasomal sternum VII and VIII as depicted in Figure 9; genital capsule as depicted in Figure 11.

Clypeus and supraclypeal area with fewer punctures than lower parocular area, with imbricate microreticulations. Mesoscutum strongly punctate, punctures separated by less than a puncture width, integument between (where perceptible) with imbricate microreticulations. Metapostnotal striae dense, almost entirely longitudinal, extending along entire surface, weaker apically and difficult to discern among strongly granular integument. Terga irregularly punctuate and lineolate.

Integument of head and mesosoma brilliant metallic green with some dark reflections. Apical margin of clypeus narrowly pale amber. Coxae to femora with metallic highlights, tibiae and remaining podites dark amber. Metasoma entirely brown.

Pubescence on face long and plumose, especially above supraclypeal area. Lateral projection of metasomal sternum IV bearing four setae at apex, sternal apical margin with a central patch of setae (Fig. 7). Genital capsule as depicted in Figure 11.

Etymology. The specific epithet is a patronym honoring Mr. Daniel J. Bennett, leading student of the systematics of crabronine wasps.
