Diagnosis. E. incompletus sp. n. may be easily identified from the other species of the genus by the combination of the following characters: 1) mesoscutum with three longitudinal dark stripes (on lateral and central lobes) ( Fig. 16 ), 2) clypeus with a medial tooth on apical edge ( Fig. 6 ), and 3) propodeum with highly reduced carination ( Fig. 10 ).

Description. Female. Fore wing length about 9 mm. Face about 2.4 times as wide as high. Malar space about 0.7 times as high as basal width of mandible. Clypeus with a low, rounded medial tooth ( Fig. 6 ). Ocellar-ocular distance about 2.7 times as long as maximum diameter of posterior ocellus. Antenna with 28 flagellomeres.

Mesoscutum subpolished and finely punctate, punctures in middle of lateral lobe separated by about their own diameter ( Fig. 16 ). Scutellum with lateral carinae at base only. Mesopleuron dorsally polished, ventrally punctate, punctures separated by about 2 times their own diameter. Metapleuron punctate, juxtacoxal carina complete ( Fig. 14 ). Propodeum with highly reduced carination, posterior transverse carina present, medial and lateral longitudinal carinae present at extreme anterior and posteriorly only (absent medially), anterior transverse carina completely absent, surface subpolished and weakly, transversely rugose ( Fig. 10 ).

Tergite 1 about 2.8 times as long as posteriorly wide. Tergite 2 without oblique grooves. Ovipositor straight in basal third, strongly upcurved medially, then straight apically, about 1 times as long as length of hind tibia.

Yellow with dark brown-black mandibular teeth, markings on occipital area, tips of antennae (first 15 flagellomeres yellowish), edges of pronotum, anterior and posterior edges of mesopleurum, posterior part of mesopleuron, mesosternum, lateral and central lobes of mesoscutum (three longitudinal dark stripes), most carinae of propodeum, hind coxae, tergites 1–4, laterotergites, sternites, ovipositor sheaths and ovipositor (ovipositor lighter apically). Wings slightly yellowish; fore wing with a very faint darker area apically; pterostigma dark brown ( Fig. 2 ).

Male. Unknown.

Distribution. Guatemala.

Material examined. Holotype: ♀: GUATEMALA: Suchitepéq, 4 km S Vol. Atitlán, 1580 ± 7m, 14.54804 °N, 91.19108 °W, cloud forest, 15–18 Jun 2009, Malaise, LLAMA #Ma-B- 09-1-01 (Longino et al. leg.) ( ZMUT).Condition of type: intact except for missing right middle leg beyond trochanter.

Etymology. The specific name refers to the strongly reduced (incomplete) carination of the propodeum.
