Metasoma. 1.7 x length of mesosoma; T1 and T2 narrow when viewed dorsally, glabrous; ovipositor 13.4 mm.
MALE. Unknown
Remarks. Aulacus enarotadi has an ovipositor guide on the hind coxae which is somewhat medial on the inner surface and angled slightly posteriorly ( Fig. 6 View FIGURES 4 – 9 ) and, in this respect, it differs from the other Aulacus species from New Guinea, although it is similar to a number of Australian species, including several as yet undescribed species from northern Queensland. In A. sedlaceki , the hind coxa has a flattened inner surface and has a slight extension on the inner disto-ventral surface, extending posteriorly for a distance about equal to one-quarter the length of the trochanter ( Fig. 9 View FIGURES 4 – 9 ). The ovipositor guide is an elongate and posteriorly-pointing depression extending to the tip of the hind coxal extension, and with a margin fringed with stout setae ( Fig. 9 View FIGURES 4 – 9 ). It also differs from A. wau in which the ovipositor guide is also a shallow depression but in this species it is almost horizontal on the lower ventro-medial inner surface of the hind coxae (Fig. 11).
The species name is named after the type locality, Wisselmeren, Enarotadi , West Papua, Indonesia ( Fig. 1 View FIGURE 1 ). Nothing is known of its host biology.
