Etymology: The new species is named after one of the two collectors, Mr Eddy Poirier.

Diagnosis: Female of Ampulicomorpha with head subspheroidal, not pyriform ( Fig. 1), palpal formula 2/1 ( Figs 4, 5), OOL less than twice as long as OPL ( Fig. 1); metapectal-propodeal complex dull, rugose, without transverse or longitudinal keels ( Fig. 1).

Description: Female ( Figs 1–3). Probably macropterous (only tegulae and humeral plates of both forewings present; rest of forewings missing); hind wings complete ( Fig. 1). Length 4.1 mm. Brown, except antenna brown-testaceous and tibiae and tarsi testaceous. Antenna geniculate, not thickened distally, articulated to two frontal contiguous processes; antennomeres in following proportions: 27:8:11:10:10:10:9:9:9:12. Head ( Fig. 1) subspheroidal, not pyriform, dull, granulate, unsetose; occipital carina complete; genal carina absent; POL=4, OL=5, OOL=8, OPL=5, TL=9; greatest breadth of lateral ocellus shorter than POL (2:4); frontal line absent; face with two conical contiguous processes, on which antennae

are articulated; frons with complete narrow median longitudinal furrow from anterior ocellus to area between antennal toruli (where there is a keel in the place of a furrow); frontal area between clypeus and conical processes with two almost parallel furrows directed from upper margin of clypeus to conical processes; clypeus with margins rounded; subocular sulcus absent; eye large; head about twice as long as eye (26:13). Palpal formula 2/1 ( Figs 4, 5). Pronotum dull, granulate, covered with fine short setae, not crossed by strong transverse impression. Posterior half of pronotum with strong median incomplete longitudinal furrow ( Fig. 1). Pronotal tubercles reaching tegulae. Pronotum shorter than mesoscutum (13:23). Mesoscutum and mesoscutellum dull, granulate, covered with fine short setae. Notauli absent. Metanotum short, rugose, transverse. Metapectal-propodeal complex dull, rugose, without transverse or longitudinal keels. Mesopleuron and metapleuron dull, granulate.
