Male
. Fully winged; length 2.2–4.4 mm. Head brown, except mandible and clypeus more or less yellowish. Antenna testaceous. Mesosoma and metasoma brown. Legs yellow. Antenna not geniculated, filiform, not thickened distally, without rhinaria; antennae articulated to prominent contiguous processes; antennal toruli very far from upper margin of clypeus. Antennal segments in following proportions: 10.5:3.5:12:12:11:11:9:10:9:12. Head shiny, unsculptured, finely hairy, with dorsal side swollen; occipital carina complete; ocelli distinct; POL = 2; OL = 2; OOL = 4,5; OPL = 3; TL = 7; faces without track of median furrow from anterior ocellus to antennal toruli; eye small, approximately 0,5 as long as head; region of face from clypeus to antennal toruli with two distinct longitudinal and median sutures very convergent and much nearer antennal toruli than clypeus. Maxillary palpi with five segments; labial palpi with two segments; third segment of the maxillary palpi broadened. Pronotum dull, crossed by strong transverse impression, shorter than scutum (6:14); anterior collar short; disc rugose, short, without track of median longitudinal furrow; pronotal tubercle reaching tegula; posterior surface of pronotum shorter than scutum (2:14). Scutum dull, granulated, covered with short hairs. Notauli incomplete, hardly visible near anterior margin of scutum. Scutellum shiny, unsculptured. Metanotum very short, unsculptured, shiny. Propodeum dull, reticulate rugose, with two long and parallel longitudinal keels from distal apex to metanotum; dorsal surface without median longitudinal furrow. Fore wing hyaline, without dark transverse bands; first discal cell (1DC) and first subdiscal cell (1SDC) fully enclosed in
holotype
; 1 SDC cell not completely enclosed by pigmented veins in
paratype
; marginal cell open; stigmal vein regularly curved, with distal part longer than proximal part (15:12). Dorsal membranous process of paramere (

Distribution
.
Japan
(Hachijo, Honshu, Kyushu).
Remarks
.
Olmi (1996)
recorded erroneously
E. hachijoensis
(as
Ampulicomorpha hachijoensis
) from
Taiwan
; that record however is related to
Ampulicomorpha taiwanensis
Olmi 1998
(unpublished data).
