Diagnosis.
This species can be distinguished from all other
Hymenoepimecis
by the combination of the following characters: 1) fore wing hyaline yellowish, with two blackish bands; 2) pronotum orange; 3) female with tarsal claw with more or less square lobe, and with apex overtaking the lobe; 4) female with ovipositor 1.2 times as long as hind tibia.

Description.
Female.
Body [9.0] mm; face [1.0] times as broad as high, smooth, slightly convex with few spaced bristles; head in dorsal view, with gena strongly narrowed behind eyes; posterior ocelli separated from eyes by approx. [1.0] times its own maximum diameter; occipital carina projected and weakly reduced and curved upwards dorsally. Pronotum long, smooth and polished, with distance from tegula to head approx. [0.8] times distance from tegula to hind margin of propodeum, and in anterior part with opening pocket-like structure not reduced longitudinally; mesoscutum smooth and polished; scutellum, in profile, convex; mesopleuron smooth and polished, with anterodorsal and posterodorsal parts bearing sparse, fine setiferous punctures; metapleuron smooth and polished, rather uniformly covered with sparse, fine setiferous punctures; propodeum smooth, polished, with sparse, fine setiferous punctures and with lateral longitudinal carina present only posteriorly. Fore wing [7.0] mm; cu-a more or less interstitial to the base of Rs&M; 2rs-m [0.5] times as long as abscissa of M between 2rs-m and 2m-cu; hind wing with abscissa of Cu1 meeting cu-a equidistant between M and 1A. Hind leg with tibia + tarsus [0.6] times the fore wing length; tarsal claw with more or less square lobe, with apex of claw overtaking the lobe. Metasoma slender; tergite I [1.4] times as long as posteriorly width, centrally quite strongly convex with lateral carinae present only at extreme anterior end flanking the anterior concavity; sternite I with a low, rounded swelling posteriorly; tergite II approx. [1.2] times as long as posteriorly width; tergites III and IV approx. [1.1] times as long as posteriorly width; ovipositor [1.2] times as long as hind tibia.
Colour.
Head black; clypeus black with apex yellowish; mouthparts yellowish, with apex mandible black; antenna brownish. Mesosoma orange. Fore and mid leg orange, the hind entirely blackish brown. Fore wing hyaline yellowish, with apex blackish and with a blackish preapical band; pterostigma with basal half black and apical half yellow; hind wing with slightly blackish band in median part. Metasoma orange, with tergites VI+ black; ovipositor and sheath brownish.

Comments.
Hymenoepimecis ecuatoriana
sp. nov. closely resembles
H. neotropica
(Brues & Richardson, 1913),
Hymenoepimecis longilobus
sp. nov. and
H. duckensis
Padua
& Onody, 2015 mainly by having the fore wing yellowish hyaline with two blackish bands, metasoma orange with last tergites black and face without a sculptured, longitudinal carina in the middle part of face. It differs from the first and second congeneric species by having tarsal claw with a more or less square lobe (tarsal claw with a preapical tooth, in
H. neotropica
and lobe longitudinally elongated in
H. longilobus
sp. nov.), and from the last species by having the ovipositor <1.3 times as long as hind tibia (> 1.5 times as long as hind tibia in
H. duckensis
).
