Tetrastichus epidius Walker 1847:28. Lectotype ♀ (primary type no. 5.141 3, NHMUK 013458201) designated by Burks (1975:142), examined. U.S.A. (Florida).

Galeopsomyia epidius (Walker), Graham & LaSalle (1991:91).
Diagnosis (female). Antenna with a weak constriction between C1 and C2 (Fig. 998); genal carina absent; eyes small 1.0× as long as malar space (Fig. 887); mesoscutellum (Figs 648, 658) with strong reticulation, meshes isodiametric in posterior half, elongate in anterior half, submedian grooves indistinct and partly absent, slightly curved and diverging towards posterior part, with a ±complete median groove; dorsellum without median carina; propodeum with strong reticulation (Figs 648, 658), callus with six setae; gaster 3.1× as long as wide, Gt 2 0.3× as long as Gt 4, tergites with strong reticulation (Figs 648, 658).
Description (female nontype). Length of body 2.6mm (specimen measured) (variation in material 2.3–3.1mm).
Scape yellowish-brown with dorsal part brown, pedicel and flagellum dark brown. Head with frons bluish-green, antennal scrobes black, clypeus dark brown. Vertex bluish-green. Thoracic dorsum golden-green. Legs with fore and mid coxae black with metallic tinges, hind coxa golden-green; trochanters dark brown; femora black with apex yellowish-brown; fore tibia brown, mid and hind tibiae with basal half brown and apical half yellowish-brown; T1–3 yellowish-brown, T4 dark brown. Petiole black. Gaster golden-green; gonoplac black.
Antenna with a weak constriction between C1 and C2. Frons with strong reticulation, clypeal area smooth, antennal scrobes with weak reticulation; without genal carina. Vertex with strong reticulation.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe without median groove, with seven scattered adnotaular setae. Mesoscutellum with strong reticulation, meshes isodiametric in posterior half, elongate in anterior half; submedian grooves indistinct and partly absent, slightly curved and diverging towards posterior part; with a ±complete median groove; frenal groove wide and subdivided by carinae; with an expanded and strongly reticulate part behind frenal groove. Dorsellum with strong reticulation. Propodeum with a strong and relatively wide median carina that expands posteriorly; callus with six setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa with a carina along posterior margin. Fore wing with five setae on dorsal surface of submarginal vein; speculum open.
Petiole very short, just a narrow band. Gaster elongate; tergites with strong reticulation.
