description: Key for Epsilogaster species (modified from Pitz 2004)
1 Head and mesosoma black to dark brown...................................................................2
- Head and mesosoma fulvous (Figs 1, 3), sometimes shaded with brownish infuscation...............................5
2 Transverse carinae of propodeum not complete, median areola with transverse carinae across it, but not contiguous, with transverse carinae outside areola; antenna with 23 flagellomeres; first metasomal tergite 1.5 × as long as maximum anterior width, with medial portions flattened or barely raised....................................... E. bicolor Whitifield & Mason
- At least one transverse carina of propodeum complete through median areola; first metasomal tergite about 2.0 × as long as maximum width, if shorter, then second metasomal tergum with well defined E-shaped structure; medial portion variable; antenna with variable number of flagellomeres..............................................................3
3 First metasomal tergite with medial portion raised in lateral view; antenna with 22 flagellomeres; propodeum with one clearly defined transverse carina....................................................... E. palenque Whitfield & Mason
- First metasomal tergite not raised medially in lateral view, number of antennal flagellomeres variable; propodeum with more than one clearly defined transverse carinae................................................................. 4
4 Metapleuron usually without rugulose sculpturing over most of its length; if rugulose sculpturing present, then only over distal third; mesopleuron smooth except sternaulus multifoveate and subalar depression with scattered striate sculpturing; antenna with 22 to 24 flagellomeres; propodeum with few transversal carinae............... E. williami Figueroa, López & Valerio
- Metapleuron with prominent carinae and spaced rugulose sculpturing over most of its surface; mesopleuron essentially nitid
except for sternaulus with large scrobiculate sculpturing that reaches and fuses with scrobiculate sculpturing from posterior and dorsal margins of mesopleuron; antenna with more than 24 flagellomeres; propodeum with transverse carina throughout............................................................................ E. antoniae Valerio & Whitfield 5 Longitudinal carinae of first metasomal tergite at least strong to midlength of tergum; sometimes very near lateral edge of terg- ite posteriorly (Fig. 4)................................................................................. 6
- Longitudinal carinae of first metasomal tergite weak or so laterally placed as to be difficult to discern (Fig. 3)........... 9
6 Middle arm of E-shaped sclerotization of second metasomal tergite ending abruptly at or before midlength of tergite......7
- Middle arm of E-shaped sclerotization of second metasomal tergite ending posterior to midlength of tergite..............8
7 Surface of posterior half of first metasomal tergite smooth; ovipositor sheaths strongly darkened.................................................................................................... E. dureno Whitfield and Mason
- Surface of most of first metasomal tergite coarsely sculptured; ovipositor sheaths weakly darkened or yellowish......................................................................................... E. tico Whitfield and Mason
8 Ovipositor about as long as hind tibia; lateral carinae of first metasomal tergite extending from anterior edge to about three fourths its length......................................................................... E. fullertoni Pitz
- Ovipositor 1.5 × length of hind tibia; lateral carinae extending at most to midlength of first metasomal tergite (Fig. 4)............................................................................................ E. whitfieldi sp. n.
9 First metasomal tergite about 1.5 × as long as maximal width...................... E. braziliensis Whitfield and Mason
- First metasomal tergite more than 2.0 × as long as maximal width..............................................10
10 Wings infuscate (Fig. 1)............................................................................... 11
- Wings hyaline............................................................... E.panama Whitfield and Mason
11 Propodeum with a series of transverse carinae, some of which pass through elongate areola. E. faviolae Valerio & Whitfield
- Propodeum with a tranverse carina on apical third that do not pass through areola (Fig. 3)................ E. masoni sp. n.
