Antenna ( Fig. 122 View FIGURES 118 – 127 ) dark except scape longitudinally yellow with dorsal margin and ventral margin along broader basal region dark, and usually narrowly dark apically and/or basally, and sometimes with green luster on pedicel and under some angles of light on variable number of basal flagellomeres, and then often with more distinct, white-reflective setae; length of pedicel + flagellum about 1.8× head width; scape moderately compressed basally with ventral margin sinuate so as to be broadest subbasally and narrowed apically; length[width] of scape: pedicel: funiculars: clava = 67[17]: 20[10]: 13[8], 31[8], 36[9], 38[10], 30[12], 16[13], 16[14], 15[15]: 42[16].

Mesosoma ( Figs 124–126 View FIGURES 118 – 127 ) dark brown except mesoscutal lateral flanges yellowish-hyaline and propleuron usually yellow to brownish-yellow at least mediolongitudinally, and with variably distinct and extensive greenish luster, most commonly on scutellar-axillar complex ( Fig. 125 View FIGURES 118 – 127 ) but also often on mesonotum ( Fig. 124 View FIGURES 118 – 127 ) and propodeum, and under some angles of light sometimes pronotum ( Fig. 124 View FIGURES 118 – 127 ) and acropleuron ( Fig. 126 View FIGURES 118 – 127 ).

Pronotum in dorsal view ( Figs 120, 124 View FIGURES 118 – 127 ) transverse-quadrangular with dorsal surface almost bare with very sparse, inconspicuous dark setae, and flat but inclined anterolaterally on either side of deep mediolongitudinal furrow such that anterolateral corners project tubercle-like toward head. Mesoscutum ( Fig. 124 View FIGURES 118 – 127 ) flat anteriorly and with lateral lobes carinately angled only within posterior quarter or less; meshlike reticulate; with inconspicuous posteriorly directed setae of similar color as cuticle except dense lanceolate white setae forming reflective patches antero- and posteromedially, the anterior region consisting of posteromedially directed setae forming contiguous patch, and the posterior region with posteromedially directed setae extending to posterior margin. Scutellar-axillar complex ( Fig. 125 View FIGURES 118 – 127 ) 1.25× as long as basal width with hairlike setae of similar color as cuticle along lateral margins of axillae and scutellum; axillae and scutellum longitudinally reticulate-strigose, and scutellum elongate tear-drop shaped, about 3.6× as long as greatest width, with frenal area distinctly coriaceous. Tegula with dense, long dark setae along inner margin posteriorly forming conspicuous setal tuft obviously longer than apical width of tegula ( Figs 121, 124, 126 View FIGURES 118 – 127 ). Fore wing ( Fig. 125 View FIGURES 118 – 127 ) extending to or slightly over base of gaster, about 3.4× as long as greatest width, flat or slightly upcurved only near posterior margin, hyaline; submarginal vein extending about half length of wing with comparatively long, pale setae; costal cell, membrane behind submarginal vein, and apically narrowed membrane distal to submarginal vein bare except sometimes for one or more minute marginal setae apically.

Head ( Figs 128, 129 View FIGURES 128 – 136 ) dark brown with variably distinct greenish luster except scrobal depression with distinct, light-colored line extending between interantennal prominence and dorsal margin of depression near ventral margin of anterior ocellus, and sometimes with small reddish-violaceous region at dorsal limit of interantennal prominence; vertex coriaceous-alutaceous behind posterior ocellus and medially within ocellar triangle, frons smooth and shiny except for scattered setiferous pits and face finely coriaceous-alutaceous except for smoother and shinier scrobes. Head in frontal view ( Fig. 128 View FIGURES 128 – 136 ) with ventral margin of torulus distinctly above lower orbit, vtd: dtd = 28: 22; scrobal depression transversely oval, not extending to inner orbits though without distinct parascrobal regions. Head in dorsal view ( Fig. 129 View FIGURES 128 – 136 ) with interocular distance about 0.5× head width; OOL: POL: LOL: MPOD = 5: 13: 7: 9; without distinct ocellocular mark.

Distribution (Map 2A). Costa Rica, Ecuador, Peru, Venezuela.

Remarks. Ooderella spinositegula , O. thegalea and O. melanosceles comprise a species trio, as discussed under the latter species. Because of their longer fore wings, females of O. spinositegula ( Fig. 125 View FIGURES 118 – 127 ) more closely resemble those of O. melanosceles ( Fig. 52 View FIGURES 45 – 53 ) than those of O. thegalea ( Fig. 153 View FIGURES 147 – 155 ), but are distinguished by conspicuously longer tegular tufts of setae (cf. Figs 126 View FIGURES 118 – 127 , 51 View FIGURES 45 – 53 ) and the metacoxa being bare mediolongitudinally ( Fig. 126 View FIGURES 118 – 127 ) rather than the outer surface being almost entirely setose ( Fig. 51 View FIGURES 45 – 53 ). Females are also differentiated by color over some of their range, the females from Ecuador and Peru having the propleura at least partly pale as well as more extensively pale legs than for O. melanosceles . The two females from Costa Rica and Venezuela have the propleura entirely dark and mostly dark legs though both females have the mesotibia distinctly pale basally.

Males described as O. spinositegula are differentiated from those of all other species by their flagellar mps structure, consisting mostly of a long, apically free portion such that convex, longitudinal mps appear to be lacking and each mps superficially looks like a long seta projecting at an acute angle from the flagellomere ( Figs 131, 132 View FIGURES 128 – 136 ). If O. spinositegula , O. thegalea and O. melanosceles form a monophyletic group then the unknown males of the other two species likely have similar flagella with seta-like mps. The CNC has two males from Brazil and one from Bolivia not associated with females that have similar flagella to the two O. spinositegula males except the convex basal portion of the mps along the flagellomere is much longer, with the apically free, seta-like portion only about one-half or less the total length. This mps structure is thus intermediate between that of O. spinositegula ( Fig. 132 View FIGURES 128 – 136 ) and the mps structure shared by O. setosa ( Fig. 85 View FIGURES 81 – 89 : insert) and O. smithii ( Fig. 105 View FIGURES 101 – 109 ).
