Type material. Holotype ♀ ( MZUCR). “ COSTA RICA , Puntarenas | San Vito, Estac. Biol. Las | Alturas , 1500m, V.1992 | Hanson & Godoy / HOLOTYPE | Ooderella | hyalipleura | Gibson” . Holotype card-mounted by right side; entire; contorted.

Paratype. Costa Rica. Guanac Est. Pitilla, 9 km S Santa Cecilia , 700m, IX.1988, P. Hanson (1♀ CNC, Photo 2016-82).

Etymology. A combination of the Greek words hyalion (mirror) and pleura (side), in reference to the smooth and shiny acropleuron of females, one of the differentiating features of the species.

Description. FEMALE (habitus: Fig. 38 ). Length about 3.4–[3.9] mm (approximate because both females contorted). Head ( Figs 35–38 ) with lower face green to bluish but upper face darker with variably distinct greenish to reddish-violaceous lusters under some angles of light, and scrobal depression with reddish-violaceous luster ( Fig. 35 ); in lateral view ( Fig. 36 ) moderately convex with frontal surface almost uniformly curved but frontovertex longer than lower face such that broadest slightly below middle, almost 1.6× as high as long; in frontal view ( Fig. 35 ) about 1.2× as wide as high; in dorsal view ( Fig. 37 ) almost 1.6× as wide as long with interocular distance almost 4× head width, with at most a short transverse ridge slightly developed at anterior margin of posterior ocellus but without distinct ocellocular mark, and with OOL: POL: LOL: MPOD = 15: 25: 16: 11. Frontovertex with vertex reticulate posteriorly and anteromedially to at least between posterior ocelli ( Fig. 37 ) and sometimes within ocellar triangle, but smooth posterolateral of ocelli and frons smooth and shiny except for setiferous pits and narrow, longitudinal band of slightly reticulate sculpture below anterior ocellus to scrobal depression ( Fig. 35 ), and with whitish hairlike setae. Scrobal depression ( Fig. 35 ) transversely Π-shaped immediately above interantennal prominence, consisting of meshlike coriaceous-imbricate scrobes above toruli, moderately distinct transverse furrow or angulation between scrobes and interantennal region ventrally, and short, transversely reticulate region dorsal to angulation; interantennal prominence uniformly convex with subparallel sides so as to be broad dorsally between scrobes ( Fig. 35 ). Interantennal prominence, lower face and parascrobal region to dorsal limit of scrobes with white lanceolate setae. Mandible ( Fig. 35 ) bidentate with acute ventroapical tooth and broad, slightly incurved dorsoapical margin. Labial and maxillary palps brown. Antenna ( Fig. 39 ) dark with variably distinct green luster on scape and at least some flagellomeres, the greenish flagellomeres with more distinct white setae (cf. Fig. 66 ); length of flagellum + pedicel about 2.1× head width; scape slightly compressed and curved, similarly slender throughout; length[width] of scape: pedicel: funiculars: clava = 91[15]: 27[12]: 19[10], 52[12], 53[12], 58[17], 41[20], 34[20], 23[20], 21[20]: 49[22].

Mesosoma ( Figs 40, 41 ) dark brown except mesoscutal flange yellowish-translucent and outer inclined surface of lateral lobe somewhat lighter brown. Legs similar in color to mesosoma except metacoxa white apically, and metatrochanter and knees sometimes slightly paler, and tarsi sometimes more obviously paler, brownish-yellow. Pronotum in dorsal view ( Fig. 37 ) with collar transverse-quadrangular, about 2× as wide as long with anterolateral corners right-angled relative to comparatively poorly differentiated anterior margin, the dorsal surface flat with anterior margin obtusely angled relative to neck on either side of deep mediolongitudinal furrow, and with sparse, inconspicuous pale setae. Mesoscutum ( Fig. 40 ) flat anteriorly and with lateral lobes carinately angled only within about posterior quarter; meshlike reticulate; with inconspicuous posteriorly directed setae of similar color as cuticle except posteromedially with ovate region of dense white lanceolate setae extending to posterior margin, with most of setae directed medially but with anterior-most setae directed more anteriorly and posterior-most setae directed more posteriorly. Scutellar-axillar complex ( Fig. 40 ) with ratios not accurately measureable but at least sculpture and setal patterns similar to that of O. hansoni . Tegula ( Fig. 41 ) uniformly covered with dark setae except bare posterolaterally. Fore wing ( Figs 40, 42 ) flat, about 2.6× as long as greatest width, but extent extending posteriorly not evident because both specimens contorted (likely extending only slightly over base of propodeum), and brownish-infuscate basally but hyaline apically; neither costal cell nor submarginal vein extending quite to angulate apical wing margin, with costal cell setose ventrally and submarginal vein with much longer, dark setae compared to very sparsely setose membrane behind vein, including more numerous marginal setae within apical half. Mesopleurosternum ( Fig. 41 ) with region of dense white lanceolate setae forming setal tuft anteriorly on acropleuron and mesopectus dorsally, and mesopectus ventral to setal tuft with somewhat more sparsely setose region of ventrally projecting white lanceolate setae, the more dorsal setae less conspicuous, hairlike, and extending anterior of acropleural setal tuft to anterior margin of mesopectus; acropleuron smooth and shiny except finely coriaceous along dorsal and posterior margins. Metacoxa densely setose with white lanceolate setae dorsally and ventrolaterally, and with a few white setae medially on outer surface, but bare on outer surface basally and apically. Propodeum ( Fig. 40 ) comparatively long with posterior margin deeply incurved at midline such that recurved margins united into high median carina, reticulate-rugulose, and with a couple of white lanceolate setae anterolaterally anterior to spiracle and longer hairlike white setae posterolaterally.

Gaster ( Figs 38, 43 ) dorsally white subbasally ( Figs 38, 41, 43 ) and ventrobasally ( Fig. 41 ), otherwise dark brown with variably distinct greenish to reddish-violaceous lusters under some angles of light except syntergal flange brownish- to yellowish-translucent, and ovipositor sheaths brown basally to yellowish apically; shiny with only very fine, subeffaced coriaceous sculpture and beyond Gt2 with long, sparse setae of similar color as cuticle in single row across tergites; syntergum ( Fig. 44 ) short, only about as long as basal width and much shorter than penultimate tergite, with dorsal surface in similar plane such than syntergal flange differentiated as lighter-colored, more translucent, posteriorly angulate, bare region behind subapical row of dark setae; ovipositor sheaths extending conspicuously beyond syntergal flange, by distance about equal to 0.5× length of metatibia.

Distribution (Map 1D). Costa Rica.

Remarks. Females of O. hyalipleura are most similar to those of O. reticulifrons and O. hansoni , as discussed under the latter species. Because both females of O. hyalipleura are contorted it is not possible to accurately describe some structures, including the length that the fore wings extend or the structure of the propodeum anteriorly, though the former likely is similar to that described for O. hansoni and the anterior margin of the propodeum likely is at least slightly incurved at the midline. Females are distinguished by their unique head sculpture pattern ( Fig. 35 ), in which the frons is mostly smooth and shiny except for setiferous pits but reticulate medially in a band below the anterior ocellus, and sometimes also within the ocellar triangle.
