description: Oneilliella Wilson 1975
Diagnosis
Antennae 8-segmented; segments III and IV each with long forked sense cones, IV with long lateral additional sense cone. Head completely reticulate, constricted behind compound eyes and basally; reticles on posterior area with a few internal dots; margins of reticles posterior to compound eyes more sclerotized, sometimes folding and forming a dark transverse line; three pairs of ocellar setae, pair III on lateral margins of the ocellar triangle, ocelli on a small elevation; compound eye with conspicuous interommatidial setae, three pairs of well-developed postocular setae; mouth cone broadly rounded; maxillary palps 2-segmented, spinasternum rectangular. Pronotum, mesonotum and metanotum reticulate; pronotal discal setae well developed; metanotum with one pair of well-developed lateral setae far from anterior margin and one pair of campaniform sensilla medially; meso- and metafurca without spinula; metafurca robust, advancing towards mesosternum. Fore wing first vein with long gap of setal row medially, 2 to 4 distal setae; second vein with about 8 setae usually regularly spaced; posterior fringe cilia wavy. Tarsi 1- segmented. Abdominal tergites I–II reticulate; tergite II long, not constricted, less than 4 times wider than long, without specialized microtrichia laterally; tergites II–VII S1 and S2 setae minute, S3 and S4 setae longer, one pair of campaniform sensilla between S1 and S2 setae; tergites III–VIII laterally with ill- or well-defined reticles associated with longitudinal lines, medially with at least ill-defined reticles anteriorly, transverse antecostal ridge present; posteromarginal craspedum present; tergite VIII with lateral teeth arising from posterior margin of craspedum; tergite IX longer than wide with five pairs of submarginal setae, S1, S3 and S5 setae longer than S2 and S4; tergite X never with a complete longitudinal split, one pair of campaniform sensilla present medially. Sternites with three pairs of setae, S1 and S2 setae close to or on posterior margin, S3 setae ahead of margin. Male with pore plates variably on sternites; three pairs of robust setae on tergite IX (Fig. 37).
Key to Neotropical Oneilliella species
1. Reticles on pronotum and metanotum with internal markings (Fig. 19).................................... tica sp. n.
-. Reticles on pronotum and metanotum without internal markings (Figs. 3, 28, 35)................................... 2
2. Antennal segment V with apex brown; tergite X with incomplete longitudinal split (cf. Fig. 23)......... funebris comb. n.
-. Antennal segment V completely pale; tergite X without longitudinal split (Fig. 36)................................. 3
3. Antennal segment III with short apical neck (about as long as wide) (Fig. 26); setae on fore wing first vein slender (Fig. 27)........................................................................................ wanessae sp. n.
-. Antennal segment III with long apical neck (twice longer than wide) (Fig. 2); setae on fore wing first vein stout (Fig. 34)... 4
4. Base of antennal segment III brown; forked sense cone on antennal segment IV not surpassing segment V (Fig. 33); fore wing first vein with 3 setae distally (Fig. 34).............................................................. williamsi
-. Base of antennal segment III pale; forked sense cone on antennal segment IV reaching mid-point of segment VI (Fig. 2); fore wing first vein with 2 setae distally (Fig. 4)........................................................ chicoi sp. n.
