Oneilliella tica sp. n.

( Figs 16–23 )

Female macroptera. Body mostly brown ( Fig. 16 ), except for area between outer margins of ocellar triangle and compound eyes light brown ( Fig. 19 ), tarsi and apex of mid and hind tibiae yellow, fore femora light brown and fore tibiae light brown with apex yellow. Antennal segment I yellow with brown shadings basally, II yellow basally and apically and brown medially, III brown medially, basal half yellow and apex light brown, IV brown with basal fourth yellow and apical fourth light brown, V yellow with apical third brown, VI brown, VII–VIII light brown ( Fig. 17 ). Fore wing brown, except for sub-basal pale spot, anteriorly to fork of veins. Antennal segment III with short apical neck, about as long as wide, forked sense cone on segment IV reaching apex of segment V. Fore wing setae slender, first vein with two distal setae, second vein with 8 regularly spaced setae, fork of veins with robust microtrichia, clavus with 3 setae in addition to a marginal seta ( Fig. 18 ). Reticles on pronotum and metanotum with internal markings ( Fig. 20 ). Abdominal tergite II 3.6 times wider than long and almost entirely covered by polygonal reticulations, except medially submedially on posterior margin and laterally on anterior angles, tergites III–VIII without sculpture medially and with well-defined reticles submedially and longitudinal striae laterally ( Fig. 22 ); X with incomplete longitudinal split ( Fig. 23 ).

Male. Unknown.

Measurements (Female holotype in microns): Body length 1100. Head length 88; width 168. Pronotum length 93; width 188. Forewing length 700, setae length 23. Abdominal tergite II medial length 65, width 228. Length of antennal segments I–VIII 25, 38, 50, 50, 35, 28, 15, 28 apical neck on segment III length 13, width 7.

Material studied. Holotype female. Costa Rica. La Selva , Pentaclethra canopy fogging, 5.x.1992 (L.A. Mound) ( NHM) . Paratype females. Costa Rica. La Selva , Piper sp. flowers, 27.iv.1992, 2 females; Guapiles, in dead branch, 13.ix.1991, 1 female (L.A. Mound) ( NHM) .

Comments. This species is easily recognized by the distinctive internal markings on the pronotal and metanotal reticles. The holotype has all reticles on pronotum with internal markings, while in the paratype some medial reticles lack internal markings and one of the fore wings has only six setae on second vein. Apart from that, it shares with funebris the antennal segment V with apical third brown and the well-defined reticles laterally on abdominal tergites III–VIII. It is named after its type location. The species is named after the national Costa Rican name for those born in the country (tico/tica).
