Key to the species of female Hydrophylita

1 Forewing very narrow with apex distinctly pointed, its length at least 14x its width ( Fig. 3 E), disk with only a single linear track of setae. Antenna with placoid sensilla (PLS) on each club segment attached to surface almost their entire length ( Fig. 3 C) ........................................................... subgenus Hydrophylita .2

1’ Forewing wider ( Figs. 1 G, 2B, 4B), with apex slightly pointed at most, its length less than 10x its width, disk densely setose. Antenna with one or more PLS on each club segment spinelike, attached to surface only at the base ( Fig. 1 F) ......................................................................................... subgenus Lutzimicron .3

2 Antenna with one anellus. U.S.A. and Canada....................................................................... H . aquivolans

2’ Antenna with two anelli ( Fig. 3 B). Central and South America.............................................. H . bachmanni

3 Antenna with funicular segments subequal in length ( Figs. 4 C, D), first club segment (C1) subequal in length to first funicular segment (F1), club poorly differentiated from funicle. Forewing c. 8x as long as wide. ( Figs. 4 A, B). SE Brasil........................................................................................................ H . lestesi

3’ Antenna ( Fig. 1 A) with F2 and C1 both distinctly shorter than F1, club well differentiated from funicle. Forewing ( Figs. 1 G, 2B) c. 6x as long as wide............................................................................................ 4

4 Antennal segments moderately long, first and second club segments (C1, C2) less than 3x as long as wide, third club segment (C3) no more than 3x as long as wide Figs. (1A–F). Ovipositor moderately long ( Figs. 1 I, 5A) less than 2.5x hindtibial length. Broadly distributed in Neotropics ........................ H . neusae n. sp.

4’ Antennal segments more elongate, C1 and C2 more than 3x as long as wide, C3 more than 4x as long as wide. Ovipositor considerably longer ( Fig. 5 B), length at least 2.5x hindtibial length. Bolivia................... ......................................................................................................................................... Hydrophylita sp. A
