Key to species of Neopomphale

1 Gastral membranes red to yellowish red........... 2

– Gastral membranes yellowish to white, or pale brown........ 3

2(1) Face and frons partially (male) to almost entirely (female) white; male flagellum (figure 36) stout (first claval segment 2.1× as long as wide), with short setae (setae on first claval segment 1.3× as long as segment).... rubescens sp. n. X, W

– Face and frons dark; male flagellum (figure 48) narrow (first claval segment 3.6× as long as wide), with long setae (setae on first claval segment 2.2× as long as segment)............... azofeifai sp. n. W

3(1) Wing fringe on fore wing long, about as long as submarginal vein (figure 65).................... longipilis sp. n. X, W

– Wing fringe on fore wing shorter, usually at most 0.7× as long as submarginal vein (figures 60–63, 64)................ 4

4(3) Mesoscutum and frons predominantly or completely pale yellow...................... aleurothrixi (Dozier) X, W

– Mesoscutum and frons predominantly dark brown to black...... 5

5(4) Longest distance from base of marginal vein to apical margin of fore wing is to anterior one-half of wing (figure 63), and speculum missing; base of fore wing not strongly infuscate............. xenipennis sp. n. X

– Longest distance from base of marginal vein to apical margin of fore wing is to median part or to posterior one-half of wing, or speculum present; base of fore wing sometimes strongly infuscate............. 6

6(5) Basal one-third of fore wing infuscate and speculum very small (as in rubescens (figure 60))................... 7

– Base of fore wing not infuscate or speculum larger (e.g. figures 4, 62, 64)... 9

7(6) Head less transverse (0.9× as high as wide)..... graciliclava sp. n. X

– Head transverse (0.7× as high as wide)............ 8

8(7) Setae on flagellomeres ± erect (figure 50) and at least twice as long as segment attached to............... erecta sp. n. W

– Setae on flagellomeres not erect (figure 37) and shorter than twice the length of segment attached to............. cerrobius sp. n. W

9(6) Scutellar setae situated at or only slightly separated from hind margin of scutellum (figure 57)............... prymna sp. n. X

– Scutellar setae situated in the middle or slightly behind the middle of scutellum. 10

10(9) Head transverse (figure 58), 0.7× as high as wide; malar space slanting steeply inwards towards mouth opening......... transversa sp. n. X

– Head less transverse (e.g. as in figures 17, 59), at least 0.8× as high as wide; malar space slanting less steeply inwards............. 11

11(10) Female with hind femur predominantly pale (but with an apical dark spot) and hind tibia dark.............. dichrous sp. n. X

– Females not with this combination of colour on hind leg; if male continue here. 12

12(11) Male with funicular segment distinctly asymmetric (figures 41, 55).... 13

– Male funicular segment symmetric; if female continue here...... 14

13(12) Fore wing with three or four admarginal setae (i.e. setae on ventral surface of wing membrane, close to marginal vein)....... dichrous sp. n.

– Fore wing with one admarginal seta........ nonaequa sp. n.

14(12) Fore wing with a wide bare stripe below marginal vein (figure 64), ratio width of bare stripe (measured below middle of marginal vein)/length of submarginal vein=0.32................ depilis sp. n. X

– Fore wing with setae close to marginal vein, at most with a narrow bare stripe
