Key to the species of Evertomyia

1. Face with paired black spots on ventral portion (e.g., Figs. 3 A, C–E). Frons with fronto­orbital plates silvery grey pruinose ( Figs. 3 A, E), at least in part ( Figs. 3 C– D). Scutum with dorsocentral vittae or with entire dorsal part silvery grey.............. 3

– Face without darkened spots ( Figs. 3 B, F). Fronto­orbital plates easily differentiated from remainder of frons, but not silvery grey ( Figs. 3 B, F). Scutum neither vittate nor dorsally silvery grey ........................................................................................... 2

2 (1). Anterior orbital seta smaller than outer vertical seta, located near middle of frons length; fronto­orbital plates light bronzy brown pruinose ( Fig. 3 B). Face yellowish, facial carina distinctly keeled. Antennal 1st flagellomere and maxillary palpus orange. Scutum, scutellum, and pleural area unicolorous light bronzy brown pruinose

..................................................................................................... frankadelia , sp. nov. – Anterior orbital seta larger than outer vertical seta, located in anterior part of frons; fronto­orbital plates shiny orange, lacking pruinescence ( Fig. 3 F). Face covered with silvery grey pruinescence, facial carina not keeled. Antennal 1st flagellomere and maxillary palpus dark brown. Scutum and scutellum light brownish orange; pleural area lighter colored, nearly yellow ..................................................... webbi , sp. nov.

3 (1). Frons with fronto­orbital plates silvery grey pruinose only anteriorly, forward of anterior orbital seta ( Fig. 3 C); remainder light bronzy pruinose. Scutum with light bronzy dorsocentral vittae ( Fig. 2 ). Distinct dark stripe from proepisternum through posterior katepisternal seta ............................................................... helenae , sp. nov.

– Frons with fronto­orbital plates entirely silvery grey pruinose ( Figs. 3 A, D–E). Scutum with silvery grey dorsocentral vittae or with entire dorsal part silvery grey. Proepisternum through katepisternum variously marked, but never with entire stripe ................................................................................................................................... 4

4 (3). Scutellum and dorsal part of scutum entirely silvery grey pruinose, not vittate. Anepisternum silvery grey, with distinct darkened spot at base of anepisternal seta ........ ............................................................................................................ matilei , sp. nov.

– Scutum brownish­orange, with distinct, thin silvery grey dorsocentral vittae that extend through scutellum. Anepisternum with coloration variable, but lacking distinct spot at base of anepisternal seta ....................................................................... 5

5 (4). Ptilinial suture with borders distinctly darkened, fading below level of facial spots ( Fig. 3 A); antennal groove at most slightly darkened, never concolorous with paired facial spots. Face with slightly to distinctly darkened median facial spot above paired facial spots and below facial carina ( Fig. 3 A). Midtibia with 2 strong spurs. Silvery grey vittae on scutellum extend around posterior edge, visible from dorsal view ............................................................................................................. albeto , sp. nov.

– Ptilinial suture with border darkened only in dorsal part, fading out above level of facial spots; antennal groove distinctly darkened as medial triangular extension from dorsal part of ptilinial suture, concolorous with facial spots ( Fig. 3 D). Face lacking median spot. Midtibia with 1 strong spur. Silvery grey vittae on scutellum not extended around posterior edge, although posterior edge pale yellow from posterior view....................................................................................................... irwini , sp. nov.
