Key to Brachymeria spp. of the subrugosa complex based on females

1 Basal fold of fore wing densely setose with over 20 setae, sometimes partly arranged in several rows ( Figs 9 F, 10D).......2

1' Basal fold of fore wing less densely setose with at most 15 setae arranged in one row................................3

2(1) Upper edge of antennal scrobes not quite reaching lower margin of median ocellus ( Fig. 9 A). Basal fold of fore wing with about 30 setae partly arranged in several rows ( Fig. 9 F). Ocellar ocular distance hardly shorter than lateral ocellus diameter ( Fig. 9 A)........................................................................... B. subconica Bouček

2' Upper edge of antennal scrobes reaching median ocellus. Basal fold of fore wing with about 20 setae arranged in one row ( Fig. 10 D). Ocellar ocular distance much shorter than lateral ocellus diameter.................. Brachymeria sp. [= ' Brassolis ']

3(1') Adtorular carina vestigial, i.e. thin, incomplete, hardly raised and hence visible in some angles only ( Fig. 6 C). Clypeus dorsally with 7−9 large piliferous punctures, mostly arranged in one row, apart from the smaller ones below. Gena, lower face and supracoxal stripe of metepimeron densely setose ( Fig. 6 A, B, H). Clava subovoid and bearing a large area of micropilosity ( Fig. 6 F, G). Basal fold of fore wing with 10−15 setae (median 13). Mandible almost entirely black ( Fig. 6 B). Mesotibia with incomplete black ring ( Fig. 6 K). Upper half of epicnemium black ( Fig. 6 I)................ B. philornisae Delvare sp. nov.

3' Adtorular carina more distinctly expanded and visible ( Fig. 6 B). Clypeus with different ornamentation—either the large points are irregularly distributed ( Fig. 8 C) or less numerous ( Fig. 7 B). Gena, lower face ( Fig. 7 A, B) and supracoxal stripe of metepimeron moderately setose ( Fig. 7 D). Clava tapering and with small area of micropilosity ( Fig. 7 C). Basal fold of fore wing sometimes with less than 10 setae. Mandible, except teeth, largely brown in apical half ( Fig. 7 B). Mesotibia with complete black ring. Upper half of epicnemium sometimes orange ( Fig. 7 F)..........................................4

4(3') Adtorular carinae thin, visible as irregular rugae ( Fig. 8 C). Antennal scrobes virtually as high as eye (0.97×), hence upper edge of scrobes about at level of upper ocular line ( Fig. 8 A). Clypeus with irregularly distributed points ( Fig. 8 C). Upper half of epicnemium black................................................................... B. subrugosa Blanchard

4' Adtorular carinae thick, appearing as a swelling ( Fig. 7 B). Antennal scrobes 0.88−0.91× as high as eye, hence upper edge of scrobes slightly but distinctly below upper ocular line. Clypeus with 3 large points on either side in a dorsal row ( Fig. 7 B). Upper half of epicnemium orange ( Fig. 7 F)........................................ B. costalimai Delvare nom. nov.
