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 9View FIGURE 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. 9View FIGURE 9 A). Basal fold of fore wing with about 30 setae partly arranged in several rows ( Fig. 9View FIGURE 9 F). Ocellar ocular distance hardly shorter than lateral ocellus diameter ( Fig. 9View FIGURE 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. 10View FIGURE 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. 6View FIGURE 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. 6View FIGURE 6 A, B, H). Clava subovoid and bearing a large area of micropilosity ( Fig. 6View FIGURE 6 F, G). Basal fold of fore wing with 10−15 setae (median 13). Mandible almost entirely black ( Fig. 6View FIGURE 6 B). Mesotibia with incomplete black ring ( Fig. 6View FIGURE 6 K). Upper half of epicnemium black ( Fig. 6View FIGURE 6 I)................ B. philornisae Delvare  sp. nov.

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

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

4' Adtorular carinae thick, appearing as a swelling ( Fig. 7View FIGURE 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. 7View FIGURE 7 B). Upper half of epicnemium orange ( Fig. 7View FIGURE 7 F)........................................
