Brachymeria subrugosa Blanchard, 1942 

( Fig. 8View FIGURE 8 A −E)

Brachymeria subrugosa Blanchard, 1942: 116  −117. Original description ♀. ARGENTINA: Charata. 

Brachymeria subrugosa  ; De Santis 1967: 209 [host Pectinophora gossypiella  and Patelloa  ( Tachinidae  )]; De Santis 1979: 63 [host Eucelatoriopsis  sp. ( Tachinidae  )]; Aquino et al. 2015: 297 View Cited Treatment [lectotype designation].

Material examined. PARAGUAY. Colonel Delgado , ex Alabama argillacea [ Lepidoptera  : Noctuidae  ] on Gossypium hirsutum  , 30.v.1985, adult emergence 06.vii.1985, Michel B. leg. (1 ♀) [Ref. Cirad 5246] (in CIRAD). 

Diagnosis. Mandibles brown subapically ( Fig. 8View FIGURE 8 B). Epicnemium and prepectus black, only ventral prepectus on sides of medioventral projection dark brownish. Black ring on mesofemur complete. Head about as broad as mesosoma. Gena, lower face and supracoxal stripe of metepimeron moderately setose ( Fig. 8View FIGURE 8 A, B). Clypeus with irregularly distributed points ( Fig. 8View FIGURE 8 B). Adtorular carinae thin, appearing as irregular rugae ( Fig. 8View FIGURE 8 A, B). Antennal scrobes reaching lower margin of median ocellus, virtually as high as eye (0.97×) their upper edge at level with upper ocular line ( Fig. 8View FIGURE 8 A). Eyes separated by 0.9× their own height ( Fig. 8View FIGURE 8 A). Ocellar ocular distance much shorter than median ocellus diameter (as in Fig. 5View FIGURE 5 A). Clava tapering with small area of micropilosity ( Fig. 8View FIGURE 8 E). Mesosoma 1.35−1.4× as long as broad. Basal fold of fore wing with 12 or 13 setae. Metasoma 2.01−2.26× as long as broad. Apex of hypopygium emarginate mesally (as in Fig. 5View FIGURE 5 J).

Recognition. This species is easily separated from B. subconica  and Brachymeria  'Brassolis' by the smaller number of setae on the basal fold. It is distinguished from B. philornisae  and B. costalimai  by the antennal scrobes being virtually as high as the eye such that the upper edge is about level with the upper ocular line.

The ratios provided by the LDA extractor are also useful (Tab. 4 and Fig. 4). The ratios of head breath: frontovertex breath and mesoscutellum breath: median ocellus diameter readily separate it from B. subrugosa  while the ratios of metasoma length: mesosoma length and head breath: eye height distinguish it from most specimens of B. costalimai  .

Hosts. The type series and the female examined were both from Alabama argillacea (Hübner) ( Lepidoptera  : Noctuidae  ). The tachinid hosts quoted by De Santis (1967, 1979) must be checked because of the past confusion concerning the identity of the species. This species was erroneously quoted as B. subconica  by Silvie et al. (2014) and at least some of the hosts cited by the authors are probably erroneous because the species was mixed with B. costalimai  as noted above.

Distribution. Argentina and Paraguay.
