DIAGNOSIS: Most similar in appearance to C. hallodapoides, based on attributes also seen in many Hallodapus spp., including the matte surface texture and weakly elevated pronotum, unlike other species placed in Cyrtopeltocoris, most of which have a mostly highly polished and moderately to strongly convex pronotum. Apex of the endosoma superficially similar in C. brailovskyi and C. hallodapoides but with significant differences in detail, as seen in figures 1 and 2.

DESCRIPTION: Male: Total length 4.11. Coloration (fig. 1): Head dark reddish brown; antennae dark reddish brown; labium brown; pronotum dark reddish brown; mesoscutum and scutellum dark reddish brown; scent-gland auricle brown; clavus orange brown basally, ivory medially and brown apically; corium and embolium brown apically and basally, ivory medially; transverse ivory band on corium and clavus well demarcated and complete except for costal vein, weakly offset posteriorly at claval suture; corium with a quadrate ivory patch apically at cuneus; cuneus reddish; membrane fuscous; venter brown; mesepisternum dark reddish brown; procoxae dark reddish brown, mesocoxa and metacoxae dark reddish brown, trochanters ivory; femora and tibiae dark reddish brown; tarsi brown (fig. 1). Surface and vestiture (fig. 1): Head, pronotum, and scutellum dull, distinctly granular; vertex, pronotum, and scutellum with short recumbent setae; corium with recumbent and long, erect, simple setae (fig. 1); antennae with short recumbent setae (fig. 1). Structure: Elongate, parallel sided; pronotum trapezoidal, posterior lobe moderately elevated, weakly tumid (fig. 1); scutellum not swollen or elevated; corium with lateral nearly straight; labium reaching onto abdominal sternum 3. genitalia (fig. 4): Endosoma moderately long, forming a complete coil; apex largely membranous with a wrinkled ventral surface and a finely serrate apical margin (fig. 4); phallotheca and parameres as in generic description.

ETYMOLOGY: Named for the collector, Harry Brailovsky, in recognition of his seminal contributions to heteropterology in Mexico.

DISTRIBUTION (fig. 6): Known from Oaxaca, Mexico.

DISCUSSION: This is the only species of Cyrtopeltocoris known from mainland southern Mexico. As noted in the diagnosis, it shares several aspects of morphology with C. hallodapoides from Baja California, including the dull granular texture of the head, pronotum, and scutellum, the somewhat flattened (as opposed to tumid) pronotum, and the structure of the apical portion of the endosoma.

HOLOTYPE male: MEXICO: Oaxaca: Tamazulapan, 20 Oct 1978, H. Brailovsky (AMNH _ PBI 00414819) (UNAM).
