Emended diagnosis: The following character combination is diagnostic for H. chilango. Male palpal bulb with slender embolus similar in length to tegulum, SA ends at embolus base (Fig. 4A, D); VG deep (Fig. 4B). Embolus strongly curved retrolaterally on distal half (Fig. 4C, D). Pap reduced with one slender spinose seta ventrally that does not exceed the apex of Pap; Rap is narrow with one large spinose seta on dorsal face, the spinose seta exceeds the apex of Rap (Fig. 3G, I). Metatarsus I almost straight (Fig. 3H). Ocular tubercle and eyes normally developed, periocular pigmentation complete (Fig. 3A, D). Labial cuspules are highly variable in number, ranging from 16–38 (Fig. 3B, E). Urticating setae arranged in two lateral, oval patches, black in colour, with well-defined margins (Fig. 3C, F).
Hemirrhagus chilango differs from most Hemirrhagus species in having the urticating setae arranged in two lateral patches. It differs from H. perezmilesi by having the tibial apophyses well developed. Differs from H. valdezi sp. nov. by oval patches of urticating setae with well-defined margins rather than diffuse, and metatarsus I straight rather than curved.
Distribution and natural history: Known only from Mexico City (Fig. 48); inhabits shrubland and pine forest (Fig. 2F).
