Contreras, E. Hijmensen, E. Goyer.

Emended diagnosis: The following character combination is diagnostic for H. eros . Male palpal bulb with slender embolus similar in length to tegulum, SA ends at embolus base; VG shallow ( Fig. 8A–D ). Metatarsus I curved ( Fig. 7E ). Rap is normally developed with one large spinose seta on ventral face, the spinose seta exceeds the apex of Rap ( Fig. 7F, G ). Males with spinose setae on patellae I to IV, which are absent on females. Ocular tubercle and eyes normally developed and periocular pigmentation complete ( Figs 7A ; 9A, C ). Urticating setae arranged in one dorsomedian patch, yellowish-orange in colour with well-defined margins; posterior margin slightly notched, forming a furrow ( Figs 7C , 9B ). Spermathecae paired, slightly fused; receptacles broad at base; slightly bent laterally ( Fig. 9D, E ). Hemirrhagus eros differs from most Hemirrhagus species by the male having spinose setae on patellae I to IV. It differs from H. benzaa sp. nov. and H. guichi sp. nov. by the spermathecae having the receptacles widely separated at the base by nearly one length, slightly bent laterally and by the SA ending at embolus base.

Distribution and habitat: Known only from El Punto, Oaxaca ( Fig. 48 ), inhabits pine forest ( Fig. 2K ).
