Type material

Holotype male: Brazil, Rio de Janeiro. Itatiaia. Retiro de Itatiaia (Retiro do Ramos, Parque Nacional de Itatiaia , about 2200 m). Carlos Moreira leg. 1903. Museu Nacional, Rio de Janeiro (1410), not examined.

Notes

Hapalotremus cyclothorax was described by a single male from Retiro de Itatiaia (Rio de Janeiro, Brazil) ( Figure 4 View Figure 4 ) and the type material has been listed as “not located” in the annotated check list by Silva-Moreira et al. (2010) of Arachnida type specimens deposited in the Museu Nacional, Rio de Janeiro. It is possible that it could be a junior synonym of Cantanduba tuskae Yamamoto et al. (2012) , Oligoxystre mineirum Guadanucci 2011 or Magulla obesa Simon, 1892 , considering the overlapping of their geographical distributional range in the Atlantic forest ( Indicatti et al. 2008; Guadanucci 2011; Yamamoto et al. 2012). However, H. cyclothorax differs from C. tuskae , O. mineirum and M. obesa in the colour pattern, the size of the body and legs and in the shape of the palpal bulb (Mello-Leitão stated in the original description that the male has a bulb with twisted embolus). Another species that overlaps its distributional range with H.cyclothorax is Homoeomma montanum ( Mello-Leitão, 1923) ( Gerschman de Pikelín and Schiapelli 1972, Yamamoto unpubl. data). Moreover, the type locality (Retiro de Itatiaia) of H. montanum is the same for H. cyclothorax and additionally, both specimens were captured by the same collector, Carlos Moreira ( Gerschman de Pikelín and Schiapelli 1972). The length of body and legs of the male H. cyclothorax is consistent with that of H. montanum . The colour pattern with abdomen dark bearing numerous long reddish setae, the tibial apophysis with two branches bearing short apical spines, the bent metatarsus I and the shape of the bulb with a curved embolus are characteristics typical of Homoeomma species ( Gerschman de Pikelín and Schiapelli 1972, Yamamoto unpubl. data). For these reasons, Hapalotremus cyclothorax is considered a junior synonym of Homoeomma montanum .
