Abstract: The type species of the Neotropical Actinopus, A. tarsalis Perty, 1833, is redescribed based on material from the type locality, the state of Piauí, Brazil. The species appears to be restricted to northeastern Brazil and is newly recorded from the state of Sergipe. An old record from the state of Rio Grande do Sul is rejected. Actinopus tarsalis differs from other species of the genus by details of the male copulatory bulb: tegular apophysis absent, robust embolar base, inserted basally at a right angle (90°);… Show more

“…We do not find any SPB or β Cep modes to be excited in models at the SMC metallicity, Z = 0.00236. This is not surprising since opacity profiles with a scaled solar or a B-SMC mixture are very close and since results with solar mixtures already indicated no excitation at such a metallicity (Miglio et al 2007a). In addition, we have made grids of models with the same physics, but with a metallicity of Z = 0.005 and 0.01.…”

“…The MCs are a very convenient place to observe not only the effects due to a different chemical mixture but also those coming from a low metallicity. The results of Miglio et al (2007a) predict a limited number of SPBs and no β Cep stars in the MCs. These results are challenged by recent detection of a significant number of B-type pulsator candidates in the MCs, and particularly in the SMC, the most metal-poor cloud.…”
