Abstract

We describe a new species of the genus Clathrosperchonella, C. olovi sp. nov. from Brazil, including complete information for female, male and larva. This brings the number of named species in the Rhynchohydracaridae to thirteen. In addition, we provide a key to named species of Clathrosperchonella.

A new species of Rhynchohydracarus Lundblad 1936 (Acariformes: Hydrachnidiae: Hydryphantoidea: Rhynchohydracaridae) from central Brazil, with DNA barcodes, a key for known species and a proposal for the homologies of dorsalia, ventralia, lateralia and glandularia for the family

“…Similar to vgl-1, vgl-3 are ventral and positioned posterior to the excretory pore and on the paired v-4 (Fig. 6B); however, Lundblad (1941) described the latter as just "vgl" for Clathrosperchon crassipalpis Lundblad, 1936 andonly "v" for Rhynchohydracarus testudo, andCastro et al (2020) described vgl-2 as being vgl-1 for Clathrosperchonella olovi Castro, Proctor & Lofego, 2020. Here we correct these mistakes.…”

“…The Rhynchohydracaridae is a water mite family that inhabits riffles, springs, and streams in the New World (Cook 1974; Goldschmidt 2004, 2006, 2009; Goldschmidt et al 2016; Proctor et al 2015; Goldschmidt and Ramírez-Sánchez 2020 and is composed of three subfamilies: Rhynchohydracarinae Lundblad, 1936, Clathrosperchontinae Lundblad, 1936, and Santiagocarinae Valdecasas, 2001(Walter et al 2009; Goldschmidt and Ramírez-Sánchez 2020; Smit 2020. For a brief checklist of all genera, species, type localities, and known distribution see Castro et al (2020). The monogeneric subfamily Rhynchohydracarinae is considered endemic to the Neotropical region (Di Sabatino et al 2008) and, until now, has included only three species in the genus Rhynchohydracarus, with sparse and distant localities of occurrence (Fig.…”
