Abstract
Diplothyrus lehtineni n. sp. is described from adults females and males collected on surveys in the Brazilian Amazon forest. Measurements and illustrations of both sexes are provided. The presence of two modified setae on the palp genu, the absence of fringed seta on the palp genu and the absence of complex branched outgrowths on the chelicera characterizes this species. A description of Haller’s organ solenidia is also presented.
Highlights
Records of Neothyridae are limited to the Neotropical region, including Neothyrus ana Lehtinen 1981 from Peru, Diplothyrus schubarti Lehtinen 1999 from Brazil, Caribothyrus barbatus Kontschán & Mahunka 2004 from Dominican Republic and Diplothyrus lecorrei Klompen 2010 from French Guiana
The only recorded species is D. schubarti, based on a male collected from Amazonas state and females from Para state (Bernardi et al 2011)
The poorly made descriptions of Neothyridae species makes difficult to a proper comparison to D. lehtineni, besides their diagnoses are enough to confirm the new taxon
Summary
Records of Neothyridae are limited to the Neotropical region, including Neothyrus ana Lehtinen 1981 from Peru, Diplothyrus schubarti Lehtinen 1999 from Brazil, Caribothyrus barbatus Kontschán & Mahunka 2004 from Dominican Republic and Diplothyrus lecorrei Klompen 2010 from French Guiana. In Brazil, the Amazon forest is considered a biodiversity hotspot (Lewinsohn et al 2005), but the distribution of many groups of mites, including http://www1.montpellier.inra.fr/CBGP/acarologia/ ISSN 0044-586-X (print). ISSN 2107-7207 (electronic) to Neothyridae, is still poorly known. The only recorded species is D. schubarti, based on a male collected from Amazonas state and females from Para state (Bernardi et al 2011). Material collected in a survey in Para state allows us to describe here a new species of this poorly known group
