Abstract

Two new species from the superfamily Crotonioidea, Malaconothrus kawensis n. sp. and Cyrthermannia bifurcata n. sp., found in material colected in Kaw mountains (Montagne de Kaw), and near the Saül, French Guyana, are described. The relationships of both new species within respective genera are analysed, and determination keys are provided for all South-American and other closely related Malaconothrus species and for all known Cyrthermannia species. Cyrthermannia formosana Tseng, 1982 is newly recombined as Nanhermannia (Nippohermannia) formosana (Tseng, 1982) n. comb., following analysis of morphological characters.

Highlights

The oribatid fauna of French Guyana was completely unknown, with no published information before my previous work referring to mites from the family Rhynchoribatidae (Miko, 2016)
In this second contribution on oribatids of French Guyana, the aim is to describe two new species from the superfamily Crotonioidea Thorell, 1876 Malaconothrus kawensis n. sp. and Cyrthermannia bifurcata n. sp., found in material collected in Kaw mountains (Montagne de Kaw) and in the vicinity of Saül, respectively, and to analyse their relationships within their relevant genera
Material studied for this publication was collected in the range of Kaw Mountains (Malaconothrus kawensis n. sp.) and in the vicinity of Saül (Cyrthermannia bifurcata n. sp.)
