Abstract
ABSTRACT A new species of the pseudoscorpion genus Cystowithius Harvey, 2004 is described based on several males and females collected in the Cordillera Central near Manizales and Villamaria, Caldas, Colombia. The type series was collected under or on the bark of Eucalyptus grandis W. Hill ex Maiden (Myrtaceae). Cystowithius ankeri sp. nov. is the fifth species in the genus, differing from its four congeners by several characters, including the position of the male sternal invaginations, the length of the movable finger of the pedipalp, and the tactile setae of tarsus IV situated subdistally. A revised identification key to the five species of Cystowithius is also presented. The first barcode (COI gene) of a species of this genus is also provided.
Highlights
MATERIAL AND METHODSThe cheliferoid family Withiidae Chamberlin, 1931 comprises 37 genera in two subfamilies: Paragoniochernetinae, restricted to southern Africa, and Withiinae, distributed worldwide (Harvey 2015)
Cacodemoniini is the only group of the Withiinae that can be characterized using morphological characters, more precisely, by the separated lateral rods and a long ejaculatory canal formed not by the dorsal apodemes exclusively, but by a fusion of the dorsal and lateral apodemes (Romero-Ortiz and Sarmiento 2021)
The specimens were collected in 2018, 2019 and 2021, in the Jardín Botánico, Universidad de Caldas (5.055°N; 75.494°W) in Manizales, and Vereda Gallinazo (5.015°N; 75.439°W) in Villamaría, both located in the Colombian department of Caldas
