First detection and a new avian host of the tick Ixodes ventalloi Gil Collado, 1936, in Slovakia

Abstract

This study describes the first detection of Ixodes ventalloi in Slovakia. Two engorged females of I. ventalloi were collected from Dunnocks (Prunella modularis) captured in eastern Slovakia. The identification of females was based on morphological and molecular 16S rRNA gene features. Phylogenetic analysis revealed a classification of the females into distinct genogroups. Moreover, comparative morphological analysis highlighted variations between the two females, particularly in the curvature of the auriculae, the shape of coxa I, and the internal spur. These findings suggest the potential for varied phenotypes of I. ventalloi correlated with their genogroups. Nonetheless, I. ventalloi population establishment within Slovakia necessitates further investigation through flagging or drag sampling.
