Abstract

Gynandromorphism is a developmental anomaly characterized by the simultaneous presence of male and female morphological attributes within the same individual. This study documents the first case of gynandromorphism in the cattle tick Rhipicephalus microplus (Canestrini 1888) in El Salvador. The specimen was collected from a bovine belonging to the Experimental and Practical Station of the Faculty of Agronomic Sciences of the University of El Salvador, located in the municipality of San Luis Talpa, Department of La Paz. The reported gynandromorph of R. microplus exhibits bilateral symmetry, displaying primarily female characteristics on the left side and male characteristics on the right.
