A new species of Paranthaclisis Banks (Neuroptera, Myrmeleontidae) from the Peninsula of Baja California, Mexico

ABSTRACT Paranthaclisis stangei Marquez, Martins, and Contreras, sp. n., is a new myrmeleontid from Baja California Sur state, Baja California Peninsula, Mexico, which is an important area of endemism. After this new discovery, the genus Paranthaclisis is composed by five species, three occurring in Mexico. This new species is easily identified by a rostrum completely yellowish-white, an area of pre-origin of RP with spurial vein on hindwing and with marks; males are easily separated by the conspicuous posterior thinning of the parameres and mediuncus dorsally without teeth and a basomedial split.
