Eggs were obtained from female Argas (Persicargas) miniatus parasitizing chickens after natural ovoposition. The larvae from eggs were sacrificed, prepared for and mounted onto slides. Morphological and chaetotaxic studies enabled the following observation: idiosome and gnathosome shape; presence or absence of scutum, eyes and anal setae; number of palpi segments; number of files of teeth on the hypostoma; number of denticles on the apical crow; number of cheliceral digits; number of teeth in each hypostoma file; disposition and shape of opistosoma and podosoma setae in ventral and dorsal view. Based on these morphological features analyzed, it is concluded that the larvae of A. (P.) miniatus present variations in morphology and chaetotaxy that are useful to separate the larvae of the subgenus Persicargas.
