New species describes unique traits in a species of Mastigoproctus from Jalisco, highlighting biodiversity.
In this contribution, we describe a new species from the Estación de Biología Chamela (IBUNAM), located in Jalisco, Mexico. Mastigoproctus claritae sp. nov. has a stridulatory organ like M. mexicanus and M. xetame. However, it is distinguished from these species by the presence of a proventral marginal smooth keel in the chelicerae, a retrolateral surface pedipalp femur with congregated and blunt cristulae, a prodorsal margin spine S3 that is longer than the other spines in males, and symmetric, peanut-shaped spermatheca seminal receptacles in females. Mastigoproctus claritae sp. nov. represents the twenty-third species of the genus and the twelfth species documented in Mexico.
