Abstract

Sperberacris, a new Neotropical genus of Amblytropidiini. Sperberacris muriciensis n. sp. (type species) from the municipality of Murici, State of Alagoas, Brazil is described. The new genus differs from other tribe congenera by the epiproct suboval, furculae divided into four long sclerotized lobes, cerci curved inward, apex truncated and sclerotized at the tip and convex bridge of the epiphallus with two large black sclerotized spots. The new species presents a diploid number of 2n = 23, X0♂/24, XX♀, and the karyotype is made up of telo/acrocentric chromosomes, with one dot-like B chromosome occurring in some nuclei. Morphological descriptions are provided along with illustrations emphasizing the most significant diagnostic features of external morphology and male genitalia. Information on type specimens, material examined, and distribution provided.
