A new genus and species of long-legged crickets (Grylloidea, Phalangopsidae) is described from Cuba, using characters of general morphology and male genitalia. Matildacris gageae Desutter-Grandcolas gen. nov., sp. nov. is characterized by the absence of glandular structures in male genitalia, the presence of a strong and acute pseudepiphallic 'C-sclerite', and two strong parts, equally developed, in the pseudepiphallic parameres, among other characters. Its forewings are devoid of a stridulum and the left forewing presents a strong diagonal desclerotized groove, a feature not previously observed in crickets; by analogy with other insect orders, this character could keep the wings in the closed position. We compare the genitalia structures of Matildacris Desutter-Grandcolas gen. nov. to other Neotropical Phalangopsidae taxa and discuss their diverse forewing conditions.
