Abstract


Transitia carlosi n. gen. n. sp. of the family Lethaxonidae is described from the interstitial environment of a small stream in Central America. Following a morphological revision of the adult variation in the family, Transitia n. gen. is proposed, characterized by a posteriorly tapering body shape, three pairs of acetabula arranged linearly, median position of male gonopore in relation to first pair of genital acetabula and slight sexual dimorphism of male legs.
