| Abstract |
A new species of freshwater tubificid worm is described from the East Pacific Coast of Central America. Monopylephorus camachoi nov. sp. is mainly characterised by the presence of a single spermatheca with a short bulbous muscular duct and a pair of relatively elaborated male ducts, each consisting of a short vas deferens, a prostate-covered tubular atrium that opens apical-laterally to a muscular ovoid cavity interpreted as a pseudopenis, separated by a constriction from an elongated penial bursa. Pseudopenes and penial bursae have thick muscular walls arranged in two perpendicular layers. Both male ducts open into a mid-ventral copulatory bursa in segment XI. Setae in ventral bundles of both spermathecal (segment X) and postatrial (segment XII) segments are enlarged. |
