Groundwater and marine intertidal Tubificidae (Oligochaeta) from the Canary and Cabo Verde Islands, with descriptions of two new species
Bijdragen tot de dierkunde , Volume 62 - Issue 2 p. 63- 70
Seven species of Tubificidae are recorded from the Canary Islands, viz. Heterodrilus amplus n. sp., Coralliodrilus leviatriatus Erséus, 1979, Limnodriloides agnes Hrabĕ, 1967, L. janstocki n. sp., Aktedrilus cuneus Erséus, 1984, A. parvithecatus (Erséus, 1978), and Tubifex tubifex (Müller, 1774); the two latter taxa are reported also from the Cabo Verde Islands. All taxa except T. tubifex are marine and there is no evidence of endemism in the freshwater oligochaete fauna of these islands. Heterodritus amplus has short, spindle-shaped, heavily muscular atria; they are morphologically unique within the genus. Limnodriloides janstocki has modified spermathecal setae; it is distinguished from similar species by its long atrial ducts and deep, elaborate copulatory sacs.
