Simulium paraloutetense Crosskey, 1988

Gran Canaria blackfly (proposed)



Taxonomy & Nomenclature



Conservation Status


Last record: after 1994


The Gran Canaria Blackfly (Simulium paraloutetense) was long known only from specimens collected in 1931 from Las Lagunetas, Gran Canaria, by Finnish entomologist R. Frey (Crosskey, 1988; Crosskey et al. 1999). And when (Crosskey, 1988) described the species he believed that no springs remained on Gran Canaria, and hence this rare endemic was extinct. Thankfully, however, as the paper was going to press the species was rediscovered by Marco Báez (Crosskey, 1988:355). Additional specimens were subsequently collected at all stages of the lifecycle and these were described by (Crosskey et al. 1999). However, the species was again reported as probably extinct by (Crosskey & Báez, 2004) on account of its only known remaining habitat being destroyed.
