Remarks
Pupae of S. variegatum are easily identi®ed by the pair of large oval protuberance s positioned anterodorsall y on the thorax between the gill bases. These structures were ®rst recorded by Puri (1925), who referred to them as patagia, a term by which they are still sometimes known in simuliid literature. However, we prefer to call them`thoracic bosses’, considering patagia an inapproriate term in the black¯y context: patagium is a term applied by lepidopterists (from whom Puri took it) to a lateral lobe of the adult pronotum, and applied by zoologists to a web or fold of skin in ¯ying and gliding vertebrates. The function of the thoracic bosses, unique to S. variegatum (and some immediate nominal allies of dubious validity), is unknown. They are present throughout the pupal/pharate adult life, stand up prominently when the pupa is seen in pro®le (®gure 45) and are very conspicuous on pupal exuviae (®gure 44).
The species is common in stony streams and rivers in the upland areas of Andalusia.
