Whether this is a species in its own right or a subspecies of S. striolatum (Common Darter) seems to be open for discussion. For now, I’m showing it as a species. These are residents of the Madeira Islands and the Canary Islands and exhibit minor differences to S. striolatum, the most visible of which (to the casual observer) is darker femurs showing less of a yellow stripe.
Id Notes
- lower legs black with yellow streaks but femurs mostly black
- ♂ – contrasting brown and light yellowish panels on side of thorax
- mature ♂ – abdomen more orange in appearance than the very red S. sanguineum
- ♀ – yellow abdomen, darkens to dull olive/greenish with age (normally)
| mature female |
