Species known from North America:
S. albonotatus (Texas to New Jersey; mostly black, thorax with whitish spots)
S. ater (Northeast; mostly black, wings darkened)
S. debilis (Southeast north to New Jersey)
S. frosti (Florida)
S. hyalinus (Southeast north to Long Island)

Most of these species are listed in Coquillett's 1896 revision and Melander's 1902 paper. Melander 1928(1) has a checklist and some new species descriptions but no key. A few more species were described in 1974; that revision is not available in electronic form.
