Diagnosis

Externally most similar to E. poppii and E. fuscomaculata , but the saw fits best with E. scotonota , which has 16–17 serrulae (12–15(?) in E. fuscodorsata ) and largely black head (pale around eyes and pale supraclypeal area in E. fuscodorsata ). The claws of E. fuscodorsata are not clearly bifid as in most other Euura (including E. poppii and E. fuscomaculata ) but have a small or large subapical tooth. We have studied only three females. Characteristic for the species may be pale sterna in combination with black downturned parts of abdominal terga, although this colour pattern does occasionally occur in some other species as well, like E. poppii and E. fuscomaculata .
