| Mercer Island, WA Posts: 484 | Jason- Your identification appears spot on. You may well have already considered them, but here are three key matches: 1} Genitalia illustrated in Leonard & Leonard p. 125 figure 75, which seems to match the claspers perfectly, and would likely match the penes perfectly as well, were they not a bit damaged 2) Sternites "with four small dots sometimes elongaged into narrow streaks" as described in Leonard & Leonard p. 50 3) "stigmatic area of fore wing milky" as described in Leonard & Leonard p. 50 | |

| Fairbanks, AK Posts: 1115 | Thanks for double-checking me. It's that much more convincing, now, because I arrived at needhami by different means. I used the keys from Allen & Edmunds' revision of the Ephemerellidae, though they can be a bit difficult to follow. | |
