| Indiana Posts: 199 | Looks similar to the genus Tricorythodes (what people call Tricos) or some other member of the family Leptohyphidae. The dark color, three tails and shape & coloration of wings all help me to guess that it is Tricorythodes. How big was it? What part of Mexico were you in when you saw it? | |

| Posts: 9 | It is small maybe 1.4 cm I saw it in the central part of mexico, the place is about 2000 mt above the sea level, it was a beautiful shinny black color | |

| Indiana Posts: 199 | Several Tricorythodes species are known from central Mexico. http://www.entm.purdue.edu/entomology/research/mayfly/species.html Did you see the river or stream nearby? If so, please describe it. This might help. | |

| Mercer Island, WA Posts: 475 | Xavier_Carp- When you say Central Mexico, are you referring to the country or the state of México? This information would allow me to significantly narrow down the identification possibilities. Here is a list of the Mexican states:

| Mercer Island, WA Posts: 475 | Hmmmm. Puebla, doesn’t seem have any leptohyphids recorded, at least according to a list compiled from Dr. Pat Randolph’s PhD dissertation. So, I looked at the surrounding states, and found that Oaxaca, immediately south of Puebla, has records of the following leptohyphids:
Leptohyphes brunneus Leptohyphes castaneus Leptohyphes zalope Tricorythodes notatus Vacupernius packeri It is likely one of these. Perhaps Konchu will be able to narrow it further. | |
