| "Bear Swamp," PA Posts: 1003 | The row of spinules across the back of the head in combination with the presence of anal gills indicates that Agnetina is the likely genus; and the dorsal pattern appears to be classic capitata. | |

| Clifton Park, NY Posts: 1 | Just to add to Gonzo's assessment of characteristics, A. capitata is identified most definitively by looking at the dark pigment on tergum 10 as well as the head pattern. With this species, the pigment band on tergum 10 is uninterrupted (though it narrows quite a bit). The head "M line" is nearly lateral, as apposed to A. flavescens, for example, which really looks like an M with posterolaterally directed arms. | |
