I'd go with Hebecnema too. It seems that halters knobs are black, therefore I'd say Hebecnema nigra (and only 1 av on t3 ?). Stephane. |

I am very new in this business. Is it possible to explain, what 1 av on t3 is? I know t3 is tergit 3 and av means anteroventral. I have manipulated the contrast on the last picture. Does it help? Kindly regard Ruth Ruth Ahlburg attached the following image:  [67.27Kb] |
