Eric is totally correct, but be warned all features are variable and some species seem genually intermediate. Width of vertex in male and esp. shape of male genitalia are highly distinctive. So never base your ID on one feature only ( unless male genitalia) That said, this is rock solid female fera, indeed. Theo. |
