In the Japanese Insect database there are only three entries. And nigricans is not present. Is that a non-valid species name or a synonym?
I think No2. is nigricans.(仆灼牧奔諺舗エ)
So I think No.1 is not nigricans.But I do not know the species. About No.3 and No.4,I think they are basilaris,too. (冏蔚論湫舗エ) Please make sure.
なんか、文字化けしてますね
2はミスジヒメヒロクチバエ。3.4.はムネアカマダラバエ ではないかと思います。(思っているのです) ムネアカの方は、腹部後半節の色彩がもっと黒いのが普通と思いますが、変異の範囲か?違う種か?標本見ないとここまでですね。
一応注意事項には出てるのですが、
半角カナ文字だと文字化けします。
Thx.
I think maybe 1 and 2 are the same species. I made the picture at the very same location, though Image 1 is from 2oo4 and Image 2 is from 2oo5. The two images are very similar, except the black markings on the wings are much stronger on the fly shown on Image 1. Maybe it is a gender difference, or individual variation. |
