I think the most probable version is Rhaphium appendiculatum Zetterstedt, 1849: Dipt.Scand. 8: 3058 ** Type locality: Sweden: Scania ad Esperod. Palaearctic: Sweden, Finland, England, Ireland, Denmark, Netherlands, Germany, France, Austria, Italy, Spain, Hungary, Bulgaria, Poland, Czechoslovakia, Romania, Russia, Ukraine, Middle Asia, Iran, Afghanistan, Algeria, Morocco; Afrotropical: St. Helena // syn. of Rhaphium macrocerum Meigen, 1824 (Parent, 1925: Enc.ent. (B II) Dipt. 2: 41-42); rest. Collin, 1940: Ent.monthly Mag. 76 [= 4(1)]: 266-267 * Igor Grichanov |

thank you very much Jorge and Igor. I'll name it Rhaphium appendiculatum and put a questionmark after it. As anyone can confirm this id, you are welcome! Robert, |

Welcome to everybody to check the species distribution in their countries. Or maybe all Rhaphiun species http://grichanov.fortunecity.com/wPterostylus.html#Rhaphium Multiple male colour and morphological ornaments (male secondary sexual characters or MSSC) are commonly found on antennae, mouthparts, legs, wings and abdomen in many Dolichopodidae species in addition to large genital capsule (hypopygium). This decoration developed more in tropical species marks out long-legged flies from all other Diptera (Sivinski, 1997). Igor Grichanov |
