With such a precise description, you should have the answer, haven't you ?
Stephane. |

Stephane, I presume you favour evecta? My problem was that the hairs below the scutellum seemed pale rather than dark as required and the outer cross-vein infuscation was very slight. The hairs may have been dark enough under ideal lighting conditions - I see that no species has the scutellum hairs exactly as I descibed. Is this right? Phil Porter |

If there are hairs under scutellum, and not only at the ventral margin, I would consider it is H. evecta. Are av present also on basal half of hind femur ?

Stephane, there is a long line of a/v's on the apical 80% on hind femora (out of focus below leg) but not in basal 20%. Is that sufficient? Regards Phil philporter attached the following image:  [94.68Kb] |

It is sufficient (with the previous characters).
