Diagnosis
Hirtipennia holotricha is similar to Hirtipennia hirtipennis and can be distinguished by the smaller size, the less tapered gonostyli and the missing macrotrichia between the veins c and r5. Mohrig & Menzel (1997[1]: 48) mentioned the presence of some hairs on the mediotergite of the of the holotype, the only available specimen at that time. This character seems to be stable for the Le. holotricha, because it is present in all studied specimens.
DNA Barcoding
The COI sequence is assigned to BIN BOLD:ADR3348 (average distance 0.16%, max. 0.16%, n=2, K2P: 10.13%).
Etymology
gr. ὅλο- (holo-) = complete, θρίξ (thrix) = hair; making reference to the completely setose wings.
Ecology
Hirtipennia holotricha may be common in urban ecosystems.
Distribution
Finland[2], Germany[1][3], Netherlands[4], Sweden[5].
