Hi, does anyone know where I can find a description of Alliopsis maculifrons (Zetterstedt, 1838) or a key that includes this species?

The original description, as Anthomyza maculifrons, is on page 672 of Insecta Lapponica at https://www.biodi...raphy/8242. If it's a purely Palaearctic species I don't have any modern works.

I asked Verner Michelsen who sent me this identification key:

Males
1 Vein C with a few v-setulae immediately distal to insertion of vein R1. Fore tibia with four apical setae in d, pd, p and pv position. Longest pv-setae of hind femur slightly exceeding depth of femur Alliopsis silvestris
– Vein C with scattered v-setulae reaching far distal to insertion of vein R1. Fore tibia with three apical setae in d, p and pv position. Longest pv-setae of hind femur shorter than depth of femur 2
2 Longest aristal pubescense distinctly longer than basal diameter of arista. Male: Frons at narrowest point not exceeding width of ocellar tubercle Alliopsis silvatica
– Longest aristal pubescense equal to basal diameter of arista. Male: Frons at narrowest point wider than ocellar tubercle Alliopsis maculifrons
Females
1 Frons at narrowest point less than 1.5 times as broad as ocellar tubercle, with 0–1 pair of orbital setae. Fore tibia with 4 apical setae in d-, pd-, p- and pv-positions. Vein C with v-setulae barely extended distal to insertion of vein R1 Alliopsis silvestris
– Frons at narrowest point at least 2 times as broad as ocellar tubercle, with 2 pairs of orbital setae. Fore tibia with only 3 apical setae, seta in pd-position absent. Vein C with v-setulae extended far beyond insertion of vein R1 2
2 Aristal pubescence distinctly longer than greatest basal diameter of arista. Fore tarsomeres 2–3 moderately expanded Alliopsis silvatica
– Aristal pubescence no longer than greatest basal diameter of arista. Fore tarsomeres 2–3 strongly expanded Alliopsis maculifrons

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
