Description (male)
Head. Eye bridge 3–5 rows of facets. LW-index of 4th antennal flagellar segment 2.9–3.6; Transition of basal part to neck bottle-neck-like. Palpomeres 3. First palpomere with numerous bristles; with only some sparse sensillae. Thorax. Thoracic setae strong or normal. Posterior pronotum usually setose. Laterotergite bare. Legs. Frontal tibia with a patch of setae. Front tibial organ mostly dark. Front tibial organ not bordered. Tibial spurs elongate, of equal length. Claws untoothed. Wings. Wings darkened, of normal shape. Wing membrane with macrotrichia. Wing venation normal. M-fork of normal shape. R1 inserting at or slightly before base of m-fork; posterior veins mostly with macrotrichia. Halteres of normal length. Abdomen. Abdominal setae normally strong and dense. Hypopygium concolour with abdomen. Inner margin of gonocoxites normally U-shaped; inner part of hypopygium densely setose; elongated setae on valves of hypopygium absent. Gonostylus elongate; inner margin straight, or concave. Apical tooth usually present. Apical awl-like setae present. Megasetae on inner part of gonostylus absent. Tegmen rounded; central process absent. Measurements. Body size 2.5–3.8 mm. Wing length 2.4–3.8 mm.
Diagnosis
Hirtipennia belongs to the basal subfamily Sciarinae together with Sciara, Trichosia, Trichosiopsis and Leptospina. In contrast the other genera Hirtipennia has macrotricha on the wing membrane. Only Sciara may have a few macrotichia near the wing tip. Like in Sciara, also in Hirtipennia the flagellomeres have bottle-neck-like necks and the legs are only weakly setose.
Etymology
lat. hirtus = bristly; pennis = wing. The name refers to the macrotrichia on the wing membrane.
Discussion
Hirtipennia was originally defined by as a subgenus of Leptosciarella (now named Trichosiopsis) because of the presence of an apical tooth at the gonostylus. However, the tooth is not present in all species. As already indicated by Mohrig & Menzel (1997)[1] and Rudzinski (2005)[2], Hirtipennia is more closely related to Sciara than to Trichosiopsis and therefore to be treated as a distinct genus.
Distribution
Species of this genus have a Holarctic distribution.
