Dicranomyia (Microlimonia) Savchenko, Krivolutskaya,
1976: 147-148; Savchenko, 1983: 138; 1985: 125-126;
1989: 311-312. Atypophthalmus (Microlimonia) Geiger, 1986: 53 . Type species - Limonia inelegans Alexander, 1924 (original designation).
General: Medium-sized crane flies, body length 4.5-7.0 mm. Body coloration varies from brownish-yellow to brown or brownish gray.
Head: Antennal flagellomeres oval with apical pedicel.
Wing: Elongate, medium-wide, unpatterned, without macrotrichiae in cells. Vein Sc long, Sc 1 reaching at least middle of Rs, Sc 2 at tip of Sc 1. Radial sector medium-long, arched at base. Free tip of R 1 short, R 2 transverse, slightly beyond tip of R 1. Discal cell closed. Basal deflection of CuA 1 close to base of discal cell. Anal lobe widely rounded.
Genitalia: Male genitalia approximately as wide as remaining abdominal segments. Ninth tergite wider than longer. Gonocoxite with simple or bifid ventro-mesal lobe. One pair of gonostyles. Gonostylus often divided

into two or three lobes. Rostral prolongation long, slen- der, arched and spineless. Penis wide, shallowly bifid at tip. Ovipositor with distinctly arched cercus and straight, long, basally blackened hypovalva.
Larvae and Pupae: Described only for A. (M.) machidai ( Alexander, 1921) ( Krivosheina, 2010) . Larval body yellowish, densely covered with long, up to one-fifth to one-fourth of segment’s length, setae. Abdominal segments II-VII with ventral creeping welts. Spiracular field surrounded by five lobes covered with dark sclerites. Spiracles irregularly oval. Head hemicephalic, heavily sclerotised. Frons less sclerotised than the rest of head, short, widened anteriorly and narrowed posteriorly, anterior part with sensory structures, fused with clypeus. Distinct border between frontoclypeus and labrum absent. Antenna long, three times as long as wide. Mandible heavily sclerotised with three apical teeth, that are different in length. Maxillae consisting of well-developed cardo, stipes, and galea. Labium formed by short plate bounded by rods and bearing group of sensilla on anterior part and long thickened setae over entire surface. Hypopharynx with numerous sclerotised ctenoid plates. Hypostomal plate with five large obtuse teeth.
Pupa unknown.
Bionomics: Larvae develop in rotten logs within wet fibers of the bast of deciduous and coniferous trees.
Distribution: Five extant species belong to this subgenus and are only known from the East Palearctic; A. (M.) inelegans (Alexander, 1924) reaches as far south as Taiwan, and A. (M.) machidai ( Alexander, 1921) is common throughout the Europe ( Oosterbroek, 2017).
