Mycetophila uninotata Zetterstedt, 1852

Male terminalia. Posterior margin of gonocoxite with shallow convexity ventromedially, and with blunt and oblique projections laterally. Posterior impression very wide and compressed, with emarginated anterior margin. Anterior impression with anteriorly evenly divergent narrow arms. Ventral branch of gonostylus with asymmetrical, narrow and elongated posterior process with dense and long warts; spine 1 sharply pointed; spine 2 about the same size, pointed; spines 3 and 4 smaller, pointed, closer to each other than to spine 2. Dorsal branch of gonostylus steeply tapering; lateral margin with shallow concavity; distal posterior process and proximal posterior process about the same height, both separated by a deep notch. Distal posterior process with 1–2 apical small setae and one bigger subapical seta; proximal posterior process bare and angular. Posterior margin proximally from medial bristle with 3-4 bigger gradually diminishing bristles followed by 2–3 smaller setae; internal surface with a stronger seta next to the medial bristle. Basal angle almost right-angled; basal margin with few setae. Ejaculatory apodeme with campanulate base and without rim. Aedeagus mostly triangular-shaped, apically widened. Aedeagal guides: 1) with two lamellae, 2) with wide and shallow lateral impressions, and 3) apically rounded, not extending beyond aedeagus distally. Aedeagal apodemes laterally angular.

Intraspecific variation. The wide and compressed posterior impression of the gonocoxite, the distinct warts on the posterior process of the ventral branch of gonostylus and almost equal posterior processes of the dorsal branch of the gonostylus allow the species to be safely distinguished. In Finnish material, spine 2 on the ventral branch of the gonostylus is more massive than described by Laštovka (1972). In some specimens the base of the ejaculatory apodeme and the lateral margin of the dorsal branch of the gonostylus resemble those of M. ichneumonea. Phylogenetic analysis based on molecular data revealed three different clades that cannot be distinguished based on morphology
