PSEUDOMELINA Malloch, 1933: 307 View in CoL

Type-species: Pseudomelina apicalis Malloch, 1933 (monotypic and original designation)

Note: Placement in Sciomyzini is questionable. Marinoni & Mathis (2000) did not address the issue, although they addressed placement of other genera. The original description by Malloch (1933) states, “Agrees in many characters with Melina [= Eutrichomelina ] albibasi s, but lacks the propleural [proepisternal] bristle,” a diagnostic character of all species of Sciomyzini except Atrichomelina pubera , in which the propleural seta is greatly reduced. Knutson (1977: 597) compared 5♀ from Aysén, Linares, and Valdivia ( CNC, USNM) with the holotype and noted, “The propleural bristle [of the holotype] is absent on either side, and there do not appear to be sockets where these bristles may have been present. Five females from the Canadian National Collection ( CNC) compare exactly with the holotype and the description except that the CNC specimens each have a well-developed propleural bristle on each side. The species was adequately described by Malloch (1933). However, in the specimens from the CNC the number of pre-apical anterodorsal bristles on the hind femur, stated as two by Malloch, range from one to three.”
