| Popis: | Microphorella Becker Microphorella Becker, 1909: 28. Type species: Microphorus praecox Loew, 1864, by original designation. Diagnosis. Southern Hemisphere Microphorella can be distinguished from other parathalassiines by the following suite of characters (similar to the diagnosis of Australasian Microphorella given in Brooks & Cumming 2022): head with face broad, subequal to wider than combined width of antennal bases, or strongly narrowed ventrally (e.g., males of M. amorimi sp. nov.), gena weakly developed to moderately broad, antenna with arista-like stylus not lengthened (about 3X length of postpedicel or shorter) (Figs 6, 15), mouthparts directed ventrally, palpus narrowly ovate (Fig. 6), subtriangular, or broadly clavate and flattened (Fig. 26); thorax with prosternum fused to proepisternum and forming precoxal bridge, scutellum with 1 pair of strong setae near apex; wing with vein M 2 and cell dm present (Figs 8, 17), vein R 1 reaching costa beyond or (rarely) just before base of M 2, cell cua convex apically, vein CuA + CuP short to absent, anal lobe barely developed; male terminalia with right epandrial lamella lacking ventral process, cerci including hypoproct nearly symmetrical and pointed to highly asymmetrical (Fig. 21); female abdomen with apical segments retractable into segment 5 or 6, syntergite 9+10 divided and bearing acanthophorous setae (Fig. 22) or acanthophorous spines (Fig. 13), cercus relatively broad, with apex pointed or broadly rounded, with or without long apical seta(e). Remarks. Cumming & Brooks (2019) recognized five distinct species groups of Microphorella from the Southern Hemisphere, including the two species, each in their own group, described below from the Neotropical Region (Chile) and the Afrotropical Region (South Africa). The three other species groups occur in Australia and Southeast Asia, including New Guinea (Brooks & Cumming 2022). All four species included in the Microphorella malaysiana species group, which occurs in Southeast Asia and New Guinea, are treated in this paper even though the distribution of some species extends north of the equator. Worldwide the genus is known from various riparian, meadow and coastal habitats (Cumming & Brooks 2019).
