Erythmelus Enock 1909

ERYTHMELUS Enock, 1909 (Figs 130–135) Erythmelus Enock, 1909: 454. Type species: Erythmelus goochi Enock, 1909, by monotypy. Eurythmelus Ogloblin, 1934: 243 (lapsus). See Huber et al. (2020) for generic synonyms and their type species. Diagnosis. Head in lateral view with gena short (Fig. 135), almost absent, so head often appearing thin; face with toruli distinctly triangular (Fig. 130a); mandibles in both sexes reduced to small stubs, without teeth (Fig. 130a) and maxillae lengthened (Fig. 130b), presumably replacing the mandibles in function; antenna with 6 funicle segments (Fig. 131), rarely only 5; metanotum with dorsellum triangular (Fig. 133) and slightly overhanging propodeum (Fig. 135); propodeum medially with longitudinal sulcus (Fig. 133); gaster in lateral view with hypopygium long, extending posteriorly at least to apex of gaster (Fig. 135). Remarks. Erythmelus belongs to the Anaphes group of genera, a rather poorly defined group (Lin et al. 2007) of two genera. The propodeum has a median sulcus in both genera. Other features, e.g., the greatly reduced mandibles, suggest perhaps a closer relationship to some taxa in the Anagrus group of genera. Neotropical hosts. Hemiptera: Miridae, Tingidae.
