Euceroptres maritimus Weld, 1926

Diagnosis. Females readily distinguished by having 10 flagellomeres (all other species with either 11 or 12). Separated from E. primus and E. whartoni by the presence of well-developed micropores on the metasoma (cf. MP, Fig. 1F); this trait is also shared with E. montanus. Males and females have dense felt-like setae present in the mesopleural triangle, the setal pits of the metapleuron and between the propodeal carinae; all other species have setae in these areas, but they are not dense and felt-like.
Redescription. Female. As in description of genus, with antennae of female 12 segmented (10 flagellomeres); median mesoscutal impression deep, short, notch-like (Fig. 2B); mesoscutum distinctly transversely rugulose across entire surface; dorsal-anterior margin of mesoplueron umbilicate-rugulose, transitioning to rugulose ventrally; mesopleural triangle with dense, felt-like setae; metapleuron evenly covered with long setae except episternal area posterior to anterior impression of metepisternum, smooth, glabrous; felt-like setae in ventral setal pit; metasomal T4–T9 with distinctly visible micropores (cf. Fig. 1F), dense setal band present along posterior margin of T8; metafemora orange; metatibia medially orange, laterally dark brown; pro- and mesotarsomeres dark orange to brown; metatarsomeres dark brown or black.
Male. As in female but with 13 flagellomeres; flagellomere 1 as long as fourth antennal segment, laterally excavated, expanded slightly on distal end.
