, are very similar and distinctive externally, both being relatively elongate (Fig. 98D), having a complete outer subhumeral stria, and a propygidium with fine dense punctures on either side of a more coarsely punctate central area (Fig. 98E). This type of propygidum can be found in a few other species, but these species are larger and more distinctly parallel-sided than any others. Their genitalia (Fig. 99) are remarkably different given their external similarity, but they do share a few important characters, and appear to be related: they lack accessory sclerites at the base of T8; apices of T9 are widened and appearing obliquely truncate; the inner edges of T10 are desclerotized and separate; apex of S9 emarginate, with separate apical flanges; median lobe relatively short, but with a large gonopore and elongate basal apodemes with strongly sclerotized basal stems.
