Lindner (1935) described the genus Hypoceromys and pointed out the similarity to Psapharomys Grünberg. But because of the more dorsally inserted arista-like last antennal flagellomere, he proposed this new genus. He was not aware of the strong sexual dimorphism in this genus (and in the related Psapharomys, see below). When he described Meristomeringella jamesi (Fig. 5), he compared the new genus with Meristomerinx Enderlein, which is strange because the two genera are not really similar, especially vein R2+3 arising distinctly distal to crossvein r–m in Meristomerinx and proximal to crossvein r–m in Meristomeringella . Only a year later he described Hypoxycera simplex and mentioned that the last antennal flagellomere was inserted slightly dorsad on the spindle shaped flagellum, which is also the case in Meristomeringella jamesi . We examined the type specimens of both species and concluded that they are conspecific, and that they belong in the genus Hypoceromys .

The holotype of Pachygaster nigripes (Fig. 6) has the antennae missing (as mentioned in the original description), but all other characters, such as the wing venation, shape of the head and body shape clearly place this species in the genus Hypoceromys .
