Taxonomic notes.

Upon close examination of the monobasic genus Pseudomenarus (Shibata, 1964), it became apparent that there were several diagnostic similarities with members of the genus Formosiella Jedlička, 1951. For the genus Formosiella , Jedlička cited defining characteristics as being: tarsomere 4 not bilobed; pronotum wider than head and strongly indented; elytra with three fixed seta in interval 3 and a dorsal surface that is finely and densely ciliated. Shibata’s Pseudomenarus flavomaculatus shares all of these characteristics and externally, also shares a toothed mentum and distinctively acuminate apices of both labial and maxillary palpi (Fig. 50B). Internally, the female genital tract is also very similar to Formosiella brunnea (See Fig. 77A, B) and distinctive from all other pericaline genera. With this in mind, Pseudomenarus is synonymized with the generic name Formosiella .
