Type species: Promanus depressus Sharp, 1877
Remarks. The type species was described in detail and illustrated by Kolibáč (2005) and its morphological characters were listed repeatedly by Kolibáč (2006). A phylogenetic position and classification within the tribe Lophocaterini were also mentioned in the latter paper and Kolibáč (2008).
Two other species of Promanus, P. auripilis Broun, 1893 and P. subcostatus Broun, 1909, were studied preparing this communication. Generally, they are very similar to P. depressus, therefore, the genus is rather morphologically homogenous. Differences among all three species are listed in Table 2. P. auripilis and P. costatus are similar each other. There are no significant differences in their sternites and tergites VIII (Figs 10, 11, 14, 15, 18, 19) as well as in ovipositors and membranous parts of female reproductory organs (Figs 12, 13, 16). Morphological differences mentioned in Table 2 are distinct but only single specimen of the each species was for study at disposal. That is not excluded that outer morphological characters, i.e. the elytral carinae, shape of mesosternal anterior margin, sculpture of head, body colour and body size, are variable in fact. The larger series of Promanus specimens should be studied to resolve the status of the both mentioned species. P. depressus differs distinctly from them, especially in body colour which is brown-black in all three studied specimens.
