Remarks. Two subspecies were recognized within D. gagates , the nominal and Diplognatha (Diplognatha) gagates silicea MacLeay, 1838 ( Holm & Marais 1992; Beinhundner 2017a). However, Basilewsky (1956) and Rigout & Allard (1992) considered these subspecies as species (a criterion followed here), stating that they differ by the number of mesotibial teeth (two vs. one) and other minor morphologic pronotal charaters (lateral punctuation and crenulation). These authors, Krajcik (2008a) and Schoolmeesters (2018) considered also that Diplognatha (Diplognatha) gagates holosericea Bainbridge, 1842 is a subspecies within this taxon, but Holm (1990b) synonymized it with Porphyronota cinnamomea (Afzelius, 1817) . All the examined specimens exhibit two mesotibial teeth. Unfortunately, the studied adult specimens of MZUC do not present labels with the indication of the sampling localities. Comparing the available data for both species it seems that Diplognatha (Diplognatha) gagates occurs predominantly in the Northern Provinces of Angola and Diplognatha (Diplognatha) silicea in the central and southern-eastern Provinces. The larva (L 3) was described by Šípek (2005) and ecological data were provided by Holm & Marais (1992).
