Pseudinca fradei ( Gomes Alves, 1973) , new combination

( Figs. 16d, e, f, g, h )

Distribution: ANG.

Distribution in Angola (Provinces): 1) MOX.

Historic records:

—Fazenda Stª Cruz (Luso=Luena) (MOX) ( Gomes Alves 1973 sub Ruteroides fradei Gomes Alves ).

Material examined: Luso (=Luena) (Fazenda Stª Cruz) (11º 46´S, 20º 06´E, 1280 m alt., 219) ( MOX), 24.X.1958, 1 ♂, Nº 3035, Holotypus (red label), Ruteroides fradei Gomes Alves det. 1973, Estudos Apícolas do Ultramar , Junta de Investigações Coloniais, IICT, MUHNAC .

Remarks. An endemic species of Angola whose original description was based on a male specimen, under the genus Ruteroides ( Gomes Alves 1973) . This author referred that the specimen was observed by Ruter, who postulated that probably it should belong to a new genus near Porphyronota . However, we conclude that Ruteroides is similar to Pseudinca (see comments on this genus). Pseudinca fradei new combination is close to Pseudinca rufulus Kolbe, 1914 , Pseudinca variatus Bourgoin, 1921 and Pseudinca striatus Valck Lucassen, 1933 , but can be segregated from them by some morphological characters such as clypeus without longitudinal ridge, the shape of clypeal anterior edge (slightly raised and straight) ( Fig. 16e ), the discal punctuation of pronotum (distinct and sparse) ( Fig. 16e ), the sutural round angle (not acute) of elytra ( Fig. 16d ), the shape of mesosternal apophysis and the punctuation of abdominal segments ( Fig. 16f ), among others. In Beinhundner’s monograph (2017a: 594), the authorship of names Ruteroides and Ruteroides fradei is incorrect (Goméz Alvéz must be spelled as Gomes Alves). Moreover, in the same monograph (p. 594, lines 9 and 13), just before the Gomes Alves (1973) references and after the genus and the species “Description”, the names Myodermidius and Myodermidius rohani are given, respectively. However, both taxa are not mentioned anywhere in Gomes Alves (1973) work. Beinhundner (2017a) indicates Republic Guinea for the distribution of this species, which is incorrect also. Biological and ecological data are not available for this species.
