* Tmesorrhina laeta burgeoni Allard, 1991

( Figs. 25h, i , 26a )

Distribution: ANG, DOC.

Distribution in Angola (Provinces): 2) CUS.

Historic records: none.

Material examined: Mussende (Calulo) (9º 57´00´´ S, 14º 47´36´´ E, 905m alt., 128) ( CUS), 28.XI.-5.XII.2015, 10♂, 1♀, CT, 30.XI.2015, 1♀, BT, A. Serrano & R. Capela leg., ASC; Calulo (Fazenda Klein) (10º 02´14´´ S, 14º 54´38´´ E, 1059 m alt., 147) ( CUS), 6–11.XII.2017, 7♂, 2♀, CT, A. Serrano & R. Capela leg., ASC; Calulo (Faz. Monte Café) (09º 59´15´´ S, 14º 50´12´´ E, 1086 m alt., 128) ( CUS), 6–11.XII.2017, 5♂, 1♀, CT, A. Serrano & R. Capela leg., ASC .

Remarks. Two subspecies are recognized in T. laeta . Both are known from DOC ( Krajcik 2008a, Beinhundner 2017a). The adult specimens of Calulo ( Figs. 25h, i , 26a ) fit very well the mesosternal process and parameres conformations of this subspecies ( Figs. 7 , 8 in Antoine 2002a). Tmesorrhina laeta burgeoni presents coloration darker than the nominal subspecies. The adult specimens could be ascribed to T. garnieri Allard, 1993 , but the parameres are slightly different. Moreover, Calulo specimens present the elytra almost smooth, not deeply striated punctuated as in the latter species ( Allard 1993). The adult specimens were sampled by means of BT and CT within secondary moist forest. See also the remarks under Chlorocala africana mutica . It is a new species/subspecies record for Angola and the Kwanza Sul Province.
