Protopolybia minutissima ( Spinola, 1851) View in CoL
Material examined. ECUADOR: Sucumbios, 6♀, Limoncocha , 06.vii.1971 (M. Naumann) ; BRAZIL: Amazonas, 1♂, 13♀, Presidente Figueiredo , vii.2013 (A. Somavilla) ( INPA) , Acre, 1♀, Rio Branco , 04.x.1998 (S. Mateus) (UNESP- IBILCE).
Distribution. Surinam; French Guiana; Ecuador (Napo), Peru (Junín), Brazil (Amazonas, Mato Grosso, Pará, Rondônia, Acre), Mexico.
Remarks. The last revision of the group included only new collection records and annotations about its distribution. According to Santos-Junior et al. (2015), P. minutissima is similar to P. similis , particularly with regard to the width of the clypeus and shape of the occipital carina, which extends to the insertion of the mandible. The male and its genitalia are here described, and the cited revision provides additional traits for the identification of P. minutissima .
MALE (hitherto unknown). Length of fore wing 4.2 mm; eyes wide, strongly produced inwards; clypeus very narrow, with elongate silvery bristles ( Fig. 9 View FIGURES 9 – 14 ); ventral margin narrowly curverd; tentorial pit closer to eye margin than to antennal socket; gena very narrow ( Fig. 10 View FIGURES 9 – 14 ); mandibles black; color like female. Parameral spine without elongate bristles; basal and apical angles of paramere widened ( Fig. 11 View FIGURES 9 – 14 ); digitus narrow with apical margin approximately rounded and with sparse bristles; basal process not acuminate ( Fig. 14 View FIGURES 9 – 14 ); cuspis with few and sparse bristles; ventral process of aedeagus not laterally projecting ( Figs 12, 13 View FIGURES 9 – 14 ), strongly sclerotized and weakly serrated; preapical region of aedeagus not angular in lateral view.
Regarding the apex of the aedeagus, its shape is sharply expanded laterally, forming two lobes in common with other species of the P. exigua species-group, such as P. bituberculata , P. diligens and P. clypeata ( Santos-Junior et al. 2015) . Furthermore, a dorsal view of the aedeagus also revealed a median emargination, a trait that seems to be a synapomorphy of the genus, although this is less developed in P. holoxantha ( Ducke 1904) and P. bituberculata .
