Remarks. Spinola’s name Polistes minutissima seems to be the oldest name applicable to a species of the genus, and problems related to the probable loss of the type, and to difficulty of diagnosing close very similar species led to its use in several combinations referring to supposed varieties or subspecies (Bequaert 1944a; Richards 1978). Recently, Carpenter (2012) examined type of de Saussure’s species deposited in the Spinola Collection in Turin, and solved various problems concerning the proper understanding of the concept of Protopolybia minutissima (Spinola) and relations with Polybia laboriosa de Saussure and Polybia minutissima de Saussure, and Protopolybia rugulosa Ducke. In particular, and very importantly, synonymy of Protopolybia laboriosa (de Saussure) under P. minutissima (Spinola) implies that the distribution of Protopolybia minutissima is now extended a thousand kilometers to north, up to Mexico (the only reference regarding the type locality of laboriosa).
