Key to species of Muisca SPINOLA My efforts in the production of this key strive to use convenient characteristics of external morphology. But, the distinction between closely related species is sometimes small and when possible the reader should in most cases rely in the shape of the phallus for definitive species identifications. 1 Pronotum with secondary tubercle (Fig. 47) (M. insigna- group) ..................................2 1' Pronotum without secondary tubercle ...........................................................................3 2(1) Elytral asetiferous punctures terminate at elytral middle (Fig. 125) (Bolivia, Brazil, Paraguay) ........................................................................
