Figs 21-22. Aedoeagus in dorsal and lateral view: Diastolinus fairmalrei Marcuzzi (21) and D.margaritensis Marcuzzi (22) Diastolinus margaritensis Marcuzzi, 1949 (Fig. 22) MARCUZZI (1949): Méms Soc.Cienc.nat. 'La Salle', 9: 338, 339, 344. Examined specimen: Margarita, El Valle. Very similar to that of D.falrmairei, but basale more developed (A:B = ca.0,40), basale in dorsal view more ovoidal, narrowed posteriorly, apicale more tubular, not so funnel-like as in fairmairei

, with the microsculpture more extended than in the previous species. Parameres on the ventral side more widely separated than in D. curtus and D. fairmairei

. In lateral view rather slender, posteriorly pointed, the apicale also slender, gradually restricted towards the apex, which seems less pointed than in D.falrmairei and D.curtus

. The last three species, South-Caribbean, are very different in the form of the phallus from all the true Antillean species because of the form of the apicale and the presence on the ventral edge of the parameres of a very characteristic microsculpture. This feature, associated to outer (skeletal) morphology points to a possible systematic divergence between South Caribbean and Antillean species (see Comments). Opatrinus gemellatus (Olivier, 1795) (Fig. 23-27) OLIVIER (1795): Entomologie, 3. No. 60: 9, pi. 8, Fig. S (Blaps). Examined specimens: 1) Tacagua, Caracas, D.F. (Fig.

24); 3) Margarita, Salamanca (Fig. 25); 4) St. Lucia (Fig.

26); 5) Grenadines,Mustique Id. (Fig. 27). General aspect of South American and Caribbean Pedinini, very variable. Basale much more developed than apicale (A:B = 0,18-0,37), ovoidal (in a specimen from St.Lucia very wide in the
