Three new Neotropical genera of Nasutitermilinae, of the group with mandibulate soldiers, are described. Cyrilliotermes, gen. n., is related to Curvitermes and inc/udes C. cupim, sp. n. (type species), C. jaci, sp. n., C. cashassa, sp. n., C. strictinasus (Mathews, 1977), comb. n., and C. angulariceps (Mathews, 1977), comb. n., both C. strictinasus and C. angulariceps being removed from Curvitermes. Alates and soldiers are described for C. cupim, Irom Brazil, and for C. cachassa , from Suriname, and soldiers lor C. jaci, Irom Suriname; a new locality is reported for C. strictinasus . Embiratermes, gen. n ., is relaled lo Armitermes and inc/ude E.

ABSTRACT. The morphology of the mandibles of the alates and workers of theThe mandibular morphology is highly adaptive to the soil diet, in a similar way either in the soil-feeding nasutes as in other soil-feeding termites. The function of the molar tooth in the soil-feeding termites is discussed, and new characteristics of the molar regions are presented.

The Greig cephalopolysyndactyly syndrome in characterized by a set of craniofacial defects (macrocephaly, broad nasal root) leading to peculiar facial appearance, postaxial (occasionally preaxial) polydactyly of hands, preaxial (rarely postaxial) polydactyly of feet, and syndactyly of fingers and toes. Occasionally other skeletal or nonskeletal defects are present. This is an autosomal dominant trait with complete penetrance and variable expressivity. Prognosis for mental and physical development of the affected patients is good, surgery being indicated primarily for aesthetic and functional correction of polydactyly and syndactyly. We report on a Brazilian family in whom the mother and two of three sons were affected.
