Abstract in English:

Refuse from sugar and alcohol industries is rich in organic matter, offering an ideal breeding ground for house-flies. This pest breeds in countless numbers in such substrate, causing severe outbreaks in several counties of the State of São Paulo, Brazil. To control the nuisance, the formula: borax (Na2B4O7) and slaked lime (Ca(OH)2) solutions of 3.18% and 0.35%, respectively, were applied at the channels carrying the waste waters from the alcohol refinery at intervals of 10-15 days. With this method, a very satisfactory control of house-fly populations was obtained at Macatuba, São Paulo, Brazil, between July 1981 and April 1982.

Abstract in English:

Three new Neotropical genera of Nasutitermitinae, of the group with mandibulate soldiers, are described. Cyrilliotermes, gen. n., is related to Curvitermes and includes 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, from Brazil, and for C. cachassa, from Suriname, and soldiers for C. jaci, from Suriname; a new locality is reported for C. strictinasus. Embiratermes, gen. n., is related to Armitermes and include E. festivellus (Silvestri, 1901), comb. n. (type species), E. benjamini (Snyder, 1926), comb, n., E. brevinasus (Emerson & Banks, 1957), comb, n., E. chagresi (Snyder, 1925), comb, n., E. heterotypus Silvestri, 1901), comb, n., E. latidens (Emerson & Banks, 1957), comb, n., E. neotenicus (Holmgren, 1906), comb, n., E. silvestrii (Emerson, 1949), comb, n., E. snyderi (Emerson & Banks, 1957), comb, n., E. spissus (Emerson & Banks, 1957), comb, n., and E. transandinus (Araujo, 1977), comb, n., all removed from Armitermes. The creation of Embiratermes, besides being based on morphological characteristics of soldiers, workers and alates, is justified by the defensive behaviour of the soldiers, which is different from that of Armitermes soldiers. Ibitermes, gen. n., which seems to be related to Embiratermes, includes only I. curupira, sp. n., described from a series of soldiers and workers from Brazil. Keys based on the soldier caste are provided for the identification of the 11 genera with mandibulate soldiers of the Nasutitermitinae, and for the species of Rhynchotermes, Curvitermes and Cyrilliotermes. Curvitermes planioculus Mathews, 1977 is considered a junior synonym of C. minor (Silvestri, 1901), syn.n.

Abstract in English:

The monotypic genus Elipesurus of neotropical freshwater stingrays, and its type species E. spinicauda, are known from a single specimen which lacked a developed tail and caudal sting. No type or similar specimens exist. The original description and illustration are inaccurate, without diagnostic measurements or characters, excepting those mentioned above. Therefore, a precise identification of E. spinicauda remains impòssible, and both names are considered doubtful. Since all other potamotrygonid stingrays have more or less developed tails and stings, the Elipesurus condition is regarded as a mutilation.

Abstract in English:

Crossodactylus bokermanni, sp. n., is described from Serra do Cipó, Minas Gerais, Southeastern Brasil. The new species is characterized by the small size (20-27 mm), slender build, long legs, narrow head, long and acuminate snout, rounded but fairly defined canthus rostralis, and small tympanum. Also, notes on its habits are made and its tadpole is described.
