ABSTRACT
El género Dyscinetus Harold, 1869 (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini) es redescrito y comparado con Chalepides Casey, 1915 (Cyclocephalini). De las seis especies encontradas en Venezuela quatro son redescritas, una es transferida de Chalepides y redescrita y una es nueva: Dyscinetus dytiscoides Arrow, 1911, D. paradytis (Ponchel & Dechambre, 2003) comb. nov., D. dubius (Olivier, 1789), D. rugifrons (Burmeister, 1847) nuevo registro para el país, D. olivaceus Höhne, 1923 y D. mendax sp. nov., esta última de amplia distribución en América del Sur (Bolivia, Brasil, Ecuador, Guayana Francesa, Perú, Trinidad y Surinam) y usualmente confundida con D. olivaceus. Se presentan clave para identificar las especies venezolanas, ilustraciones de los caracteres de diagnóstico, algunos hospedadores y mapas de distribución.

Six species occur in Venezuela, four are redescribed, one is transferred from Chalepides and redescribed, and one is a new species: Dyscinetus dytiscoides Arrow, 1911, D. paradytis (Ponchel & Dechambre, 2003) comb. nov., D. dubius (Olivier, 1789), D. rugifrons (Burmeister, 1847), new country record, D. olivaceus Höhne, 1923 and D. mendax sp. nov., the last one is usually confused with D. olivaceus and is widely distributed in South America (Bolivia, Brazil, Ecuador, French Guiana, Peru, Trinidad and Suriname). Identification key for Venezuelan species, diagnostic illustrations, some host data and maps are included.

ABSTRACT
A study is made of a group of 67 persons with diabetes mellitus, over 15 years of age, in order to know the presence and severity of periodontal disease, in relation with degree of oral hygiene, age, duration of the course and degree of metabolic control of diabetes. It was shown that 85.1% of the cases had some form of the periodontal disease, the most frequent of which being advanced periodontitis (34.3%). 100% of the patients had an inadequate oral hygiene. Lack of metabolic control, age and degree of oral hygiene correlated positively with the severity of periodontal disease.
