| Description: | Two new species of Neotropical aquatic beetles, Crenitulus namasus sp. n. from the Apurense plain and C. merida sp. n. from the Andes, both taxa collected manually. Crenitulus namasus sp. n. is characterized by a minute diameter, while C. merida sp. n. It was characterized by its robustness. The main characteristic of the genus Crenitulus Winter, 1926 is evidenced in the corporeal shape, which is wide in the humeral margin and attenuated towards the apex, the antennae with nine antennomeres and the parameres pointed or attenuated towards the apex, in addition to presenting convexity in its outer margin. A review of the species deposited in the Museum of Arthropods of the University of Zulia, Maracaibo, Zulia, Venezuela is synonymized Crenitulus gamboa Garc铆a, 2016, with C. solstitialis Kirsch, 1873. Habitus, palps, antenna, chin, proventrite, mesoventral process and genital sclerite are illustrated and a list with all recorded Crenitulus species is included. Se describen dos nuevas especies de cole贸pteros acu谩ticos Neotropical, Crenitulus namasus sp. n. del llano apurense y C. merida sp. n. de los andes, ambos taxones recolectados manualmente. Crenitulus namasus sp. n. esta caracterizado por un diminuto di谩metro, mientras que C. merida sp. n. se caracteriz贸 por su robustez. La caracter铆stica principal del g茅nero Crenitulus Winter, 1926 se evidencia en la forma corp贸rea la cual se muestra ancha en el margen humeral y atenuado hacia el 谩pice, las antenas con nueve anten贸meros y los par谩meros aguzados o atenuados hacia el 谩pice, adem谩s de presentar convexidad en su margen externo. Una revisi贸n de las especies depositadas en el Museo de Artr贸podos de La Universidad del Zulia, Maracaibo, Zulia, Venezuela se sinomiza Crenitulus gamboa Garc铆a, 2016, con C. solstitialis Kirsch, 1873. Habitus, palpos, antena, ment贸n, proventrito, proceso mesoventral y esclerito genital son ilustrados y se incluye un listado con todas las especies de Crenitulus registradas. |
