However, sometimes dental abnormalities appear that involve changes in the shape and number of teeth which can lead to erroneous taxonomic identifications. Numerous cases of dental anomalies have been reported for all groups of mammals, especially bats, the group with the most dental anomalies reported. This note presents a rare case of bilateral hyperdontia in Carollia brevicauda, for which only cases of oligodontia had previously been registered. The dental anomaly was found in a male specimen of silky shorttailed bat from the middle basin Rio Guayuriba, Acacias, Meta, Colombia. The unusual individual shows an additional incisor annexed to each normal external incisor in the maxilla, with separate alveoli, for a total of 6 upper incisors, two more than normal. The extra teeth have a morphology similar to the external incisors characteristic of the species, short and rounded, and are located between the canine and the second (external) upper incisor on each side of the head. No other specimen among 66 individuals of the same species showed a dental anomaly. This is the first record of bilateral hyperdontia for C. brevicauda. This dental anomaly may be due to an isolated mutation in this individual, because no other specimens with this type of anomaly were found in the study area.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen: La sistemática y taxonomía de los murciélagos está basada en parte sobre las características morfológicas de los dientes y sus fórmulas dentales. Sin embargo, a veces se presentan anomalías dentales que involucran cambios en la forma y número de los dientes lo cual puede llevar a identificaciones taxonómicas erróneas. Numerosos casos de anomalías dentales han sido reportados para todos los grupos de mamíferos, especialmente los murciélagos, el grupo con más anomalías dentales reportadas. Esta nota presenta un raro caso de hiperdontia bilateral en Carollia brevicauda, para el cual solamente casos de oligodontia han sido previamente registrados. La anomalía dental fue encontrada en un espécimen macho del murciélago de cola corta desde la cuenca media del Rio Guayuriba, Acacias, Meta, Colombia. El inusual individuo muestra un incisivo adicional anexo a cada incisivo externo normal en la maxila, con alveolos dentarios separados, para un total de seis incisivos superiores, dos más de lo normal. Los dientes extranumerarios tienen una morfología similar a los incisivos externos característicos de la especie, cortos y redondeados, y están localizados entre el canino y el segundo incisivo superior (externo) sobre cada rama maxilar. Ningún otro espécimen entre los 66 individuos de la misma especie mostró una anomalía dental. Este es el primer registro de hiperdontia bilateral para C. brevicauda. Esta anomalía dental puede deberse a una mutación aislada en este individuo, porque ningún otro espécimen con este tipo de anomalía fue encontrado en el área de estudio.]]></p></abstract>
