Abstract

Morphometrical data of pronotum, elytra, and total length of adult males and females of a Gratiana spadicea population from southern Uruguay are given. Descriptions and illustrations of aedeagus and spermatheca are provided for the first time. Females were significatively larger than males in total length. The coefficient of variation of the aedeagus measures ranged from 3.7% to 7.7%, and those of the spermatheca from 4.1% to 11.2%. The best value for the coefficient of determination was obtained for the reciprocal regression (1/Y = a + bX) of the total length of the aedeagus versus the length from the apex to the basal region of the median lobe.Dados morfométricos do pronoto, do elitra e do comprimento total de machos e fêmeas adultos de uma população do sul do Uruguai são apresentados. A primeira descrição e ilustrações do edeago e da espermateca são fornecidos. Em termos de comprimento total, as fêmeas são significativamente maiores do que os machos. O coeficiente de variação das medidas do edeago variou de 3,7% a 7,7%, e o da espermateca, de 4,1% a 11,2%. O melhor valor para o coeficiente de determinação foi obtido para a regressão recíproca (1/Y = a + bX) do comprimento total do edeago versus o comprimento do apex à região basal do lobo mediano.
