Resumen:
The species Apedilum elachistus Townes is recorded in Argentina for the first time representing the southernmost record of this species. Due to dissimilarities found between southern and northern specimens of this species a Principal Component Analysis and Minimum Spanning Tree were performed in order to determine if such differences reflected a geographic pattern. The results show remarkable North-South geographic variation in the number of acrostichal setae, number of dorsocentral setae, number of prealar setae, wing length, VR, length of thorax, and length of abdomen for males, and number of gonocoxite IX setae, length of thorax, number of temporal setae, length of palpomere III, wing length, BV2, length of notum, BV1, number of dorsocentral setae, length of palpomere IV, length of abdomen, VR, and length of palpomere V for females. Consequently Apedilum elachistus from southern South America (Neotropical region) is redefined as larva, pupa, and male and female imago.
