Abstract

A discussion is presented about specimens that are morphologically intermediate between Nephrotoma ferruginea (Fab.) and N. suturalis suturalis (Loew). The specimens came from far outside the present ranges of these two species, namely Kerrville, Texas. It is concluded that the specimens might represent a population of hybrids. It is further estimated that the withdrawal of the parental species from central Texas could possibly have occurred a thousand years ago or earlier.

Résumé

Il s’agit d’une discussion concernant des spécimens morphologiquement intermédiaires entre Nephrotoma ferruginea (Fab.) et N. suturalis suturalis (Loew). La provenance de ces spécimens, Kerrville au Texas, est bien en dehors des limites connues présentement de ces deux espèces. On conclut que ces spécimens pourraient représenter une population d’hydrides. On estime de plus que la disparition des espèces parentales du centre du Texas pourrait avoir eu lieu il y a mille ans ou plus.
