 en RESEARCH NOTE - The usefulness of bergmann's rule for the distinction of members of Lutzomyia intermedia species complex (Diptera, Psychodidae, Phlebotominae)
Carlos Brisola Marcondes; Ana Leuch Lozovei; Eunice AB Galati & Helena H Taniguchi

Abstract

Bergmann's rule says that homeotherm animals from higher altitudes and
latitudes, or bred at lower temperatures, tend to be bigger, and the
validity of this rule to most studied ectotherms was noted by D Atkinson,
(1994). R.P. Lane made preliminary observations on the effect of 
temperature on the size of Lutzomyia longipalpis and CB Marcondes 
(1997) observed that altitude and latitude also modify several
dimensions of L. intermedia s. s. Moreover, RP Lane and G Fritz
(1986) observed that females of Phlebotomus papatasi are bigger 
than P. bergeroti females. However, the former occurs in lower 
altitudes than the other one, and they concluded that this apparent 
discordance from Bergmann's rule corroborates the distinction of these 
species.
