Abstract
At least three species of New Guinean tree frogs (Litoria) are sexually dimorphic in that the snout of the male is projected into a proboscis, which is poorly developed or absent in females. In this paper the anatomy of the proboscis in the male Litoria pronimia is described and compared with the structure of the smaller proboscis of Litoria havina, described previously. We note that it appears to be erectile, speculate on the possible method of erection and suggest directions for future research.
