Allen, G. R. and S. J. Renyaan: Three new species of rainbowfishes (Melanotaeniidae) from the Triton Lakes, Irian Jaya, New Guinea, pp. 13-24.

Abstract

Theree new melanotaeniid fishes are described from the Triton Lakes area of western Irian Jaya, Indonesia. They are closely related to one another and apparently evolved from an ancestor of the wide-ranging Melanotaenia goldiei. Melanotaenia kamaka n. sp. is described from 29 specimens, 38.5-60.5 mm SL, collected at Lake Kamakawaiar, and M. lakamora n. sp. is described on the basis of 75 specimens, 25.5-54.9 mm SL, from nearby Lake Lakamora and Lake Aiwaso. They differ primarily in colour pattern, but also in modal number of anal fin rays and the length of the poster rays of males (those of M. lakamora are more elongate). Melanotaenia pierucciae, the third new species, is described from 13 specimen, 28.9-58.7 mm SL, collected from a small creek near Lake Kamakawaiar. It is similar to M. kamaka and M. lakamora, but differs in colour pattern and proportions. Males are more slender and the species also has a more slender caudal peduncle, and shorter dorsal rays in the second dorsal fin. It further differs from M. kamaka in having a shorter caudal peduncle and shorter anal rays.

Andreone, F.: Another new green treefrog, Boophis anjanaharibeensis n. sp. (Ranidae: Rhacophorinae), from northeastern Madagascar, pp. 25-32.

Abstract

In the course of a series of herpetological surveys in Madagascar a new arboreal frog belongin to the “green Boophisi group” (family raidae, subfamily Rhacophorinae) has been discovered. Boophis anjanaharibeensis n. sp. was found in the mid-altitude rainforest of the Anjanaharibe-Sud Special Reserve, in northeastern Madagascar. It is similar ins ome characters to B. luteusi and to B. elenae, from which it differs in the greater development of the head and eyes and in the coloration, dorsally dark green with scattered light spots. The eyes are not red, as in B. l. luteus, but golden with a narrow outer brownish area. The belly is whitish with bluish shadings, as well as digital expansions.
