A new Lobosceliana Dirsh species (Orthoptera: Pamphagidae: Porthetinae) from coastal Tanzania, East Africa.
A new flightless species of Lobosceliana is described from coastal Tanzania, East Africa. This is the first species within this genus with shortened wings in the male sex. The antennal formula is special in this species as well since it differs from that of other Lobosceliana species, questioning the systematic value of the number of antennal segments in Porthetinae as a useful generic character.

متن کاملPebble nest microhabitats of Semotilus species (Pisces: Cyprinidae)
The pebble nest microhabitats of four species of Semotilus were compared. Pit/mound nests of Semotilus corporalis were significantly larger than the pit/ridge nests of Semotilus atromaculatus, Semotilus lumbee, and Semotilus thoreauianus. Nests of S. corporalis were in wider and deeper streams. Pits of S. lumbee nests were longest of the four species; those of S. corporalis were widest and deep...
متن کاملA new species of redfin (Teleostei, Cyprinidae, Pseudobarbus) from the Verlorenvlei River system, South Africa
Pseudobarbusverloreni, a new species, is described from material collected in the Verlorenvlei River system on the west coast of South Africa. It differs from its congeners (except Pseudobarbusskeltoni, Pseudobarbusburchelli, and Pseudobarbusburgi) by the presence of two pairs of oral barbels. Pseudobarbusverloreni sp. n. can be distinguished from the three currently described double barbeled P...
