The genus Dendrobia n. gen. is erected to include D. amaniensis n. sp. from the East Usambara Mountains as type species. A second species in this genus, D. octopuncata n. sp., is described from the Udzungwa Mountains of Tanzania. Dendrobia n. gen. is a canopy dweller found only high up on trees in closed submontane and montane forest. The peak frequency of its song is lower than in all other known African Agraeciini, correlating with the large resonant areas in the tegmina. Two new Afroanthracites species, A. ngologolo n. sp. and A. nguru n. sp. are described from the Eastern Arc Mountains in Tanzania. These species are dwellers of understory vegetation in closed forest in the Udzungwa and Nguru Mountains respectively.

The genus Ectadia is an East Asian genus of the tribe Elimaeini (Phaneropterinae) and is known for the complex stridulatory files of its members. The calling song was so far known from only one species, the relatively widespread Ectadia fulva. Here a new species from Yunnan, China, is described, which is morphologically similar to E. fulva except for the stridulatory file. In this character E. fulva deviates strongly from the new species and from all other Ectadia species by its high tooth number. The long lasting song (duration 30 to 60 seconds at 25°C) of the new species is very complex and differs widely from the much shorter song of E. fulva. Its spectral composition changes during stridulation. In the new species the females respond acoustically during gaps in the final part of the male song, whereas in E. fulva they answer typically after the male song. During mating Ectadia fulva males transfer small spermatophores without spermatophylax. All of its six nymphal stages are cryptically colored. In karyotype the new species being the first studied Ectadia species is similar to the related genera Elimaea and Ducetia (all 2n=29 chromosomes in the male).
