[Entomology • 2017] Annotated Checklist of Orthoptera from Kazimzumbwi Forest Reserve, Tanzania with the Description of New Species and Discussion of the Biogeographic Patterns of Threatened Species


Aerotegmina megaloptera Hemp, 2014


Abstract

A checklist of Ensifera and Acridomorpha of Kazimzumbwi Forest Reserve, Kisarawe near Dar es Salaam is given and eight new Tettigoniidae species described. These are the Agraeciini species Afroagraecia kisarawe n. sp., the Meconematinae species Phlugidia kisarawe n. sp., and the female of Aerotegmina megaloptera (Hexacentrinae). The Phaneropterinae species Dioncomena scutellata n. sp. is known at present only from two localities, the Pugu Hills near Dar es Salaam and Kwamgumi forest reseve on the foothills of the East Usambara Mountains. Two new Eurycorypha species, E. annexata n. sp. and E. ligata n. sp. are described from the area known at present only from the male sex. A second species is described in the genus Lunidia Hemp, L. acuticercata n. sp. Two new Phaneropterinae genera are erected on Pseudopreussia flavifolia n. gen. n. sp. and Materuana ericki n. gen. n. sp., species of wet lowland forest along coastal Tanzania and forest reserves in the East Usambara and on the foothills of the Uluguru Mountains.
Kazimzumbwi Forest Reserve is severly threatened by encroachment and deforestation although it is recognized as belonging to the oldest surviving forests of the world.

Abstract
A list of the Tettigoniidae (Orthoptera) of the East Usambara Mountains is presented and 16 new species are described from East Africa. A total number of 29 Tettigoniidae species is recorded for the East Usambara Mountains. New species are described from the Shimba Hills in Kenya, coastal Tanzania from the Kazimzumbwi forest reserve, Mt Kilimanjaro, the East and West Usambara and Uluguru Mountains in Tanzania, namely in Conocephalinae Afroagraecia pwania n. sp., Afroagraecia shimbaensis n. sp., Afroanthracites discolor n. sp., Afroanthracites jagoi n. sp. and Afroanthracites viridis n. sp., in Meconematinae Afrophisis flagellata n. sp., Afrophisis kisarawe n. sp., Afrophisis mazumbaiensis n. sp. and Afrophisis pseudoflagellata n. sp., in Hexacentrinae Aerotegmina megaloptera n. sp., in Mecopodinae Apteroscirtus cristatus n. sp., and A. planidorsatus n. sp., in Phaneropterinae Gelotopoia amabilis n. sp., and in Pseudophyllinae Cymatomerella pardopunctata n. sp. and Cymatomera viridimaculata n. sp. Seven species are endemic to the East Usambara Mountains which are 25% of the recorded forest-bound bush crickets. The Tettigoniidae fauna is compared between the East Usambara Mountains and Mt Kilimanjaro and mechanisms of speciation discussed in Orthoptera for the area. New Tettigoniidae records are given for Mt Kilimanjaro (Oxyecous apertus Ragge, Tropidonotacris grandis Ragge and Eurycorypha conclusa Hemp).
