http://lsid.speciesfile.org/urn:lsid: Orthoptera .speciesfile.org:TaxonName:180009

Holotype male, Tanzania, Kisarawe District, coast region near Dar es Salaam, Kazimzumbwi forest reserve, January/ February 1991, leg. FRONTIER Tanzania. Depository: ZMUC.

The holotype is unique.

Description.—Male. General habitus and colour as other Afrophisis species. Body medium sized, comparatively robust. Head and antennae.— Fastigium verticis short, conical, much shorter than scapus. Antennae very long and thin, 6 cm. Thorax.— Pronotum with pair of reddish-brown fasciae; median transverse sulci well developed. Anterior margin of pronotum slightly concave, posterior margin slightly rounded. All three pronotal sterna armed; prosternum with pair of laterally compressed processes that are more slender and longer than the rather short and blunt processes of meso- and metasternum. Tegmina and wings well developed, surpassing apex a few mm. Stridulatory area of male as in Fig. 15 J. Legs.— Fore coxa with spine. Fore legs with 5 inner and 4 outer long predatory spines on femur and 7 inner and 7 outer on tibia, mid femora with three outer spines and 3 shorter ones on inner side. Hind femora with numerous small spines along distal part of ventral femur. Hind tibiae with 4 rows of numerous small spines along whole length. Last abdominal tergite differentiated into two broad lateral lobes ending at both sides in blunt and short process ( Fig. 15 K, L); between processes posterior margin evenly rounded. Cerci slender and slightly inwardly curved. Subgenital plate broad with posterior margin almost circlic incised with slender styli ( Fig. 15 L).

Female.—Unknown.

Measurements, male (mm) (N = 1). Body length 13.7. Length of pronotum 3.5. Length of elytra 13. Length of hind femur 12.

Diagnosis.— A. kisarawe n. sp. has an unmodified supra-anal plate and slender, slightly incurved cerci. All other Tanzanian species have strongly modified supra-anal plates and thickend, worm-like cerci. From West African species differentiated in wearing a fore coxal spine, absent in all West African species but present in all East African species.

Distribution: Only known from the type locality in Tanzania, near Dar es Salaam.

Habitat: Coastal forest.

Remarks: The specimen of A. kisarawe n. sp. was found in the spirit collection of the zoological museum of Copenhagen. The material was collected by the project FRONTIER in 1991. Further Orthoptera species collected in the Kazimzumbwi forest reserve were Cymatomerella muta Beier , Aerotegmina megaloptera n. sp., Parapyrrhicia zanzibarica Brunner von Wattenwyl, Gonatoxia maculata Karsch , Poecilogramma striatifemur Karsch , Horatosphaga magna Ragge , Ducetia biramosa (Karsch) , Eulioptera monticola Ragge , Ectomoptera sp. and Dioncomena ornata Brunner von Wattenwyl.
