( Figs. 30 , 31 , 32 A, C, E ; 34 B )

Holotype: m ale. Tanzania, Jozani Forest Reserve , Zanzibar, lowland forest, June 2017 . Paratype female, same data as holotype. Depository: collection C. Hemp .

Description. Male. General habitus and coloration. Uniformly to creamy brown, with dark conspicuous black median fascia from head over disc of pronotum; face with black triangle as typical for most other species of Afroagraecia ( Fig. 31 B , female); tegmina with numerous dark dots and small patches (as in female see Fig. 30 ). Head and antennae. Fastigium verticis black, laterally compressed, shorter than scapus, tip acute. Cuticle of head smooth, shining, with few wrinkles. Ocellus small, of lighter colour. Antennae more than twice the length of body, thin, creamy with dark irregular markings along length. Thorax. Pronotum with deep black median fascia, somewhat constricted on mesozona and then widening on metazona ( Fig. 31 A ). Anterior margin of pronotum rounded, posterior margin truncate; metazona slightly elevated. Lateral lobes of pronotum rounded, at height of metazona margin incurved. Prosternum bispinose with tiny spines; meso- and metasterna unarmed. Tegmina and wings slightly longer than body length. Tegmina with numerous dark spots on creamy brown background. Legs. Fore coxa with welldeveloped spine. Spination of femora variable, different numbers of spines were counted on the holotype between each pair of legs. Fore femora 4–5 outer and 1–2 on inner ventral side. Mid femora with 3 outer ventral spines and unarmed on inner side. Hind femora with 6 outer and no inner ventral spines. Abdomen. Tenth abdominal tergite shield-like, posterior margin medially slightly incurved, cuticle shiny. Supra-anal plate finger-like elongated, sulcate ( Fig. 32 A, E ). Male cerci differentiated into a inner shield-like expanded part ending in an almost curling band-like process ( Fig. 32 E ) and an outer branch. The outer branch is divided into two branches that end with acute tips ( Fig. 32 A, B, C ). Subgenital plate with posterior margin v-shaped incurved and with two short styli.

Female. General coloration as in Figs. 30–31 and similar to male. Slightly larger than male. Ovipositor long, slender and slightly up-curved ( Fig. 30 ). Subgenital plate narrow elongated, in anterior part 2/3 sulcate ( Fig. 34 B ).

Measurements, female (mm) (N = 1). Body length 27. Length of pronotum 6.5. Length of elytra 21.6. Length of hind femur 14.6. Ovipositor length 15.3.
