Description. Male. Mix of green and brown colours, abdomen and fastigium verticis in some males black. Colour pattern similar to P. melanocercus n. sp. but abdomen and cerci not as deep black but of more dark brown colour. Abdomen. Space between processes of 10th abdominal tergite rhombic (Fig. 15 G). Inner branch of male cerci inflated and slightly compressed. Tip very narrow again and acute (Fig. 15 H).

Female. Ovipositor typical for Phlesirtes, as long as body length. Subgenital plate as in Fig. 5 L.

Measurements male (mm) (N=2). Length of body 10–10.5, length of pronotum 4.7–5.0, length of anterior femur 2.4–2.5, length of posterior femur 9.3–9.4, visible part of elytra from above 1.4–1.8.

Measurements female (mm) (N=1). Length of body 11.5, length of pronotum 3.9, length of anterior femur 2.5, length of posterior femur 10.2, ovipositor 11.5.

Diagnosis. Rhombic shaped gaps between the processes of the 10th abdominal tergite are also found with P. nou n. sp., P. kilimontanus n. sp. and P. laikipiaensis n. sp. None of the above listed species with rhombic gaps between the processes of the 10th abdominal tergite has an inner branch of the male cerci which is inflated though. An inflated but laterally compressed inner branch of the male cerci is also present in P. latifrons . In P. ngorongoroensis n. sp. the inner branch of the male cerci is not as strongly laterally compressed as in P. latifrons . The tip of the inner cercal branch is also very thin and acute in P. ngorongoroensis n. sp. while it is stouter in P. latifrons .

Habitat and distribution. Tanzania, Ngorongoro conservation area. Montane grasslands 2200–2400 m.
