Afroanthracites uluguruensis Hemp & Ünal

n. sp.

Afroanthracites uluguruensis Hemp & Ünal   n. sp. ( Fig. 7 View FIGURE 7 E–H, Fig. 8 View FIGURE 8 I, J) orthoptera 180003

Holotype, male, Uluguru Mountains. Depository: BMNH. The holotype is unique.

Description.—male. General colour mixed green and brown to black, a large black patch on rear part of prontal disk. Head and antennae.—Fastigium verticis acute conical, only slightly compressed, shorter than scapus. Face uniformly green. Antennae long, more than twice the length of body. Scapus and 2 nd (= pedicellus) antennal segment green, following segments long and thin, of dark colour till approximately segment 5–6, remaining segments pale. Thorax.— Pronotum rugose, rounded, posterior area (in metazona) slightly inflated. Tegmina completely hidden under pronotum. Legs.— Fore femur with 3 inner, mid femur with 3 outer spines. Hind femur with 5 outer short ventral spines. Hind tibia with 4 apical spurs ventrally. Abdomen.— Tenth abdominal tergite at posterior margin incised, forming two broadly rounded lobes ( Fig. 7 View FIGURE 7 F). Subgenital plate elongated, posteriorly upcurved and little incised medially; styli short ( Fig. 7 View FIGURE 7 G, H). Tittilators with narrow acute tip and broad projection ( Fig. 8 View FIGURE 8 J) other details not visible as preparation has not been cleaned.


Measurements, male (mm) (N = 1). Body length 22. Length of pronotum 7.5. Length of hind femur 11.

Diagnosis.— A. uluguruensis   n. sp. is morphologically related to A. montium   and A. usambaricus   with which it shares similar colouration and structure of the male abdominal apex. A. viridis   n. sp. and A. discolor   n. sp. have a morphological completely different 10 th abdominal tergite, being shield-like in A. viridis   n. sp. ( Fig. 7 View FIGURE 7 B) and medially divided into two parts in A. discolor   n. sp. ( Fig. 7 View FIGURE 7 J) while A. uluguruenis   n. sp. has the 10 th abdominal tergite medially incurved so that the posterior margin is divided into two rounded lobes ( Fig. 7 View FIGURE 7 F). A. viridis   n. sp. is vivid green with a conspicuous pronotal colour pattern and a yellow 10 th abdominal tergite ( Fig. 5 View FIGURE 5 , 6 View FIGURE 6 ), while A. discolor   n. sp. has a contrasting pattern of hazelnut brown, cream and green colours ( Fig. 4 View FIGURE 4 ). A montium   has a male 10 th abdominal tergite that is elongate and incised medially at the posterior margin ( Fig. 7 View FIGURE 7 N) but much narrower than in A. uluguruensis   n. sp. which has a broad posterior margin. In A usambaricus   the tenth abdominal tergite is not incised at all but has a narrow and blunt posterior end ( Fig. 7 View FIGURE 7 R). A. jagoi   n. sp. has an elongated, very narrow 10 th tergite with medially incised posterior margin ( Fig. 7 View FIGURE 7 V).
