Holotype male. Tanzania, Bukoba, submontane wet forest, Miziro Forest Reserve, April 2016. Depository MfN. The holotype is unique.
Description. Male. General habitus & colour. Uniformly green, elongate Eurycorypha species. Head and antennae: Scapus green, antennae green, very thin and not surpassing folded tegmina. Fastigium of vertex comparatively narrow, about 2.5 times as wide as scapus of antenna. Fastigium of vertex meeting equally broad fastigium of frons along well developed horizontal line with median sulcus; fastigium of vertex shallowly sulcate when looked at from above; face with strongly callous frontogenal carinae giving face triangular shape. Eyes typical for Eurycorypha, elongate and oval, dark. Thorax: Disc of pronotum slightly depressed, thus lateral margins higher than level of disc, sharp. Anterior margin of pronotum broadly incurved, while posterior margin broadly rounded. Wings: Both pairs of wings fully developed; tegmina very narrow, evenly rounded at tips, about 3.4 times longer as broad. Alae shiny with green area near tips which surpass tegmina when folded. Stridulatory file as in Fig. 25 B, continuous, slightly curved. Legs: Fore coxa with straight rather stout spine. Fore and mid femora on outer side with 3 small spines. Hind femora with 2 inner and 4 outer small spines at distal end. Fore tibiae without dorsal spine. Hind tibiae with four rows of densely set short spines and three apical spurs on each side. Abdomen: Green without any pattern. Last abdominal tergite elongated with apical dorsal bulb and ventral process ending in two short spines (Fig. 25 A). Cerci stout and short, incurved, tips with small sclerotized ridge. Subgenital plate elongate with central keel and two lateral short processes with blunt apices.
Female. Unknown.
Measurements (mm). Male (N = 1). Body length 20.2. Median length of pronotum 4.6. Posterior femur length 12.8. Length of tegmina 27.1. Width of tegmina 8.2.
Etymology. Named after Lake Victoria.
Distribution. At present only known from Miziro Forest near Bukoba but probably more wide-spread around Lake Victoria in suitable forest habitats.
Diagnosis. E. victoriae n. sp. belongs to a group of species characterized by an elongate 10th abdominal tergite which can be beak-like as in E. combretoides and E. elongata n. sp., bi-dentate as in E. meruensis and E. pseudomeruensis n. sp. or differentiated into several dorsal and ventral processes at its apex as in E. divertata n. sp. The shape of the 10th abdominal tergite, however, is uniquely shaped in E. victoriae n. sp. and thus this species may easily distinguished when comparing the outer genitalic morphology of the males.
