Paratype female: same data as holotype. Depository MfN . Further paratype material: 1 male , same data as holotype ; 1 male Tanzania , Udzungwa Mountains National Park, Mangula Gate, July 2015 (CH8039). Collection C. Hemp. Description. Male. General habitus & colour . Eurycorypha species of uniformly green colour and elongate body shape ( Fig. 1 A ). Head and antennae : Scapus green and first couple of antennal segments green then getting darker towards end of antenna; very thin and not surpassing folded tegmina. Fastigium of vertex broad, more than 3 times as wide as scapus of antenna. Fastigium of vertex meeting equally broad fastigium of frons along well developed horizontal line with well developed median sulcus; fastigium at this point bulge-like elevated, medially below this bulge ocellus is located. Face with moderately developed frontogenal carinae, of triangular shape. Eyes typical for Eurycorypha , elongate and oval, green with faint white fascia in upper part. Thorax : Disc of pronotum depressed, thus lateral edges sharp; anterior margin of pronotum shallowly and broadly incurved, while posterior margin broadly rounded. Wings : Both pairs of wings fully developed; tegmina elongate, evenly rounded at tips, about 3 times longer than broad. Alae shiny with green area near tips which surpass tegmina when folded. Stridulatory file as in Fig. 2 , almost straight at posterior part, then slightly curved and teeth getting smaller. Legs : Fore coxa with almost straight spine. Fore femora on outer side with 3 small spines, mid femora with 2 small spines and hind femora near joints to tibiae with up to three brown-tipped spines. Fore tibiae without dorsal spine. Hind tibiae with four rows of densely set short brown-tipped spines, two outer spurs and three inner apical brown-tipped spurs. Abdomen : Light green without any pattern. Last abdominal tergite differentiated into two stout processes, densely to each other set short processes ( Fig. 2 C , arrows; D). Cerci stout, slightly incurved, with apical sclerotized tooth. Subgenital plate long with median keel at posterior third, forming two laterally compressed short processes at its posterior end, without styli ( Fig. 2 B ). Female. Similar to male but larger and more roundish ( Fig. 1 B ). Well developed ovipositor, strongly upcurved as typical for most Eurycorpyha species ( Fig. 3 A ). Subgenital plate flap-like, longer than broad with evenly rounded posterior margin ( Fig. 3 B ). Measurements (mm).—Male (N = 2). Body length 17.1–20.5. Median length of pronotum 4.9. Posterior femur length 14.8–15.2. Length of tegmina 29.7–29.8. Width of tegmina 9.7–10.5. Measurements (mm).—Female (N = 1). Body length 24.8. Median length of pronotum 5.0. Posterior femur length 17.0. Length of tegmina 35.3. Width of tegmina 12.6. Ovipositor 7.0.
