Material examined and depository. CAR. Dzanga-Ndoki NP, Lake 1, on an Ayous ( Triplochiton scleroxylon , Sterculiaceae ) (platform 40m), 29.II.2012 (light), P. Annoyer (1♂ holotypus) ( MSNG); 9–10.II.2012 (light) (1♂ paratypus); 14.II.2012 (1♂ paratypus) ( BMPC); 19–20.II.2012 (light) (1♂ paratypus); 20.II.2012 (light) (1♂ para- typus) ( PAPC); Lake 3, 25–26.II.2012 (light) (1♂ paratypus) ( PAPC).

Diagnosis. D. brevistylata n. sp. is very similar to D. irregularis and D. occulta , but styli are very short, differently from some other species of the genus. Also in D. occulta styli are rather short, but cerci are differently shaped [compare Figs. 31–46 of Massa (2015b) with Figs. 44–46 of this paper].

Description. Male ( Fig. 43 ). General habitus and colour pattern. Green with yellow legs. Fastigium of vertex and fastigium of frons yellow, face yellow. Tegmina green. Head and antennae. Eyes oval-roundish, antennae long and thin, yellowish. Fastigium of vertex forming a ridge with sulcus; fastigium of frons conical; both fastigial separated by deep gap. Thorax. Anterior margin of pronotum straight, posterior rounded. Tegmina broad with rounded margin. Stridulatory file on underside of left tegmen 1.5 mm long, almost straight, with ca. 80 evenly spaced teeth ( Fig. 47 ). Legs. Tympana of fore tibiae open on outer, conchate on inner side, whole area slightly inflated. Fore coxae armed with a thin spine. Fore femora on inner side with 6–7 ventral spines, mid femora with 4–5 outer ventral spines, hind femora with 7–8 outer and 8–10 inner ventral spines. Fore tibiae with 2–3 inner and 4–5 outer ventral spines. Mid tibiae with 6–7 pairs of spines, plus 1 spur on dorsal inner side. Hind tibiae with numerous spines; 3 spurs apically on each tibia. Abdomen. Cerci stout and incurved with pointed tip; subgenital plate longer than wide, with a concave posterior margin, very short styli ( Figs. 44–46 ).

Measurements (mm). Body length: 18.8–18.9; length of pronotum: 4.8–5.4; height of pronotum: 4.4–4.6; length of hind femora: 18.0–19.0; length of tegmina: 28.5–29.0; width of tegmina: 18.0–19.0.

Female ( Figs. 49–50 ). One female collected with the male on 14.II.2012 could be the other sex of D. brevistylata , but when in doubt we report only photographs of ovipositor and subgenital plate and the following measurements (in mm): body length: 20.0; length of pronotum: 5.3; height of pronotum: 4.7; length of hind femora: 17.2; length of tegmina: 32.1; width of tegmina: 8.9; length of ovipositor: 3.9.

Etymology. The name brevistylata derives from Latin “brevis” (= short) and “stylus” (styli, plural) and means “with short styli”, the main character of the species.

Distribution. D. brevistylata is known only from Dzanga-Ndoki NP.
