Small size ( 17–22 mm ) and moderately robust ( Figs. 1A, B , 3A, B ). Coloration. Males are predominantly green, with few black stripes on their legs ( Figs. 1A, B ) and tegmina ( Figs. 1D, E ). Females have a brownish coloration ( Figs. 3A, B ). Head in frontal view ovoid, spaces between the antennal bases, as wide as half of the antennal scape; fastigium slightly elevated and narrow; eyes round and small, ocelli reduced and diffused; scaped armed with a tubercle at the apex of the inner margin, pedicel unarmed; moderately elongated maxillary palps ( Fig. 1C ). Thorax. Pronotum granular, pronotal disc noticeably longer than wide; anterior margin arched, with a forward projection, posterior margin straight and moderately thickened, outlined with a black/brown color ( Figs. 1B , 3B ). Lateral lobes of pronotum rectangular, two or three times as wide as deep (seen from a lateral view); humeral notch undeveloped ( Figs. 1A , 3A ). Sternum. Prosternum armed with two conical and conspicuous spines. Mesosternum: upper lobe broad, lateral lobes slightly elevated as a tuber-like spine; metasternum with no elevated lateral lobes, metafurcal groove narrow and U-shaped. Wings. Brachypterous, wings extending to the middle of the second abdominal tergite ( Figs. 1A, B , 3A, B ). Legs. Slender; fore-coxa armed with a conspicuous dorsal spine; all coxae are ventrally unarmed. Anterior and median coxaedorsally unarmed ( Figs. 1A , 3A ). Abdomen cylindrical, edges in each abdominal segment with a small and sharp prolongation on each side ( Figs. 1B , 3B ). Tenth tergite and epiproct without modification in both males and females ( Figs. 2A , 3C ). Male cerci cylindrical and armed with an inner apical spine ( Figs. 2A, B ). Male subgenital plate is almost as long as wide and with articulated styles ( Fig. 2C ). Robust ovipositor, as long as two-thirds of the length of the hind femur ( Fig. 3D ). Male genitalia. Completely membranous ( Figs. 2D–F ). Type species. Andeophylloides zarauzensis n. sp. by original monotype and designation. Etymology. The name refers to its Andean distribution and its similarity to Brachyplatyphylloides , one of the few brachypterous members of the tribe Platyphyllini . The gender of the name is being established as neuter. Distribution. High Andean Forest in the northeastern hills delimiting the Savannah of Bogotá , Colombia . Comparison. Andeophylloides n. gen. , Brachyplatyphylloides , and some species of Choeroparnops , Dohrn, 1888 are the shortened-winged taxa of the tribe Platyphyllini . Choeroparnops is easily differentiated from Andeophylloides n. gen. by having a larger size ( 30–50 mm ), robust appearance, pronotum granules very conspicuous, sometimes spiny. The tegmina cover at least half of the abdomen, and, unlike the other genera of the tribe, Choeroparnops has spines on the dorsal margin of the femora. Brachyplatyphylloides differ from Andeophylloides n. gen. by the robust appearance and brown coloration in both sexes; Brachyplatyphylloides males have some yellowish spots on the legs and a yellow stripe on the pronotal disc. The Andeophylloides n. gen. species described here also presents sexual dimorphism in coloration, males in life are lemon green (their color changes to yellow if they are preserved in alcohol), but females are brown. Andeophylloides n. gen. has the posterior edge of the pronotal disc and the sulcus of the pronotum with a similar organization to Brachyauchenus Brunner von Wattenwyl, 1895 . Although the coloration in both sexes is similar, these two genera differ because the wings of Brachyauchenus cover a large part of the abdomen. The size of Brachyauchenus castaneus Brunner von Wattenwyl, 1895 (the only known species for that genus) is greater than 30–40 mm ; the styles of the subgenital plate of the male are elongated and curved upwards and do not have modifications in the edges of the tergite, as it is usual in Andeophylloides n. gen.
