Description

Small to medium sized (body lengths: ♀♀ 104.0- 147.7 mm incl. subgenital plate, ƋƋ 60.0- 79.4 mm), moderately elongate and slender Cladomorphini . Ocelli lacking in ♀♀, reduced but visible in ƋƋ. Body of ♀♀ slightly oval in cross-section, cylindrical in ƋƋ. ♀♀ apterous, ƋƋ with fully developed alae (24.2- 39.4 mm) and scale-like tegmina. Complete surface of thorax densely granulose in ♀♀; more minutely and sparingly granulose in ƋƋ. Abdomen smooth or very sparingly granulose. Head longer than pronotum, longer than wide, oval; vertex either flat or very gently rounded, unarmed. Antennae of ♀♀ longer than head, pro- and mesonotum combined, of ƋƋ longer than combined length of head and complete thorax. Scapus rectangular, about 1.5 × longer than wide and dorsoventrally compressed. Mesothorax elongate, at least 2 × longer than head and pronotum combined. Meso-, metasternum and sternites II-VII of ƋƋ with a more or less distinct, longitudinal median carina; simple in ♀♀. Median segment slightly longer (♀♀), or about 3 × longer than metanotum in ƋƋ. Tegmina of ƋƋ oval, slightly convex and indistinctly longer than metanotum. Alae at least covering tergites II-IV; anal region transparent. Abdomen longer than head and complete thorax combined. Abdominal segments II-VII of both sexes distinctly longer than wide and parallel-sided. Sternite VII of ♀♀ lacking a praeopercular organ. Tergite IX of ƋƋ strongly elongated, of bone-like appearance and at least 2 × longer than anal segment. Anal segment of ♀♀ with a fine median carina; of ƋƋ strongly broadened towards the posterior, transverse. Cerci of ♀♀ very small, slender and distinctly tapered towards the apex. Cerci of ƋƋ prominent, dorsoventrally flattened, and broadened towards the apex which is obtuse and angled inward. Vomer elongate, roughly triangular and distinctly pointed apically. Poculum of ƋƋ prominent and strongly convex, posterior margin bi-dentate. Gonapophyses of ♀♀ filiform and projecting considerably over the anal segment. Subgenital plate of ♀♀ very elongate, lanceolate, pointed apically and projecting over the anal segment by at least the combined length of tergites VIII-X. Legs very slender, elongate and completely destitute of spines or teeth in ƋƋ. In ♀♀ rather short and stout, with all carinae of the femora and tibiae distinct and more or less elevated or undulate. All carinae unarmed (at best minutely granulose) and 1 or 2 sub-apical teeth on the antero- and posterventral carinae of the meso- and metafemora. Profemora triangular in cross-section; medioventral carina very prominent, ledge-like and strongly approaching anteroventral carina. Meso- and metafemora and tibiae trapezoidal in cross-section, medioventral carina distinct. Basitarsi as long as following three tarsomeres (♀♀), or distinctly longer than remaining tarsomeres (ƋƋ) combined, simple. Dorsal carina of probasitarsus very slightly raised in ♀♀.

Eggs unknown.

Differentiatial diagnosis. Characterized amongst Cladomorphini by the densely granulose thorax of ♀♀, and prominent, distinctly hook-like and dorsoventrally flattened cerci of ƋƋ.

Related to Jeremia Redtenbacher, 1908 (Type-species: Jeremia grossedentata Redtenbacher, 1908 ), but distinguished by: the more slender body; more elongate and less globose head; densely granulose thorax; lack of distinct spines on the meso- and metapleurae and sterna; lack of dorsal lobes on tergite VII; considerably longer, lanceolate subgenital plate and lack of distinct spines on the medioventral carinae of the meso- and metafemora and tibiae. From Hirtuleius Stål, 1875 (Type-species: Hirtuleius laeoiceps Stål, 1875 ) Jeremiodes gen. nov. differs by: the flat and elongate head; lack of tubercles on the meso- and metanotum; lack of lateral lobes on tergites VI and VII and apically pointed subgenital plate. For a more detailed differentiation between Jeremiodes gen. nov., Jeremia and Hirtuleius see table 1 below. As the males of both Jeremia and Hirtuleius are not known, the distinguishing characters define to females only.

Etymology. The generic name “ Jeremiodes ” mirrors the relation to Jeremia Redtenbacher, 1908 .

Distribution. So far recorded from French Guiana and the tropical lowland regions of eastern Peru and Bolivia, east of the Andes. Most certainly this genus is distributed in the complete Amazon basin.
