Diagnosis

This new species is easily distinguishable from all the other Soulierana Bucher & Bouteille gen. nov. by its small size (<7.0 mm) and its typical pale red colouration and the colouration of its legs, but also by the length of its long rostrum reaching the anterior margin of the abdomen, a pronotum 2.1 times as wide as long and short tegmina embracing the abdomen.

Etymology

‘ Kely ’ means ‘small’ and ‘ mena ’ ‘red’ in Malagasy, ‘ kelymena ’ therefore refers to the small size and colour of the species.

Description

TOTAL LENGTH. Between 6.3 and 6.7 mm (holotype is 6.7 mm).

HEAD. Head in dorsal view 2.8 times wider eye to eye than long in midline, vertex short with anterior margin rounded. Ocelli closer to each other than to eyes. Antenna with large pedicel bearing long flagellum. Postclypeus with narrow central furrow strongly marked by keel on each side. Long rostrum reaching ventral anterior margin of abdomen.

THORAX. Pronotum in dorsal view 2.1 times as wide as long in midline. Anterior margin rounded, with two central small dimples framed on each side by bigger one. Posterior margin slightly wave-shaped. Scutellum triangular with large anterior base and sharp posterior point.

TEGMINA. Short tegmina, embracing the abdomen. Veins clearly distinct and few bumps on apical part where network is not dense with only few cells.

MALE GENITALIA. Subgenital plates elongated and curved laterally to sharp apex wearing setae. Sterno-lateral plates slightly rounded. Aedeagus developed anteriorly in one-pointed protrusion; ventral margin declining in convex arc to form protuberance and going straight up to apical part. Parameres bearing rounded lobe on dorsal margin and with hook-shaped apical apex. Aedeagus bifid, posterior margin ending in acute apex bearing teeth on each side in its last third. Anterior margin with slim extension, long as one third of posterior one, ending in rounding apex. Anterior protrusion pointing into rounded tooth.

COLORATION. Body pale red. Tegmina of same colouration with dark red veins and some of apical cells dark brown. Tibia and tarsus of first pair of legs dark brown. Midlegs with apical half of tibia and tarsus dark brown. Hindlegs with single black tibial spine; distal extremities of tibia and tarsus dark brown, rest of each pair of legs pinkish ochre.
