Description

TOTAL LENGTH. Between 9.0 and 10.0 mm.

HEAD. Median part of vertex strongly domed forming an obtuse angle with postclypeus. Frons concave in its middle. Postclypeus not exceeding anterior margin of head. Furrow on postclypeus wide, rounded at its upper extremity. Lateral bulges parallel, narrower than width of furrow and keeping same width over their entire length. In lateral view, postclypeus convex, forming an obtuse angle slightly pronounced. Rostrum reaching mesocoxae.

THORAX. Scutellum thick and main dimple deep; tip of scutellum slightly raised.

TEGMINA. Tegmina 2.5 times as long as wide with many tubers all over surface; anal vein on clavus strongly wave-shaped. Apical network dense with more than 20 concave cells per tegmina.

MALE GENITALIA. Under anal lobe, posterior margin of pygofer forming convex arc; margin becoming concave on ventral part. Subgenital plates shorter than length of pygofer; in lateral view, dorsal margin forming lobe on anterior part. Apical extremity of subgenital plates folded inwards with flattened internal part covered with setae. Sterno-lateral plates extend from pygofer in tapered shape; slightly dorsally oriented with convex apex. Dorsal margin of parameres bearing thin dorsal extension and posterior area excavated in its middle forming two separate bulbs. Aedeagus developed anteriorly in one-pointed protrusion at end of convex arc. Aedeagus bifid on apical part; posterior extension with serrated apex on last quarter. Anterior dorsal extension with a rounded apex representing one quarter length of posterior one.

COLORATION. Head red with end of rostrum and pedicels black. Pronotum and tegmina red; apical network sometimes with black colouration. In ventral view, thorax and abdomen fully red. Red legs with tibias fore and mid-leg black; all tarsi black.

Nomenclatural note

The type specimens designated by Fallou in the monograph of Monecphora rugosa were conserved in his personal collection located in the MNHN. The number of type specimens was not mentioned in his original publication. Nevertheless, in Fallou’s collection, the pinholes at the bottom of the collection boxes correspond to the number of specimens referenced. Only two female specimens were placed under the pinned label of Monecphora rugosa , with no supernumerary pinholes, suggesting that only these two specimens were considered to be the types. We choose to designate the better-shaped specimen as lectotype and the second one as paralectotype.
