Diagnosi s. – A species of the X. miser -group sensu Schimmel, 1999, that can be compared with X. girardi Schimmel, 1999 , too from Sulawesi, for the long antennae, it can be separated by the greater size and particularly for the elytral apices slightly emarginate.

Description. – Male.

Moderately shiny.

Coloration. – Entirely yellow-brown with vague, not well delimited, black maculae on the disk and sides of pronotum, disk of elytra in the humeral areas and after the middle; only the legs are lighter, yellowish; covered with dense, decumbent, yellowish pubescence.

Head. – Frons flat, anterior margin complete, sub-arcuate, directed downwards and just protruding above the clypeus; frontal-clypeal space not constricted and with a vestige of mid-longitudinal carina; punctuation coarse, punctures clearly umbilicate, contiguous or with shortest, shagreened intervals. – Antennae very long, exceeding of four articles the apices of posterior angles of pronotum, slightly serrated from the third article on; second article small, globous, long as wide, third-tenth sub-triangular, gradually slenderer, longitudinally sub-carinate; third shorter than the fourth; second and third, taken together, shorter than the fourth; last very slender, longer than the previous, with sub-parallel sides and asymmetrically constricted before the apex. (Fig. 37).

Pronotum. – Pronotum 1.07 longer than wide, widest at the apices of the posterior angles, very convex on the disk, abruptly sloping at sides, nearly vertically at base with a short, deep impression on the basal slope; sides very moderately and regularly arcuate, sinuate before the posterior angles, the latter vey elongate, acuminate, divergent, bicarinate; carinae at the same level, the inner shorter, the outer longer and slightly diverging from the lateral margins, the latter very fine, complete and not visible on a dorsal view; punctuation very dense and uniformly distributed; punctures on the disk simple with shortest, moderately shagreened intervals, gradually denser and clearly umbilicate towards the sides with shortest shagreened intervals.

Scutellum . – Very declivous, tongue-shaped, moderately convex, densely and roughly punctured.

Elytra. – 2.7x longer than pronotum and 2.9x longer than wide, convex; sides sub-parallel from base to behind the middle then gradually tapering to the apices, the latter very slightly emarginate and very shortly spiniform ( Fig. 49); striae regularly punctate-striate, interstriae sub-convex and densely punctured.

Prosternal process. – Gradually bent behind the procoxal cavities, not emarginate at the apex.

Aedeagus. – As in the Fig. 15 (length 2.0 mm).

Size. – Length 15.0 mm, width 3.43 mm.

Female. – Unknown.

Etymology. – This taxon is dedicated to the ornithologist Claudio Grispigni Manetti, a dear friend of the second author, for his support during the search for the equipment necessary for the preparation of the illustrations of this work.
