TYPE MATERIAL. — Lectotype (here designated): 1 ♂ ( MRSNT), bearing the following labels: 1) yellow, printed: “1 / 35”; 2) white, printed: “ Sard[inia]. / ( Monte Santo , / Bonnanaro vic. / colline interne)”; 3) red, printed: “ Geotrupes / matutinalis / Baudi, 1870 / LECTOTYPUS / Des. Dellacasa, 2005”.

Paralectotype: same data as lectotype 1 ♀ ( MRSNT).

TYPE LOCALITY. — Cantoniera di Monte Santo, Bonnanaro [Sassari, Sardinia]. In the original description Baudi recorded as type locality “Sardiniae interioris collibus”. In the manuscript catalogue (1891) of the Baudi collection preserved in Turin Museum we have found the more detailed locality that we deem should be considered the true type locality.

DISTRIBUTION. — Known only from Sardinia ( Fig. 3 ). Maybe the records from Corsica of Typhaeus typhoeus (Linnaeus, 1758) mentioned by several authors (cf. Dellacasa 2004: 45) have to be referred to this taxon or to Chelotrupes hiostius n. comb. We studied also specimens preserved in Paris Museum coming from localities that need to be confirmed: Sicile, 2 ex.; idem, leg. Krichl., 2 ex.; Graecia, ex coll. Pic, patria falsa, det. J. Baraud, 1 ex.; Grece, 1 ex.; Balearic Is., ex Musaeo Bates 1892, 1 ex.

BIONOMICS. — Flightless telocoprid species that seems to prefer sandy soils with dung of rabbits, hares, and goats; present all year round, distributed from sea level to high hills.

DESCRIPTION

Length 11.0-20.0 mm, very stout, strongly convex, almost glabrous; head and pronotum with metallic shine, elytra opaque. Blackish, antennae and legs black. Head with epistoma broadly rhomboidal, with median longitudinal gibbosity more or less coarsely, densely punctate; clypeus subtriangular with anterior angle widely rounded, laterally feebly inwardly sinuate, thinly margined, the edge elongately ciliate and distally upturned; genal cariniform sutures strongly raised; genae widely rounded; front smooth or sparsely punctate on disc, distinctly punctate on sides. Pronotum strongly transverse, moderately convex, with feeble antero-median rounded foveola on sides; the latter arcuate, thinly margined, the edge almost densely ciliate; hind angles obtusely rounded; base thinly margined, not inwardly sinuate. Scutellum broadly triangular, almost flat, alutaceous. Elytra very short, strongly convex, narrowly flattened before the epipleural carina; the latter sparsely ciliate; humeral callus feebly gibbous; striae usually distinct and more or less strongly punctate; intervals flat, alutaceous, superficially trasversely rugulose. Fore tibiae apical spur hooked apically. First segment of hind tarsi as long as following two combined.

Male: epistoma glabrous, with median longitudinal gibbosity feeble, almost smooth on disc, confusedly, rugosely punctate distally; pronotum laterally finely punctured; anteriorly with three horn-like apophyses, the lateral ones curved and inwardly convergent, subrugose almost to the base; the central gibbosity much smaller, regularly acuminate, straightly projected anteriorly; aedeagus illustrated on Figure 2B .

Female: epistome with median longitudinal gibbosity subtuberculiform at top, roughly punctate, with short pubescence on disc; pronotum irregularly punctate, punctation very fine and sparse on disc, coarser and denser anteriorly mostly on sides, deeply excavate anteriorly, front angles very distinct, subdenticulate and outwardly curved; at each side foveolate and with an outer tooth moderately raised; with a strong antero-median transverse carina.

REMARKS

The synonymy of C. matutinalis n. comb. versus C. hiostius n. comb. accepted in most of the pertinent literature,seems to be based on the Reitter’s comment (1893: 9): “Auf kleine, schwarze Individuen, ohne metallischen Schein dürfte der Geotr. matutinalis Baudi, B. 1870 . 70. begründet worden sein; die angegebenen Unterschiede sind durchaus keine specifischen.” Conversely the thorough study of numerous specimens allows us to conclude that this synonymy is incorrect; thus Chelotrupes matutinalis n. comb. is a valid species.
