Malagasyprinus diana sp. n. Figs 44-61

Type locality.

Madagascar, Diana province, Forêt d’Orangea.

Type material examined.

MADAGASCAR: Holotype, glued on its side on a triangular mounting point, with male genitalia extracted, glued to the same mounting point as the specimen, with the following labels: “♂” (printed), followed by "MADAGASCAR: Province / d’Antsiranana Forêt / d’Orangea, 3.6 km 128° / SE Ramena Elev. 90m / 22-28 February 2001" (printed); followed by " 12°15'32"S, 49°22'29"E " / coll. Fischer, Griswold et al. / California Acad. of Sciences / pitfall trap - littoral rainforest / collection code: BLF3127" (printed); followed by: "CASENT /8065747" (printed); followed by: " Malagasyprinus diana / sp. n. Det. T. Lackner & / Y. Gomy 2013 HOLOTYPE (red label, printed) (CAS). Paratypes (one of the male PT is sputter coated with gold): 1 ♂, same data, but "CASENT / 8065750" (CYG); 1 ♂, same data, but "CASENT / 80657501" (CAS). 1 ♂, same data, but "CASENT / 8065748" (TLAN). 1 ♀, same data, but "CASENT / 8065749" (CAS).

Diagnosis.

Body measurements: PEL: 2.20-2.30 mm; APW: 0.70-0.80 mm; PPW: 1.75-1.90 mm; EL: 1.40-1.50 mm; EW: 2.00-2.10 mm. Generally, this species has the deepest longitudinal pronotal depression and the largest area of the pronotum covered with deep longitudinal wrinkles. The elytral ‘mirror’ of Malagasyprinus diana is also the largest of the three species (compare Figs 1, 26 and 44 for the elytral sculpture of the three species). Furthermore, its carinal prosternal striae are rather widely separated, not approximate medially, only slightly diverging apically (compare Figs 8, 32 and 50 for the configuration of the prosternal striae among the three species) and the prosternal process is even, not depressed on anterior two-thirds. By the aedeagus (compare Figs 40 and 60) Malagasyprinus diana is most similar to Malagasyprinus perrieri , differing in the shape of 8th sternite.

Distribution.

Known only from the northernmost tip of the island, region of Diana, northern Madagascar (Fig. 62).

Biology.

Collected in littoral rainforest by the method of pitfall trapping.

Etymology.

Patronymic, named after the region of Diana, where this species has been collected.
