Aplocnemus (Diplambe) januaventi Liberti, 2007

( Fig. 18 )

Aplocnemus (Diplambe) januaventi * Liberti, 2007a: 2 (Loc. typ. Gennargentu, Sardinia).

Material examined. Nuoro prov.: *Aritzo, 2009 ( CLI, MCSNM); *Bruncu Spina, 1974 ( CMO); *Desulo, 2009 ( CAN, CLI, MCSNG); *Lago di Gusana, 1995 ( CLI). Ogliastra prov.: Genna Silana, 2009 ( CLI); Genna Croce, 2009 ( CLI). Cagliari prov.: *San Vito, 1872 ( MCSNG); *Sarrabus, y-a ( MCSNG).

Chorotype. Strictly Sardinian. Affinities: among the Diplambe , this species appears rather peculiar and no hypotheses are attempted as to its affinities.

Notes. A rather rare species known from a limited number of specimens from the Gennargentu and Sarrabus areas only, and well characterized by the serrate male antennae, dark brown body with brown tarsi (paler than the tibiae), pale pubescence and elytral punctuation not as impressed as in A. (D.) duplicatus . Uncommon, probably altitudinal species, repeatedly collected on blossoming Erica bushes together with A. (D.) duplicatus .
