Laccobius (Glyptolaccobius) egregius Gentili, 1995 View in CoL

( Figs. 8-11 View Figs )

Laccobius (Glyptolaccobius) egregius Gentili, 1995: 252 View in CoL . Laccobius (Glyptolaccobius) egregius: HANSEN (1999) View in CoL : 130; HEBAUER (2002): 13.

Type locality. India, Uttar Pradesh, Kumaon, Gori Valley, 2300 m a.s.l.

Type material examined. HOLOTYPE: J, 1.8 × 1.1 mm ( NHML): ‘ Gori R. Valley / Kumaon , India / 7000 ft H.G.C. // E. Gentili det. 1994 / Laccobius J / egregius m. // [red label] Holotypus’ . PARATYPES: 2 JJ 2 ♀♀ ( NHML, MSNV) same data as holotype ; 1 J ( NHML): ‘ Gori R. Valley / Kumaon , India / 5000 ft H.G.C. // ; 1 J NHML: // Dhabari, C. Almora / H.G.C. X.1926 ’.

Additional material examined. INDIA: UTTAR PRADESH, N Kumaon, Gori R. Gorge, 1400-2600 m a.s.l., H. G. Champion leg., 1 J ( ISNB): ‘Knisch det. 1925 / Laccobius s.str. affinis Kn. // Coll. A. Knisch / COTYPUS // Laccobius egregius J / E. Gentili det. 2003’. This specimen is a syntype of L. affinis .

Differential diagnosis. Laccobius egregius belongs to the group with unordered elytral punctures and curved hind tibiae. Within the group it is characterized by the dark elytra without clear spots and stripes, thus resembling L. affinis and L. incisus . It is chiefly distinguishable from these two species by the shape of the aedeagus ( Figs. 8-11 View Figs ), with parameres excised along interior margin. It also has light shagreen and lacks black hairs on the head and pronotum, and the parasutural furrow does not reach the elytral apex.

Distribution. India (Uttar Pradesh).
