Laccophilus ceylonicus Zimmermann, 1919 View in CoL

( Figs. 3 View Figs , 20 View Figs )

Laccophilus horni Régimbart, 1902: 468 View in CoL (original description); preoccupied by Branden, 1885: 21.

Laccophilus ceylonicus Zimmermann, 1919: 123 View in CoL (replacement name); Vazirani, 1972: 119: (lectotype designation); Brancucci, 1983: 253 (description, new records).

Type locality. Nalanda [= Srí Lanka, Central Province, Nalanda].

Material examined. 28 specimens. INDIA: Maharashtra : 1 male 6 females, 100 km SW Poona, Mahabaleshwar , 1300 m, 16 September 1991, coll. R. Schuh ( GWCV, NHMW) ; 12 ex., same locality, but 1400 m, 30 September–2 October 2005, coll. J. Bezděk ( NMPC, PMCB) ; 2 females, 120 km NE Mumbai, Igatpuri env., 19.42,17N 73.33,06E, 1–12 August 2002, coll. P. Šípek & M. Fikáček ( NMPC) . Orissa: 1 male, Daitari Distr., Jajpur – Keonjahr [ Keonjhargarh ], trapped during monsoon 1967, coll. G. Topál ( NHMB). SRI LANKA: 1 female, Nalanda , 1899, coll. W. Horn ( ZSMG) ; 1 male, Puwakpitya , hiver [winter] 1906–1907, coll. E. Bugnion ( GWCV) ; 1 female, Veli Oya Belihuoya [most probably Belihul Oya], 8 December 1970, coll. Starmülluer ( GWCV) ; 2 males 1 female, Dambulla env., 300 m, 19 April–9 May 1991, coll. J. Kolibáč ( NMPC, NHMB).

Diagnosis. Medium sized, elongate oval species (body length 3.8–4.1 mm). Elytra with subbasal testaceous band sinuous, narrow, well separated from elytral base ( Fig. 3 View Figs ). Apical part of median lobe in lateral view with distinct bulge on dorsal side; apex with pointed tip ( Fig. 20 View Figs ).

Distribution. The species was described and known previously only from Sri Lanka ( Brancucci, 1983). The present records from Maharashtra and Orissa allowed us to expect that is widely distributed also in the Indian subcontinent ( Fig. 40 View Figs ).
