Genus Melobasina Kerremans, 1900

( Figs. 54–70 , 123, 128 )

Melobasina Kerremans, 1900b: 68 . Type species: Melobasina apicalis Kerremans, 1900 , by monotypy.

Melobasina: KERREMANS (1903) : 138 (key to genera), 144 (characters; in Buprestini : ‘Buprestites’); OBENBERGER (1923): 17 (note); OBENBERGER (1930): 420 (catalogue; in Buprestini : ‘Buprestites’); BELLAMY (1985): 420 (catalogue; in Buprestinae : Buprestini ); HOŁYŃSKI (1993): 13 (list), 27 (comment; in Buprestinae : Buprestini : Haplotrinchina ); BELLAMY (1997): 76 (list; with Nesotrinchus in synonymy; in Buprestinae : Buprestini : Haplotrinchina ); VOLKOVITSH (2001) : 96 (note; in Chalcophorinae [now Chrysochroinae ]: Poecilonotini : ‘ Nesotrinchus generic group’); BELLAMY (2002):62 (catalogue; with Nesotrinchus in synonymy; in Chalcophorinae : Psilopterini : Haplotrinchina ); BELLAMY (2003): 41 (catalogue; with Nesotrinchus in synonymy; in Chrysochroinae : Poecilonotini : ‘ Nesotrinchus generic group’); BELLAMY (2008): 624 (catalogue; with Nesotrinchus in synonymy; in Chrysochroinae : Poecilonotini : ‘ Nesotrinchus generic group’).

Diagnosis. This genus is characterised by navicular, not caudiform elytra ( Figs. 54 , 59, 66 ), missing supraantennal carinae, antennal sockets margined by sharp but not elevated edge, and flat frons ( Figs. 56 , 62, 68 ); lateral pronotal margins nearly straight, moderately converging anteriad, lateral keels obtuse ( Figs. 55 , 61, 67 ); anal ventrite of female sharply trispinose ( Figs. 58 , 64 ) or median spine reduced into small tooth ( Fig. 70 ); visible abdominal tergites moderately transverse, terminal tergite (T7) longer than wide; wing ( Fig. 123 ) with anal veins AA 4 +AA 3b +AP 1+2 and AP 3a free.

Remarks. BELLAMY (2002, 2003, 2008) misinterpreted the note of HOŁYŃSKI (1993: 27) as a synonymisation of the genera Nesotrinchus and Melobasina (see above).
