Macrosiagon bimaculata ( Fabricius, 1787)

( Figs. 16–17 )

Mordella bimaculata Fabricius, 1787: 218 . Type locality: Hungaria [= Hungary]. Macrosiagon bimaculata: BEDEL (1895) : 189 (new combination). Ripiphorus dubius Motschulsky, 1849: 128 , syn. nov. Type locality: Espagne [= Spain]. For the complete synonymy of M. bimaculata see BATELKA (2008a).

Type material examined. Ripiphorus dubius . SYNTYPES: 1 ex. ( Fig. 16 ) (much damaged, head and abdomen are missing) ( ZMUM), ‘ Ripiphorus / dubius m. / var. / Hisp. m. [hw] ’; 1 J ( Fig. 17 ) ( ZMUM), ‘Hisp. m. [hw]’.

Additional material examined. GREECE: 2 ♀♀ ( BMNH), ‘ Greece: Thassos / Crisso Akroyiali / nr. Potamia [p] / 23.vii.1972 [hw] / M. I. Russel [p] ’; 1 ♀ ( BMNH), ‘ Thasso / Is. [p] // Emenadia bimaculata [hw] // G.C. Champion coll. / B.M. 1927 – 409 [p] ’; 1 J 2 ♀♀ ( SMNS), ‘ Graecia 6.75 / Mesolongion / Folwaczny [p, blue label] // J [respective ♀, p] ’. TUNISIA: 1 ex. ( NMPC), ‘C-TUNISIA- Kasserine pr. / N.P.Chembi env. (Mts. / Chembi ) 35°11′N 8° 44′E / S. Kadlec lgt. 31.V.2005 [p] ’.

Remarks. Ripiphorus dubius was a forgotten name: after it was published by MOTSCHULSKY (1849), it was forgotten until being listed by BATELKA (2008b) in ‘ Ripiphoridae , nomina dubia’. Both syntypes of R. dubius are in all respects identical with Macrosiagon bimaculata and therefore Ripiphorus dubius is placed in synonymy with the latter.

Distribution. Palaearctic species. From Spain and North Africa to Kazakhstan. From Greece it was reported only from Peloponnese Peninsula ( BATELKA 2007b), recorded here for the first time from Thassos Island and continental Greece. From the North Africa it is known from Morocco, Algeria and Egypt. From Tunisia it is recorded here for the first time.
