The capture of a consider-able number of Elatophilus (Euhadrocerus) crassicornis (Reuter, 1875) (Fig. 1), a speciestypical of the western part of the Mediterranean basin, was particularly interesting.The presence of Cardiastethus nazarenus Reuter, 1884, was reported by STICHEL(1959), but only in general terms and with no geographical or collection reference.NAT. CROAT. VOL. 17 No 3 213¿216 ZAGREB September 30, 2008Croatian Natural History Museum, Demetrova 1, Zagreb, CroatiaELATOPHILUS (EUHADROCERUS) CRASSICORNISEight female specimens were collected on the Cres (Stivan, 27.06.2002; Martin{}i-ca, 02.07.2003, 01.09.2005, 03.09.2005, 01.09.2006 (4 ex.)).Due to its antenna structure (with the second element strongly compressed atthe elliptic section) this taxon is placed in the subgenus Euhadrocerus Reuter 1884,neither species nor capture of which have been reported in the Adriatic or Balkans(PÉRICART, 1972; PROTI], 1998). Moreover, the total dimensions and the length of therostrum identify the specimens collected as the species E. crassicornis.However, it has to be mentioned that some biometrical differences exist betweenthe measurements of the specimens from Croatia and the published values (PÉRI-CART, 1968; 1972), confirmed by an examination of a female in the Natural HistoryMuseum of Genoa. In particular, the individuals examined have the following dif-ferences with respect to the others: third element of the rostrum shorter than thefirst; second element of the antennas five times longer than its maximum width214 Tescari, G.: Two species of Anthocoridae on P. nigra new to CroatiaFig. 1. Elatophilus (Euhadrocerus) crassicornis (Reuter, 1875)and never longer than 1.2 times the diatone, the scutellum always higher than thediatone. In any case, this series of morphological (biometrical) differences is part ofthe normal variance of this species (A. CARAPEZZA; J. PÉRICART, pers. comm.).The importance of this report is in the widening of the distribution area of thespecies to the Adriatic area and in the relatively constant presence of this species,which has always been believed to be rather rare.Collecting was carried out by sampling the foliage of the Pinus nigra trees or bycollecting specimens that had fallen from it.CARDIASTETHUS NAZARENUSThe C. nazarenus individuals were captured together with the aforementioned E.crassicornis individuals on Pinus nigra foliage. The individuals were two males of1.95 and 1.80 mm. (Martin{}ica, 01.09.2005; 01.09.2006). Some branches of the Pinussampled showed the discrete presence of lichens typical of the bark.The C. nazarenus was presumed to be present in the territory of Croatia: STICHEL(1959) had indicated the presence of this anthocorid in a generic manner without,however, indicating precise related data (»Jugoslawien«). PÉRICART (1972) himselfreports this same situation; PROTI] (1998), in her catalogue, does not mention thetaxon in the territory of ex-Yugoslavia. Finally, GOGALA (2004) reports its presencein Slovenia, the first confirmation for the upper Eastern Adriatic area.Therefore, this new record corroborates the Northern Mediterranean distributionof this interesting and localized anthocorid.The analysis (still partial) of the Heteroptera fauna tjat populates the Pinus nigrastands of Cres has led to the identification of very interesting taxa, both from thedistributional and the ecological point of view. After the first report in Croatia(TESCARI, 2004) of Leptoglossus occidentalis Heidemann, a neartic coreid in a fullphase of expansion in Europe, I was able to identify it on Cres seven times moreduring 2006, always on Pinus nigra.Elatophilus (Euhadrocerus) crassicornis, Cardiastethus nazarenus and Leptoglossusoccidentalis, therefore, represent entities well established in the studied territoryeven though they are reported as rare or as a first sighting. The faunistic richness ofan insular territory is well highlighted by these first results, obtained through re-search aimed at only one arboreal species.ACKNOWLEDGEMENTSI wish to thank A. Carapezza and J. Péricart for confirmation of the determina-tion of E. crassicornis, E. Heiss for assistance and C. Hancock for checking the draft.A special mention goes to Dr. R. Poggi of the A. Doria Museum of Genoa who en-abled me to examine a specimen of E. crassicornis deposited in the collections ofthat museum.Received February 25, 2008Nat. Croat.
