Little attention has been paid to the herpetological fauna of the Simbruini Mountains Regional Park, Latium (Central Italy). In this study, we surveyed 50 sites in the course of about ten years of field research, especially during the period 2005-2008. Nine amphibian species, four Caudata and five Anura, 60.0% out of the 15 amphibian species so far observed in Latium, were discovered in the protected area: Salamandra salamandra, Salamandrina perspicillata, Lissotriton vulgaris, Triturus carnifex, Bombina pachypus, Bufo balearicus, Bufo bufo, Rana dalmatina, Rana italica. Physiography of sites has been detailed together with potential threatening patterns. For each species the following topics have been discussed; ecology of sites, altitudinal distribution, phenology, sintopy. Salamandra salamandra and Bombina pachypus are at higher risk. The importance of the maintenance of artificial/natural water bodies for the conservation management of amphibian population of this territory is discussed.

Abstract An attempt was made to evaluate the diversity and distribution of cave bats of Latium (Central Italy). Data about twelve species were examined and their frequency have been determined. Only Rhinolophus ferrumequinum and R. hipposideros are really frequent: the other species are more or less localized. The average number of species (2,63) has a great importance for future contro1 of cave bat populations. Similarity between cave bat coenosis was examined, together with the altitude distribution of five species. The relation between altitudinal range, number of caves and average number of species was also studied: between 801 and 1000 m.s.l., the last parameter increases considerably and a hypothesis is presented to explain the phenomenon. This troglophilous bat fauna is probably very rich in species in comparison with other Italian bat communities. Riassunto Viene svolta un'analisi delle cenosi di Chirotteri troglofili dell'Italia Centrale. Vengono esaminati i dati relativi a 12 specie; di ciascuna è stata determinata la frequenza. Rhinolophus ferrumequinum e R. hipposideros risultano le specie più frequenti. I1 numero medio di specie (2,63) assume un importante significato ai fini del controllo delle chirotterofaune troglofile. L'affinità tra le chirotterofaune è stata esaminata, analogamente alla distribuzione altitudinale di cinque specie. Range altitudinale, numero delle cavità e numero medio di specie sono comparati: fra 801 e 1000 m, si osserva un aumento dell'ultimo parametro e vengono formulate ipotesi per spiegare il fenomeno. La ricchezza di specie del Lazio viene evidenziata dal confronto con altre chirotterofaune troglofile regionali italiane.
