ABSTRACT

This paper presents the current knowledge on the odonate fauna of the Iglesiente (SW Sardinia). Historical data and recent investigations have resulted in a total of 28 species (11 Zygoptera and 17 Anisoptera) for this area, representing 67% of the species known from Sardinia. Additionally, new data are presented for other areas of Sardinia on the following species, considered rare and/or protected: Lestes macrostigma (Eversmann, 1836), Sympecma fusca (Van der Linden, 1820), Coenagrion scitulum (Rambur, 1842), Lindenia tetraphylla (Van der Linden, 1825), Orthetrum nitidinerve (Selys, 1841), O. trinacria (Selys, 1841) and Brachythemis impartita (Karsch, 1890).

Key words: Odonata, Lindenia tetraphylla, Brachythemis impartita, species list, Sardinia, Italy.

RIASSUNTO

Gli Odonati dell'Iglesiente (Sardegna sud-occidentale) e nuovi dati su alcune specie rare o poco note della Sardegna (Odonata)

Sono esposte le conoscenze attuali sull'odonatofauna dell'Iglesiente (Sardegna sud-occidentale). Dati storici ed indagini recenti hanno evidenziato la presenza di 28 specie (11 Zigotteri e 17 Anisotteri), pari al 67% delle specie conosciute in Sardegna. Inoltre, sono segnalati nuovi reperti e osservazioni su sette specie rare provenienti da altre zone della Sardegna: Lestes macrostigma (Eversmann, 1836), Sympecma fusca (Van der Linden, 1820), Coenagrion scitulum (Rambur, 1842), Lindenia tetraphylla (Van der Linden, 1825), Orthetrum nitidinerve (Selys, 1841), O. trinacria (Selys, 1841) e Brachythemis impartita (Karsch, 1890).

INTRODUCTION and IV of the Habitats Directive, seems to have here one of its strongholds in Italy. The Odonata fauna of Sardinia is relatively well known In comparison to other parts of Sardinia, the odonate (eg. Bentivoglio 1905; Nielsen 1940; Bucciarelli et al. fauna of the "Iglesiente" has received even less atten- 1983; Utzeri & D'Antonio 2005) when compared with tion.

However, only 6 larvae hatched (fig. 3), two of which moulted once. Sympecma fusca This species seems rare in Sardinia and was known for the province of Cagliari only from some historic collections (see Bucciarelli et al. 1983).

Coenagrion scitulum C. scitulum is known only from a few localities in Sardinia (Nielsen 1940; Bucciarelli et al. 1983; D'Antonio 1989; D'Aguilar et al. 1990; Holuša 2008) and has been found on some of the minor islands as well (Utzeri & Cobolli 1993). Its presence in the Iglesiente could not be confirmed (e.g. D'Antonio 1989; Holuša 2008).

Lindenia tetraphylla In Europe this species occurs in the Mediterranean, where it is very localized and is considered "Vulnerable" (Kalkman et al. 2010). For Tuscany and for Sardinia populations have recently been reported (Terzani Fig. 3. A young larva of Lindenia tetraphylla (length 1.4 mm) 2002; Utzeri et al. 2006). Only four sites were known from Rio Flumini Mannu, near Assemini (photo by P.
