ABSTRACT
In the former Yugoslavia-period, the Brdo estate was inaccessible to investigators. Research became possible in 1991, when Slovenia gained its independence. In this paper, the first survey of the lacewing fauna (Neuropterida: Megaloptera and Neuroptera) of the estate is given. Among 31 species listed, two Sisyra- and three Chrysoperla-species are the most important records. The three green-lacewing species were reported for the first time for the Gorenjska region and the two Sisyrid species are important because they are included in the Red List of Endangered Neuroptera in Slovenia.

NOTE SU MEGALOPTERA E NEUROPTERA (INSECTA: NEUROPTERIDA) DELLA TENUTA
DI BRDO VICINO A KRANJ (SLOVENIA)
SINTESI
Nel periodo dell'ex-Yugoslavia, la tenuta di Brdo e rimasta inaccessibile ai ricercatori. Le prime esplorazioni al suo interno sono state approvate nel 1991, quando la Slovenia si e proclamata stato indipendente. L'articolo riporta i risultati dei campionamenti casuali di insetti olometaboli (Neuropterida: Megaloptera and Neuroptera) effettuati nel 2007. Fra le 31 specie segnalate, due del genere Sisyra e tre del genere Chrysoperla risultano fra i ritrovamenti piu importanti. Le tre specie di Chrysoperla sono riportate per la prima volta nella regione dell'Alta Carniola (Gorenjska), mentre le due specie di Sisyra sono importanti poiche compaiono nella Lista rossa delle specie a rischio di estinzione di Neuroptera in Slovenia.
Parole chiave: Megaloptera, Neuroptera, tenuta di Brdo vicino a Kranj
INTRODUCTION
Brdo pr¡ Kranju is a protocolar estate of the Republic of Slovenia positioned in the NW part of the country, at the foothills of the Kamnik-Savinja Alps (Fig. 1). In the former Yugoslavia, Brdo was President Tito's residence for a long period and therefore impossible to investigate faunistically. This first became possible in 1991, when Slovenia declared its independence.
The Brdo estate (Fig. 2) is a relatively small landscape of about 490 hectares consisting of a park and patches of primordial nature; the natural and anthropo-genous habitats thus interlace with each other. The Brdo Castle and the Congress Centre are positioned at the
edge of the Brdo Park. Whilst the park with two ponds represents a smaller part, the majority of the Brdo estate is characterized by various forest types, including coniferous, mixed and deciduous forests. Coniferous trees dominate. A stream running through the woodland creates a chain of seven ponds.
Knowledge on Neuropterida in Slovenian natural protected areas is poor. Only the Kozjansko Regional Park has been investigated so far (Klokocovnik ef a/., 2010). A decade ago, Iztok Geister started the research project »Survey of the fauna and flora of the Brdo pri Kranju estate— and the survey of Neuropterida was a part of the project. My aim is to present the results of occasional samplings of Neuropterida in the area in 2007.

All of the 31 species recorded in the area are common and widespread throughout Slovenia (Devetak,
1984, 1992a). In this small area, the species count is rather low especially for the low diversity of habitat types. Moreover, the sampling techniques used provide limited evidence on the species inhabiting the area. Other collecting techniques, like the use of light traps would certainly increase the number of species. The most outstanding results refer to the occurrence of two Sisyra- and three Chrysoperla-species. The two Sisyra-species are included in the Red List of Endangered Neu-roptera in Slovenia as vulnerable (Devetak, 1992b). The genus Chrysoperla species are insufficiently known for Slovenia and have been recorded for the first time for the Gorenjska region.

POVZETEK
Na območju Brda pri Kranju je bilo v času bivše Jugoslavije nemogoče izvajati favnistične raziskave. To se je spremenilo šele po osamosvojitvi, torej po letu 1991, ko je Slovenija postala samostojna država. V naključnih vzorčenjih leta 2007 smo na območju Brda nalovili 1 vrsto velekrilcev (Megaloptera) in 30 vrst pravih mrežekrilcev (Neuroptera). Med pomembnejše najdbe prištevamo dve vrsti spužvark (rod Sisyra) in tri vrste tenčičaric iz rodu Chrysoperla. Najdba spužvark je pomembna z naravovarstvenega vidika, najdba omenjenih vrst tenčičaric pa zaradi dejstva, da je rod Chrysoperla v Sloveniji še premalo raziskan.
