Abstract - Nevrorthus apatelios H. Aspöck, U. Aspöck et Hölzel, 1977 is recorded for the first time from Slovenia. The finding on the southwest slopes of the eastern Julian Alps represents the northernmost record for the family in Europe. A list of known localities for N. apatelios is provided in an appendix.

Izvleček - PRVA NAJDBA DRUŽINE NEVRORTHIDAE V SLOVENIJI
Prvič je v Sloveniji zabeležena najdba vrste Nevrorthus apatelios H. Aspöck, U. Aspöck et Hölzel, 1977. Najdba na jugozahodnih pobočjih vzhodnih Julijskih Alp je najsevernejša najdba družine v Evropi. Spisek znanih najdišč vrste N. apatelios je sestavljen v dodatku.

Recently, Letardi et al. (2005) reported the occurrence of Nevrorthus apatelios H. Aspöck, U. Aspöck et Hölzel (1977) in the Friuli region of northern Italy. This discovery significantly expanded the known geographic distribution of this primarily Balkan species, increasing its documented range by 3° latitude to the north and 4° longitude to the west. This unexpected discovery has suggested that nevrorthids, which are rarely collected and appear to be very locally distributed, may have a greater distribution in southeastern Europe than previously realized.
On 22 June 2008, the first author collected two adult male specimens of N. apatelios in the Goriška region of western Slovenia. The specimens were collected along Ročica stream, approximately one half kilometer east of the village of Drežnica, near
Fig. 1: Known distribution of Nevrorthus apatelios H. Aspöck, U. Aspöck et Hölzel. The new record reported here is marked with a star. Distributional data were obtained from Aspöck et al. (1977, 1980), Devetak (2003), Klapalek (1917), Letardi et al. (2006), Malicky (1984), Pongracz (1923), Popov (1993, 1990), and Saure (1989).
the town of Kobarid (precise collection locality: 46°15'24.38"N, 13°37'21.57"E, 634 m; source: Google Earth™). The first specimen, which afterwards proved to be teneral, was sighted on and then aspirated from a large mossy boulder in the center of the stream. The other was taken shortly after with a sweep net at about shoulder height as it flew upstream only a few meters away. Both specimens are presently in the personal collection of the first author. No other specimens were collected during searches by the first author and J. D. Oswald along the stream from the paved road leading from Drežnica upstream to Slap Sapota (Sapota Waterfall), a distance of approximately 0.4 km. This reach of the stream was heavily shaded by adjacent trees and shrubs. Collecting efforts at the site by the second author on 6-7 August 2008 (which followed many days of heavy rains) yielded no additional specimens.
The Ročica stream originates from several springs at the foot of the steep lower face of Mt. Krn (2245 m). Its exceptionally clear waters flow steeply downwards
among large limestone boulders, which is characteristic of streams flowing across the glacial-morainic alluvia of the eastern Julian Alps. From the terraced valley where Drežnica sits, the Ročica continues southward to the upper Soča Valley where it eventually feeds into the Soča River. The Ročica is similar to many small streams in the region, and it seems likely that other streams in the Soča River watershed may provide ideal habitat for nevrorthids, the aquatic larvae of which are known only from clean, high-grade streams and small rivers with fast currents.
The collection of N. apatelios near Drežnica represents the first record of Nevrorthidae from Slovenia (see Devetak 1984 for a review of Neuropterida recorded from Slovenia), and the northernmost record for the family in Europe (see Fig. 1, appendix). Drežnica lies approximately 75 air kilometers east-northeast of the Italian collecting localities reported by Letardi et al. (2005). Prior to its discovery in Italy and Slovenia, the northernmost known record for N. apatelios was from a locality in present-day Bosnia and Herzegovina, nearly 500 kilometers southeast of Drežnica (Aspöck et al. 1980). The discovery of nevrorthids in Slovenia adds further support to the idea that nevrorthids may be more widely distributed than previously anticipated in southern Europe, particularly in the clear, medium elevation streams of the southern Alps.

Appendix
List of recorded localities for Nevrorthus apatelios H. Aspöck, U. Aspöck et Hölzel, 1977.
