Photographic records of some new or little known Anisoptera in the fauna of Slovenia (Gomphidae, Libellulidae)

In addition to Sympetrum fonscolombei (Sel.). published recently by I. GEISTER (1991, Annales, Koper/ Capodistria 1: 47-50), two more novelties were evidenced during the 1991 season, to which the confirmation of a more than a century old record of a third species is to be added. Onychogomphus uncatus (Charp.). — Slrzen Rivulet, in the dried up Cirknica Lake. Inner Camiola, 1 cf. 5-VIII-1991. – It landed on a sandy cart track by the stream, and it was identified on the basis of a photograph, showing clearly the broad thoracic fasciae pattern, the entirely black vertex coloration, and the intensely yellow terminalia; the structure of the upper appendages is not visible, therefore the confirmation by a voucher specimen remains highly desirable. — Aside from the old and questionable Selysian record from Upper Austria (1858. Manage, gomphines. p. 28). this would be the easternmost record of this species. In view of the appreciable geographic distance from the known (isolated) localities in southern central Europe (e.g. Schaffhausen), it is perhaps worthwhile to note that the biogeographically similar, west mediterranean Gomphus pulchellus Sel. recently shows a very rapid eastward range extension (cf. E. GACHTER, 1988. No nil. odanatol. 3( I): 6-8 and, above all, W. SCHNEIDER. 1984, Em. Z.. Essen 94(8): 109-111).
