Tinea araliae Fr.
(Taf. II, Fig. 7.)
Auf dem Blatte einer Aralie gewahrte ich wurmförmige Furchen, welche schmal beginnen und allmälig, ihrem Verlaufe entlang, sich erweitern. Sie kommen in verschiedenen Grössen vor, zuweilen in Klumpen dicht bei einander, wobei die dünnen Enden von einem Punkte zu entspringen scheinen. Das abgebildete Exemplar ist an der weitesten Stelle 0.4 mm breit, der Anfang und das Ende liessen sich nicht mit Sicherheit constatiren.
Die ganze Erscheinung erinnert auffallend an die Gänge der Minirmotten, wie wir Sie häufig in den Blättern der jetzigen Flora antreffen.
Das abgebildete Exemplar stammt von Vyšerovic und ein zweites fand ich auf einem Blatte aus dem schwärzlichen Schieferthon der Perucer-Schichten von Mšeno bei Budin.
Tinea araliae Fr.
(Plate II, Fig. 7.)
On the leaf of an Araliaceae I noticed worm-like furrows, which start narrow and gradually expand along their course. They occur in different sizes, sometimes in clumps close to each other, where the thin end of seem to emerge from one point. The depicted specimen is 0.4 mm wide at the widest point, the beginning and the end cannot be determined with certainty. The whole appearance is reminiscent of the galleries made by mining moths, as we often see in the leaves of the extant flora. The depictur specimen comes from Vyšerovic and I took a second on a leaf from the blackish slate thon of the Perucer layers of Mšeno near Budin.

The very schematic drawing does not show much else than a long gallery mine, it could also be a gracillariid mine such as Phyllocnistis. Since no nepticulids are known to feed on extant Araliaceae, but several Gracillariidae (particularly the genus Eumetriochroa Kumata, with mines similar to Phyllocnistis) do feed on this family ((Kobayashi et al, 2011)), we tentatively remove this species from Nepticulidae.
