Krzeminski, Wiesław, Kania, Iwona & Nel, André, 2012, Probittacomorpha brisaci n. sp. (Ptychopteridae, Bittacomorphinae) from the Late Miocene of Montagne d’Andance, Saint Bauzile, Ardèche (France), Zootaxa 3521, pp. 80-88: 82-84

Probittacomorpha brisaci  Edit n. sp.

( Figs 1–3)

Diagnosis. Wing with well developed anal lobe; this character is diagnostic to the genus being present also in the second species, P. christenseni  Edit . Cross-vein r-m leaving at 1 / 9 length of R 4 + 5 and m-cu positioned somewhat posterior to the base of fork of M 1 + 2 and M 4 distinguish a new species from its congener.

Etymology. The species name is a patronym for Mr. Patrick Brisac, who found and donated the type specimen.

Material examined. Holotype NMNHN.F. A 46700, male, from the Late Miocene of Montagne d’Andance, Saint Bauzile, Ardèche, France. Specimen is housed in the Laboratoire de Paléontologie, MNHN, Paris, France.

Description. ( Fig. 1). Body length 17 mm; wing length 13 mm, wing width uniform through length, anal lobe distinct.

Head. Antennae not visible, maxillary palpi with only one segment visible.

Thorax. Wings ( Figs 2 A –C) long, rather narrow; Sc long, ending opposite half of vein R 4 + 5; sc-r absent; R 1 long, strongly curved apically; section of R 1 distad of cross-vein r-r (R 2) twice the length of r-r; Rs very short, approximately 1 / 5 length of R 2 + 3 and half of R 3 length; R 2 + 3 over two times as long as R 3, running parallel and unusually close to R 1; cross-vein r-m at 1 / 9 length of vein R 4 + 5; R 4 and R 5 of same length; R 4 + 5 approximately 1.5 times as long as R 4; Rs, R 2 + 3, basal part of R 4 + 5 and cross-vein r-m much thicker than other veins; vein M 1 + 2 and M 4; m-cu connected to M 4 a little distally of base of fork of M 1 + 2 and M 4; Cu strongly waved in distal part; A 1 short and arcuate.

All legs ( Figs 3 A –F) preserved, tibial spurs absent; first tarsomeres cylindrical and slender. Abdomen long, narrow. Male terminalia partly preserved, but not enough for a reconstruction.
