Antiquatortia Brown & Baixeras , gen. nov.

Type species: Antiquatortia histuroides Brown & Baixeras , sp. nov.

Description. Head: Vertex rough-scaled, frons with narrow scales. Antenna slender, slightly serrate, ca 0.4 times length of forewing, lacking conspicuous sensory setae, with two rows of scales per flagellomere. Ocelli present. Chaetosemata not visible. Labial palpus long, porrect; second segment ca 4.0 times length of first and third segment, expanded medially on dorsal side, third segment slender, rod-like, slightly tapering apically. Maxillary palpus not visible. Haustellum well developed, coiled, unscaled at base, with stout sensilla on distal half.

Thorax: Foreleg tibia with epiphysis; mid- and hindtibia with two pairs of spurs, the more medial spur longer; tarsus with apical spines on ventral side. Forewing discal cell length about 0.6 forewing length; all veins (Sc, R 1 -R 5, M 1 -M 3, CuA 1 -CuA 2 and 1A+2A) present and separate, R 5 extending to costa; neither chorda nor M-stem evident. Patches of upraised scales on the forewing. Hindwing with costa slightly sinuate, with a concave region preapically ( Figs 2 a–b); Sc+R 1 and Rs approximate at base, M 2 and M 3 apparently parallel; M 3 and CuA 1 stalked; frenulum with three acanthi.

Abdomen: Female genitalia with papillae anales weak, but apparently flat.

Diagnosis. In wing venation Antiquatortia is similar to Polyvena , but in Polyvena the chorda and the M-stem are present, whereas both are absent in Antiquatortia . Both specimens possess patches of what appear to be upraised scales on the forewing, a feature characteristic of both sexes of Polyorthini and Tortricini , although occurring sporadically elsewhere in Tortricidae ( Horak 1998) . Because the forewing pattern is obscured in both fossils, no comparison of pattern can be made. In addition, because Polyvena is a male and Antiquatortia a female, no comparisons regarding other external features are particularly relevant (i.e., number of acanthi in the frenulum, male secondary features, etc.)

Etymology. The genus name is a Latinized derivative name freely inspired in the contraction of the Latin word

“antiqua” (meaning old, ancient) and the type genus of the family Tortricidae “ Tortrix ”. It is feminine in gender.
