Flintoconis petorcana sp. n.

( Figs 26–29 )

Holotype: male, “ Chile: (Prov.) Petorca, Finca Talanquén , S La Lígua , Oct 1984 (?), L. E. Pena G.” – deposited in the Smithsonian Institution, Washington D. C .

Description: Length of the body 6.4 mm. The shape, structure and position of the head as it is detailed in the description of the genus. Eyes moderately large, black. Head capsule, palpi, antennae, abdomen and large part of the thorax brown. Pronotum – apart from the dark apodemes – light brown. Shoulder spots dark brown.

Tip of the antennae broken; remaining parts 65 (right) and 70 (left) segmented. Scape in lateral view about 1.5 times as long as broad, and 1.5 times as broad as the median flagellar segments. Pedicel almost two times as long as broad, flagellar segments 1.5 times as long as broad. The ordinary hairs bent forwards and situated irregularly. Short, straight setae are on the apical part of the flagellar segments.

Shape and structure of pronotum as detailed in the description of the genus. Legs dark brown. Length of fore wing 9.2 mm, of hind wing 8.6 mm. Hind wing distinctly wider than fore wing. The wing colour and pattern are similar to those of F. gozmanyi ; ground colour is dark greyish-brown, however, the fore wing with broad pale stripes and many spots of different size and irregular shape, thus larger part of the wing surface pale. Longitudinal veins and the stronger cross veins are brown. On both wings there are only a few short fringes. Outstanding setae of M are absent, but there is a somewhat stronger bristle at about the basal third of M and at the very basal part of Cua. The structure of the venation is similar to that of F. gozmanyi , but in fore wing of F. petorcana there is a Cua-Cup crossvein near to the middle of the wing, and there are distal M-Cua and Cua-Cup crossveins too. Longitudinal vein Aa forked near to the distal Cup-Aa crossvein. In the hind wing the fork of Rs is before the distal crossvein series, which contains a member between the branches of Rs. There is also a basal Cup-Aa crossvein. Because only the holotype only is available of F. petorcana , there is impossible to judge the taxonomic value of the above mentioned eidonomical differences between the two Flintoconis species.

Abdominal segments are moderately sclerotized with plicatures as in the description of the genus.

Male terminalia as in Figs 26–29 . On the caudal edge of the eighth sternite a small hairy knob is situated, with two longer setae. Ninth sternite is a strongly sclerotized plate, with a large, setose and curved projection. The ectoproct well sclerotized, with a moderately strong apodeme ending near to a short transverse apodeme at the base of the anterior appendage. Dorsal projection of ectoproct is a moderately large knob, with long setae. Caudal projection of ectoproct rounded distally. Anterior appendage of ectoproct moderately long, curved strongly invards, with short, hooked arms. At the base of this organ there is the prominent ninth gonapophysis, with distinct apodeme. Posterior appendage of ectoproct large, with a stout apical tooth, and with a branching basal apodeme. Paramere moderately long, with a bent stem, and with a short caudal part curved inwards. The tenth gonocoxal complex is a subtriangular sclerite, with irregularly situated hairs, with a strong, forked projection, and ending ventrally in a pair of slightly bent spurs.

Remarks: The new species is rather close to the above described type species of the genus Flintoconis . The main distinctive features of F. petorcana sp. n. are:

– moderately long anterior appendage of ectoproct;

– large posterior appendage of ectoproct, with stout apical tooth;

– subtriangular tenth gonocoxal complex, with strong, forked projection.
