Marilia +altrocki Wichard 1986: 36 [Type locality: Germany (Baltic amber); ZSMC; male] DISTRIBUTION. Baltic amber.
Holotypus: paint (fig. 4) from that oligozaen eozaenen Baltic amber; kept in the amber collection BACHOFEN-ECHT with the collection No.: K 2 (the originally engraved numbering - K 2 - became away polished the investigation of the amber and the embedded Koecherfliege) in the Bavarian national collection for paleontology and historical geology Munich (BSP 1958 VIII K 2). The Koecherfliege is well received in the amber: Only the antennas are incomplete by a polished section in their length. The satteldachfoermige attitude of the forward wings causes that the underlying Hinterfluegel in the basal area and the genital are covered of dorsal. The amber is flat to the Koecherfliege polished, due to the age already easily more darkly colored and superficially with light decomposition breaks provided. Derivatio nominis: This fossil type of the kind Marilia is dedicated to Mr. W. W. ALTROCK, Munich, which energized me for the handling of the amber collection BACHOFEN-ECHT kindly. Heading: Remarkable flags that of mark of the kind Marilia are the very large, before-curved eyes, which hide the heading and on the vertex almost touch themselves. With Marilia altrocki frame n. amounts to the diameter of the eyes approx.. 1.53 mm and the outside viewing distance (eye width) approx.. 2.6 mm (fig. 5). The antennas are incomplete with the fossil Holotypus; the first member is approx.. 0.3 mm thickly and with approx.. 0.7 mm of length about as long as the heading; the second member is short and circular; the remaining antenna members are slim - so far still available - and point to a long antenna, which is than twice as long with the kind Marilia more like the forward wing. Since the forward wings of this type amount to 12 mm, an antenna length from at least 24 mm is therefore to be assumed to. The Labialpalpen is short and three-membered; the Maxillarpalpen is long and fuenfgliedrig. With the length of approx.. 0.7 mm are about of equal length the five Palpenglieder. Thorax: On the Pronotum a close seam with long, after caudal curved borstenhaaren is transverse to the body axle. This hair seam finds its lateral continuation in the trimming of borstenhaaren on the Tegula. Scutum and Scutellum 2. thorakalen segment are strongly before-curved and rather economically with fewer long borstenhaaren filled. The forward wings are slim with a length of 12 mm, at which base widens narrowly and to the Apex gradually. The Hinterfluegel is - so far recognizable broadly created, particularly since they gefalten under the satteldachfoermigen attitude of the forward wings are. The Fluegelaederung is in Abb. 6 represented. The three pairs of run legs have the spur number of 2,4,4. Abdomen: The male genital is visible by ventral, or ventrolateral (fig. 7). The lower appendices 9. Segment (genital feet, Clasper) are zweigliedrig and consist of a powerful, pear-shaped, basal member and a short, stiftfoermigen, apical member. The apical member points in medianer direction and has at its end a trimming of dark cathedrals. The upper appendices (appendices of praeanales, Cerci) appear narrow in lateral opinion and in the supervision broadly, in particular in the apical, loeffelfoermig extended area. Here wart-like collections with long hair on the surface - usually edge constant -, which is available likewise with same length at the basal member of the lower appendices, are. 10. Segment forms back segment, which is extended in the apical area by lateral wings, which point after vent ral for median a thin-walled. It covers dorsal the Penis, which bends in medioventraler direction, is briefly built and ends obviously with two Bulbi.
