description: <i>Sucinoptinus brevipennis</i> sp. n. M a t e r i a l. Holotype. Possibly male. SIZK D-2295, Dubrovitsa, Rovno amber, Late Eocene (fig. 1, <i>2</i>). Syninclusions: Mycetophilidae, Acari (Parasitengona), numerose stellate hairs. D e s c r i p t i o n. Length: 1.6 mm. Slender, parallel-sided; color brownish-piceus (fig. 1, <i>2</i>). Head finely punctuated and pubescent; interantennal space narrow and rather flat; eyes hemispherical, quite prominent and finely faceted. Antennae eleven segmented, slender and long, slightly longer than the elytral length, covered with semierect pubescence; antennomere proportions according to the formula: 7–3–4–4–4–4–4–4–4.5–5–8.5 (fig. 1, <i>2</i>). Pronotum slightly longer than wide and wider than a single elytron; apical margin widely convex anteriorly, partially concealing the head; sides slightly rounded, only slightly constricted near the base, moderately convex at the disk and showing a quite apparent transversal depression in the posterior third; surface irregularly sculptured in the anterior third, with round, small tubercles in the disk, and with small elongated tubercles in the posterior third transversal depression; pubescence formed by short semi-recumbent hairs evenly distributed (fig. 1, <i>2</i>). Legs short and robust covered with short recumbent pubescence; tarsi relatively long, nearly as long as tibiae; mesotarsi with tarsomere proportions according to the formula: 5–1.5–1.5–1–5. Scutellum triangular, as long as wide. Elytra subparallel and short, only slightly longer than twice the length of the pronotum; humeri prominent; elytral surface serially punctuated by elongated strial punctures, leaving an interstriae interval about twice wider as the width of the striae; pubescence formed by semirecumbent short setae inserted in the punctures (with a length similar to that of the puncture) and erect and moderately long (somewhat longer than those of the punctures) setae inserted in the intervals (fig. 1, <i>2</i>). D i a g n o s t i c c h a r a c t e r s. <i>S. brevipennis</i> is similar to the previously known species, <i>S. bukejsi</i> and <i>S. sucini</i> in having the same general structure of the prothorax, but differing from these species in having much shorter elytra, with a proportion length of the pronotum (LP)/length of the elytra (LE) = 2.1. This clearly differs from the proportion found in <i>S. sucini</i> (LE/LP = 2.7), in <i>S. bukejsi</i> (LE/LP = 2.6, according to measurement made on the pictures sent by V. Alekseev) and in <i>S. rovnoensis</i>, described above, where LE/LP = 3.0. E t y m o l o g y. The specific name refers to the shortness of the elytra, which is the most typical feature of the new species.
