Eogyropsylla sedzimiri View in CoL sp. nov.
( Figs. 1–10 View FIGURES 1 – 6 View FIGURES 7 – 10 )
Diagnosis. Forewing relatively small, length of forewing 1.6 mm, width 0.7 mm; length of antenna 0.5 mm; pterostigma long, its length equal to half of forewing length; cell cu1 relatively short, with ratio length/height equal to 2; cell m1 with ratio length/height equal to 1.86.
Description. Length of body 1.5 mm. Head 0.55 mm wide more than twice wider than long along mid line, weakly declined from longitudinal body axis. Genal cones absent. Compound eyes bulging, subglobular, protruding laterally beyond the head outline. Vertex 0.2 mm long, 0.34 mm wide, with two symmetrical concavities in the middle portion, without median (coronal) suture. Anterior margin of vertex with deep median incision. No microsculpture nor any setae visible on vertex. Lateral ocelli well developed, placed posteriorly and laterally on the vertex. Antennae 10-segmented, 0.47 mm long; rhinaria not visible.
Thoracal tergites well visible. Pronotum narrow, 0.5 mm wide, 0.07mm long, with parallel anterior and posterior margins, slightly curved in the middle. Mesopraescutum 0.36 mm long, 0.12 mm wide, slightly curved in anterior portion. Mesoscutum 2.5 times broader than long (width 0.50 mm, length 0.20 mm); with lateral portions elongated forward. Mesoscutellum 0.16 mm wide, 0.093 mm long. Mesopostnotum situated behind the mesonotum at the dorsal side, covered by mesoscutellum, not visible, traceable as narrow strip running diagonally towards mesoepimeral sclerite. Metascutum narrow, with metascutellum broader, elevated over metascutum disc. Sclerites of metanotum (metascutum and metascutellum) well visible in dorsal aspect. Metapostnotum trapezoid, seems to be fused with first abdominal tergite.
Thoracal pleurites not visible (the piece of amber is very stout and not polished), thoracal sternites covered by legs, not visible.
Forewing hyaline, transparent, yellowish with darkened veins (coloration in amber); 1.5 mm long, 0.69 mm wide, with apical margin rounded. Pterostigma present, elongate, about a third forewing length. Cell cu1 short, length/ height ratio = 2, cell m1 with length/ height ratio = 1.86.
Hind wings well developed, hyaline and transparent; 1.07 mm long, 0.45 mm wide. Shape and position of veins R and M suggesting a type of hind wing venation with vein Cu1 separating from R+M+Cu1 stem proximal of forking of R+M into R and M. The point of separation of R and M veins is well visible, whereas the point of separation of vein Cu1 is not. Veins M and Cu1 are not in contact. Vein M is not forked. Cell cu1 on hind wing relatively small, with coefficient length/height 2.1.
Legs. Hind tibia with 5 darker spines at apex.
Abdomen clearly visible.
Female terminalia partly separated from abdomen. Female terminalia elongate, longer than high at base. Subgenital plate shorter than proctiger. Anus not visible on proctiger. Valvulae not visible.
Etymology. This species is named in honour of the late Professor Sędzimir Maciej Klimaszewski, one of the world’s eminent specialists in recent and fossil psyllids.
Stratigraphical range. Eocene, Baltic amber.
Material. Holotype. Female. Specimen number 1708, WK 1360, deposited in the Museum of Amber Inclusions, Department of Invertebrate Zoology, University of Gdańsk, Poland.
Condition of the specimen. The specimen is well preserved in a large clear piece of amber. Some details of head, antennae and legs are difficult to observe, because the amber is very stout, not polished.
