Calisiomorpha yuripopovi nov.sp. (Figs. 1-5, photos 1-2)

H o l o t y p e: Female in a piece of Burmese amber from " Kachin State " in Myanmar ( Burma) embedded in epoxyd resin (10x11x 6mm), legs and antennae complete, left fore wing spread laterally, pro-meso-and metasternum and sternites VII-VIII partly obscured. It is designated as holotype and labeled accordingly.

D e s c r i p t i o n: H e a d: Slightly wider than long (29/27); clypeus apically enlarged and rounded reaching apex of antennal segment II, surface granulate and medially depressed; antenniferous lobes long and acute, beset with conical tubercles; antennae 0.93x as long as width of head, segment I cylindrical, II tapering toward base, III shortest, IV fusiform and longest, apex pilose; length of antennal segments I/II/III/IV = 7/7/5/8; eyes subconical laterally produced; postocular lobes straightly converging posteriorly to constricted collar; vertex with longitudinal rows of tubercles, depressed between them; rostrum arising from an open atrium, reaching anterior margin of prosternum.

P r o n o t u m: 2.94x as wide as long (53/18), ring-like collar carinate and raised; areolate paranota widening anteriorly, lateral margins roundly converging anteriorly; disk with five carinae, the median one not exceeding posterior lobe, lateral and sublateral ones reaching collar; posterior margin carinate and concave.

S c u t e l l u m: Longer than wide (32/26), basal and lateral margins carinate, apex rounded; disk with a median carina which is bifurcate anteriorly.

H e m e l y t r a: Corium short, about as long as scutellum, truncate posteriorly; lateral margins expanded and angularly produced at a lower level over abdomen; membrane hyaline with three straight veins discernible.

A b d o m e n: Oval, lateral margin of connexival edge of deltg III-VII with a dorsal and vltg III-VII with a ventral row of four flat tubercles, the first and last one brown as the adjacent anterior and posterior margins of respective laterotergites, those inbetween are stramineous; number of tubercles is reduced to two on deltg and vltg II, increased to five in one row of two segments (V left, IV right); tergite VIII truncate posteriorly.

V e n t e r: Pro-, meso- and metasternum flat at middle, separated by transverse sutures; sternite VII split medially, vltg VII subtriangular; no metathoracic scent gland structures and no spiracles discernible with certainty.

L e g s: Femora fused to trochanters, moderately incrassate; tibiae cylindrical shorter than femora, tarsi two-segmented with long, apically enlarged pulvilli.

M e a s u r e m e n t s: Length 3.8mm; length of antennae 0.675mm; width of corium at angulate expansion 1.75mm; width of abdomen 1.82mm.

E t y m o l o g y: It is a great pleasure to dedicate this unique amber taxon to my dear friend and eminent paleontologist Yuri Popov (Paleontological Institute, Russian Academy of Sciences, Moscow) honouring and sharing the 80 th birthday earlier this year.
