Colour photographs and drawings were made with a Nikon Eclipse E 600 microscope and by the computer program NIS Elements, Ver. 4. 10. Body length was measured from the apex of head to the apex of fore wing; body width, across the maximal width; pronotum length, along midline; pronotum width, across the broadest part at its posterior angles; hemelytron length, from the base to the apex of anterior margin; hemelytron width, at maximal width of the hemelytron. All measurements are in millimeters (mm).
Distinguished from the other extinct hallodapine genus
Holotype: female, Baltic amber, PIN RAS 964/1310; light yellowish middle-sized piece of amber (28 × 12 mm) of irregular shape. One dipteran syninclusion. The holotype is deposited in the collection of the Borissyak Paleontological Institute Russian Academy of Sciences (Arthropod Laboratory), Moscow.
Readily recognized among the other species of
Female. Macropterous. Body length up to 7 mm, 2.8 times as long as wide. Dorsal surface almost smooth, impunctate. Ground colour light brown, almost yellow; mesoscutum and scutellum brown, hemelytra with one pale transverse fascia just posterior to scutellum, apical part of cuneus dark; hemelytral membrane dark, hyaline, slightly crumpled (Figs
The species epithet (Latin “antennatus”) refers to the unusual flattened and widened the second antennal segment.
1 | Body strongly elongate, more than 4 times as long as wide; dorsum of surface rippled. Head slightly more than 1.5 times as broad as long. Pronotum length and width subequal; pronotal calli indistinct. Head, pronotum and cuneus pale |
|
– | Body less than 4 times as long as wide; dorsum smooth, impunctate. Head almost twice as broad as long. Pronotum 1.2–1.3 times wider than long; calli weakly developed. Head, pronotum and part of cuneus dark |
|
2 | Second antennal segment flattened and considerably widened to apex, more than two times longer than 3rd; vertex with two slightly concave cavities; scutellum small, only twice long as mesoscutum length and less that one-third length of claval commissure |
|
– | Second antennal segment more slender, not expanded apically; less than twice as long as 3rd; vertex without cavities; scutellum large, ca. one-half length of claval commissure |
|
3 | Mesoscutum large, slightly more than one-half as long as scutellum; first tarsal segment of hind leg longest, second segment shortest |
|
– | Mesoscutum small, one-fifth as long as scutellum; first and third tarsal segments of hind legs longest and almost equal in size |
|
4 | Pronotal collar less narrow, thickness not less than 0.15 mm; cuneus less that one-fourth length of corium; all pairs of legs almost wholly bare |
|
– | Pronotal collar more narrow, thickness 0.1 mm; cuneus ca. one-third length of corium; all pairs of legs are covered with very short, dense, adpressed setae |
