Material.— Female, NHMD 38971 [alternative ZMUC 902144 View Materials ], Danish amber; western coast of Denmark; Lutetian– Priabonian , Eocene , collected by C. V. Henningsen , 1.7.1966, deposited in Amber Collection in Natural History Museum of Denmark. Imago of whitefly is included in clear light yellowish and small sized piece of amber in flat cube shape (10×8× 3 mm). Specimen located near edges of amber, which significantly hindered observation and taking pictures .

Description.—Measurements: Table 1. Head invisible ( Fig. 9A View Fig 4 View Fig , A 8 View Fig ). Antennae seven-segmented ( Fig. 9A View Fig 3 View Fig , A 5 View Fig ). Scapus not visible, pedicel large and massive, tapering towards apex, at least 1.7 times as long as wide. Third antennomere the longest, about 4 times longer than 4 th. Fourth and 6 th antennomeres equal in size, antennomere 5 th the same length as 7 th, about 1.2 times longer than antennomeres 4 th and 6 th. Antennomere 7 th tapering towards apex.

Fore wing widening apicad, the widest in about 3/4 of the length, about 2.1 times as long as wide ( Fig. 9A View Fig 1 View Fig , A 4 View Fig , A 6 View Fig , A 7 View Fig , A 8 View Fig ). Costal vein rounded at the base, further arcuate, anteroapical angle arcuate, apical margin arched, posteroapical angle arcuate. Posterior margin rounded at the base, then straight. Several relatively long setae visible on the apical edge of the fore wing. Common stem Sc+R+CuA short and thick ( Fig. 9A View Fig 1 View Fig , A 4 View Fig ). Branch Sc+R arched, directed towards the anteroapical angle, forked about half the length of the wing. Branch R1 ( Fig. 9A View Fig 1 View Fig , A 6 View Fig , A 8 View Fig ) weakly visible, slightly arched, not reaching the margin. Branch Rs slightly curved in the middle part, about 2.3 times longer than the branch R1, not reaching the margin. Vein CuA almost straight, slightly curved in the middle part, departing at an acute angle from the common stem Sc+R+CuA, almost parallel to the branch Rs, not reaching the margin ( Fig. 9A View Fig 1 View Fig , A 4 View Fig , A 8 View Fig ). Claval vein CuP straight, not reaching the margin ( Fig. 9A View Fig 1 View Fig , A 4 View Fig ). Hind wing widening apicad, the widest in about 2/3 of the wing length, at least 1.9 times as long as wide ( Fig. 9A View Fig 2 View Fig , A 4 View Fig , A 6 View Fig ). Anterior margin invisible, anteroapical angle arcuate, apical margin arched, posteroapical angle rounded, posteriori margin straight with a slight depression in the middle part. Branch Sc+R slightly curved in the middle, not reaching the margin.

Legs visible partly only ( Fig. 9A View Fig 6 View Fig ), thorax not visible ( Fig. 9A View Fig 4 View Fig , A 6 View Fig , A 8 View Fig ).

Abdomen visible fragmentarily, mainly in the distal part ( Fig. 9A View Fig 4 View Fig , A 8 View Fig ). Gender cannot be determined. Probably female due to characteristic triangular shape of apical part of the abdomen (visible from the lateral view) and the lack of claspers or aedeagus ( Fig. 9A View Fig 4 View Fig , A 8 View Fig ).
