Material. — Male, NHMD38970 [alternative ZMUC 902143 View Materials ], Danish amber; western coast of Denmark; Lutetian–Priabonian , Eocene , collected by C. V. Henningsen , 19.6.1964, deposited in Amber Collection in Natural History Museum of Denmark. Imago of whitefly is included in clear brownish and small piece of amber (7×5× 2 mm) of flat cube shape. Specimen located right on the surface of amber. The condition of some fragments of the dorsal side of the body suggests that they protruded beyond the piece of amber and decomposed .

Description.—Measurements: Table 1. Head from the dorsal side destroyed ( Fig. 8A View Fig 7 View Fig , A 8 View Fig , A 12). Compound eyes large and bulging, not divided with big and equal in size ommatidia ( Fig. 8A View Fig 9 View Fig , A 10 View Fig ). Lateral ocelli not visible. Antennae seven-segmented ( Fig. 8A View Fig 3 View Fig , A 7 View Fig , A 12). Scapus visible partially, relatively short with angular margins. Pedicel large and massive, wider at the apical part, about 2.4 times as long as wide. Third antennomere the longest, about 4 times longer than 4 th. Fourth antennomere the same length as 6 th, antennomeres 5 th and 7 th equal in size and slightly longer than antennomeres 4 th and 6 th, 7 th antennomere tapering apicad.

Thorax in dorsal view not preserved ( Fig. 8A View Fig 7 View Fig , A 8 View Fig ). Only a metascutellum is visible, with a lenticular median part and narrow lateral parts.

Fore wing only as an imprint on the amber surface ( Fig. 8A View Fig 1 View Fig , A 8 View Fig , A 9 View Fig ). The visible shape of the wing and a part of the branch Rs remained. The impressed fore wing widening apicad, the widest in about 3/4 of the length, about 2.2 times as long as wide. Costal vein imprint invisible at the base, further straight. Anteroapical angle arcuate, apical margin arched, posteroapical angle arcuate, posterior margin invisible at the base, further arcuate. Hind wing narrow at the base, widening apicad, the widest in about ⅘ of the length, about 2.4 times as long as wide ( Fig. 8A View Fig 2 View Fig , A 7 View Fig , A 8 View Fig , A 9 View Fig , A 11 View Fig ). Costal vein arcuate at the base, further almost straight, anteroapical angle arcuate, apical margin arched, posteroapical angle rounded, posterior margin arcuate. Branch Sc+R straight, not reaching margin.

Metaleg about 1.3 times longer than mesoleg ( Fig. 8A View Fig 4 View Fig , A 9 View Fig , A 10 View Fig , A 13). Metacoxa elongated, trochanters poorly visible. Metatibia about 1.2 times longer than metafemora. Tarsi two-segmented. Basimetatarsomere about 1.3 times longer than apical tarsomere. Claws relatively short and thin ( Fig. 8A View Fig 4 View Fig , A 13). Paronychium poorly visible, about half the length of the claw ( Fig. 8A View Fig 13). Metatibia and metatarsus covered with relatively evenly dispersed, fine seta ( Fig. 8A View Fig 4 View Fig , A 7 View Fig , A 9 View Fig , A 10 View Fig , A 13). Metafemora without seta. The tibial combs consist of 13 long and evenly distributed seta on the inner side of the metatibia ( Fig. 8A View Fig 4 View Fig , A 13).

Abdomen collapsed on the dorsal side ( Fig. 8A View Fig 7 View Fig , A 8 View Fig ), from the ventral side partly covered by a cloudy part of amber ( Fig. 8A View Fig 9 View Fig , A 10 View Fig , A 13). Abdomen relatively slim, strongly narrowed at the thorax, longer than the total length of the head and thorax. Pygofer slightly wider than its length in the midline, almost quadrangular in shape ( Fig. 8A View Fig 5 View Fig , A 13, A 6). Aedeagus bottle in shape at the base, then straight, with apical part not visible (hidden behind the claspers) ( Fig. 8A View Fig 5 View Fig , A 13, A 6). Claspers elongated and relatively wide, slightly narrowed distally, as long as the pygofer ( Fig. 8A View Fig 5 View Fig , A 13, A 6). The outer margin slightly arched, the inner margin with convexity in the middle. Claspers overlapping at the apical part and curved dorsad.
