Sigmacallis pilosa Zhang from Populus in China perhaps belongs 
to the Mindaridae according to Zhang & Zhong (1981) although its 
pterostigma is rather short, not reaching to the tip of the wing. 
Lizerini is a tribe within the subfamily Drepanosiphinae, family 
Drepanosiphidae (Heie, 1980). Among its archaic characters is the 
presence of scent plaques (“pseudosensoria”) on all tibiae of the 
oviparous morph, not only the hind tibiae. The apterous morphs 
carry “chamois-horn-like” processes as the extinct Palaeosiphon 
hirsutum (Germar & Berendt) (the oviparous female of which also 
has scent plaques on all tibiae) from Baltic amber (Heie, 1967) and 
some recent representatives of various tribes of Drepanosiphinae, 
e.g. Eonaphis Quednau from Africa and Neuquenaphis Essig from 
South America. Until now 30 recent species of Lizerini have been 
described, 9 species of Lizerius and 21 species of Paoliella. Not all 
Lizerini have wings like Mindarus. The pterostigma does not quite 
reach the apex of the wing in Lizerius intermedius Quednau, L. 
costai Quednau and some others. Mindazerius dominicanus resem- 
bles L. cermelii Quednau (on Bougainvillea in Brazil) very much in 
respect to wing venation and some other characters. 
Summary 
The first fossil aphid from the Neotropics, Mindazerius domini- 
canus nov. gen., nov. sp., is described from Dominican Republic 
amber. It is placed in the tribe Lizerini of the family Drepanosiphi- 
dae (Aphidoidea) and shares characters with the genera Mindarus 
and Lizerius. Major features of the fossil include the long ptero- 
stigma of the fore wing the truncate siphunculi, long cauda and 
strongly thickened fore femora. Biological and zoogeographical 
implications, as well as affinities with both fossil and recent 
relatives, are presented. 
Key words: Aphid, Lizerini, Drepanosiphidae, Mindaridae, fossil,
