Identification & Distribution

All adult viviparae of Tinocallis saltans are winged. Alatae (see picture below) are orange-yellow to pale yellow, with a brown head and thorax. The antennal segment apices are dark. The antennae are 0.8-0.9 times as long as the body, with the terminal process about 0.9 times the length of the base of antennal segment VI (cf. Tinocallis platani, which has the terminal process about 0.2 times the base of antennal segment VI). Antennal segment III bears 12-15 narrow elliptical secondary rhinaria. The apical rostral segment is about equal to, or shorter than, the length of the second hind tarsal segment. The pronotum has two pairs of finger-like spinal processes (cf. Tinocallis platani, Tinocallis zelkowae & Tinocallis ulmifolii, which have no processes on the pronotum). The mesonotum also has one pair of dark processes. The distal branches of the media of the forewing are bordered with fuscous, and there is also a patch of fuscous at the end of wing vein Cu1b. On the abdomen, tergites I and II each have a pair of finger-like pale processes, and tergite IV has a pair of smaller finger-like processes; other segments have dark wart-like hairy dorsal tubercles and marginal tubercles. The abdomen has dark spinal sclerites on tergites III-VIII and dark marginal sclerites on tergites I and V (cf. Tinocallis takachihoensis which has no dark markings on the dorsal abdomen). The stump-shaped siphunculi are dusky, and the cauda is knobbed.

The alatoid nymph (not pictured) has dorsal body setae set on dark sclerotic processes, as does the ovipara.

Tinocallis saltans are mainly found on elm (Ulmus spp.), but they have also been recorded from Zelkova serrata in Hungary. The species is monoecious holocyclic - fundatrices have been found in April and oviparae and alate males in October. It is found in Spain, Italy, eastern Europe (Hungary, Romania) and central and east Asia from Iran to Korea and China, and it has been introduced into North and South America (see Jensen in AphidTrek).


Other aphids on the same host

Tinocallis saltans has been recorded on 8 species of elm (Ulmus androssowi, Ulmus glabra, Ulmus japonica, Ulmus laevis, Ulmus minor, Ulmus parvifolia, Ulmus procera, Ulmus pumila).


We are grateful to Andrew Jensen for making his picture available for use under creative commons licences.

We have used the keys and species accounts of Richards (1967), Heie (1980-1995) and Quednau (2001) along with information from Roger Blackman & Victor Eastop in Aphids on Worlds Plants. We fully acknowledge these authors and those listed in the reference sections as the source for the (summarized) taxonomic information we have presented. Any errors in identification or information are ours alone, and we would be very grateful for any corrections. For assistance on the terms used for aphid morphology we suggest the figure provided by Blackman & Eastop (2006).
