The taxonomic reasons for regarding Lispe draperi Séguy, 1933, sp. rev., as a valid species instead of a synonym of Lispe tentaculata (De Geer, 1776) and for treating Lispe quaerens Villeneuve, 1936, syn. n., as a junior synonym of Lispe sericipalpis Stein, 1904 are given. A revised key for the Palaearctic members of the Lispe tentaculata species-group is given. Data on ecology, distribution and feeding preferences are provided.

The Lispe tentaculata species-group was proposed by
Currently eight species are placed in the Lispe tentaculata species-group, six of which are present in the Palaearctic region. The taxonomic status of Lispe alpinicola Zhong, Wu & Fan, 1981 has not yet been settled (see below). Lispe sericipalpis Stein, 1904 and Lispe orientalis Wiedemann, 1824 are also distributed in the Oriental region. Lispe tentaculata (De Geer, 1776) is recorded from the very north of the Oriental region and widespread in Nearctic. Two more species of this group are found in the Nearctic region.
Material and methodsThe majority of the specimens studied are in the Zoological Museum of Moscow University (not indicated in text). Other material is in Natural History Museum, London (BMNH), Zoological Institute, St Petersburg (ZIN), Zoölogisch Museum, Universiteit van Amsterdam (ZMAN).
The following abbreviations for morphological structures are used: f1, t1, f2, t2, f3, t3 = fore-, mid-, hind- femur or tibia; ac = acrostichal setae; dc = dorsocentral setae; a, p, d, v = anterior, posterior, dorsal, ventral seta(e); prst – presutural, post - postsutural.
Here I suggest a new abbreviation for the tarsi as tar followed by a pair of digits separated by a hyphen: the first digit (1 to 3) gives the leg number and the second digit (1 to 5) the number of the tarsal segment. For example, tar1-4 = 4-th segment of fore tarsus; tar3-1 = hind basitarsus.

Lispe sericipalpis Stein, male lectotype (designated by Pont, 1970). Photo by Joke van Erkelens.
Male. Ground colour black. Pollinosity grey, but may be yellowish-grey. Palpus black(ish), but becoming brown in old specimens. Fronto-orbital plate and parafacial whitish, rarely yellowish. Scutum with 3 brown vittae along ac and dc rows, submedian (dc) vittae sometimes almost indistinct. dc 2(1) + 4 (rarely 3), as: presutural: weak to hardly distinct, medium; postsutural: weak, weak, strong, strong. Presutural ac in 4–5 irregular rows. Legs dark. f2 with several (2–7) fine pv-setae in basal 1/3, the longest one (1.5 times as long as femoral width) at base. f3 at base with long (1.5–2 times as long as femoral width) and fine characteristic seta in v-pv position. Other setae on f3 variable: several av-setae present in apical third or slightly more, 1–3 among them longer, from as long as femoral width to twice as long; pv row may consist of 7–8 setae of which 2–3 are as long as femoral width, or may be reduced to 1–2 hardly distinct pv at base; sometimes chaetotaxy of f3 differs on right and left legs of the same specimen. Abdomen whitish-grey to yellowish-grey dusted, with paired L-shaped, more or less extensive dark spots on tergites 3 to 5, divided by dusted median vitta. Female differs from male as follows: parafacial more often yellowish; dc 1+4(3), anterior prst dc always absent; v-pv seta at base of f3 shorter to reduced; other ventral setae on f2 and f3 shorter or reduced.

Lispe tentaculata has a variable t3 chaetotaxy: besides the normal strong ad and short pd setae, an additional seta just below the strong ad but in a more a-position is often present and sometimes a second strong ad and a short pd may also be present. About 5% of females have a male-like scutum: with only 3 strong post dc and without a pruinose patch on the scutum.
Lispe tentaculata is a very common species across its natural habitat. The northernmost specimens were collected near Murmansk (forest-tundra at 69°N) and Vorkuta (tundra at 67.5°N), where this species was found on boulders on river banks and was the only Lispe species recorded at these places. In southern Turkey at 36°N Lispe tentaculata was common again on boulders in streams and, in springtime, at various muddy places such as temporary pools. In temperate conditions of the East European Plain Lispe tentaculata is absent from small forest streams and is infrequent on the sandy banks of big rivers but is common on the mud ponds and small lakes. Both in temperate and southern habitats Lispe tentaculata distinctly avoids a salty mud where it is replaced by species from the Lispe caesia-group and the Lispe palposa-group. Lispe tentaculata is common in high mountain areas where it prefers boulders along the shores of mountain lakes; the series from Gorno-Badakhshan in Tajikistan was collected at 3800 m asl.
Lispe draperi was observed in Morocco in late March and seems to have an ecology similar to Lispe tentaculata.
Lispe consanguinea clearly prefers narrow sandy bands along the banks of big rivers. In this habitat Lispe consanguinea is the dominant species in the temperate zone, whereas Lispe tentaculata is uncommon. I had never collected Lispe consanguinea in localities north of the Arctic Circle, but on sandy banks of the Vychegda River at 61.3°N, 46.9°E this species was very common. The most southern records are Tajikistan (Dushanbe env., 1 specimen) and N. Turkey (2 specimens among numerous Lispe tentaculata).
Lispe sericipalpis (Fig. 5.1) may be found on boulders on the banks of rapid streams together with Lispe tentaculata. In N. Turkey this species is uncommon, whilst in S. Turkey Lispe sericipalpis is absent in spring time (late April), but becomes about as common as Lispe tentaculata in September. In Myanmar Lispe sericipalpis was absent in tree-shaded parts of streams, but was found in sunny sites at altitudes of 1100–1300 m asl.
1 Lispe sericipalpis Stein, male (Turkey, Antalya) 2 Lispe orientalis Wiedemann, male (Azerbaijan).
The ecology of Lispe orientalis (Fig. 5.2) is rather unusual: it is a species of dirty, organically-polluted water. Lispe orientalis was collected in Krasnodarsky Kray (Russia) and Antalya prov. (Turkey) around drinking bowls at pools polluted by cattle dung, in Tajikistan (Farkhor) at a very dirty irrigation ditch inside the town and at pools around this ditch polluted by refuse and even carrion, and in Hatay prov. (Turkey) at a strongly dung-polluted pool under a cattle shed.
In Azerbaijan, in late October, I observed Lispe orientalis during cold and bad weather, when it rained every day and usually all day long. In such conditions most flies appeared only after several hours without rain, while during the rain the only active dipteran was Lispe orientalis which hunted Diptera larvae on a wet chicken dunghill. It seems that Lispe orientalis has adapted to endure the rain and to keep on hunting because the larvae have to move up to the surface of the chicken manure and thus the prey becomes more accessible to the predator. In contrast to the related Lispe sericipalpis, Lispe orientalis prefers stagnant water. Only once near Çivlek (Turkey, Hatay prov.), I found Lispe orientalis by a rapid stream but shortly afterwards found a cattle shed in 50 metres upstream, which explained the presence of this species.
Lispe orientalis was regarded as an Oriental species, but the records listed above show that it is widespread in the South Palearctic and rather uncommon in the Oriental region where, for example, my dedicated Lispe collecting in Thailand made over several years has yielded only a single specimen of Lispe orientalis. The record from European Russia (Krasnodarsky Kray, vicinity of Sochi) is the northernmost one (43.4°N) and the first record for Europe, but I suspect that Lispe orientalis may be found in other European countries, being overlooked due to its omission from the keys for European Lispe.
FeedingIt is well known that all Lispe are predators (e.g.
Lispe draperi Séguy, male feeding on a dead Corixidae bug (Morocco, Essaouira).
I thank Adrian Pont (Oxford) for his invaluable help. Due to the kind help of Dutch colleagues Ben Brugge, Joke van Erkelens and Gerard Pennards (Amsterdam) I was able to examine type material of Lispe sericipalpis. I thank Oleg Kosterin (Novosibirsk) and Paul Beuk (Maastricht) who suggested several useful corrections.
