Zoraptera
No full text18 Zoraptera Tarsi are twosegmented with strongly shortened basitarsus. A strong, curved bristle is present between the paired claws. Specific adhesive structures are absent.Published as part of R. G. Beutel & S. N.

Ensifera
No full text14 Ensifera Tarsi are three or foursegmented. Proximal tarsomeres are equipped with euplantulae (Fig. 3h). An arolium is lacking.Published as part of R. G. Beutel & S. N.

Isoptera
No full text11 Isoptera Tarsi are fivesegmented in Mastotermes species, but foursegmented in other termites (Watson and Gay 1991). An arolium is present in alate adults. Euplantulae are not developed.Published as part of R. G. Beutel & S. N.

Lepidoptera 1758
No full text32 Lepidoptera An arolium is usually present. Hairy pulvilli are described for Epiphyas (Tortricidae; Nielsen and Common 1991: Fig. 41.3D) and Micropterix (Kristensen, personal communication). This condition is considered a groundplan feature of the order.Published as part of R. G. Beutel & S. N.

Archaeognatha
No full text4 Archaeognatha The tarsus is three or rarely twosegmented (Watson and Smith 1991). A welldefined, segmentlike pretarsus is not developed in archaeognathans and all following groups. The reduced pretarsus bears two simple claws. A median claw or empodium is not developed.Published as part of R. G. Beutel & S. N.

Strepsiptera
No full text29 Strepsiptera The full number of five tarsomeres and double claws are present in males of Mengenillidae, Mengeidae and Triozocerinae (Kinzelbach 1971). Tarsomeres are densely covered with hairs (Kinzelbach 1971). Broadened proximal tarsomeres, and loss of claws and the distal tarsomere, is characteristic of males of Stylopiformia (Kinzelbach 1971).Published as part of R. G. Beutel & S. N.

Psocoptera
No full text20 Psocoptera The tarsus is two or threesegmented (Weidner 1972). Euplantulae and arolium are lacking. A seta which is slightly extended distally (‘saugerartiger Pulvillus’; Weidner 1972) is present on the toothed or simple claws (Fig. 3j).Published as part of R. G. Beutel & S. N.

Hymenoptera
No full text30 Hymenoptera Four or threesegmented tarsi are found only in a few representatives of Hymenoptera (e.g. Chalcidoidea part., Platygasteridae, Trichogrammatidae; Naumann 1991). An arolium is generally present (Figs 2, 3a, 6F) and additional, specialized tarsal adhesive thorns in the nonapocritan groups (‘Symphyta’) (Figs 3i, 6A–C).Published as part of R. G. Beutel & S. N.
