We analysed pretarsal characters of 87 species of Leiodidae (including 10 cholevines and representatives of all tribes and ca. 60% of the genera of non‐cholevines), five species of Agyrtidae, and nine representatives of outgroup taxa (Hydraenidae, Staphylinidae, Hydrophilidae, and Histeridae) using scanning electron microscopy. We focused our observations on the architecture of the empodium (including the sclerites and associated setae), the shape and composition of the medial projection of the… 

The ‘twins’ and the ‘bachelor’, new potential synapomorphies inside the Cholevinae (Coleoptera: Leiodidae)

It is recognized (as a new synapomorphy for the tribe) that special, strong spines also appear at the apex of the first three or four tarsomeres of the Ptomaphagini, a tribe with a Holarctic-Neotropical-Oriental distribution.

The Near Eastern species of Leptodirini (from Armenia, Georgia, Iran, Israel, Lebanon, Southwestern Russia, Syria and Turkey) are reviewed and the genus Catopsinus (Motschulsky, 1868) is resurrected for four species previously placed in Bathysciola Jeannel, 1910, solving the long-term problem of the name “Bathysciol”.

To be biased or to be Neotropical: systematic reassessment of a megadiverse lineage of rove‐beetles (Philonthina, Staphylinini, Staphylininae)

A phylogenetic analysis of the subtribe Philonthina with focus on its NT lineage based on 132 morphological characters including 79 taxa from genera and/or species groups relevant to the study found that the NT lineage diversified into at least seven clades, each of which provides a framework for future taxonomic studies.

To be or not to be a tibial comb: A discussion on the (past) use of tibial armature in tribal/subtribal organization in Cholevinae (Coleoptera: Leiodidae)

A phylogenetic signal is found in an apical crown of tibial spines not interrupted at the outer spur, which seems to be an additional synapomorphy of Ptomaphagini, differing from the pattern in Eucatopini and remaining cholevines with anapical comb of spines, in which the comb is interrupted.

Pretarsus and distal margin of the terminal tarsomere as an unexplored character system for higher‐level classification in Cholevinae (Coleoptera, Leiodidae)

The data challenge the traditional view of a close proximity of Eucatopini and Ptomaphagini as well as a previously suggested synapomorphy of Leptodirini, and reinforce the monophyly of Ptomphagini.

The pretarsus in Chalcidoidea (Hymenoptera Parasitica): functional morphology and possible phylogenetic implications

The structure of the pretarsus of chalcid wasps (Hymenoptera: Chalcidoidea) was examined with light and scanning electron microscopy and characters may be correlated with differences in body size that characterize the different lineages rather than being phylogenetically important.

Morphology and evolution of the tarsal plantulae in Hymenoptera (Insecta), focussing on the basal lineages

The morphology of the plantulae (= tarsal pulvilli = plantar lobes), structures attached to the underside of the tarsus in Hymenoptera, was examined in 55 genera from all 14 families of the basal lineages and a few species of Apocrita using scanning electron microscopy.

Structure of the tarsi in some stenus species (coleoptera, staphylinidae): External morphology, ultrastructure, and tarsal secretion

Gas chromatography and infrared spectroscopy revealed that the lipid fraction of the secretion is a mixture of unsaturated fatty acid glycerides and aliphatic hydrocarbons whose spectra are similar to those of extractions of the superficial lipid coating of the body surface.

Evolution of attachment structures in the highly diverse Acercaria (Hexapoda)

The monophyly of the entire lineage and of the major subgroups Psocodea, Phthiraptera, and Hemiptera is confirmed and the monophys of Auchenorrhycha and a sister‐group relationship between Thysanoptera and HemIPtera is supported.

Surface ultrastructure and evolution of tarsal attachment structures in Plecoptera (Arthropoda: Hexapoda)

The presence of hairy euplantulae as part of the stonefly ground pattern contradicts the recent view that stoneflies lack pad-like euplulae and that the ancestral condition for tarsomeres 1 and 2 may be a narrow median longitudinal unsclerotised band such as that found in representatives of the Austroperlidae.

Phylogeny of the Coleoptera Based on Morphological Characters of Adults and Larvae

Abstract. In order to infer phylogenetic relationships within the extraordinarily speciesrich order Coleoptera, a cladistic analysis is performed, in which 516 adult and larval morphological

A Revised Interpretation of the Evolution of Attachment Structures in Hexapoda with Special Emphasis on Mantophasmatodea

Characters of hexapod attachment structures were analysed cladistically together with 110 additional morphological characters of immatures and adults. The results suggest the monophyly of Hexapoda,
