Aulacothrips Hood, 1952 is a remarkable South American genus of ectoparasitic thrips which feed on gregarious ant-tended hemipterans (Hemiptera: Auchenorrhyncha). Here we describe two new species of this genus infesting membracid treehoppers in Colombia and Brazilian Amazon, and provide a key to the five Aulacothrips spp. now recognised. Aulacothrips levinotus n. sp. is unique in having pronotum with only two pairs of major setae; and Aulacothrips tenuis n. sp. has unusually long abdominal… 

Predators of leaf-feeding mites, Scolothrips (Thysanoptera: Thripidae), in Iran with first description of the female of Scolothrips tenuipennis

A predatory species Scolothrips tenuipennis is reported for the first time from Iran on the basis of female specimens collected on the grass Cynodon dactylon, and the female sex of the species is

Phylogenetic Analysis of the New World Family Heterothripidae (Thysanoptera, Terebrantia) based on Morphological and Molecular Evidence

It is concluded that additional morphological and molecular data would be desirable before revising the classification of Heterothripidae, because of the uncertainty in the monophyly of this group.

Ectoparasitic thrips affect the behaviour of their aetalionid treehopper hosts

The results suggest that thrips parasitism constitutes an important selective force for hemipterans and that its effects can influence host individuals, the aggregation and potentially the mutualistic interaction with ants.

The tortoise caterpillar: carnivory and armoured larval morphology of the metalmark butterfly Pachythone xanthe (Lepidoptera: Riodinidae)

The natural history and morphology of the later instars and pupa of the metalmark butterfly Pachythone xanthe H. Bates are described and illustrated for the first time. The caterpillars are myrmeco...

Thysanoptera of Bulgaria

The present checklist includes data on the species composition, geographic distribution and feeding preferences of thrips species in Bulgaria, and an evaluation of the biodiversity of Thysanoptera and the extent to which each region of the country has been studied.



A new ectoparasitic Aulacothrips (Thysanoptera: Heterothripidae) from Amazon rainforest and the significance of variation in antennal sensoria.

Aulacothrips amazonicus sp.n. is described from Northern Brazil, with larvae and adults ectoparasitic on ant-tended Membracidae (Hemiptera) on Solanum shrubs. This new taxon differs from its

Ectoparasitism and phoresy in Thysanoptera: the case of Aulacothrips dictyotus (Heterothripidae) in the Neotropical savanna

A unique case of an ectoparasite species, Aulacothrips dictyotus Hood (Heterothripidae), which infests and also uses as dispersal vector (phoresy behaviour) the hemipteran Enchenopa brasiliensis (Membracidae).

A new Brazilian species of Heterothrips (Insecta: Thysanoptera) co-existing with ants in the flowers of Peixotoa tomentosa (Malpighiaceae)

Heterothrips peixotoa Del-Claro, Marullo and Mound is described as new, and lives in the flowers of a malpighiaceous shrub in Brazilian cerrado, where some large ants are unable to penetrate this cavity, other ants are small enough to enter the space between the petals and sepals, and this leads to a reduction in thrips numbers.

Two ways to be a myrmecophilous butterfly: natural history and comparative immature‐stage morphology of two species of Theope (Lepidoptera: Riodinidae)

Differences in the degree of specificity in the ant–plant interactions may have an important role in the evolution of host-plant use in Theope.

Competition, resources and the ant (Hymenoptera: Formicidae) mosaic: a comparison of upper and lower canopy

A combination of more costly patrolling conditions and less profitable resources, such as extra -floral nectaries and trophobionts, may be the most likely cause of this pattern of ant defensive behaviour in tropical forest canopies.

Ants that associate with Lycaeninae butterfly larvae: diversity, ecology and biogeography

Multiple regression analyses revealed that the number of Lycaeninae species associated with a particular ant genus in a facultatively mutualistic manner is largely determined by the ecological prevalence and geographical distribution, but does not correlate with species richness, of an ant genus.

Latitudinal effects on treehopper species richness (Hornoptera: Membracidae)

Abstract. 1. Membracid species richness declines with increasing latitude in the Western hemisphere but begins to increase again in temperate regions. In northern latitudes this transition occurs in
