“…For example, the mean width of the maxillary stylet of M. hardyi (body length -15 mm) is 13.9± 0.2 µm and the mean width of the ingested spore of D. thripsita is 10.9± 0.3 µm. This observation along with the spores extracted from the gut confirmed the spore feeding habit of M. hardyi (Tree et al, 2010;Eow et al, 2011). This example serves well to illustrate mycophagous habit of the other Idolothripinae.…”

“…ThripsWiki (2021) lists 6312 extant taxa under 785 genera and 175 extinct taxa under 65 genera (Mound and Vesmanis, 2021), of which a little >50% utilize fungi as their source of food (Morse and Hoddle, 2006;Mound, 2005). Among the mycophagous Thysanoptera, >700 spore-feeding idolothripines are known worldwide (Eow et al, 2011). In the Neotropics, mycophagous Thysanoptera occupy 50% of the total numbers of thrips known (Mound, 2002).…”

“…Considering that in the context of Phlaeothripidae and fungi, the mutualism between them can be described in terms of dispersal and nutrition of the involved thrips. Nearly 2100 species of the Phlaeothripidae feed on fungal hyphae and spores (Dang et al, 2014;Eow et al, 2011). Some evidences also exist to indicate that the Thysanoptera act as mechanical vectors and disseminate fungal spores on plants (Ananthakrishnan, 1980;1993).…”

Mycophagous Phlaeothripidae (Thysanoptera: Tubulifera:) are recognizable as (a) fungal-hyphae-feeding mycetophagous Phlaeothripinae, living on fungi that infest dry twigs and (b) fungal-spore-feeding sporophagous Idolothripinae, usually present on leaf litter. In the Indian subcontinent, out of 765 species of known Thysanoptera, nearly 152 species in 66 genera fall within the mycophagous group of the Phlaeothripidae with 54 idolothripine and 98 phlaeothripine species. Taxonomic diversity of these species in bamboo- and oak-leaf litter and pine forests in the sub-Himalayan ecosystems of North-Eastern India are discussed in this article, along with the diversity that is apparent in their developmental patterns, thrips-plant-fungus association, and phenotypic plasticity, supplemented with a note on their ecological implications.

“…A very different habitat, leaf-litter that is often rather moist, seems to be favored by some spore-feeding species whereas others are probably associated with rather well drained leaf-litter. At ground level, specifically at the base of tussocks of grass, is another suite of Idolothripinae species (Eow et al 2011). Fungus-feeding thrips species commonly live in the relatively moist forest .…”

“…Most of the fungus-feeding thrips known from Iran have been collected from leaf litter rather than from dead branches, and this contrasts with the situation in more temperate countries (Mound et al 2018). In previous studies on fungus feeding Tubulifera (Dang et al 2014;Dang & Qiao 2013;Eow et al 2011;Mound & Palmer 1983), leaf litter is the most common habitat amongst this group of insects with moisture required for fungus to grow as food and thick layers of dead leaves and branches as a good shelter. However, the number of extracted specimens from…”

Six species, including four new species, are recognised from Australia in Bactrothrips, and Lasiothrips Moulton is synonymised with this genus. This group of spore-feeding thrips is widespread on dead leaves across the Old World tropics from Africa to Japan. The Australian species are mainly associated with dry fruiting capsules of Eucalyptus trees. Males usually have lateral tubercles on the abdomen, but no fore tarsal teeth, and the significance of this in sexual behaviour is noted.Of the 46 species listed in Bactrothrips, 34 are described from Africa or Madagascar, with most of these known from single individuals and thus no information on intraspecific variation. In this genus, an identification key is available only for the seven species known from Japan (Okajima, 2006). Among the African species there is considerable variation in the number and form of lateral tubercles on the abdomen of males. In different species these are present on one or more of segments V-VIII, their shape is either simple or bifurcate, and in a few species they are completely absent. Six genera have been erected for these variants, but these are now all placed as synonyms. A further complication is that three genera related to Bactrothrips have been distinguished because the pronotal epimeral sutures are complete rather than incomplete. Each of these three genera, Egchocephalothrips from New Caledonia, Cylindrothrips from Southwest Africa, and Lasiothrips from Australia, was based on a single specimen, and each of these specimens is slightly crushed. The apparently complete nature of the epimeral sutures is thus probably an artifact, with Lasiothrips here considered a synonym of Bactrothrips, and the condition of the epimeral sutures discussed below under B. perplexus. A third character used for distinguishing taxa in the subtribe Idolothripina is the position of the maxillary stylets within the head (Mound & Palmer, 1983). Nine species are placed in either Bacillothrips or Megalothrips because the stylets are deeply retracted into the head and very close together medially. In contrast, six species with the stylets deeply retracted but well separated within the head are placed in Megathrips, whereas species placed in Bactrothrips, Idolothrips and Meiothrips have the stylets widely separated and low in the head. The six species here recorded from Australia exhibit the full range of states of all three of the characters mentioned above, thus throwing further doubt on the current generic classification.
