The genus Erythraeus (Acari: Erythraeidae) from China with descriptions of two new species and a key to larval species of the genus worldwide

Abstract

Two new mite species, Erythraeus (Erythraeus) hubeiensis sp. nov. and E. (Zaracarus) hainanensis sp. nov., are described and illustrated based on larvae parasitizing insects (Hemiptera) in Hubei and Hainan Provinces, China. An updated key to larval species of the genus Erythraeus of the world is presented.

Two New Species and a New Combination of the Subfamily Erythraeinae Based on Larval Stage (Acari: Trombidiformes: Erythraeidae) from China

“…Figures were drawn with the aid of a drawing tube attached to a Nikon Eclipse Ni-E microscope. The terminology and abbreviations are adapted from Haitlinger and Saboori [ 9 ], Zhang and Goldarazena [ 10 ] and Xu et al [ 7 ]. Measurements are expressed in micrometers (μm).…”

“…The subgenus Erythraeus s. str. and the subgenus Zaracarus were described from adults or/and juveniles, respectively, the subgenus Parerythraeus was described from the active postlarval instars only [ 2 , 6 , 7 , 8 ]. Hitherto, seven species of the genus Erythraeus were described from China, one of them was based on active postlarval instars— Erythraeus ( Erythraeus ) jacoti Goosmann, 1925—while the other six species were based on their larval stage, four of which belong to subgenus Erythraeus — Er .…”

New association between the mite Erythraeus sp. (Acari: Prostigmata: Parasitengona) and the psyllid Russelliana adunca (Hemiptera: Psylloidea)

“…The mite was identified as larva belonging of the genus Erythraeus and it was not fit with larval species of the genus worldwide key (Xu et al, 2019). No information about this genus in Argentina is available, nonetheless we mention some features that will help in future identifications: Body 352:175; two pairs of eyes on each side, dorsal scutum rounded and finely dotted Parasitengona mites are parasites of insects and arachnids or, exceptionally, free living, while adults and deutonymphs are predators of small arthropods (Salmane & Mąkol, 2018).…”

“…Some parasitengone families (between them Erythraeidae) parasitize hemipterans of the Auchenorrhyncha, Heteroptera and Sternorrhyncha suborders (Stroiński et al, 2013). The genus Erythraeus Latreille comprises about 124 known species, with two Subgenera: Erythraeus Latreille and Zaracarus Southcott, mostly distributed in the old world, and in a few regions of the American continent (Peru, USA and Galapagos) (Mąkol & Wohltmann, 2012;Xu et al, 2019) (Haitlinger & Mehrnejad, 2017;Costa et al, 2019;Ouvrard, 2021).…”

These papers also include 1 new genus and 19 new species named after Katya.…”
