Four new species of Lorryia (Acari: Tydeidae) associated with Hevea brasiliensis Muell. Arg. (Euphorbiaceae) in Brazil

Abstract

Lorryia (Tydeinae) species are commonly found in surveys of rubber trees (Hevea brasiliensis) in Brazil, although only Lorryia formosa (Cooreman, 1958) has been formally reported from this host. In this study, we described Lorryia parvireticuli sp. nov., L. amazonensis sp. nov., L. fortistriata sp. nov., and L. virga sp. nov., associated with rubber trees from Brazil.

Lorryia (Acariformes, Tydeidae): The evolutionary plasticity of an enigmatic genus

“…This criterion was also rejected by Baker (1968: 986) who stated that the presence of a single claw was a "misinterpretation". In interpretation 2, the single specimen of Lorryia superba is supposed to be an abnormal individual (Kaźmierski, 1998: 301; Kaźmierski andSikora, 2008: 88) or is considered as such (Mondin et al, 2016: 474; Kaźmierski et al, 2018. The presence of a single claw was observed at most on 4 legs of the same mite which seems hardly compatible with the single claw noticed on all the legs, thus eight times, of L. superba.…”

“…Lastly, it is not recommended to base a genus with dozens of species on a unique specimen, in addition enigmatic and not available. Therefore, the synonymy Lorryia-Brachytydeus made by Akbari et al (2015) and Mondin et al (2016) is not accepted. The species assigned to the genus Lorryia and described after the world catalog of Silva et al (2016a) (namely L. amazonensis, L. buceroincerta, L. columbina, L. fortistriata, L. lusciniella, L. meliponarum, L. parvireticuli, L. pseudoplacita, L. sibiriensis, L. speciosa, L. tuttii, L. virga) are transferred to Brachytydeus.…”

“…This interpretation was advanced by Kaźmierski (1989Kaźmierski ( , 1998. The single specimen of Lorryia superba is supposed to be an abnormal individual (Kaźmierski, 1998: 301; Kaźmierski andSikora, 2008: 88) or is considered as such (Mondin et al, 2016: 474; Kaźmierski et al, 2018. In that context, Brachytydeus is considered as a junior synonym of Lorryia (Akbari et al, 2015; Mondin et al, 2016; Kaźmierski et al, 2018; Da-Costa et al, 2019.…”

“…(1) Lorryia formosa, the original combination used by many authors; (2) Brachytydeus formosa, subsequent combination used by Lorençon et al (2016) Klimov et al (2018: 106) for molecular data; (3) Brachytydeus formosus with the gender agreement adopted by Kaźmierski (2008: 363) and Mondin et al (2015); (4) Tydeus formosus, with the gender agreement addressed by Flechtmann (1987) and Fenilli and Flechtmann (1990: 244); and (5) Tydeus formosa by Schiess (1981: 90), Nucifora (1984: 140-141), Prota et al (1984: 151) and Vacante and Nucifora (1986: 181).…”

Contribution to the fauna of Tydeidae (Acari: Prostigmata) from Western Siberia, Russia

“…In Russia, it was recorded in European part (Kuznetsov and Petrov 1984). Mondin et al (2016) consider L. reticulata as suspected junior synonym of L. superba (type species of Lorryia) and Kaźmierski et al (2018) consider L. reticulata as a junior synonym of L. superba. However, described the history of L. superba and noted that type specimen of this species is lost.…”
