03EE87E2FFF8FF850FF42CEC566CFDE7.taxon	discussion	Remarks Idiozetes schusteri sp. n. differs from the other species of the genus in combination of the following morphological traits: sexually dimorphic (males smaller and with two large tubercles in posterior part of notogaster) ; tutoria fused dorsally on prodorsum forming bidentate structure ; nine pairs of notogastral setae (c, la, lm, h 1 – h 3, p 1 – p 3) ; five pairs of notogastral saccules ; eight pairs of genital setae ; monodactylous. Distinctive characters of the new species from the other species of the genus Idiozetes can be found in the identification key below.	en	ErmilovK, Sergey G., SalavatulinK, Vladimir M.

03EE87E2FFFCFF840FF42E11508DFD10.taxon	distribution	Distribution and habitat of Idiozetes Species of Idiozetes are collectively known from the Oriental region, Japan, New Guinea, and Madagascar (Subías 2022, unpublished online version 2024). Idiozetes erectus has been described from Malaysia (without habitat ; Aoki 1976) ; later, the species has been recorded from Japan, Taiwan, China (in forests or without habitat ; Aoki 1987 ; Wang et al. 2003). Idiozetes javensis was found from Java (in forest with ferns, Zingiber sp., shrubs, dead tunks, mosses, dead leaves, debris ; Hammer 1979) ; later, the species has been reported from Taiwan (without habitat ; Wang et al. 2003) and Vietnam (mostly, in litter, soil and leaf litter in tropical forests ; also, in epiphytic roots of trees ; sugarcane litter and rhizosphere in sugarcane field ; decaying pine cone etc. ; Corpuz-Raros and Ermilov 2020). Idiozetes hagenensis has been registered from New Guinea (without habitat ; Colloff 2012). Idiozetes malgache has been collected from Madagascar (in decaying plant debris in humid, coastal and mid-altitude sclerophyllous forests ; Fernández et al. 2010). The new species (I. schusteri) has been recorded from Vietnam (in litter, tree bark and canopy branches in tropical forest ; data of this paper). According to the summarized data, representatives of Idiozetes inhabit mostly forests in tropical and subtropical zones preferring soil-litter but can live in different microhabitats including arboreal and ground substrata.	en	ErmilovK, Sergey G., SalavatulinK, Vladimir M.
