New faunistical and taxonomic data on oribatid mites (Acari: Oribatida) of Taiwan

Résumé

The present study is based on oribatid mite material collected in Taiwan in 2017-2019. A list of identified taxa, including 141 species/subspecies from 88 genera and 47 families is provided; of these, 36 species/subspecies, 13 genera and five families are recorded for the first time in the Taiwan fauna, and eight species and one genus are recorded for the first time in the Oriental region. Two new species are described. Tyrphonothrus nivnu n. sp. (description based on adult) is similar to Tyrphonothrus altissimus (Piffl, 1971), T. cajamarcensis (Hammer, 1961) and T. wallworki (Starý and Block, 1995) in general morphological traits (notogastral ridges developed; tridactylous legs; notogastral setae e 2 , h 1 , h 2 , and p 2 long, setiform, with attenuate tip, other setae of medium length, setiform; high number of genital setae; absence of notogastral ornamentation; and comparatively large body size), but differs from these listed species by the barbed notogastral setae and comparatively long notogastral setae c 1 ,c 2 , c 3 , and e 1. Jacotella puyuma n. sp. (description based on adult and tritonymph) is similar to Jacotella neonominata Subías, 2004 in general morphological traits (centrodorsal notogastral part with two longitudinal ridges, posteriorly fused, each ridge with two lateral transverse branches; absence of notogastral ornamentation; notogastral seta h 1 distinctly longer than other notogastral setae), but differs from the latter by the narrowly elongate bothridial head, flagellate notogastral setae h 1 and p 1 , the length of notogastral setae, and the absence of additional longitudinal ridges connected lateral branches of median ridges (in adult); and by the long gastronotic seta h 1 similar in length to bothridial seta, seta h 2 similar to h 3 and lp and seta dm clearly longer than da on larval exuvium (in tritonymph).
