Abstract

TheAustrelatus papuensisgroup is the second species group of the New Guinean representatives of the recently described genusAustrelatusShaverdo et al., 2023. The group is mainly defined by distinct scale- and/or spinula-like surface structures of the dorsal sclerite of the median lobe. The species group already contains four described species and 42 new species and one subspecies treated here:Austrelatus aiyurensissp. nov.,A. asteiossp. nov.,A. bewaniensissp. nov.,A. bosaviensissp. nov.,A. bundunensissp. nov.,A. centralensissp. nov.,A. craterensissp. nov.,A. decorissp. nov.,A. dekaisp. nov.,A. epicharissp. nov.,A. flavocapitatussp. nov.,A. fuscussp. nov.,A. herzogensissp. nov.,A. inconstanssp. nov.,A. iriatoisp. nov.,A. kalibumisp. nov.,A. kebarensissp. nov.,A. kokodensissp. nov.,A. leptossp. nov.,A. lolokisp. nov.,A. lopintolensissp. nov.,A. madangensissp. nov.,A. maindaisp. nov.,A. mamberamosp. nov.,A. mianminensissp. nov.,A. miltokarenossp. nov.,A. noiadisp. nov.,A. normanbyensissp. nov.,A. ohusp. nov.,A. posmanisp. nov.,A. procerussp. nov.,A. pseudogestroisp. nov.,A. pseudomianminensissp. nov.,A. robustussp. nov.,A. sarartisp. nov.,A. sumokedisp. nov.,A. wanangensissp. nov.,A. wasiorensissp. nov.,A. wasurensissp. nov.,A. weigelisp. nov.,A. yamurensissp. nov.,A. yeretuarsp. nov.,A. xanthocephalus nabirensisssp. nov.A checklist and identification key to New Guinean species of the group are provided and important diagnostic characters are illustrated. Data on the species distributions and habiat preferences are given.
