All new species are authored by the taxonomist-in-charge, Alexander Riedel. Lectotypes are designated for the following names: Idotasia aequalis Pascoe, I. albidosparsa Lea, I. evanida Pascoe, I. laeta Lea, I. rostralis Lea, I. sculptirostris Lea, I. squamosa Lea. A new combination of the name Idotasia striatipennis Lea is proposed: Trigonopterus striatipennis (Lea), comb. n.. A key to the species is provided. Australian Trigonopterus occur in coastal Queensland, narrowly crossing into New South Wales. The southern parts of the range are inhabited by species found on foliage. A rich fauna of 19 edaphic species inhabiting the leaf litter of tropical forests is reported for the first time from the Australian Wet Tropics

Material examined. Holotype, female: PAPUA NEW GUINEA, Morobe Prov., Aseki, 1000–1300 m, leg. A. Riedel, 19.X. 1992 (SMNK) [pinned through right elytron; genitalia in glycerol in microvial attached to pin; left ala cut at base, on cardboard attached to pin; left metatarsus broken and glued separately]. Paratypes: PAPUA NEW GUINEA, Morobe Prov.: 1 female, Aseki, V. 1990 (TPCJ); 1 female, Aseki – Kabuanga, IV. 1996 (TPCJ); 1 female Aseki, II. 1972, leg. H. Ohlmus (ANIC). Distribution. Only known from Aseki, a village in Morobe Province (Papua New Guinea). Etymology. This epithet is based on the Latin adjective mimicus (imitative) and refers to the close resemblance with E. euphrosyne, possibly caused by a mimicry effect. Notes. This species appears to be closely related to the members of the schoenherrii -group of Riedel (2002), based on the dorsally furrowed rostrum and the structure of the female genitalia (basally thickened ductus spermathecae, dorsally extended hemisternite apex), although its coloration is very different. The genital structure of the superficially similar E. euphrosyne, on the contrary, agrees with that of the loriae - group (Figs. 14, 17, 20).Published as part of Riedel, Alexander, 2010, Two new species of Eupholus Boisduval (Coleoptera, Curculionidae, Entiminae), with observations on coloured cuticular exudates in weevils, pp. 23-34 in Zootaxa 2338 on pages 26-29, DOI: 10.5281/zenodo.27551

Papua New Guinea: 1 ex, Fly River. Distribution. West Papua: Cyclops Mts., Papua New Guinea: Fly River. Etymology. This epithet is based on the Latin adjective mimicus, -a, -um (acting, imitating) and refers to the superficial resemblance of its habitus and color pattern with Pantiala illusa Pascoe and Trigonopterus oblongus (Pascoe). Notes. One paralectotype of Pantiala illusa Pascoe is designated holotype and another one paratype of this new species.Published as part of Riedel, Alexander, 2017, The weevil genera Nyphaeba Pascoe and Pantiala Pascoe and the problems of an unstable nomenclature in orphaned taxa, pp. 377-389 in Zootaxa 4244 (3) on page 382, DOI: 10.11646/zootaxa.4244.3.6, http://zenodo.org/record/42873

Etymological note This species is named in honor of the late J. Sedlacek. Many specimens used in my studies on Papuan Euops were collected by him. With his ®eld work in New Guinea, both as a collector for the B. P. Bishop museum and on private expeditions, he has provided a most signi®cant resource for entomological research within this region. Biological note The females collected in Jiwika and in Bilogay presumably belonging to this species were found on N. starkenborghi or a similar species of Nothofagus.Published as part of Riedel, Alexander, 2001, The pygmaeus-group of Euops Schoenherr (Coleoptera, Curculionoidea, Attelabidae), weevils associated with Nothofagus in New Guinea, pp. 1173-1237 in Journal of Natural History 35 (8) on pages 1214-1217, DOI: 10.1080/00222930152434481, http://zenodo.org/record/527719
