Abstract and Figures

Four new species of the genera Dryophthoroides Roelofs, 1879 and Nephius Pascoe, 1885 from the tribe Stromboscerini of the subfamily Dryophthorinae are described and illustrated. Dryophthoroides telnovi Legalov, sp. nov. from New Guinea (Star Mountains) is similar to D. seftoni (Zimmermann, 1944) bit differs in the shorter and thicker rostrum and narrower pronotum. It is distinguish from D. beccarii (Pascoe, 1885) in the smaller body size, thicker rostrum, coarser punctured pronotum, not subparallel elytra and narrower elytral interstriae. Dryophthoroides insularis Legalov, sp. nov. from North Moluccas (Bacan Islands) differs from D. telnovi Legalov, sp. nov. in the wider, laterally weakly rounded pronotum with a more finely punctured pronotal disc, the stronger widened interstria five at apex, the smaller punctures in elytral striae, the wider elytral interstriae and the longer and thinner rostrum. Nephius continentalis Legalov, sp. nov. from Laos (Hua Phan Prov.) differs from N. kalimantanensis Legalov, 2022 in the thicker and shorter rostrum, the pronotum lacking the sharp preapical constriction, the elytra with the greatest width postmedium, the medially not depressed lateral sides of the pronotum, and the obsolete humeri. Nephius philippinensis Legalov, sp. nov. from the Philippines (Mindanao Is., Bukidnon Prov.) differs from N. mindanaoensis Legalov, 2020 in the sparsely punctate pronotum with a median longitudinal groove and lacking four premedian pilose ridges, the elytral interstriae with weak pilose ridges, and the less curved rostrum.

Abstract
Four new species of the genera Dryophthoroides Roelofs, 1879 and Nephius Pascoe, 1885 from the tribe
Stromboscerini of the subfamily Dryophthorinae are described and illustrated. Dryophthoroides telnovi Legalov, sp.
nov. from New Guinea (Star Mountains) is similar to D. seftoni (Zimmermann, 1944) bit differs in the shorter and
thicker rostrum and narrower pronotum. It is distinguish from D. beccarii (Pascoe, 1885) in the smaller body size,
thicker rostrum, coarser punctured pronotum, not subparallel elytra and narrower elytral interstriae. Dryophthoroides
insularis Legalov, sp. nov. from North Moluccas (Bacan Islands) differs from D. telnovi Legalov, sp. nov. in the wider,
laterally weakly rounded pronotum with a more finely punctured pronotal disc, the stronger widened interstria five at
apex, the smaller punctures in elytral striae, the wider elytral interstriae and the longer and thinner rostrum. Nephius
continentalis Legalov, sp. nov. from Laos (Hua Phan Prov.) differs from N. kalimantanensis Legalov, 2022 in the
thicker and shorter rostrum, the pronotum lacking the sharp preapical constriction, the elytra with the greatest width
postmedium, the medially not depressed lateral sides of the pronotum, and the obsolete humeri. Nephius philippinensis
Legalov, sp. nov. from the Philippines (Mindanao Is., Bukidnon Prov.) differs from N. mindanaoensis Legalov, 2020 in
the sparsely punctate pronotum with a median longitudinal groove and lacking four premedian pilose ridges, the elytral
interstriae with weak pilose ridges, and the less curved rostrum.
Key words: Biodiversity, Curculionoidea, Dryophthorinae, Stromboscerini, Laos, Philippines, Indonesia.
Introduction
The tribe Stromboscerini belongs to subfamily Dryophthorinae of the family Curculionidae. The tribe
includes thirteen extant and two fossil genera (Grebennikov 2018; Legalov 2016; Legalov et al. 2019;
Nazarenko and Perkovsky 2009). Almost all modern species are distributed in the Oriental Region, and only
the genus Stromboscerus Schoenherr, 1838 in Madagascar and an undescribed form are listed for Uganda

(Grebennikov 2018). This work continues the study of the tribe Stromboscerini by Legalov (2019, 2020b,
2021a, 2021b, 2021c, 2021d, 2022a, 2022b).
In this paper, the new species of the genera Dryophthoroides Roelofs, 1879 and Nephius Pascoe,
1885 from Laos, the Philippines and Indonesia are described.
Material and methods
Type specimens are kept in the ISEA = Institute of Systematics and Ecology of Animals (Russia:
Novosibirsk) and NME = Naturkundemuseum (Germany: Erfurt).
Descriptions, body measurements, and photographs, were prepared using the Zeiss Stemi 2000-C
dissecting stereomicroscope.
The terminology of the weevil body is according to Lawrence et al. (2010).
The systematics of studied taxa are based on the works of Grebennikov (2018) and Legalov (2020a).

Taxonomic entities included in the present key are: new tribe Sipalomimini Legalov, trib. n. (type genus Sipalomimus Voss, 1958), subtribe Echinocnemina Legalov, subtrib. n. (type genus Echinocnemus Schoenherr, 1843) of the tribe Erirhinini, subtribes Crepidotina Legalov, subtrib. n. (type genus Crepidotus Schoenherr, 1838) and Laogenina Legalov, subtrib. n. (type genus Laogenia Pascoe, 1874) of the tribe Litosomini, Geochina Legalov, subtrib. n. (type genus Geochus Broun, 1882) of the tribe Phrynixini Kuschel, 1964, Alaocybites dubatolovi Legalov, sp. n. from Khabarovskii Krai are described. The systematic positions of Storeini Lacordaire, 1863, placem. n. and Dorytomini Bedel, 1886, placem. n. are changed. Changes of status for Sitophila Csiki, 1936, stat. n., Diocalandrina Zimmerman, 1993, stat. n., Stenoscelidina Wollaston, 1877, stat. n., Choerorhinina Folwaczny, 1973, stat. n. and Sphenocorynina Lacordaire, 1865, stat. n. are made. Statuses of Dorytomini Bedel, 1886, stat. res., Rhyncolina Gistel, 1856, stat. res., Onycholipini Wollaston, 1873, stat. res. and Himatinini Konishi, 1962, stat. res. are recovered. New synonyms, Aphyllurini Voss, 1955, syn. n. to Pseudomimina Voss, 1939 and Proecini Voss, 1956, syn. n. to Cossonini Schoenherr, 1825 are established. A keys to the tribes and subtribes of Erirhininae, Dryophthorinae and Cossoninae are provided. Systematic lists of tribes and subtribes of Entiminae are given.

All 13 Recent genera currently assigned to the tribe Stromboscerini are studied and illustrated based mainly on the type specimens of the type species. Nominal monotypic genus Parasynommatus Voss, 1956 from New Guinea is herein transferred to Cossoninae incertae sedis. The genus Nephius is notably dissimilar to the rest of the tribe and perhaps renders it paraphyletic. Besides the monotypic type genus endemic to Madagascar, the tribe is distributed in a triangle delimited by Japan, Sri Lanka and northern Australia; two new tribe records from continental Africa (Uganda) and the Western Hemisphere (Cuba) are reported and illustrated. Assignment of both fossil monotypic genera to the tribe was done outside of the cladistic framework and remains questionable. Judging by external similarity, the likeliest closest relative of Stromboscerini (with or without Nephius and, perhaps, Stromboscerus) is the tribe Dryophthorini with three Recent genera.
