Digamasellid mites (Acari: Mesostigmata) in association with saproxylic darkling beetles (Coleoptera: Tenebrionidae) and wood-decaying fungi (Polyporales) in Slovakia

PETER MAŠÁN — Thu, 24 Apr 2025 00:00:00 +1200

Three species of digamasellid mites adapted to life in wood-decaying polypore fungi and phoretically associated with saproxylic and fungivorous beetles of the family Tenebrionidae are described from adult and deutonymphal stages from forest habitats in Slovakia. Two of the mites are described as new species: Bulbolaelaps neomidae sp. nov., the second member of the genus, whose developmental stages were previously unknown, is specifically associated with the tinder fungus Fomes fomentarius (L.) Fr., and its deutonymphs are phoretically dispersed by the beetle Neomida haemorrhoidalis (Fabricius); Insectolaelaps diaperi sp. nov. inhabits various non-perennial polypores infested by the beetle Diaperis boleti (Linnaeus), whose adults serve as a specific host for the phoretic deutonymphs. The third species described, Insectolaelaps latopini (Hirschmann & Wiśniewski, 1982), lives in various perennial polypores, mainly in Fomes fomentarius, which it colonises by phoresy on the black tinder beetle Bolitophagus reticulatus (Linnaeus), but also occasionally on other host species such as Bolitophagus interruptus Illiger and Eledonoprius armatus (Panzer). Each mite exhibits at least one unique morphological feature that is rare or absent in the Digamasellidae: the females of B. neomidae have only three pairs of setae on the sternal shield, the deutonymphs of I. diaperi have only two pairs of setae on the sternal shield, and I. latopini possesses only one anterolateral seta on the genu and tibia of legs III.

**Review of the genus Streblocera Westwood, 1883 (Hymenoptera, Braconidae, Euphorinae) in Vietnam, with descriptions of nine new species**

PHAM QUYNH MAI, KHUAT DANG LONG, NGUYEN DUC HIEP, DANG THI HOA, TRAN DINH DUONG — Thu, 24 Apr 2025 00:00:00 +1200

The genus Streblocera Westwood with four subgenera Asiastreblocera Belokobylskij, Eutanycerus Förster, Streblocera Westwood and Villocera Chen & van Achterberg, from Vietnam, is revised with nine new species described and fully illustrated, viz. Streblocera (Asiastreblocera) laichauensis Long, sp. nov.; S. (Eutanycerus) hatinhensis Long, sp. nov.; S. (E.) neutra Long, sp. nov.; S. (E.) netrangana Long, sp. nov.; S. (E.) parucifera Long, sp. nov.; S. (Streblocera) duplicata Long, sp. nov.; S. (S.) huuliena Long & PQMai, sp. nov.; S. (S.) necurvata Long, sp. nov.; and S. (S.) setosa Long, sp. nov. Two subgenera, Streblocera and Villocera are recorded for the first time in Vietnam, with S. (Eutanycerus) cornis Chen & He, 2000 and S. (Villocera) villosa Papp, 1985 newly recorded. The comparative morphological characters of Streblocera species are discussed and an illustrated key to four subgenera and Streblocera species of Vietnam. Their in-country distribution are also mapped.

**The epigean pseudoscorpions of the genus Neobisium from Corsica and Sardinia, with description of a new species (Pseudoscorpiones: Neobisiidae)**

GIULIO GARDINI, PIETRO GARDINI — Thu, 24 Apr 2025 00:00:00 +1200

A taxonomic revision of the epigean species of Neobisium (Neobisium) Chamberlin, 1930 from Corsica and Sardinia is proposed and a key is provided that also includes the subterranean species from the same geographical area. The new species Neobisium (Neobisium) knoflachae n. sp. (♂♀, loc. typ.: Corsica, Calvi, Forêt de Bonifatu, Bocca di Erbaghiolu) is described. Neobisium (Neobisium) gennargentui Callaini, 1983 (n. stat.) and Neobisium (Neobisium) major Callaini, 1982 (n. stat.) are elevated from subspecies of Neobisium (Neobisium) bernardi Vachon, 1937 and Neobisium (Neobisium) mahnerti Heurtault, 1980, respectively.

New records of the squat lobster genus Uroptychus (Crustacea: Decapoda: Anomura: Chirostylidae) from West Africa: unexpected occurrence of the western Atlantic species U. nitidus (A. Milne Edwards, 1880) and description of a new species

KEIJI BABA, ENRIQUE MACPHERSON, PAULA C. RODRÍGUEZ-FLORES — Thu, 24 Apr 2025 00:00:00 +1200

Collections of a recent expedition to Guinea-Bissau, West Africa conducted by the Spanish Institute of Oceanography contain five specimens of two unusual species of the squat lobster genus Uroptychus Henderson, 1888, taken at 909 m depth. One of these represents an unidentified species herein described as U. pauroptilus sp. nov. and the other four are referable to U. nitidus (A. Milne Edwards, 1880), so far known only from the western Atlantic. The morphological relationships between the new species and its close relatives U. maroccanus Türkay, 1976 and U. tuerkayi Baba & Macpherson, 2017, both from the eastern Atlantic, are discussed. The identity of U. nitidus was confirmed by morphological and molecular analyses of a large series of specimens from the western and eastern Atlantic and by comparison with material of U. concolor (A. Milne-Edwards & Bouvier, 1894) from the eastern Atlantic. Phylogenetic relationships of these species as well as additional comparable species are discussed.

Chalinula tamoiensis sp. nov. (Porifera: Haplosclerida Chalinidae), a new species from Ilha Grande Bay, Rio de Janeiro state

TAYNÁ LUNA, ANDRÉ BISPO, EDUARDO LEAL ESTEVES — Thu, 24 Apr 2025 00:00:00 +1200

In the present study, we describe a new species belonging to the genus Chalinula from Ilha Grande Bay, Rio de Janeiro state, off Southeast Brazil. Chalinula tamoiensis sp. nov. is thinly to thickly encrusting, purple or pink coloured in life, with oscules raised in volcano shaped projections or more commonly flush with the surface, in thinly encrusting specimens. Skeleton typically anisotropic, with variable amounts of spongin and oxeas ranging from 59 to 90 µm long. Maximum likelihood analyses of large ribosomal subunit DNA (28S rRNA) recovered Chalinula polyphyletic. Chalinula tamoiensis sp. nov. clustered with a subset of species from other ocean basins and was distantly related to Chalinula molitba, from the Tropical Western Atlantic and Chalinula nematifera, from the Central Western Pacific, with which it shares a series of traits. A summary of morphological characters of all species belonging to the genus and new sequences of the larger ribosomal subunit DNA are also provided.

New species and notes of Agraeciini (Orthoptera: Tettigoniidae: Conocephalinae) from Surigao del Sur, Mindanao

KIM C. GRUMO, ALFREDO III A. GONO, OLGA MACAS NUÑEZA, MING KAI TAN — Thu, 24 Apr 2025 00:00:00 +1200

From San Miguel of the Mount Diwata Range, a new species of Anthracites was discovered and is described here: Anthracites inopinatus sp. nov. This new species is most similar to Anthracites furvuseques Tan, Baroga-Barbecho & Yap, 2018. From Lanuza, we report a new locality record for Salomona lumadae Tan, Baroga-Barbecho & Yap, 2018 in Surigao del Sur, having previously been described and known only from Siargao Island. A new species of Salomona was also found in Surigao del Sur and is described: Salomona manobo sp. nov. The calling song of this new species is also described here.

**Taxonomy of the genera Tropidopsilus Kieffer, 1908 and Masnerolyta Buhl, 1997 (Diapriidae: Belytinae) with description of a new species of Tropidopsilus from the Palaearctic region**

RYOJI KAWAI, VASILISA CHEMYREVA — Thu, 24 Apr 2025 00:00:00 +1200

The New World genus Tropidopsilus Kieffer, 1908 is recorded for the first time in the Palaearctic region. A new species of this genus, T. orientalis sp. nov., from Japan, is described and illustrated. The generic diagnosis of Tropidopsilus is revised and the genus name Masnerolyta Buhl, 1997 is recognized as a junior synonym of Tropidopsilus. The new combination, Tropidopsilus ruber (Buhl, 1997), comb. nov. is established.

**A new species of the genus Navicordulia Machado & Costa, 1995 from Ecuador (Insecta: Odonata: Corduliidae s.str.)**

GÜNTHER FLECK, WILLIAM A. HABER — Thu, 24 Apr 2025 00:00:00 +1200

Based on a single male specimen a new species of the genus Navicordulia Machado & Costa, 1995 from Ecuador is described and illustrated, representing the first described species for this country. The recent considerable westward expansion of the distribution of the genus is briefly discussed. The male of Navicordulia tangoyi sp. nov. can be separated from its congeners by the distinct shape and pilosity of the genital lobe and by the remarkable deflection of the distal fourth of the cerci. A differential diagnosis and an updated key to all known males of the genus are provided.
