Contribution to knowledge of the oribatid mite genus Achipterina (Acari, Oribatida, Ceratokalummidae)

Sergey G. Ermilov Jenő Kontschán V. M. Salavatulin Vladimir A. Khaustov

Publication Name: International Journal of Acarology

Publication Date: 2025-05-19

Volume: 51

Issue: 4

Page Range: 251-257

Description:

Achipterina (Oribatida, Ceratokalummidae) currently comprises four species, collectively distributed in the tropical and subtropical areas. We describe a new species—A. mangrovicasp. nov.—based on adults collected from litter of a mangrove forest in the Can Gio Biosphere Reserve, southern Vietnam. It is the first representative of the family discovered in the Vietnamese fauna. The new species is characterized in having a bidentate rostrum, setiform rostral and lamellar setae, long inner tooth of lamellar cusp, unilaterally fusiform bothridial seta, long interlamellar seta, dentate anterior part of pteromorph, oval and oblique notogastral porose area Aa. The morphology of the gnathosoma, ovipositor, and legs are presented for the first time for Achipterina. An identification key and summary of distribution and habitats of the known species of Achipterina are provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:906EA4DE-A0A3-475C-B273-F8327F44832F.

A new remarkable representative of Uropodina mites from Seychelles (Acari, Mesostigmata, Trematuridae)

Sergey G. Ermilov Jenő Kontschán

Publication Name: Zookeys

Publication Date: 2025-01-01

Volume: 1229

Issue: Unknown

Page Range: 289-296

Description:

A new genus, Trematirunella gen. nov. (Mesostigmata: Uropodina: Trematuridae), with Trematirunella seychellia sp. nov. as its type species, is described, based on a female, males, and deutonymphs collected in soil samples from the Seychelle Islands. The new genus belongs to the family Trematuridae based on the shape of the corniculi, gnathosomal setae, tritosternum and chelicerae. Members of the new genus bear a preanal suture on the ventral shield, two pairs or more pairs of wide, robust and sword-like setae on the caudal part of the dorsal shield, very dense setation on the caudal area of the marginal shield and an incision on the anterior part of the dorsal shield. These characters are missing in the other genera of Trematuridae. Two previously described species (Trichouropoda lagunae Hirmatsu & Hirschmann, 1988 and Trichouropoda palawanensis Hirschmann & Hirmatsu, 1990) from the Philippines are transferred to the new genus, as Trematirunella lagunae (Hirmatsu & Hirschmann, 1988), comb. nov. and Trematirunella palawanensis (Hirschmann & Hirmatsu, 1990), comb. nov. The new species differs from its congeners in the sculptural pattern of the female genital shield and in the shape of the robust and sword-like setae on the caudal area of the dorsal shield.

Issue: Unknown

Page Range: 39-50

Description:

The genus Elegansovella Hirschmann, 1989 (Mesostigmata: Uropodina: Urodinychidae) is resurrected for species of the Uroobovella elegans-group. This genus differs from the other taxa of Uroobovella Berlese, 1903 sensu lato based on the shape of the idiosoma and the caudal and dorsal setae. Three species from the Uroobovella elegans-group are transferred to the genus Elegansovella, as E. pectintata (Hirschmann, 1973), comb. nov., E. pectinatasimilis (Hiramatsu, 1980), comb. nov. and E. serangensis (Hiramatsu, 1980), comb. nov. The other seven species from this species group are transferred to Monstrobovella gen. nov., as M. crustosa (Vitzthum, 1926), comb. nov., M. enodis (Hiramatsu, 1985), comb. nov., M. faceta (Hiramatsu & Hirschmann, 1978), comb. nov., M. facetaoides (Hiramatsu & Hirschmann, 1978), comb. nov., M. imadatei (Hiramatsu, 1980), comb. nov., M. incerta (Hiramatsu & Hirschmann, 1978), comb. nov. and M. incertaoides (Hiramatsu & Hirschmann, 1978), comb. nov. The new genus differs from Elegansovella by the shape of the idiosoma and the shape of marginal and dorsal setae. Six Monstrobovella species occur in the Oriental Realm and only one species is known from the Neotropical region. The present paper contains the description of a second Neotropical species of Monstrobovella (M. mancocapaci sp. nov.) which was found in Peru. The new species differs from its Neotropical congener in the dorsal and marginal setation.

Description:

Phymatodiscidae fam. nov. is diagnosed, with Phymatodiscus as the type genus. A new genus, Bardizon gen. nov., with Bardizon eotvosi sp. nov. (from Indonesia) as the type species, is erected to accommodate the Phymatodiscus species with an eye-like dorsal depression. Six Phymatodiscus species are reclassified as Bardizon: B. aokii (Hiramatsu, 1985), comb. nov., B. haradai (Hiramatsu, 1985), comb. nov., B. oculatus (Hirschmann, 1977), comb. nov., B. kuni (Kontschán & Starý, 2011), comb. nov., B. insolitus (Kontschán & Ripka, 2016), comb. nov., and B. malayicus (Kontschán & Starý, 2012), comb. nov. The new species differs from the previously described congeners in the sculptural pattern, the shapes of the dorsal and ventral setae, and the sculptural pattern of the sternal shield of the male and the genital shield of the female. A list of all known phymatodiscid species is presented. Phymatodiscus titanicus (Berlese, 1905) is moved to the genus Bostocktrachys: B. titanicus (Berlese, 1905), comb. nov. (family Trachyuropodidae).

Publication Name: Acarologia

Publication Date: 2023-01-01

Volume: 63

Issue: 3

Page Range: 770-782

Description:

The present study is based on oribatid mite materials collected from leaf litter in two forest locations in Cuba. A list of 64 species, belonging to 47 genera and 31 families, is presented. Of these, one genus and two species are recorded for the first time from the Neotropical region; 17 species, one subgenus, six genera, and two families are recorded for the first time from Cuba. Two new species of the superfamily Oripodoidea—Lagenobates fossatus Ermilov and Kontschán n. sp. (Haplozetidae) and Muliercula curvilineata Ermilov and Kontschán n. sp. (Scheloribatidae)—are described.

New Angulobaloghia species and records (Acari: Mesostigmata: Rotundabaloghiidae) from the Oriental region

Sergey G. Ermilov Jenő Kontschán

Publication Name: Acarologia

Publication Date: 2023-01-01

Volume: 63

Issue: 1

Page Range: 253-261

Description:

Two new Angulobaloghia species are described from Southeast Asia: A. nabau sp. nov. from Malaysia and A. badangi sp. nov. from Singapore. Angulobaloghia nabau sp. nov. has a three-peaked female genital shield, which is unique within the genus Angulobaloghia. Angulobaloghia badangi sp. nov. is distinctive by having the female genital shield between the central area of coxae II, its rectangular apical margin, and the sternal shield with oval pits. New localities for two known Angulobaloghia species, A. scrobia Kontschán and Stary, 2011 and A. vietnamensis (Kontschán, 2008), are presented from Vietnam.

Sergey G. Ermilov Jenő Kontschán

Publication Name: Acta Zoologica Academiae Scientiarum Hungaricae

Publication Date: 2023-01-01

Volume: 69

Issue: 2

Page Range: 127-138

Description:

The genus Micherdzinskiiobovella Hirschmann, 1989 (Mesostigmata: Uropodina: Uropodinychidae) is resurrected for species of the Uroobovella micherdzinskii-group. This genus differs from the other taxa of the Uroobovella sensu lato based on the shape of body, the first gnathosomal setae, the peritreme and the number of the ventral setae. All species from the Uroobovella micherdzinskii-group are moved to the genus Micherdzinskiiobovella, as M. japonica (Hiramatsu et Hirschmann, 1977) comb. n., M. levigata (Hirschmann et Hiramatsu, 1990) comb. n., M. makilingensis (Hirschmann et Hiramatsu, 1990) comb. n., M. mitakensis (Hiramatsu et Hirschmann, 1977) comb. n., M. pauxilla (Hiramatsu, 1981) comb. n., M. pauxillaoides (Hirschmann, 1981) comb. n., M. similimitakensis (Hirschmann, 1981) comb. n., M. topali (Hirschmann, 1981) comb. n., and M. multisetosa (Kontschán et Starý, 2011) comb. n. A new species (M. petofii sp. n.) is described, based on one female and four males collected from Singapore. The new species differs from the congeners in the length and shape of the ventral setae.

Publication Name: Acta Zoologica Academiae Scientiarum Hungaricae

Publication Date: 2023-01-01

Volume: 69

Issue: 4

Page Range: 313-321

Description:

A new oribatid mite subgenus of the genus Amboroppia (Oribatida, Oppiidae) –A. (Quintanoppia) subgen. n., with A. (Quintanoppia) defectofossulata sp. n. as type species – is described, based on material collected from Mexico. It can be distinguished from the nominate subgenus by the absence concavities between rostrum and transcostula and behind transcostula, and the presence of strong teeth on lateral sides of prodorsum. A revised generic diagnosis, identification key and data on distribution and habitats of representatives of Amboroppia are presented.
