Three new species of oribatid mites of the superfamily oripodoidea (acari, oribatida) from Vietnam

Texto integral

The arboreal fauna of oribatid mites (Acari, Oribatida) in Vietnam is insufficiently studied (Corpuz-Raros, Ermilov, 2020; Salavatulin et al., 2022). The main goal of our paper is to describe three new species of the superfamily Oripodoidea belonging to the genera Phauloppia Berlese 1908 (family Oribatulidae), Oripoda Banks 1904 and Pirnodus Grandjean 1956 (family Oripodidae), based on materials collected from trees in the Cat Tien National Park, southern Vietnam.

Phauloppia and Oripoda comprise 25 and 38 species (Subías, 2022; Ermilov, Salavatulin, 2023), respectively, which have a cosmopolitan distribution except the Antarctic region (Subías, 2022). Pirnodus comprises six species (Ermilov, Salavatulin, 2023) which are distributed in the Afrotropical, Australasian, Neotropical, and southern Palaearctic regions (Subías, 2022; Ermilov, Salavatulin, 2023). Presently, two species of Phauloppia – P. adjecta Aoki et Ohkubo 1974, P. dilatata Ermilov et Salavatulin 2023; four species of Oripoda – O. canagaratnami (Balogh 1970), O. excavata Mahunka 1988, O. luminosa (Hammer 1979), O. pinicola Aoki et Ohkubo 1974; and one species of Pirnodus – P. partiarus Ermilov et Salavatulin 2023 are registered in Vietnam (Corpuz-Raros, Ermilov, 2020; Salavatulin et al., 2022; Ermilov, Salavatulin, 2023).

MATERIAL AND METHODS

Specimens. Samples of bark and branches were collected via climbing trees (using spikes and other special equipment). Mites were subsequently extracted by high-pressure flushing and further heptane flotation in laboratory conditions. Detailed descriptions of arboreal acarofauna collection and extraction techniques are presented in Salavatulin (2019).

Observation and documentation. For measurement and illustration, specimens were mounted in lactic acid on temporary cavity slides. All measurements are in micrometers (μm). Body length was measured in lateral view, from the tip of the rostrum to the posterior edge of the notogaster; other structures were oriented to avoid parallax errors. Notogastral width refers to the maximum width in dorsal aspect. Setal lengths were measured perpendicular to their long axes, accounting for curvature. Formulas for leg solenidia are given in square brackets according to the sequence genu-tibia-tarsus. Drawings were made with a camera lucida using a Leica DM 2500 light microscope.

Terminology and conventions. Morphological terminology used herein mostly stems from the following papers on Oribatulidae and Oripodidae: Grandjean (1950, 1956); Ermilov, Salavatulin (2023). Leg setal nomenclature follows Norton (1977); for overview see Norton and Behan-Pelletier (2009).

Comparison.

However, the new species differs from P. detectidens in the presence (versus absence) of short translamellar lines near lamellae and in the absence (versus presence) of sexual dimorphism (e. g., males of P. detectidens are characterized by the absence of the anterior margin of notogaster medially and by the bothridial seta completely covered by the anterior margin of the notogaster; females of P. detectidens are characterized by a rounded rostrum and by the genital aperture distinctly larger than anal aperture).

Etymology. The specific epithet concavus is Latin for “concavity” and alludes to the concave rostrum in the new species.
