New Oripodoidea (Acari, Oribatida) from Myanmar SERGEY G. ERMILOV Tyumen State University, Tyumen, Russia. E-mail: [email protected]

Abstract The oribatid mite taxa (Acari, Oribatida), superfamily Oripodoidea, families Scheloribatidae and Caloppiidae, genera Scheloribates Berlese, 1908 and Zetorchella Berlese, 1916, and the species Zetorchella orbiculata (Wen & Zhao, 1994), are recorded in Myanmar for the first time. Two new oripodoid species are described: Scheloribates natmaensis sp. nov. (Scheloribatidae) is most similar to S. yamaeensis Nakamura, Hashimoto, Nishi, Nakamura & Fujikawa, 2015, but differs by the larger body size, narrowly triangular rostrum, clavate, rounded distally bothridial setae and longitudinal stria on the notogaster; Zetorchella taungensis sp. nov. (Caloppiidae) is most similar to Z. nortoni Ermilov, Sidorchuk & Rybalov, 2010, but differs by the larger body size, longer notogastral setae, bothridial setae shorter than humeral notogastral setae c and notogastral setae c and p1 similar in length. Key words: mites, record, new species, systematics, morphology, Scheloribates, Zetorchella

Introduction This work is part of my study (Ermilov 2017) of the Myanmar oribatid mites (Acari, Oribatida) received from the collection of the Senckenberg Museum of Natural History (Görlitz, Germany) and includes data on the superfamily Oripodoidea. During taxonomic identification, I found three species of oripodoids; of these, two species are new to science, one belonging to the genus Scheloribates Berlese, 1908 (Scheloribatidae), from the nominative subgenus, and the other to the genus Zetorchella Berlese, 1916 (Caloppiidae), and one species, Zetorchella orbiculata (Wen & Zhao, 1994), which has been described from southern China. The main goal of the paper is to describe and illustrate the two new species. The superfamily Oripodoidea and listed families, genera and species are recorded for the first time in Myanmar. The genus Scheloribates comprises several subgenera (based on different opinions; e.g. Subías 2004, updated 2016; 2017; Ermilov & Anichkin 2014) and about 250 species and 20 subspecies, which have a cosmopolitan distribution collectively. The genus Zetorchella comprises 22 species, which are distributed in the Ethiopian, Neotropical, Oriental and southern Palaearctic regions (Subías 2004, updated 2017).

Material, methods, terminology and abbreviations The collection locality and habitat for each studied oripodoid species are given in the respective "Material examined" section. Specimens were mounted in lactic acid on temporary cavity slides for measurement and illustration. The body length was measured in lateral view, from the tip of the rostrum to the posterior edge of the ventral plate. Notogastral width refers to the maximum width of the notogaster (behind 1022

Formulas for leg setation are given in parentheses according to the sequence trochanter–femur–genu–tibia–tarsus (famulus included). Formulas for leg solenidia are given in square brackets according to the sequence genu–tibia–tarsus.

Remarks Scheloribates natmaensis sp. nov. can be ascribed to the striolatus-group (Ermilov & Starý 2017). Representatives of this group have an entire or partially striate notogaster. The new species is morphologically most similar to S. yamaeensis Nakamura, Hashimoto, Nishi, Nakamura & Fujikawa, 2015 from Japan in having a striate notogaster in the posterior part only, but differs by the larger body size (879–962 × 597–664 vs. 457–564 × 293–400), narrowly triangular rostrum (vs. broadly rounded), clavate, rounded distally bothridial setae (vs. fusiform, pointed distally) and longitudinal stria on notogaster (vs. stria oriented transversely).
