Two new species of oribatid mites of Lasiobelba (Acari, Oribatida, Oppiidae) from Nepal, including a key to all species of the genus

Abstract Two new species of oribatid mites of the genus Lasiobelba (Oribatida, Oppiidae), Lasiobelba (Lasiobelba) daamsae sp. n. and Lasiobelba (Antennoppia) nepalica sp. n., are described from eastern Nepal. Lasiobelba (L.) daamsae sp. n. is most similar to L. (L.) remota Aoki, 1959 and L. (L.) gibbosa (Mahunka, 1985), however, it differs from both by the anterior part of pedotecta I specifically curved, rostrum pointed and exobothridial setae not shorter than bothridial setae. Lasiobelba (Antennoppia) nepalica sp. n. is most similar to L. (A.) granulata (Mahunka, 1986), however, it differs from the latter by the larger body size, exobothridial setae longer than rostral setae and bothridial setae not longer than interlamellar setae. An identification key to known species of Lasiobelba is given.

In the course of taxonomic identification of oribatid mites from Nepal 1 (Ermilov et al. 2013, we found two new species of the genus Lasiobelba; one belonging to Lasiobelba (Lasiobelba), other to Lasiobelba (Antennoppia). The first goal of our paper is to describe these species. The second goal of our paper is to present an identification key to all known species of Lasiobelba.
Holotypes and paratypes 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. The notogastral width refers to the maximum width in dorsal aspect. Lengths of body setae were measured in lateral aspect. All body measurements are presented in micrometers. Formula for leg setation is given in parentheses according to the sequence trochanter-femur-genutibia-tarsus (famulus included). Formula for leg solenidia is given in square brackets according to the sequence genu-tibia-tarsus. General terminology used in this paper follows that of Norton and Behan-Pelletier (2009). 1 Results of the Himalaya Expeditions (1980,1983) of Dr. Jochen Martens.
Type deposition. The holotype and one paratype are deposited in the collection of the Senckenberg Institution Frankfurt, Germany; three paratypes are deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia.
Etymology. The specific name is dedicated to Mrs. Beate Daams for her assistance in Nepalese scientific researches.
Legs. Generally, similar to Lasiobelba (Lasiobelba) daamsae sp. n. (see also Table 1). Type deposition. The holotype and one paratype are deposited in the collection of the Senckenberg Institution Frankfurt, Germany; two paratypes are deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia.
