Two new species of oribatid mites of the family Galumnidae (Acari, Oribatida) from Vietnam

Abstract

Two new species of oribatid mites of the family Galumnidae, Allogalumna monodactyla sp. n. and Galumna (Galumna) paracalcicola sp. n., are described from dark loamy soil under crown of Ficus sp. in southern Vietnam. Allogalumna monodactyla sp. n. is the first identified member of Allogalumna recorded for Vietnam. The identification keys to the species of Allogalumna from the Oriental region and species of Galumna (Galumna) from Vietnam and the calcicola-group are given.

Two new species of Pergalumna (Acari, Oribatida, Galumnidae) from Costa Rica, including a key to all species of the genus from the Neotropical region

“…Morphology of leg segments, setae and solenidia typical for Pergalumna (see Engelbrecht 1972; Ermilov et al 2010; Ermilov and Anichkin 2011). Formulae of leg setation and solenidia: I (1–4–3–4–20) [1–2–2], II (1–4–3–4–15) [1–1–2], III (1–2–1–3–15) [1–1–0], IV (1–2–2–3–12) [0–1–0]; homology of setae and solenidia indicated in Table 1.…”

“…Morphology of subcapitulum, palps and chelicerae typical for Pergalumna (see Engelbrecht 1972; Ermilov et al 2010; Ermilov and Anichkin 2011). Subcapitulum longer than wide (155–159 × 131–143).…”

The genus Scapheremaeus (Acari, Oribatida, Cymbaeremaeidae) in the oribatid mite fauna of New Zealand, with description of two new species

“…At present, the genus comprises more than 110 species and has a cosmopolitan distribution (except the Antarctic region) (Subías 2004, updated 2015; Ermilov and Anichkin 2015). The generic characters of Scapheremaeus are summarized by Colloff (2009).…”

“…The generic characters of Scapheremaeus are summarized by Colloff (2009). The identification keys to species from some regions and countries have been presented by Sitnikova (1975), Rios and Palacios-Vargas (1998), Balogh and Balogh (2002), Colloff (2010), Norton et al (2010), and Ermilov and Anichkin (2015). The information about juvenile instars is summarized by Norton and Ermilov (2014), with some new data added by Ermilov et al (2015).…”

New species and records of Galumna (Acari, Oribatida, Galumnidae) from Peru

“…Subgeneric diagnoses for G. (Galumna) and G. (Cosmogalumna) were presented by Ermilov et al (2013) and Ermilov and Corpuz-Raros (2015), respectively. Identification keys to selected species of Galumna (Galumna) were given by Shaldybina (1975), Balogh and Balogh (2002), Weigmann (2006), Bayartogtokh and Akrami (2014), Ermilov and Anichkin (2014b) and Ermilov et al (2015a, b); an identification key to all known species of Galumna (Cosmogalumna) was presented by Ermilov and Corpuz-Raros (2015). Methods -Specimens were mounted in lactic acid on temporary cavity slides for measurement and illustration.…”
