Morphological ontogeny of Melanozetes avachai n. sp., a unique member of Melanozetes (Acari: Oribatida: Ceratozetidae)

Morphological ontogeny of Melanozetes interruptus Zacher</p > (Acari, Oribatida, Ceratozetidae), and comments on Melanozetes Hull

“…In the adults of M. interruptus studied herein, the chelicera is chelate-dentate, seta cha is longer than chb, and both setae are barbed, as in M. avachai, M. paramollicomus, and M. stagnatilis (Seniczak et al 2016b, Seniczak & Seniczak 2018, Bayartogtokh et al 2021. In most of these species the palp setae are with short barbs, as in M. interruptus studied herein.…”

“…These species differ also from one another by the size of lamellar cusp and porose area A1, and the length of notogastral setae (Table 3). The femora are flattened, and femora I and II have a large ventral carina in most species, but in M. avachai femora are oval in cross-section, and a large ventral carina on femora I and II is absent (Seniczak et al 2016b).…”

“…The juveniles of M. interruptus are most similar to those of M. azoricus differing from it by seven morphological characters, whereas other species differ from M. interruptus by eight morphological characters (Table 4). From this comparison the most important is the shape of seta p 1 ; in the nymphs of M. interruptus this seta is inserted on basal microsclerite, which is unique in Melanozetes, in the nymphs of other species of Melanozetes seta p 1 is inserted on the gastronotal shield (Seniczak 1989a(Seniczak , 1993bSeniczak et al 2015Seniczak et al , 2016bSeniczak & Seniczak 2018;Bayartogtokh et al 2021). In the nymphs of all species solenidion ω 2 on tarsus I is inserted anterior to ω 1 , and is longer than ω 1 except for M. avachai and M. paramollicomus, in which this solenidion is as long as ω 1 (Seniczak et al 2016b, Bayartogtokh et al 2021.…”

“…The juveniles of Melanozetes species are relatively well known. Based on the catalogue of Norton and Ermilov (2014) and Seniczak et al (2015Seniczak et al ( , 2016b and Seniczak and Seniczak (2018), the morphological ontogeny of seven species of this genus is known. These species are: M. avachai Seniczak et al, 2016(see Seniczak et al 2016b, M. azoricus Weigmann, 1976 investigated by Seniczak et al (2015), M. interruptus Willmann, 1953, M. meridianus Sellnick, 1928 and M. mollicomus studied by Seniczak (1989aSeniczak ( , 1993b, M. paramollicomus Bayartogtokh et al, 2021, andM.…”

Study on the post-embryonic development of Striatoppia milii Sanyal and Basu, 2014 (Acari: Oribatida: Oppiidae) on the microfungus Trichoderma harzianum

“…Oppiidae is one of the largest families in the suborder Oribatida, comprising about 132 genera, 41 subgenera, and 1048 species; they are distributed worldwide (Subías 2014(Subías update 2021. The members included in the family Oppidae are mainly fungivores (Seniczak 1975). In India, the family Oppiidae comprises about 26 genera and, among these, the genus Striatoppia comprises eight species.…”
