Seniczak Stanislaw; Ivan Otilia; Seniczak Anna | Zootaxa, 2024 | |
RezumatThe morphological ontogeny of Oribatula pannonica Willmann, 1949 is described and illustrated. Most prodorsal setae of juveniles are of medium size, and bothridial seta is clavate. The larva has 11 pairs of gastronotal setae, including h2, most are of medium size and barbed, nymphs have 13 pairs (p3 absent), of which most are short and smooth. Basal excentrosclerites are present at nine pairs of gastronotal setae (c1, c2, d-, l-series, h1) in the larva, and at 12 pairs (c1, c2, d-, l-, h-series, p1) in the nymphs. The morphology of adult O. pannonica is compared with congeners with 13 pairs or an unknown number of notogastral setae. |

Seniczak Stanislaw; Ivan Otilia; Kaczmarek Slawomir; Seniczak Anna | Systematic And Applied Acarology, 2023 | |
RezumatThe morphological ontogeny of Amerobelba decedens Berlese, 1908 is described and illustrated. In the adult of this species, the bothridial seta is setiform, unilaterally ciliate, notogastral setae are short and barbed, and sexual dimorphism is present on tarsus IV. Most prodorsal setae of juveniles are short and smooth, except for mediumsized ro, barbed in the nymphs. The bothridial seta is long, setiform and barbed in distal part. The gastronotal setae are of medium size and barbed, except for smooth c1 and c2 in all juveniles, and smooth of d-series and short h2 in the larva. Setae c1 and c2 are inserted on large macrosclerite, and other gastronotal setae are inserted on individual microsclerites, except for h2 in the larva. The anal and anogenital regions are reticulate, and adanal setae are inserted on individual microsclerites. The nymphs are quadrideficient and eupheredermous, i.e. they lose setae of d-series and carry the exuvial scalps of previous instars. In this species, seta d accompanies solenidion & sigma; on genu III and & phi; on tibia III and IV, both in the juveniles and adults. It is a xero-thermophilous species, with one generation per year. |

Seniczak Stanislaw; Ivan Otilia; Kolesnikov Vasiliy B.; Kaczmarek Slawomir; Marquardt Tomasz; Seniczak Anna | Systematic And Applied Acarology, 2023 | |
RezumatThe morphological ontogeny of Eubelba danubedeltaica sp. nov. is described and illustrated. The adult of E. danubedeltaica is most similar to E. sculpta (Mihelcic, 1957) which differs from E. danubedeltaica by the presence of tubercle E2p, slightly longer seta c1 and leg IV, and thicker and clearly barbed epimeral, genital, aggenital and anal setae whereas in E. danubedeltaica tubercle E2p is absent and these setae are thinner and most are smooth, except for finely barbed genital and anal setae that are clearly visible at a high SEM magnification. In the juveniles of E. danubedeltaica, most prodorsal setae are of medium size, except for short seta in in the nymphs and very long setiform bothridial seta which are strongly curved in the distal part. Most gastronotal setae of juveniles are long, or very long, except for medium-sized c3, la, lm and h2, and short h3 in the larva, and medium-sized c3 and p2 in nymphs. The nymphs are quadrideficient and eupheredermous, i.e. they have lost the d-series setae and carry the exuvial scalps of previous instars using a cornicle located between setal pair h3. In all juveniles, the famulus e on tarsus I is sunken but is emergent in the adult. Seta d accompanies solenidion & sigma; on genua I-III and & phi; on tibiae II-IV. |

Morphological Ontogeny Of Ctenobelba Pilosella (Acari: Oribatida: Ctenobelbidae), With Comments On Ctenobelba Balogh |
Seniczak Stanislaw; Ivan Otilia; Kaczmarek Slawomir; Seniczak Anna | Systematic And Applied Acarology, 2021 | |
RezumatThe morphological ontogeny of Ctenobelba pilosella Jeleva, 1962 is described and illustrated. This species was investigated from its description mainly in ecological aspect. It was recorded from the forest and meadow soils, with rather low density, and small percent of juveniles.The adult is of medium size and has setiform bothridial seta, with 6-10 anterior spines. Notogaster is covered with asteriform granules and has 10 pairs of medium size, barbed setae. Seta d is absent from genua I-III and all tibia. Bothridial seta of juveniles is setiform and barbed, prodorsal and gastronotal setae are short, except of medium size ro and long, curved inwards lp. Nymphs are quadrideficient and eupheredermous i.e. they carry the exuvial scalps of previous instars. Anal valves of protonymph and deutonymph have two pairs of alveolar setae, which is rare in Brachypylina. The juveniles have seta d on all genua and tibiae. |

Morphological Ontogeny Of Oribatella Reticulata (Acari: Oribatida: Oribatellidae) |
Seniczak Stanislaw; Ivan Otilia; Marquardt Tomasz; Seniczak Anna | International Journal Of Acarology, 2021 | |
RezumatThe morphological ontogeny of Oribatella reticulata Berlese, 1916 is described and illustrated. The nymphs of this species are apopheredermous, i.e. they carry the exuvial scalps of previous instars away from the dorsal integument, using modified setal pair da. The larva has 12 pairs of gastronotal setae, including short h(3), the nymphs have 15 pairs, and most are long and barbed. In all juveniles, a humeral organ is absent, which is unique in Oribatella. The tritonymph of this species has more thickened setae on leg segments (d on all femora and genu IV, ev' on femora III and IV, l on femora I-III and genua and tibiae I-IV) than the adult (l on genua and tibiae I and II, l' on genu and tibia IV). |

Morphological Ontogeny Of Perlohmannia Nasuta (Acari, Oribatida, Perlohmanniidae), With Comments On Perlohmannia Berlese |
Seniczak Stanislaw; Ivan Otilia; Marquardt Tomasz; Seniczak Anna | Zootaxa, 2021 | |
RezumatThe morphological ontogeny of Perlohmannia nasuta Schuster, 1958 is described and illustrated. The adult of this species is the most similar to that of P. dissimilis (Hewitt, 1908), but differs from it by having alveolar seta exp (versus setiform in P. dissimilis), which is unique in Perlohmannia Berlese, 1916. It also has more spines on the bothridial seta and shorter seta c(1) than has P. dissimilis. The juveniles of P. nasuta have the prodorsal seta exp alveolar, 7-8 anterior spines on the bothridial seta, and seta e(2) longer than f(2). Claparede's organ of larva is long and cudgel-shaped. This species differs clearly from P. dissimilis in the ontogeny of leg setae. In both species, hypertrichy occurs on tarsi, especially on tarsus I, but P. nasuta has more setae on tarsus I of deutonymph, tritonymph and adult than has P. dissimilis. |
