This paper provides a comprehensive description of the morphological characteristics of the developmental stages (larva, protonymph, deutonymph, and adult) of Amblyseius herbicolus (Chant, 1959) and Amblyseius lentiginosus Denmark & Schicha, 1974. Both species used were sourced from laboratory-reared colonies fed with the dried fruit mite Carpoglyphus lactis (L.) (Acari: Carpoglyphidae).

The morphological ontogeny of Neoseiulus zwoelferi (Dosse, 1957) (Acari: Phytoseiidae) was studied based on specimens from a laboratory culture originally collected from the leaves of Xanthium sibiricum Patrin ex Widder (Asteraceae) in Taigu County, Shanxi province, China. All life stages including larva, protonymph, deutonymphal female and male, adult female and male were described and illustrated. The morphological characters of Neoseiulus species with both immature and adult stages are discussed. Neoseiulus subreticulatus (Wu, 1987) is considered a junior synonym of Neoseiulus zwoelferi (Dosse, 1957).

This paper reports the results of our studies of the morphological ontogeny of Neoseiulus cucumeris (Oudemans) based primarily on specimens reared in a laboratory at Manaaki Whenua – Landcare Research, Auckland, New Zealand. We describe all postembryonic stages and illustrate them in detail: the larva, protonymph, deutonymph (male and female), and adult female and male.

In this paper, we studied the morphological ontogeny of Neoseiulus barkeri Hughes (Acari: Phytoseiidae) based on specimens collected from Southwest University (Chongqing, China) and reared in laboratory of Shanxi Agriculture University.

This study contributes to the extensive history of research on the family Phytoseiidae in New Zealand, covering nearly a century. We examined phytoseiid specimens in the major repositories, unveiling fifteen species new to New Zealand: Amblyseius andersoni (Chant), A. waltersi Schicha, A. williamsi Schicha, Australiseiulus australicus (Womersley), Euseius elinae (Schicha), Graminaseius graminis (Chant), G. sturti (Schicha), Neoseiulus alpinus (Schweizer), N. californicus (McGregor), N. dieteri (Schicha), N. tareensis (Schicha), Proprioseiopsis anthurii (Schicha), P. cabonus Schicha & Elshafie, P. okanagensis (Chant) and Typhlodromus transvaalensis (Nesbitt), and clarifying the presence or absence status of some species in the country. Additionally, we analysed the diversity and distribution of species in New Zealand, presenting an updated checklist of phytoseiid species in the country.

The genus Neoseiulus in Shanxi Province is reviewed and seven species are recorded from the province. Four of these are redescribed and detailed taxonomic information are provided. Neoseiulus paraki (Ehara) is recorded for the first time in China and Neoseiulus neoreticuloides (Liang and Hu) is considered a new junior synonym of Neoseiulus bicaudus (Wainstein). Additionally, a diagnostic key to the known species of Neoseiulus in Shanxi is provided.
