New species of Euptyctima (Acari, Oribatida) from New Zealand

Abstract

Oribotritia contortula n. sp., O.

Two new species of <i>Austrophthiracarus</i> (Acari: Oribatida: Phthiracaridae) from New Zealand

“…In A. hallidayi, (1b) interlamellar setae present; (2b) exobothridial setae vestigial; (3b) head of sensilli fusiform, narrow and slightly pointed distally; (4b) distance between rostral setae shorter; (5b) notogastral setae thinner and longer, c 1 /c 1 -d 1 =1.27; (6b) setae h 1 ' situated between ps 1 and h 2 ; (7b) four setae inserted at the ps 2 level; (8b) setae h of mentum longer than distance between them; (9b) setae ad 3 and ad 3 ' much longer than genital setae. This new species is also similar to New Zealand species Austrophthiracarus pulchellus Niedbała, 1993 in the presence of vestigial interlamellar setae, but can be easily distinguished from the latter species by the following nine characters (a versus b): in A. cronadun sp. nov., (1a) dorsal region of sigillar fields longer than lateral regions; (2a) head of sensilli much broader and truncate distally; (3a) exobothridial setae present; (4a) notogaster with 19 pairs of setae; (5a) notogastral setae longer; (6a) setae g 7 situated postero-lateral of g 5 ; (7a) setae h of mentum present; (8a) setae ad 3 and ad 3 ' minute, similar in length with genital setae; (9a) setae v'' on femora I present; in A. pulchellus, (1b) dorsal region of sigillar fields similar in length with lateral regions; (2b) head of sensilli rounded, but not truncate distally; (3b) exobothridial setae vestigial; (4b) notogaster with 18 pairs of setae; (5b) notogastral setae much shorter; (6b) setae g 7 situated at the level of g 4 ; (7b) setae h of mentum vestigial; (8b) setae ad 3 and ad 3 ' much longer than genital setae; (9b) setae v'' on femora I absent.…”

“…Before 1989, the fauna of ptyctimous mites in New Zealand was poorly studied, with only four recorded species (Ramsay 1966, Wallwork 1966, Luxton 1985. The total was later increased to 45 species-or over 10-fold increase-by Niedbała (1989Niedbała ( , 1993Niedbała ( , 1994Niedbała ( , 2000Niedbała ( , 2006 and Niedbała & Colloff (1997).…”

New Zealand species of <i>Oribotritia</i> (Acari: Oribatida: Oribotritiidae): descriptions of two new species and a key to eight species

“…This new species is similar to Oribotritia contortula Niedbała, 1993 in sharing the following features: one pair of lateral carinae present, similar shape of prodorsal and notogastral setae, eight pairs of genital setae and two pairs anal setae present, but the new species can be easily distinguished from the latter species by the following eleven characters (a versus b): in O. mangamuka sp. nov., (1a) colour yellowish; (2a) interlamellar setae directed backward; (3a) sensilli much longer (ss=175, ss/in=3.5); (4a) rostral setae situated close to each other (in-in/ro-ro=3.37); (5a) in=le; (6a) setae c p situated higher than insertion level of setae c 3 ; (7a) setae e 2 situated higher than insertion level of setae c 3 ; (8a) Etymology.…”

“…The genus has a nearly cosmopolitan distribution except the Antarctic Region. Till the end of 2012, 85 valid species of this genus were reported (Subías 2012), and among these, six species were known from New Zealand (Niedbała 1993(Niedbała , 2000(Niedbała , 2006Niedbała & Colloff, 1997). During the first author's visit to Landcare Research in Auckland in April 2012, we Article FIGURES 1-7.…”

The genus <i>Notophthiracarus</i> of New Zealand (Acari: Oribatida: Phthiracaridae): three new species and a key to 24 described species

“…Up to now, more than 140 species were included in this genus (Subías 2012). Prior to this work, 21 species belonging to this genus have been recorded from New Zealand (Ramsay 1966;Niedbała 1989Niedbała , 1993Niedbała , 2000Niedbała , 2006. During the first author's visit to Landcare Research in Auckland in April 2012, we identified three new species of this genus from New Zealand Arthropod Collection.…”
