IV. The Terrestrial Isopoda of New Zealand.

Abstract

THE first Terrestrial Isopoda clescribecl froiii S e w Zealand were tliosc given by DtLtIit * jii 1863, in his account of the Crustacea, collcctcd by thc United States Exploring Expedition ; in it he described and figured in considcrablc detail 7 species (including oiie clouhtfnl one), all of them from the northern part of Scm Zealand. In 1865 one or tn-o species were addcd by IIeller fin tlie rcport on the Crustacea of the Novara Expedition. I n 1576 Mr. E. J. Jfiers $ compiled a Catalogue of the New Zealaird Crustacea, ancl in connection therewith describcd soiiie new species that wcre in the collections of the British Musenru; hc added 5 specics, ancl his catalogue contains altogether 1 2 species and one considcred doubtful. Dwing subsequent years a few species i x r e acldcd by Jtr. G. 11. Tlionisoii 8 and inysclf 11, ttnd all the species knomn n-ere included in our " Critical List of the Crustaccs Jfalacostraca of Xew Zcalaiicl." 7 In 1885 B u d d c-L i d ** puhlislicd liis " Crustacca Isopoda Terrestria," ancl added two new species and meiitioncd most of tliosc previously described, hut as he was unable to examine specimens he could g i w no aclditional iuformation 011 them, and was obliged t o lem-e ser-era1 of t heiii uiider the licadiug of' " micertain specics.'' Four other nem species were described and figured by Filliol in 1883 in his " 3lission cle l'ile Campbell," f-fin which lie also grtve references to previously described species. I n the present papcr I endeavour to g i~e a coiiipletc list of all the New Zealand Terrestrial Isopoda at prcscnt known, with clcscriptions of the 1-arious species and figures where necessary. The material at illy disposal consists chiefly of collectioiis that I have accuiiiulated since 1S84. Besides specimens that I have collected myself, I have 111aiij-from Nr.

Biota of a subalpine springbrook in the Southern Alps

“…Two possible exceptions are the larvae of Zelolessica cheira and Conuxia girnni which characteristically are found on mosses in Pupu Springs (Michaelis 1977) and streams elsewhere (Cowley 1975). The isopod, Styloniscus oiakensis, is widely distributed throughout the South Island in damp situations (Chilton 1901) and has also been recorded under stones or wood and in forest on the Auckland and Chatham Islands (Stephensen 1927).…”

Catalogue of terrestrial isopods (Crustacea, Isopoda, Oniscidea) from Brazil: an update with some considerations

“…Nauplius, 26: e2018038 by the authors, it is clear that the specimens examined by Vandel (1952b) correspond to a different species from that described by Chilton (1901). Recently, the same morphological characteristics described by Vandel (1952b) were observed in specimens collected from Brazil (Lopes et al 2005;Zimmermann et al 2015a;present material).…”

“…Remarks. Chilton (1901) described Trichoniscus otakensis from South Island, New Zealand. The author mentioned that the buccal pieces, male pereopods and pleopods 1 and 2 were similar to T. phormianus [= Styloniscus p. (Chilton, 1901)] and did not describe them.…”

“…Chilton (1901) described Trichoniscus otakensis from South Island, New Zealand. The author mentioned that the buccal pieces, male pereopods and pleopods 1 and 2 were similar to T. phormianus [= Styloniscus p. (Chilton, 1901)] and did not describe them. Vandel (1952b), based on material from Omaio, east coast of North Island, New Zealand, placed the species in the genus Styloniscus and provided the description and illustrations of the sexual characters of the male, i.e., the pereopod 7 ischium distally enlarged, pleopod 1 exopod triangular and pleopod 2 endopod very long with tapering distal portion.…”

The terrestrial Isopoda (Crustacea, Oniscidea) of Rapa Nui (Easter Island), with descriptions of two new species

“…A similar character is present also in a species from Omaio, North Island, New Zealand, identified by Vandel (1952) as Styloniscus otakensis (Chilton, 1901). The specimens redescribed and illustrated by Vandel certainly do not belong to Styloniscus otakensis according to the redescription of this species provided by Green (1971) on the basis of the type material studied by Chilton (1901) and on topotypic material (Dunedin, South Island). In fact, the male pereopod 7 ischium does not show any distinct lobe (compare fig.…”
