Abstract In collections from 106 localities in New Zealand
and three from Australia, 19 species were found belonging to the genera
Criconema, Mesocriconema, Discocriconemella, and
Hemicriconemoides; eight species are new to science. Four new
species belong to the Criconema mutabile-group: C. acuticaudatum
n. sp., characterised by anterior vulva (81-85%), long postvulvar body part
(PV) (62-78 um), stylet = 69-78 um, and R = 88-95; C.
undulatum n. sp., characterised by anterior margins of the annules being
undulate, V = 87-90%, stylet = 78-87 um, R = 116-130, and PV =
45-67 um; C. alpinum n. sp., characterised by long stylet
(85-99 um), V = 87-90%, R = 84-91, and PV = 31-44 um; and C.
graminicola n. sp., which has the vulva rather anterior (82-88%), PV =
43-61 um, R = 73-86, and stylet = 62-81 um. The other four new
species are: C. magnum n. sp., with anterior margins of annules
undulate, body large (0.60-0.90 mm), postvulval part plump conoid,
terminus broadly rounded, R = 58-65, and stylet = 89-101 um; C.
lineatum n. sp., characterised by a deeply incised lateral line and spicate
tail, R = 67-73, and stylet = 77-89 um; C. cristulatum n. sp., with
minute hairs or spines on the outer edge of body annules and, at
<0.50 mm, shorter than both C. certesi and C.
racemispinosum; and C. aucklandicum n. sp., which has a continuous
fringe of minute hairs on the outer edge of body annules and differs from
related species in average body length (0.52 mm), stylet length
(89 um), and tail length (33 um). The 11 other taxa found were
Criconemoides parvus, Mesocriconema rusticum, M.
xenoplax, Criconema californicum, C. sphagni, C.
macilentum, C. spinicaudatum, C. sp. cf. pacificum,
C. pasticum, Hemicriconemoides cocophilus, and
Discocriconemella sp.
