Maskell’s first description of
K. parva
was very brief (
Maskell 1897
). His second description (
Maskell 1898
) had more detail but the illustrations were deemed “quite useless” by
Green (1915)
, who redescribed it and illustrated the adult female, 2nd-instar and 1st-instar nymphs.
Genus diagnosis
based on the descriptions of
K. parva
by
Green (1915)
and of
K. obscurata
(Maskell)
by
Ferris (1919)
and with examination of one original Maskell slide each of
K. obscurata
and
K. parva
(NZAC) (both mature, sclerotised females), compared with 4 young female
K. kiwiana
sp. nov.
Diagnostic features for the adult females in this genus are: (i) the apparently unique invaginated 5-locular disc pores on dorsum and/or venter; (ii) opening of microtubular duct a large dark ring on dorsum, that may appear as an empty invagination when derm heavily sclerotised and duct not visible (as on
K. obscurata
, see
Ferris (1919))
; (iii) ventral anal opening either simple or with a non-cellular anal ring, with 0–6 small setae; (iv) dorsal abdominal segments heavily sclerotised with intersegmental furrows; (v) antennae much reduced, with or without setae, and (vi) legs, when present, represented by vestigial leg flaps (
Williams 1985
).
Comments
.
Kuwanina
currently contains two species,
K. parva
and
K. obscurata
. The addition of
K. kiwiana
sp. nov.
brings this number to 3 and the distribution of the genus now includes
New Zealand
.
K. parva
has been recorded from
Korea
,
Japan
, and
United Kingdom
and
K. obscurata
from
Australia
(
Hoy 1963
,
Williams 1985
,
Miller & Gimpel 2007
).
Williams (1985)
indicated that
K. parva
seems to be related to
Cryptococcus
in lacking legs and having the metathoracic legs replaced by pore-bearing flaps;
Kuwanina
differs, however, in lacking macrotubular ducts.
Ferris (1919)
stated that
K. obscurata
has a cribriform plate or tubercle behind each posterior spiracle but this is in fact a pore-bearing leg flap (coxa) as on
K. parva
. Note that the illustrations of the adult female
K. parva
in
Green (1915)
and
Morrison & Morrison (1922)
show 3 pairs of anal ring setae, but the adult female specimen in NZAC, mounted by Maskell, clearly has only 2 pairs of anal ring setae, with other anal lobe setae in close proximity. It is uncertain whether this number is variable (unlikely), the Maskell specimen is aberrant, or earlier workers misidentified which setae were actually on the anal ring and thought there should be the normal 3 pairs of setae there.
K. kiwiana
sp. nov.
possesses 3 pairs of anal ring setae while
K. obscurata
has no setae on its simple anal opening.
