Head relatively narrow, mentum width only about half the VHL. Mentum (Fig. c) with 4th lateral only slightly reduced (i.e. between type I and II); centre trifid tooth with a relatively broad, squared off c1 and distinct c2 teeth (i.e. type II).Cytology: 3 polytene chromosomes, modified pseudothummi arm combination (BF, CD, GEA). Arm G is attached to arm E by a loose nucleolar connection, but the reality of this connection is confirmed by the presence of only six chromosomes in mitotic metaphases. The nucleolus in arm F is either reduced or absent.
Ventromentum (Fig. d) with about 43 striae on only specimen counted. Pecten epipharyngis (Fig. a) with about 14-17 rather uneven teeth.
Basal segment of antenna (Fig. b) relatively long and narrow, about 4 times as long as wide; 4th segment relatively short, only about 20% longer than segment 3.
Mandible (Fig.e) with 3rd inner tooth darkened and almost completely separated (i.e type II, tending to type III); about 18-20 grooves on outer surface near the base.
Arm A has the sequence, derived from A4 by a simple inversion, found in C. novae-zelandiae (nzlA2). Arm E appears identical to oppositus E1, while arm F differs from F1 of C. zealandicus by an inversion of about the region from 11-9e.
One poor specimen appears to be heterozygous in one chromosome arm, but the arm could not be identified.Arm A1: 1a-e, 11 - 10, 2c - 1f, 3e - 2e, 7 - 4, 12a-c, 3i-f, 9 - 8, 2d, 13 - 19 ie. as A2 of novae-zelandiae
Arm E1: 1 - 3e, 10b - 3f, 10c - 13 ie. as E1 oppositus(appears no more than 1 band missing)
Arm F1: 1 - 2a, 10 - 9f, 11 - 9e, 12 - 15c, 2c - 7, 2b, 15d - 23
Arm G1: with terminal nucleolus (attached to arm E) and a BR near distal end.
