Larva a salinarius-type? Dark gular region (and frontoclypeus?). Mentum with rounded teeth, centre tooth relatively broad and c2 teeth well separated (type II), fourth laterals only slightly reduced (type I-II).
Cytology
: 4 pairs relatively short chromosomes with the thummi
arm combination AB, CD, EF,
G. Centromeres recognizably heterochromatic.
Arm G with nucleolus near the centromere, followed by a constriction
and a large median
nucleolus; superficially similar to that of C. cucini.
Nucleoli in the long arms in both C and D; homologues often partially
unpaired. Closely
related to C. riihimakiensis.
Arm A1: 1-2c, 10-12, 3-2d, 9-4, 13-19
ie. as holomelas
Arm A2: 1-2c, 10, 8d-9, 2d-3,
12-11, 8c-4, 13-19
Arm B1:
Arm C1: 1-6b, 11c-8, 15-12, 11h-d, 6gh, 17a-16, 7d-a,
6f-c, 17(a)b-22 i.e. as pilicornis,
etc.
Arm D1: 1-3, 11-17, 8-4, 10-9, 18-24
Arm E1: 1-3e, 5-10b, 4-3f, 10c-13
ie. as aberratus,
cucini,
etc.
Arm F1: 1-10, 17-11, 18-23
ie. as
aberratus, riihimakiensis
1,
etc.
