Summary and conclusions
-
1.
The chromosome numbers of 51Miridae and nineNabidae (Hemiptera-Heteroptera, Cimicoidea) are given.
-
2.
InMiridae, Deraeocorinae, Bryocorinae andMirinae have a type 2n=34 and Phylinae 2n=32. Dicyphinae has 2n=48 and Orthotylinae 2n=24. The basic mirid caryotype is 32A+X+Y.
-
3.
The caryotype ofDicyphinae supports the view that the group warrants subfamily status.
-
4.
Phylus melanocephalus (2n=18) is unique amongst the mirids examined and could perhaps be retaining a primitive pro-mirid chromosome number.
-
5.
InNabidae, Nabinae have a type 2n=18.
-
6.
The species pairNabis rugosus andN. ericetorum are characterised by the same kind of deviation from family caryotype.
-
7.
Himacerus mirmecoides has double the family complement of autosomes.
-
8.
The basic cimicoid caryotype is, it is suggested, 2n=16A+ X+Y.
