Seta 11 in all Culiseta is rudimentary as is seta 13 and usually 14. All thoracic setae in Culicella larvae, unlike those in Culiseta s. str. and A. longiareolata, are smooth or have pubescence. Edwards (1930) noted the presence of especially small dendritic setae located dorsolaterally on the thorax and abdomen of Theomyia fraseri. Occasional attempts have been made to use the thoracic chaeto- taxy in the systematics of mosquito larvae. Our data indicate that differences among the individual groups of Culisetina, their subgen- era and genera, are perceptible. However, this is not so for species- wise differences, since thoracic chaetotaxy varies widely in each species and at the same time the variation is uniform in different species of the same subgenus (Siribaed, 1936). In other genera of the family Culicidae, which are very far apart, the nature of thoracic chaetotaxy may be similar to either Culiseta s. str. (in larvae with mixed feeding and periphytophages) or Culicella (in larvae of filter feeders). Similarity in thoracic chaetotaxy not only in the various species of the same subgenus, but in various genera often far removed from each other and, at the same time, critical differences in.
