In C. annulata, C. alaskaensis and some other members of the subgenus Culiseta, the gonotelopod is fairly distinctly bifurcated and this bi- furcated portion is very long, giving the impression of two append- ages.

This is probably the explanation for Liu and Feng's report (1956) that C. kanayamensis* of northeastern China has two gono- telopod appendages. In Allotheobaldia Ion gi are ? lata this character distinctly differs from that known in Culisetina in that the former have not one, but two digitate appendages and they join toward the anterior end of the apical gonotelopod (Fig. 24, 7).. / 2 3 4 5 6 Fig. 24. Types (1-7) of gonotelopod appendages. Among other gonopleural sclerites, apart from the gonopod, Culisetina mosquitoes have paired gonepimerons and gonepister- nites forming the aedeagus accessories, that is, the levers associated with the phallus, which carry the ejaculatory duct. Homologs to coxopleural sclerites (corresponding to trochanters) could not be detected in Culisetina. The gonepimeron (gepm), often called the basal plate of the aedeagus, is in the form of a bent plate (Fig. 23) along with processes with which it joins the apodeme of the gono- coxite and the gonepisternite by joining at its depression. Thus, with this sclerite, muscle attachment is established between the gonocox- ites and the copulatory organ, the phallus. As we have noted, the gonepimeron of Allotheobaldia longiareolata loses its independence by growing inward with the apodeme of the gonocoxite into a broad plate (Fig. 23, ag and gepm). One of its processes, as in Culiseta, joins the gonepisternites for the protrusion and muscular move- ments of the gonocoxite and phallus. The other pleural sclerite of the ninth segment, the gonepister- nite (geps), also has the form of a plate, but it is situated not parallel,
