A large single or more rarely two- or three-branched mandibular seta 19 (maxillary seta of Marshall, 1938) stands out prominently. Its maximum length and strength is in Allotheobaldia longiareolata. 61 Among the other structural elements of the maxillary lobe are the two well developed digitate appendages set alongside each other on the ventral median rib, almost at the very apex, in all Culiseta (Fig. 41). In A. longiareolata, these digitate appendages are situated not on the median rib, but on the inner surface close to the maxillary base (Fig. 42, 0). The maxillary palp (Fig. 41, mxp) is well developed in the peri- phytophages and larvae with mixed feeding (Fig. 42,1-3) but not so in the filter feeders (Fig. 42, 5). Apically it bears one, two or more, often three terminal sensory setae, and usually an indistinguishable.
