In male mosquitoes, a descriptive term applied to a variably shaped lobe arising mesally at the base of the gonocoxite; homologous with the basal mesal lobe. See genitalia.
In anopheline mosquitoes, the claspette is often divided into a dorsal lobe (Syn.: dorsal claspette, external lobe, outer lobe, ventral lobe) and a ventral lobe (Syn.: dorsal lobe, inner lobe, ventral claspette). The dorsal lobe in some species is more or less divided so that in addition to the ventral lobe there is a middle lobe (Syn.: median lobe) and a dorsal lobe (Syn.: ventral lobe). In species of the subgenus Nyssorhynchus, the ventral lobes are fused, = median lobe. The latter usually bears a small basal lobule (Syn.: lobule) on either side that may be homologous with the middle lobe.
