The only specimen from Mexico is not included in the type series because of its darker pedicel and legs, especially the hind tibia, which is dark brown. Females, and especially males, of this species are very similar to those of N. nearctica (see the key for main differences). Netomocera meridionalis sp. nov. seems confined to Florida and neighbouring states, except for three specimens collected in Missouri. Its area of distribution seems to be shared to a certain degree with N. nearctica (mostly Missouri, Georgia and Texas), the records of N. nearctica in Florida being very rare (see below). As for N. nearctica , this species has both brachypterous and macropterous females; the ratio of brachypterous versus macropterous females among the analyzed specimens was 28:6, without obvious intermediate forms and thus opposite of the situation found in N. nearctica , where the macropterous form seems dominant.
