Diagnosis

The relative length of the third and fourth segments of the second antenna is a useful character for distinguishing this species from congeners. In most species of Odontomolgus the fourth segment of the second antenna is equal to or shorter than the third segment. Only in O. mundulus Humes, 1974b, is the fourth segment longer than the third. However O. mundulus, with the length of the female 1.90 mm (1.79-2.11 mm) and the length of the male 1.67 mm (1.60-1.79 mm), is much larger than this species. Moreover, in O. mundulus the second antenna in the male is sexually dimorphic, and the free segment of leg 5 in the female is smaller, 78 x 34 µm, with a ratio of only 2.29 : 1.
