Females (n=11), mean (with range) given for available specimens. Length of body: 21.27 (19.10–22.76); length of fore wing: 29.82 (26.66–31.54); width of fore wing: 9.26 (8.08–9.92); length of head: 3.82 (3.34–4.16); width of head including eyes: 9.13 (8.14–9.72); width of pronotum including suprahumeral plates: 8.45 (7.06–9.00); width of mesonotum: 7.02 (6.10–7.50).

Notes.— Mexico is now known to have 31 species and two subspecies of Diceroprocta Stål. This species is most similar to D. virgulata (Distant) superficially as D. virgulata is also characterized by infuscations of the distal portions of the tegmina and wings ( Distant 1904). The two species can be separated quickly by the triangular shape of the opercula, the opercula extending to the middle of sternite III, the opercula meeting medially and the fuscus stripe found along the midline of the opercula in D. oaxacaensis . In contrast, the opercula of D. virgulata do not meet medially, have oblique medial and lateral borders, have a subtruncate posterior margins and do not reach the base of the abdomen ( Distant 1904).
