Emended diagnosis.

: ligula with 5–6 teeth.
Remarks.
Generic diagnoses are given by
Roback (1971)
and
Murray & Fittkau (1989)
for the adult; and
Roback (1977)
and
Fittkau & Murray (1986)
for the pupa. The diagnoses in
Roback (1977)
,
Fittkau & Roback (1983)
and
Cranston & Epler (2013)
for the larva should be emended to accommodate the Neotropical species with an unusual feature for the genus. Concerning the
Tanypus
pupa,
Fittkau & Murray (1986)
wrote, “anal lobe reduced, generally slightly broader than long and shorter than segment VIII.” The pupa of the species treated here, however, has well-developed anal lobe, which is much longer than the abdominal segment VIII. The male genital sac is shorter than the anal lobe, and the relative length is much shorter than in

(see
Roback 1977
, figure 70;
Fittkau & Murray 1986
, figure 5.38 F). These features may change the concept of the
Tanypus
pupa. This genus is divided into two subgenera,
Apelopia

and
Tanypus

(
Roback 1971

).
Cranston & Epler (2013)
, however, noted that the genus cannot be separated yet in the larval stage.
