Length of male 6.5-6.7 mm, of female 6.9-7.5 mm. Male pygofer with all 
macrosetae located close to apex; plates with macrosetae multiseriate but not 
numerous; aedeagus in ventral view with shaft short, with a transverse an- 
. teapical ridge from which a short curved acute process arises on each side, 
- and with a pair of recurved processes arising more dorsally. Face of male with 
_ clypeus and clypellus variably infuscate, from completely dark except for nar- 
_rowly yellowish lateral margins (holotype) to completely pale yellowish except 
for a large black spot at transition to crown, lora and genae varying from pale 
yellowish to mostly black.

males are mounted on the same point — the specimen at the tip of the point 
is the holotype. Also a male and female, Bafios, Ecuador, April 14, 1939, 1800

T. adunca, n. sp., can be separated from other species in the genus by the 
distinctive form of the aedeagus in the male, and from other species in which 
the female is known by the longitudinally fluted appearance of the disk of ab- 
dominal sternum VII.
