Description. Dorsal surface reddish-castaneous, abdominal venter reddish-castaneous to castaneous. Apex of humeri yellow. Rostrum attaining fifth sternite.

Male. Measurements (n = 2). Total length 16.50- 17.75; head length 3.22-3.34; width 3.56-3.63; eye width 0.91-0.94; interocular distance 1.81; anteocular length 1.50- 1.56; antennal segments I, 1.03-1.16; II, 1.63-1.69; III, 2.19- 2.25; IV, 3.94-4.00; V, 3.94; pronotal length 3.88-4.38; width 14.19-16.38; scutellum length 7.25-7.88; width 6.19-6.75; corium length 10.25-10.50; abdominal width 9.00-10.00.

Genitalia. Pygophore subtrapezoidal, almost quadrangular, globose in ventral view ( fig 11 View Figs ). Proctiger trapezoidal, sligthly wider basally, with a tumid area at the apical third ( fig. 5 View Figs ). Parameres distally thin ( fig. 14 View Figs ), apex slightly curved laterad ( fig. 8 View Figs ). Posterolateral angles rounded, mutic. Ventral rim: median process inconspicuous; lateromedian processes well-developed, truncate and blackish, delimiting a median V-shaped excavation ( fig. 11 View Figs ). Phallus ( figs. 17, 20, 23 View Figs ): basal plate well-developed, half as long as phallotheca. Visible part of processus phallothecae about half of the length of phallotheca. Vesica well-developed, with one median, ventral process. Ductus seminis distalis (dsd) long, surpassing conjunctiva and distally curved back inward it. Conjunctiva well-developed, with two pairs of processes: one basal (prcj1), directed dorsad and one more apical, finger-like (prcj2), turned towards prcj1.

Female unknown.

Type material. Holotype, BRASIL, Pará: Oriximiná ( bacia do Cuminá-Miri ), 19-26.I.1968, Exp. Perm. Amaz. ( MZSP) ; paratype, PERU, Rio Santiago, 6.XI. [19]28, F 6198, H. Bassler Collection Acc. 33591, Taurocerus edessoides (Spin.) ( AMNH) .

Comments. This species is very similar to T. edessoides, from which can be distinguished only by genital characters, as the parameres laterally directed and ventral rim of pygophore with truncate latero-median and an inconspicuous mesial tubercles.
