(Figs. 6, 9, 12, 15, 18, 21, 24, 26, 28)
Arvelius edessoides SPINOLA, 1837:347.
Taurocerus hector STÅL, 1862:108; 1872:47; WALKER, 1867:391 (list).
Taurocerus edessoides; DALLAS, 1851:302 (list); DISTANT, 1880:82, pl. 7, fig. 25 (list); Stål, 1872:47; LETHIERRY & SEVERIN, 1893:185 (cat.); KIRKALDY, 1909:150 (cat.).
Type-locality. Brazil.
Type material. Lectotype and paralectotype, here designated. The material belongs to Spinola’s collection, at present deposited at MRSN. A green label in the box, containing the following data: Arvelius edessoides Spin., G. taurocerus, A. et S., D. Bouquet, Brésil.
Type material of T. hector examined. Stål described this species based on two males from Mexico and one female from unknown locality. We received from NHRS three males labeled as “ typus ” (loan number 1068/99) and “ paratypus ” (numbers 1069/99 and 1070/99), the last one collected in Bogotá [Colombia] by Alexander Lindig. We believe that the specimen 1070/99 is not actually a syntype of T. hector and the female mentioned in the Stål’s original description is missed. Then, we here designate as lectotype and paralectotype, respectively: 1, labeled: a) Vera Cruz [handwritten]; b) Hector Typ. Stål [handwritten]; c) Sallé; d) Typus [red label]; e) Naturhistoriska Riksmuseet Stockholm Loan no 1068/99; 1, labeled: a) Mexico; b) Stål; c) Hector Typ. Stål [handwriting]; d) Paratypus; e) Naturhistoriska Riksmuseet Stockholm Loan number 1069/99.

Genitalia. Gonocoxites 8 triangular, about one and a half wider than long (fig. 26). Sutural borders of gonocoxites 8 convergent, contiguous at apical half. Posterior borders concave near laterotergites 9. Laterotergites 9 narrow at apex. Secondary thickenings of gonapophysis 9 ear-like (fig. 28).

Comments. The color of the specimens varies from reddish to dark reddish-castaneous; the length of humeri is also variable, but the apices are always yellowish. The size and the triangular shape of gonocoxites 8, combined with the color of humeri distinguish T. edessoides from T. achilles and T. abruptus.
