connective, rounded apically, with a number of microsetae on apical half, 
without a preapical lobe. Connective narrowly Y-shaped, with stem longer 
than arms. Aedeagus slender, curved gradually dorsad and gradually 
narrowed to acute apex, gonopore anteapical and ventral. Paraphyses absent. 
Female abdominal sternum VII with apical margin concavely emarginate 
medially; pygofer with macrosetae grouped parallel to and near posterior 
margin. Genital chamber without sclerites in the membrane. Second valvulae 
with dorsal margins not strongly convex, toothed only on apical half, the teeth 
poorly defined at base of toothed portion, irregular but larger and bearing 
minute secondary denticles in more apical portion of dorsal margin, each 
valvula gradually tapered to narrowly rounded apex, with anteapical dorsal 
and ventral denticles. 
Specimens of Torresabela fairmaire: (Signoret), the only known species, are 
dark red with the ground color of the pronotum and large spots on forewings, 
yellow. The species occurs on Nymphaea sp. 
Torresabela, new genus, is placed in the Erythrogonia generic group, within 
which it forms a complex with the new genera Aguahua, Kapateira, and 
Nielsonia. The concave posterior margin of abdominal sternum VII of the 
female will separate Torresabela readily from these genera.

Type-species: Tettigonia salamandra Signoret (1855d:787). 
Length 9.0-10.1 mm. 
Head slightly produced, median length of crown varying from one-half to 
almost seven-tenths interocular width and from approximately one-third to 
slightly more than four-tenths transocular width, anterior margin broadly 
rounded in dorsal view, without a carina at transition from crown to face, 
ocelli located behind a line between anterior eye angles, each slightly closer to 
adjacent anterior eye angle than to median line of crown, crown with a trans- 
verse concavity across ocelli, surface without sculpturing or setae, lateral 
clypeal sutures extending onto crown and attaining ocelli; antennal ledges not 
protuberant, in lateral view with anterior margins oblique and convex; 
clypeus convex, muscle impressions distinct, transclypeal suture obsolete 
medially, clypellus in profile with its lower portion more nearly horizontal 
than remainder of face, densely pubescent (but often rubbed). 
Thorax with pronotal width less than transocular width of head, lateral 
margins parallel, dorsopleural carinae almost complete, posterior margin 
shallowly concave, disk transversely rugose, not pubescent; scutellum not 
transversely rugose behind transverse sulcus. Forewing with membrane in- 
cluding only inner apical cell, veins elevated and distinct, with three closed
