well beyond pygofer apex, each with numerous scattered microsetae. Style ex- 
tending posteriorly beyond apex of connective, tapered and acute apically, 
without preapical lobe. Connective broadly Y-shaped. Aedeagus with shaft 
flattened and erose anteapically. Paraphyses inconspicuous, symmetrical. 
Female unknown. 
Naltaca is known only from the type-species, from the mountainous south- 
ern portion of the state of Puebla, Mexico. It is similar in appearance to 
specimens of Plummerella DeLong, but may be distinguished readily by the 
lateral clypeal sutures which do not extend onto the crown, by the 2:1:0 
femoral setal formula of the hindlegs, the chaetotaxy of the male plate, and by 
the symmetrical paraphyses.

Type-species: Tettigonia costaricensis Distant. 
Length of male 6.1-10.2 mm, of female 6.5-10.9 mm. 
Head well produced, anterior margin bluntly subangular in dorsal view, 
without a carina at transition from crown to face, ocelli closer-to median line 
of crown than to adjacent anterior eye angle, located on or behind a line be- 
tween anterior eye angles (varying interspecifically), with area between ocelli 
flattened but not distinctly concave, without a median fovea, surface of disk 
longitudinally striate, without setae, lateral clypeal sutures extending onto 
crown and attaining ocelli; antennal ledges not or only slightly protuberant, 
in lateral view with anterior margins oblique and either convex or rectilinear 
(varying interspecifically); clypeus convex medially, muscle impressions dis- 
tinct or not, without a lenticular sclerite bordering lateral clypeal suture on 
each side below eye, transclypeal suture obsolete medially, clypellus not 
produced, contour of its upper portion continuing profile of clypeus, its lower 
portion curved more strongly posteriorly, clypellar apex weakly pubescent. 
Thorax with pronotal width equal to or greater than transocular width of 
head, lateral pronotal margins convergent anteriorly, dorsopleural carinae 
complete, disk transversely rugulose, not pubescent; scutellum transversely 
rugose or not behind transverse sulcus. Forewing with membrane including
