83. Genus HELOCHARINA MELICHAR 
Ficures 498, 499 
Helocharina Melichar, 1926a:343. Type-species: Tettigonia gay: Spinola, by subsequent 
designation of China, 1938d:184. 
Length of male 6.0-6.3 mm, of female 6.4-6.8 mm. 
Head moderately produced, with median length of crown from slightly 
more than one-half to three-fourths interocular width and from one-third to 
almost one-half transocular width; anterior margin narrowly rounded in dor- 
sal view, not angulate or carinate at transition from crown to face, ocelli on a 
line between anterior eye angles, each approximately equidistant from median 
line of crown and adjacent anterior eye angle, surface shallowly concave be- 
tween ocelli or not and often with a few punctations near ocelli, lateral clypeal 
sutures extending onto crown but not attaining ocelli; antennal ledges not 
protuberant, in lateral view with their anterior margins convex and oblique; 
face in profile slightly convex, clypeus flattened medially or not, median area 
punctate or not, transclypeal suture indistinct medially, lower portion of 
clypellus more nearly horizontal than upper portion or continuing profile of 
clypeus, face without pubescence. 
Pronotum with width less than transocular width of head, lateral margins 
parallel, dorsopleural carinae complete, posterior margin concave, disk trans- 
versely rugose, not punctate, without pubescence; scutellum usually weakly 
transversely rugose behind transverse sulcus. Forewing with membrane in- 
cluding only inner apical cell, veins distinctly contrastingly paler than remain- 
der of wing, venation at apex variable interspecifically, with or without an an- 
teapical plexus of veins, texture coriaceous, basal portion not punctate, wings 
of female in rest position exceeding apex of ovipositor. Hindleg with femoral 
setal formula 2:1:1; first tarsomere with length approximately equal to com- 
bined length of two apical tarsomeres, with two parallel rows of small setae 
on plantar surface. 
Male genitalia: Pygofer moderately produced and rounded posterodorsally, 
without processes, with a number of macrosetae on apical half. Plates slender, 
triangular, extending posteriorly as far as or farther than pygofer apex, with 
chaetotaxy variable interspecifically. Style extending posteriorly beyond apex 
of connective, with a distinct preapical lobe. Connective Y-shaped or trape- 
zoidal. Aedeagus short, regularly curved posterodorsad, without processes. 
Paraphyses Y-shaped, symmetrical or not (variable interspecifically ). 
Female abdominal sternum VII with posterior margin moderately to very 
strongly produced posteriorly. Genital chamber without sclerites. Ovipositor 
with dorsal sloping primary teeth occurring on margin beyond basal curva- 
ture, the teeth fairly close together in apical half, variable interspecifically 
nearer base, each of the primary teeth bearing a number of secondaries, apex 
of each second valvula narrowly rounded and with minute anteapical dorsal 
denticles. Pygofer moderately produced, gradually or abruptly rounded 
apically, with a number of macrosetae on apical half. 
Helocharina Melichar is known from the type-species and the new species 
described below, both from Chile. Specimens available to me have been
