117. Genus ALLOGONIA MELIcHAR 
FiGuREs 671-677 
Allogonia Melichar, 1926a:343. Type-species: Tettigonia concinnula Fowler, by subsequent 
designation of China (1938d:184). 
Length 5.3-7.5 mm. 
Head well produced, median length of crown from two-thirds of to slightly 
greater than interocular width, and from four-tenths to six-tenths transocular 
width, without a carina at transition from crown to face, ocelli located on or 
behind a line between anterior eye angles, with relative distance of each 
ocellus from median line of crown and adjacent anterior eye angle variable 
interspecifically, crown shallowly concave before ocelli, with or without a me- 
dian fovea, usually with numerous irregularly arranged minute lenticular 
impressions as in Amphigonalia, new genus (exception: completa (Fowler)), but 
not as distinct, setae absent, lateral clypeal sutures extending onto crown but 
usually not attaining ocelli; antennal ledges not protuberant, in lateral view 
with anterior margins vertical (A. concinnula (Fowler)) or oblique and recti- 
linear; face usually without a vertical lenticular sclerite bordering lateral 
clypeal suture on each side below eye (very narrow when present), clypeus 
usually flattened medially, muscle impressions distinct or not, transclypeal 
suture obscure medially, clypellus with profile of its upper portion continuing 
contour of clypeus, its lower portion slightly more nearly horizontal. 
Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae complete, posterior 
margin concave, disk of pronotum transversely rugose or not, not pubescent; 
scutellum transversely striate or not behind transverse sulcus. Forewing with 
at least inner apical cell membranous, veins elevated and distinct (exception: 
completa), with three closed anteapical cells of which the bases are proximal to 
a transverse line across the claval apex, without or with only one or very few 
supernumerary crossveins in anteapical cells; forewings of female in rest posi- 
tion exceeding apex of ovipositor. Hindleg with femoral setal formula 2:1:1; 
length of first tarsomere greater than combined length of two more distal tar- 
someres and with two parallel rows of small setae on plantar surface. 
Male genitalia: Pygofer moderately produced, apex broadly rounded or 
truncate (A. indutula, n. sp.), with a number of macrosetae of varied size on 
posterior half; pygofer processes absent. Plates short, triangular, not extending 
posteriorly nearly as far as pygofer apex (exception: indutula), with uniseriate 
macrosetae. Style usually not extending posteriorly as far as apex of connec- 
tive, narrowly rounded or truncate apically, without preapical lobe. Aedeagus 
symmetrical or very nearly so (exception: completa), shaft varying interspeci- 
fically, with or without processes. Paraphysis a short symmetrical (exception: 
indutula) median sclerite near aedeagal base.
