than seven-tenths interocular width and from slightly more than one-third to 
slightly more than four-tenths transocular width, without a carina at transi- 
tion from crown to face, ocelli located before a line between anterior eye 
angles, each ocellus closer to median line of crown than to adjacent anterior 
eye angle, crown without a transverse concavity at ocelli (exception: Beirneola 
pensilis, n. sp.) and without a median longitudinal concavity (exception: B. 
albiceps (Fowler)), surface without sculpturing or setae; lateral clypeal sutures 
extending onto crown and attaining ocelli; antennal ledges not protuberant, in 
lateral view with anterior margins rectilinear and almost vertical; clypeus con- 
vex medially, muscle impressions not very distinct, transclypeal suture ob- 
solete at middle, clypellus distinctly produced with the contour of its lower 
portion more nearly horizontal than remainder of profile of face (exception: 
albiceps). 
Thorax with pronotal width less than transocular width of head, lateral 
margins slightly convergent anteriorly, dorsopleural carinae complete, disk 
without sculpturing or pubescence; scutellum not transversely striate behind 
transverse sulcus. Forewing without a membrane; veins not elevated, not very 
distinct, with three closed anteapical cells, of which the bases of the inner two 
are slightly and the outermost greatly proximal to a line drawn across wing at 
claval apex, with four apical cells of which the base of the fourth is usually 
more proximal than the base of the third, without an anteapical plexus of 
veins; forewings of female in rest position exceeding apex of ovipositor. Hind- 
leg with femoral setal formula 2:1:1, length of first tarsomere greater than 
combined length of two more distal tarsomeres, and with two parallel rows of 
small setae on plantar surface. 
Male genitalia: Pygofer moderately produced and moderately to strongly 
convex posterodorsally, with few to many (usually) macrosetae on posterior 
half to two-thirds of surface, occasionally with a number of interspersed 
microsetae, pygofer processes absent. Plates slender, triangular, not extending 
posteriorly nearly as far as pygofer apex, with macrosetae very few and 
located basad of midlength. Style extending posteriorly to a variable degree in 
relation to apex of connective, apex varying specifically from truncate to 
acute. Aedeagus with shaft directed ventrally, without processes, but with a 
short apicoventral angle in some specimens. Paraphyses with stalk slender and 
elongate, rami elongate, slender, and tapering, not symmetrical. 
Female abdominal sternum VII greatly variable interspecifically. Genital 
chamber with or without sclerites. Ovipositor with dorsal quadrate primary 
teeth on approximately apical two-thirds of portion of second valvulae beyond 
basal curvature; apex of second valvula rounded posterodorsally and with 
minute anteapical dorsal and ventral denticles not or scarcely visible (at 
160X). 
Specimens of Beirneola, new genus, are variable interspecifically in color. 
Beirneola ranges from Costa Rica to Ecuador. It is similar to Fusigonalia, new 
genus, in color pattern, and the latter contains species with a decurved 
aedeagus, but none with asymmetrical paraphyses, a characteristic of 
Beirneola.
