margin shallowly concave, disk without sculpturing, not pubescent; scutellum 
not striate behind transverse sulcus. Forewing without a membrane, veins 
contrastingly black, with three anteapical cells of which base of innermost is 
distal to claval apex, base of middle one varying from distal to proximal to 
claval apex, and base of outermost proximal to claval apex; forewings of fe- 
male in rest position exceeding apex of ovipositor. Hindleg 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 with posterior margin broad- 
ly convex, with numerous macrosetae on posterior half; pygofer processes ab- 
sent. Plates triangular, tapering gradually, not extending posteriorly as far as 
pygofer apex, each with uniseriate macrosetae. Style extending posteriorly as 
far as apex of connective, acute apically. Aedeagus with basal apodemes 
shorter than shaft which extends posterodorsally and bears a pair of lateral 
tapering retrorse anteapical processes. Paraphyses biramous, symmetrical. 
Female abdominal sternum VII moderately produced and angular at apex; 
second valvulae of ovipositor narrow, each with ventral margin very slightly 
convex, bearing widely-spaced sloping teeth on dorsal margin beyond basal 
curvature, the teeth slightly closer together near apex, with minute secondary 
denticles located between the teeth but not posterodorsally nor posteroven- 
trally before the very acute apex. 
Laneola, new genus, is known only from the type-species of which I have 
seen specimens from Minas Gerais and Rio de Janeiro, Brazil. Laneola is 
similar in the second valvulae of the ovipositor and in some features of the 
male genitalia, to 7lagonalia, new genus, but it is doubtful that any close phy- 
letic relationship exists. The type-species is a beautiful green species with 
black lines on the crown and face and black veins on the forewings to their 
apical orange band. 
I am pleased to name this genus in honor of the late Dr. John Lane, well- 
known dipterist from Sado Paulo whose collections have been helpful in the 
course of this study.

Type-species: Cibra acuta, new species. 
Length 6.4-6.9 mm. 
Head well produced, anterior margin acutely angular in dorsal view, me- 
dian length of crown slightly less than interocular width and varying from 
slightly more than one-half to six-tenths transocular width, without a carina 
at transition from crown to face, ocelli on or slightly before a line between an- 
terior eye angles, each equidistant from median line and adjacent anterior eye 
angle or slightly closer to latter, crown without a concavity on disk, without 
sculpturing or setae, lateral clypeal sutures extending onto crown and attain- 
ing ocelli; antennal ledges not protuberant, in lateral view with anterior 
margins vertical; face without a vertical lenticular sclerite bordering lateral
