short macrosetae on posterior two-thirds; plates not extending as far 
posteriorly as pygofer apex; style extending posteriorly approximately as far 
as apex of connective which is Y-shaped with arms widely divergent and stem 
broad; aedeagus with shaft slighty decurved, gonopore located basidorsally, 
greatly exceeded by apex of shaft which bears a slender unpaired ventral ante- 
apical elongate process which is directed ventrally, and a pair of very short 
dorsoapical triangular processes; paraphyses long-stalked with rami slender 
and tapering to acute apices. 
Ground color of crown, pronotum, and scutellum, sordid yellow to brown, 
with a broad lateral oblique stripe on each side of crown, in some specimens 
extending to apex, the two stripes then contiguous apically, each of the stripes 
continuing onto pronotum and forming a lateral submarginal border, a me- 
dian triangular pronotal marking at middle of posterior margin, its apex ex- 
tending forward onto disk, and scutellum with an anteapical spot, red; fore- 
wing black, clavus with one or two red spots opposite humeral margin, a 
transcommissural stripe across clavus before its midlength, extending laterally 
to claval suture and forward along inner margin of latter and an anteapical 
transcommissural spot, red; corium with four small spots in an oblique line 
parallel to claval suture and with four spots along costal margin, the 
posteriormost often divided, red, posteriormost costal spot with a contiguous 
triangular hyaline area before and behind and often with one or more small 
circular hyaline spots bordering posterior margin; with a small hyaline area 
bordering concave apical margin; face, propleura, and legs, yellow.

(J. Zetek), and a long series of specimens from La Ceiba, Honduras; San 
Marcos, Turrialba, and ‘‘Waldeck’’, Costa Rica; numerous localities in Pan- 
ama; Bartica, and Essequebo River, British Guiana; ‘“‘Vera Paz”’, Guatemala 
(on cacao); San Esteban, Venezuela; and Los Rios, Ecuador (USNM). Also 
from Costa Rica (on sweet lemon); San Isidro del General, Costa Rica; and 
“Colombia” (NCS); from Bogota, Colombia (RMS); from Nayarit, and 
Chapingo, D. F., Mexico, and San Salvador, El Salvador (OSU); from Mara- 
cay and Caracas, Venezuela (SSM); from Paramaribo, Surinam (ZIMH); 
from ‘“‘Surrubres’’, Costa Rica (MMB); from Bolivar, Colombia (ZIL); and 
from Chiapas, Mexico (CAS). 
L. sannionis, n. sp., can be readily separated from other species in the genus 
by the distinctive form of the aedeagus. L. sannionis may be separated exter- 
nally from other species with a somewhat similar color pattern of crown and 
pronotum, by the midclaval transverse red line which runs forward along the 
claval suture in sannionts. 
This is the species Fowler (1900a:262) interpreted as Tettzgonia sanguinolenta 
Coquebert.
