4): golden; marked by median light stripe of varying width, extending from PME to rear of the carapace; dark bands or rays extend towards undulating submarginal
light stripes where they terminate.
Forewing with scattered dark scales and two lines, medial and submarginal
, typical of Natada, though faint; medial line intersects a faint spot at end of discal cell; submarginal
line slightly concave to outer margin; stalk of [R.sub.3] and [R.sub.4] connects at junction of [R.sub.2] and [R.sub.5].
con 10 setas a lo largo del margen anterior.
Oral disc large, not emarginate, completely bordered by single row of marginal papillae; submarginal
papillae large, present at lateral tips of anterior and posterior tooth rows, becoming less numerous anteriorly and posteriorly, few extending along anterior margin of tooth row A1 (sinistral) or A2 (dextral); two rows of small submarginal
papillae present along posterior margin of oral disc, not extending anteriorly beyond level of tooth row P4; labial tooth row formula 4(4)/6, A1 shortest, A2-A4 of approximately equal length; A4 gap narrow; P1-P6 slightly shorter than anterior tooth rows, P1-P4 approximately equal in length, longer than P5-P6; P5-P6 intermittent; labial teeth in rows P4P6 shorter in height than those in other rows.
In his comprehensive review of New World Typhlocybinae, Young (1952) treated Empoascini as a junior synonym of Typhlocybini but Mahmood & Ahmed (1968) included the genera of Empoasca complex in the tribe Empoascini, and Dworakowska (1979) further refined the definition of Empoascini to accommodate genera lacking an appendix of the forewing and having the submarginal
vein in the hind wing reaching but not exceeding the vein RP+MP' or RP (Dworakowska 1979).
Color in alcohol pale, males with black submarginal
band in dorsal fin, caudal fin translucent.
Forewing 3.8-3.9x as long as wide; venation extending to about 0.6x length of wing, disc almost hyaline except infumate behind base of marginal vein, mostly bare behind base of submarginal
vein and densely setose elsewhere; the longest marginal seta 0.26-0.32x greatest width of disc.
2) Hind wing dorsal surface with structurally coloured distinct submarginal
lunules in spaces between veins CuA and CuA2; ventral hind wing abdominal fold black without pattern in basal and subbasal areas (Venezuela) (Figs.
6), 4.10 long, 3.50 wide, brown, darker on cephalic area, with indistinct submarginal
lighter bands that do not extend posteriorly, three light spots on each lateral margin (Fig.
The distal part of the valve, as far as its upcurving section, is with a continuous series of relatively long, fine setules, arising slightly submarginally but extending well beyond margin of posterior-ventral angle, then becoming submarginal
suddenly and continuing dorsally as a distinct row nearly straight, not parallel to posterior margin.
Vena marginal ligeramente mas corta que la vena submarginal
, con 9 setas a lo largo del margen anterior; vena submarginal
con 6 setas delgadas mas largas.
caraca; 2) dorsal forewing triangular spot in Cu[A.sub.2]-2A is ochreous in males of T maacki while larger and yellowish in T caraca; 3) ventral forewing submarginal
bright yellow band from apex, wide, continuous, extending to [M.sub.3] and fusing with [M.sub.1]-[M.sub.3] submarginal
hyaline spots in T.
