FAM. GELECHIAD/E IOI 
I04. GENUS SYMPHANACTIS, NOV. GEN. 
Tyne : S. helaera, Meyrick. 
Characters. — Head smooth; ocelli posterior; tongue developed. Antennae 5/6, in cf rather 
thick, simple, basal joint elongate, rather swollen towards apex, without pecten. Labial palpi long, 
curved, ascending, second joint somewhat thickened towards apex, terminal joint longer than second, 
slender, acute. Maxillary palpi rudimentary. Posterior tibiae clothed with long hairs above. Forewings 
with r? furcate, 2 from towards angle, 3 and 5 connate from angle, 4 absent, 6 and 7 out of 8, 7 to costa, 
11 from middle. Hindwings 2/3, narrow-trapezoidal, apex long-produced, acute, termen sinuate- 
emarginate, cilia 4; 3 and 4 connate, 5 curved, rather approximated to 4, 6 and 7 stalked. 
Remarks. — Correlated with TA:?otricka. 
Geographical distribution of species. — South American.

Thiotricha, Meyrick, Trans. N. Zeal. Inst. Vol. 18, p. 164 (1886). — Type : T. thorybodes, Meyrick. 
Reuttia, Hofmann, Iris, Vol. ro, p. 228 (1897). — Type : T. subocellea, Stephens. 
Characters, — Head smooth; ocelli posterior; tongue developed. Antennae 4/5, in c serrate, 
with long fine ciliations (3-6), basal joint elongate, without pecten. Labial palpi long, recurved, smooth- 
scaled, second joint hardly thickened, terminal joint as long as second or longer, slender, acute. 
Maxillary palpi rudimentary. Posterior tibiae clothed with long hairs above. Forewings with 1? furcate, 
2 from towards angle, 4 absent, 6 out of 8 or separate, 7 absent, 9 approximated or out of 8, r1 from 
beyond middle. Hindwings 1 or under r, elongate-trapezoidal, apex more or less produced, pointed, 
termen emarginate, cilia 1 1/2-6; 3 and 4 connate, 5 bent, approximated, 6 and 7 stalked. 
Remarks. — The long antennal ciliations of cf are a constant feature, very unusual in this 
family. The species are often elegantly marked, sometimes with orange or rosy colouring. The genus 
is correlated with PolyAhymno. 
Geographical distribution of species. — Characteristically Indo-Malayan, with a considerable 
Australian section (mainly Queensland), and scattered elements in Europe, Africa, South America and 
New Zealand. 
Larva (3 known) always feeding in a portable case (very exceptional in this family) on flowers, 
seeds, or leaves.
