Meyrick, vol. 1, p. 86.
Distribution: Philippine Is.
Material examined: Luzon, Mt. Makiling (Baker), 1 9, topotype
and second specimen known (USNM). An extremely large species.
Diploclasis, new genus
Head ^\Titli appressed scales, side tufts moderately spreading.
Ocellus posterior. Proboscis developed. Antenna 4/5, in male
long-ciliated throughout, scape elongate, ^^-ith a brushy long pecten
along basal half. Labial palpus very long, porrected-recurved,
median segment very long, little ciu'ved, smooth, moderately thickened
before apex, terminal segment slender, acute, 2/3 median, rising.
Maxillary palpus moderate, pending, appressed to proboscis. Thorax
smooth. Posterior tibia smooth.
Forewing elongate, without tufts of scales on siu"face. Vein lb
furcate, 2 from before angle, 3 and 4 approximated, from angle, 7 and
8 stalked, 7 to termen just below apex, 11 from middle. Hindwing
elongate-semioval, under 1, ciha 1/2; 3 and 4 connate, 5-7 tolerably
parallel, 5 submedian, 6 and 7 running close along basal third.
Male genitalia as described with the species.
Type species: Diploclasis balbidophora, new species.
Probably allied with Tanyzancla Meyrick, but differing by long
ciliate antennae in male, very long median segment of palpus and
entnely smooth posterior tibia.
