Diagnosis. H. pseudobutleri is characterized by the wide and reddish brown oblique submarginal line of forewing and the medial line of hindwing, and forewing without darkish shade distal to medial band. This species can be recognized by the following characters in male genitalia: narrow valva, saccular process strongly curved outwards, left process is short and the right process is slender, vesica with some flakes at basal part and a sclerotized, thick, hook-like process at distal part.

Externally, H. pseudobutleri sp. nov. is similar to H. butleri (Leech) ( Figs. 6 , 10 ), but the ground color is darker in H. pseudobutleri ; the submarginal line of forewing and the medial line of hindwing are both wider in H. pseudobutleri than in H. butleri ; the color of the submarginal line is reddish brown in H. pseudobutleri , in H. butleri , the color of the submarginal line is blackish brown; the dark shade exterior to the submarginal line is absent in H. pseudobutleri , it is present in H. butleri ; the hindwing with discal spot obscure in H. pseudobutleri , the discal spot on hindwing is well expressed in H. butleri . In male genitalia, valva is narrow in H. pseudobutleri , valva is broad in H. butleri ; the saccular process is short and strongly curved in H. pseudobutleri , the saccular process is long and stick-straight in H. butleri ; the vesica with some flakes and a sclerotized and hook-like process in H. pseudobutleri , a short, membranous process and a long, tubular process on vesica in H. butleri .

H. pseudobutleri new species also resembles H. hainana sp. nov., but can be separated from the latter by the following characters: the ground color is brown; the color of the submarginal line of forewing and medial line of hindwing are darker in H. pseudobutleri ; the dark shade exterior to the submarginal line is absent in H. pseudobutleri , it is present in H. hainana ; the reniform stigma is clearly marked in H. pseudobutleri , the stigma is vague in H. hainana ; the valva is narrow and the saccular process curved and slender in H. pseudobutleri , valva is broad and the saccular process thick and stout in H. hainana ; vesica with a short and thick process in H. pseudobutleri , vesica with a long and slender process in H. hainana .

Description. Male. Length of forewing 24 mm.

Head: antennae filiform, brownish; labial palpus brownish.

Thorax: brown, tegulae brown, abdomen dorsally covered by short brownish hair; forewing apex pointed and slightly falcate, termen convex from vein M 2 to vein Cu 2. Forewing ground color brown, scattered with numerous black scales; antemedial line black and irregular, extending from costa to cell; medial line black and obscure, extending from costa to vein R 5 and followed by a ring-like reniform stigma at lower portion of discoidal cell; orbicular stigma black, dot-like; postmedial line black and obscure, extending from costa to vein R 4 and nearly parallel to the dorsum; submarginal line reddish brown, thick and straight, extending from apex to median of dorsum; an obscure whitish line along the inner edge of the submarginal line. Hindwing ground color as forewing at lower two thirds, whitish at costal and subcostal area; medial line reddish brown and thick, extending from subcostal area to vein 3A, and inwardly flanked by a vestigial whitish line.

Female. Length of forewing 25 mm. Compared with the male adult, the color of the wing is darker, the submarginal line of forewing and medial line of hindwing with a obvious whitish grey edge and the black dots covered are more obvious and more dense.

Male genitalia. Uncus long and slender, curved towards basal part. Tegumen short and broad, triangular. Saccus broad and short. Transtilla n-shaped, consisting of two inwardly curved lobes. Juxta H-shaped, broad, consisting of two inwardly curved lobes. Valvae long and slender, gradually narrowing from base to apex. Costa strongly sclerotized. Sacculus strongly sclerotized, left saccular process short, thumb-like, curved inwards; right saccular process long, strongly curved at median region. Aedeagus slender, curved inwardly towards apical part. Vesica with some flakes and a sclerotized and hook-like process.

Female genitalia. Papillae anales slender and covered by short hairs; apophyses posteriores longer and more slender than apophyses anteriores; two small bunches of short hairs present on both sides of the ostium bursae; ductus bursae long, bulged at anterior part and strongly sclerotized; ductus seminalis spiral; corpus bursae pyriform and membranous, without ornamentation.

Distribution. China: Guangdong.

Etymology. The specific name pseudobutleri is derived from the other specific name butleri (Leech) due to the resemblance of the present new species in external characters to the species H. butleri .
