DIAGNOSIS. The new species is distinguishable by having a wide leaf-shaped cucullus;

glandiductor inflated basally and heavily narrowed distally, bearing a small, rounded lobe at the apex; sternal part of genitalia with two pairs of processes – ventral processes of juxta bearing strong thorns at the apex; and lobe-like, setaceous lateral processes in the male genitalia. It is determined by finger-like apices in the papillae anales; honeycomb-patterned antevaginal plate with triangular centered sclerotization covering the ostium and antrum ventrally; and arched, triangular signum with a rounded apex in the female genitalia.

DESCRIPTION. Adult ( Figs 1, 2 ). Forewing length 3.0– 3.2 mm. Head pale sandy, uni-

colorous, or with scattered scales dark on top. Antennal scapus pale sandy with brownish or blackish bands, flagellum with alternating dark grey and blackish segments. Basal segment of labial palpus pale sandy or brownish; second segment longer than third, widened distally,

pale sandy with disseminated brownish scales or brownish with white distally; third segment white with two black bands near base and beyond the middle. Forewings sandy with intensive darkening in male and pale sandy with scattered brownish scales in female; proximal half of type; 3 – wing venation; 4 – 2nd sternite, female; 5 – 1st and 2nd tergites, male. Scale bar 0.5

mm.

wing with two indistinct blackish spots along anal vein, distal part of wing with a greybordered black spot at middle and concolorous blackish-bordered or grey-bordered spot near tornus, apical part of wing with row of brown dots along costal and outer margins; fringe sandy along the apex and outer margin, and brownish or grey along dorsal margin ( Figs 1, 2 ).

Hindwing and fringe grey or brownish. Forewing with Sc to costa at about 2/5 of wing length; R 1 – R 5 to costa, each separate at base; M 1 to dorsal margin below apex, separate at base; M 2 probably absent; M 3 separate; CuA 1 and CuA 2 separate basally, to dorsal margin;

1A + 2A forked at base. Hindwing with Sc to costa beyond the middle; Rs to apex; M 1 to termen, M 2 probably absent, M 3 separate at base; CuA 1 and CuA 2 from Cu stem separately,

2A short, to dorsal margin at 1/4 of wing length ( Fig. 3 ).

Forefemur and foretibia sandy with intensive brownish darkening, tarsomeres dark brown with white spot distally; midfemur grey, midtibia dark brown, with raised scales in proximal part and whitish collars at middle and in distal part; hindfemur grey with brown darkening on outer side, hindtibia sandy with brown darkening on outer side and brush of hair-like sandy scales on upper and lower margins in proximal part.

Second abdominal sternite with well-developed apodemes and sinuous venulae ( Fig. 4 ).

Invagination between the first and second abdominal tergites filled with a dense bundle of modified scales of unknown function ( Fig. 5 ).

Male genitalia ( Figs 6–9 ). Tegumen a small arched plate, emarginate posteriorly, anterior margin produced, triangular ( Fig. 6 ). Cucullus with wide base, broadened beyond middle, its maximal width almost the same as half of length; glandiductor mediad cucullus, strongly inflated basally and narrowed towards apex, its base almost 9 times wider than distal part, its apex with rounded plate ( Fig. 9 ). Vinculum, juxta and probably both sacculi fused into single ventral sclerite without distinct sutures, saccus absent. Distal part of ventral sclerite with a pair of processes, probably homologous to processes of juxta based on their position, bearing small strong thorns at apex and with a rounded notch between. Ventral sclerite with another pair of lobe-like setaceous processes laterally, according to their position homologous to processes of anellus. Aedeagus straight; apex truncate; inflated beyond middle, with ejaculatory ductus entering dorsally near base; fixed in sternal part of genitalia; enveloped latero-ventrally by both pairs of processes of ventral sclerite ( Figs 7, 8 ).

Female genitalia ( Figs 10–14 ). Ovipositor short, papillae anales sclerotized, with elongated digital apices ( Fig. 13 ). Apophyses posteriores 2 times as long as free part of apophyses anteriores, the latter extending along lateral sides of 8th segment almost to its posterior margin. Sternal part of 8th segment separated by splits into medial with rounded posterior margin and lateral parts diverging anteriorly ( Fig. 12 ). Ostium at level of anterior margin of 8th segment and at level of bottom of cut in honeycomb-patterned antevaginal plate covering ostium and antrum ventrally; antevaginal plate with triangular centered sclerite ( Figs 11, 12 ). Antrum sclerotized and goblet-shaped; ductus bursae membranous,

mainly tube-like, slightly widened towards the corpus bursae; corpus bursae oval,

membranous; signum arched, triangular with rounded apex, located at opening of ductus bursae ( Figs 10, 14 ).

DISTRIBUTION. East Malaysia (Sabah).

ETYMOLOGY. The species name is derived from the Latin “ sulphuratus ” meaning sul-

furic (=sulphureous), because of the yellowish, sulfur-coloured forewing.
