Material examined. Holotype. male, “KH56” / “ Philippines | Leyte Is. Mt. Balocaue | 2011”, genitalia preparation No. KH56 ( CKH, will be deposited in a public collection later) . Paratypes. 1 male, 5. VI .2002, Mt. Halcon , Mindoro, The Philippines, leg. native collector, genitalia preparation No. KH 57 ( CKH) ; 1 male, VI . 2000, Mt. Halcon , N Mindoro, The Philippines, leg. N. Mohagan, genitalia preparation No. MfNHSY023 ( MfN) .

Diagnosis. Docleomorpha zeta sp. nov. can be distinguished from D. epsilon sp. nov. superficially by the shorter, somewhat broader and less obliquely placed yellow band on forewing. In male genitalia, it can be distinguished by the shorter uncus with medially concave lateral margins (lateral margins straight in D. epsilon sp. nov.) and the ζ-shaped distal process of sacculus (ε-shaped in D. epsilon sp. nov.). The comparison with D. boholica is provided above in the diagnosis of that species.

Description. External morphology of adults. Length of forewing 12–13.5 mm in male. Antennae black, bipectinate. Head, thorax and abdomen black dorsally and yellow ventrally. Abdomen ringed with yellow between segments. Forewing ground color black with a rodlike yellow stripe extending from costa to vein CuP. Hindwing ground color black, the yellow patterns consisted of a pale yellow stripe stretching along costal area and a yellow club-like stripe extending from wing base to submarginal zone medially. Male genitalia. Uncus nearly rectangular, with its distal and lateral margins slightly concave, bearing setae along lateral and distal edges. Scaphium moderately sclerotised, band-like. Tegumen nearly trapezoid, about 1.5 × the width of the uncus. Posterior bilateral projection blade-like with the bases of the projections connected medially by a band-like sclerite. Vinculum moderately broad, nearly the same width of the tegumenal lobe. Juxta M-shaped. Saccus distally rounded and broad U-shaped. Valva broad (ca. 3.5 × uncus length) and short (ca. 2 × uncus length), costa stripe-like, simple; valvula membranous and fan-shaped, covered sparsely with setae; sacculus band-like, elongated (ca. 2 × uncus length), with the distal one third of the outer margin covered with numerous spike-like spines and the distal section formed a ζ-shaped process. Lamella centralis long triangular, extended from the base of valva to the distal section of sacculus. Phallus elongated, simple and cylindrical with coecum well-developed.

Female unknown.

Distribution. The Philippines (Mindoro and Leyte Islands).

Etymology. The specific epithet zeta is derived from the lower-case Greek letter “ζ”, referring to the shape of the distal section of sacculus. It is a noun in apposition.
