  • Genus Pacificulla Park, gen. nov. Type species: Pacificulla flaviagera Park, sp. nov. Description. Head: Usually dark brown or orange white. Antenna usually fasciculate- ciliated with whitish hairs on flagellum, cilia sometimes absent. Labial palpus sexually dimorphic: male with second segment normally thickened, extremely long, with acute apex, third segment reduced or absent (Fig. 21); female with second and third segments slender, third as long as second or shorter than second. Thorax: usually dark brown or orange white dorsally. Forewing and hindwing with similar color pattern and markings, dark brown or purplish brown fascia in basal and posterior parts, or a large orange or dark orange patch in middle part of wing; venation with R 2 and R 3 + 4 stalked or sometimes approximated, R 5 and M 2 absent. Hindwing usually broader than forewing; venation with M 2 absent. Abdomen: usually orange, often blackish on first and second segments, with blackish anal tuft, sometimes fuscous dorsally throughout, with spinous zones on tergites. Male genitalia: uncus usually elongate; gnathos absent; tegumen broad; valva elongate, densely setose, sometimes with strong bristles on surface; aedeagus usually broad at base, then narrower towards apex; cornuti consist of a sheaf of bristles, occupying 1 / 3 length of aedeagus or shorter. Diagnosis. Pacificulla gen. nov. is related to Crocanthes Meyrick, sharing the apomorphic characters of long antennae and the absence of the gnathos in the male genitalia. The genus is defined by a combination of morphological characters as follows: 1) Wing color and pattern similar on upper surface of fore- and hindwings, with large orange or dark orange patch in the middle of wings; venation with R 2 and R 3 + 4 stalked or sometimes approximated; R 5 and M 2 absent; 2) labial palpi sexually dimorphic: male usually with the second segment normally thickened, long, with acute apex, and the third segment absent or reduced; third segment unmodified in female; and 3) male genitalia with elongate valva bearing a dense patch of strong bristles on the cucullus and the aedeagus with a row or sheaf of needle-like cornuti. Distribution. New Guinea (Papua New Guinea and Papua of Indonesia) Etymology. The genus name is derived from the pacific with suffix, ullus.
