MATERIAL
Holotype: ♂ (specimen identifier coll.mfn-berlin.de_u_810de4, DNA voucher MFNLEP-PYRALPHIL01-E03, genitalia on slide TL916♂; BOLD sample ID PYPHI038-21, Genbank Accession Number PP196730). PHILIPPINES: Luzon, Zambales, Zambales Mountains, Pili, 150 m, 05-07.11.1998 (W. Mey, W. Speidel). Deposited in MfN.
Paratype: 3 ♂ (specimen identifiers coll.mfn-berlin.de_u_2c5838, ace978, 8e5a61), 2 ♀ (specimen identifiers coll.mfn-berlin.de_u_d9a2c0, 62cddb) (detailed information in Table S1; https://doi.org/10.5061/ dryad.b8gtht7mh).
Other specimens: 32 unsexed (detailed information in Table S1; https://doi.org/10.5061/dryad.b8gtht7mh).
DIAGNOSIS
This peculiar looking Culladia species is unambiguously separated from other Culladia species by the larger and broader forewing mixed with brown and white scales and the brown marginal lunules, while the zigzag postmedian brown line found in other species is absent. In male genitalia (Fig. 114), the large tegumen arms, the setose costal projection of the valva, as well as the long cornutus on vesica unambiguously separate this species from other Culladia species. In female genitalia (Fig. 171), the non-coalesced papillae anales, the very long ductus bursae, as well as the presence of an appendix bursae on the corpus bursae unambiguously separate this species from other Crambinae species.
HABITUS
Forewing length 8 mm (n = 1); greyish brown, scattered with cream scales. Antemedian line cream, forming a jag pointing outwards in cell. Median area lighter, with one costal, one cubital, and one dorsal dark brown patch. Postmedian line broken, cream, starting at 4/5 of costa, well marked near costa, broadly arched outwards down to CuA1, then slightly arched outwards in dorsal area, meeting the dorsum near tornus. Subterminal area broadly marked with white suffusion, more pronounced towards margin. Margin with seven dark quadriangular spots. Fringe basally cream, distally bronze.
MALE GENITALIA (FIG. 114)
Uncus elongate, slender, densely setose; apex with small tooth pointing downwards. Gnathos projection about as long as uncus, apex with small tooth pointing downwards. Tegumen arm large, covered with minute points, tegumen roof ca 4/5 of tegumen arm length. Valva elongate, slender, slightly curved upwards on distal 1/4, apex rounded. Costal process slightly S-shaped, covered with setae, tip pointing upwards. Juxta short, rounded, deeply indented. Phallus stout, apically narrowed, apex forming two narrow, spatulate, weakly sclerotized projections. One straight, large, elongate cornutus of 660 μm.
FEMALE GENITALIA (FIG. 171)
Papillae anales not connected dorsally and ventrally, slightly concave. Antrum membranous. Ductus bursae covered with minute spicules, straight, narrow in basal half, broadly incurved on distal half, slightly broader, conspicuously bent before corpus opening. Corpus bursae membranous, globular, with a small globular appendix bursae. Signum absent.
DISTRIBUTION
PHILIPPINES: Luzon (Mountain Province, Ifugao, Zambales). Collected at altitudes between 150 and 2100 m.
DNA BARCODING
An intraspecific divergence of 2.9 % is observed between specimens MFNLEP-PYRALPHIL01-F03, MFNLEP-PYRALPHIL01-C06, and MFNLEP-PYRALPHIL01-B10 all from Zambales, Luzon.
ETYMOLOGY
From the Greek pseudes, false, and the genus Scoparia Haworth, referring to the resemblance in habitus and female genitalia with specimens of Scoparia.
REMARKS
This species is tentatively placed in Culladia here. According to Graziano Bassi (pers. comm.), the “male genitalia [is] similar to Pediasia, but the bilobed apex of phallus and ductus ejaculatorius branching off close to antrum bursae are diagnostic. It is somewhat similar to C. dentilinealis Hmps and somewhat “heretical” with respect to typical Culladia in female genitalia, but surely close to it, as male genitalia show”.
