Phylocentropus tohoku Arefina-Armitage & Armitage 2011, sp. n.

Phylocentropus tohoku sp. n. (Figures 1-4) Diagnosis. The male of Phylocentropus tohoku most closely resembles Ph. narumonae in the shape of the preanal appendage and the inferior appendage in lateral view. It is distinguished by the shape of segment Xin dorsal view, having a roundly bilobed dorsal portion and a slender, acuminate ventral portion, which extends beyond the dorsal portion. Adult. Length of male forewing 6.8 mm. Color of body and wings light brown. Forewings with venation complete; hind wings with forks I, II, III, and V. Male genitalia. Sternite IX 2 times as long as wide; in lateral view, anterior portion triangular with acute apex; posterior margin broadly rounded. Segment X long, nearly rectangular in lateral view, with distal marginhaving shallow concavity; in dorsalview, broadlyrounded and bilobed, with ventralprocesses slender, acuminate, extending slightly beyonddorsal portion. Preanal appendage large, dorsal and ventral margins parallel, apexbroadly rounded. Intermediate appendage large, banana-like in lateralview. Inferior appendage mitten-like in lateral view; inner surface of dorsal lobe bearing elongate projection directed posterad in lateral view, same projection with complex shape in ventral view. Phallotheca and endotheca almost equal in length; endotheca armed with long, unpaired spiniform process. Female and immature stages. Unknown. Holotype male. Vietnam, Ha Tinh, Huong Son, 200 m, 18 o 21’N, 105 o 15’E, Malaise trap, 15 May 1998, J. Carpenter, K. Long, D. Grimaldi, L. Herman, D. Silva. Distribution. Known only from the type locality in Ha Tinh Province (Vietnam). Etymology. This species is named to honor and remember the many lives lost in the Tohoku District of the Japanese island of Honshu during the March, 2011 earthquake and tsunami. The word “Tohoku” refers to the northeast (to = east; hoku = north) district of Honshu. The Japanese meteorological agency refers to this event as the Tohoku Earthquake.Published as part of Arefina-Armitage, I. T. & Armitage, B.

Phylocentropus anas Arefina-Armitage & Armitage 2011, sp. n.

Phylocentropus anas sp. n. (Figures 10-13) Diagnosis. The male genitalia of this species closely resemble those of Ph. vietnamellus primarily in the shape of segment Xin dorsal view, and somewhat in the shape of the inferior appendage in lateral view. However, Ph. anas is distinguished from Ph. vietnamellus by segment Xbifurcate for half of the entire segment length; by the triangular preanal appendage with broad base; and, by the shape of the inferior appendage in ventral view. Adult. Length of male forewing 7.0 mm. Main color of body and wings yellowish-brown. Forewings with venation complete; hind wings with forks I, II, III, and V. Figures 5-9. Phylocentropus ngoclinh sp. n., male genitalia. 5) Lateral view. 6) Dorsal view. 7) Ventral view. 8) Phallic apparatus, lateral view. 9) Distal portion of phallic apparatus, dorsal view. Male genitalia. Sternite IX 2.5 times as long as wide; in lateral view, anterior portion tapering to blunt apex, posterior portion broadly quadrate with rounded corners. Segment X long, duck head-shaped in lateral view, bifurcatein dorsal view. Preanal appendage large, elongate, broad basally, gradually tapering apically, with rounded apex in lateral view. Intermediate appendage absent. Inferior appendage leaf-like in lateral view; inner surface with dark bump, located dorsobasally; and, with undulate row of setae going across appendage. Phallic apparatus long and slender; endotheca very narrow, tapering to acute apex, slightly bent ventrocaudad. Female and immature stages. Unknown. Holotype male. Vietnam, Ha Tinh, Huong Son, 1240 m, 18 o 21’N, 105 o 15’E, Malaise trap, 14 May 1998, J. Carpenter, K. Long, D. Grimaldi, L. Herman, D. Silva. Distribution. Known only from the type locality in Ha Tinh Province (Vietnam). Etymology. This species is named for segment X, duck head-shaped, in lateral view (“anas” is Latin for duck). Figures 10-13.

New species of caddisflies (Insecta: Trichoptera) from emergence traps at streams in central Palawan, Philippines

New species of Trichoptera were identified in samples collected from emergence traps along two streams (Cabayugan River and Panaguman River) at Puerto Princesa Subterranean River National Park, Palawan, Philippines in 2000–2001. The species are described as: Orthotrichia ligula sp. n., Chrysotrichia minutula sp. n., Chimarra ligula sp. n., Pahamunaya panagumani sp. n., Tinodes sanctipauli sp. n., Ecnomus cabayugani sp. n., E. tagbanwae sp. n., Hyalopsyche palawanensis sp. n., Pseudoneureclipsis extensata sp. n., Helicopsyche forcipula sp. n., Anisocentropus palawanensis sp. n., Leptocerus palaservius sp. n., Leptocerus membranellus sp. n., Tagalopsyche brunneoides sp. n. and Oecetis ausani sp. n. All male genitalia are illustrated, supplemented by the female genitalia for some species. The illustrations of the male genitalia of an unnamed species of Triplectides Kolenati, 1859 (Leptoceridae) are provided. The relationship of the new species to congeners is briefly discussed. The subfamilies Hyalopsychinae (Dipseudopsidae), represented by two species, and Pseudoneureclipsinae (Dipseudopsidae), represented by one species, are recorded from Palawan for the first time. The genus Pahamunyana Schmid, 1958 (Poycentropodidae) is a new country record
