Material examined.

1 female: Philippines: Polillo Island (Quezon Province): Cave 3-4, Sitio Puting Bato, Barangay Aluyon, Burdeos, 01.iii.2013 (CC Lucañas, UPLBMNH BLA-00533).

Description.

Size (mm): TL: 13.50; Pn: 3.00 × 4.00; Tg: 10.00.

Male: Unknown.

Female: Vertex of head slightly exposed. Ocelli minute. Pronotum anteriorly ellipsoid, wider than long, with brown central maculae, anterior and lateral areas hyaline. Fore femur type A2. Mid femora armed with row of spines on outer aspect. Hind femora missing from specimen. All tarsomeres with pulvilli, 1-3 spined. Tarsal claws symmetrical with minute dentations. Arolium present. Tegmina well-developed.

Remarks.

Accidentals. Since only one female specimen was collected and troglomorphic characters are absent, it can be said that its presence in the cave was accidental.

Roth (1990) described Shelfordina philippensis from Camarines Sur, but later transferred it to the genus Margattea ( Roth 1996). Both genera are morphologically similar except for the armature of the fore femora, i.e., type A for Shelfordina and B for Margattea , and the presence of tergal gland on the eighth abdominal segment in males of Margattea .
