Material examined. 3 males, 3 females, Philippines: Luzon, Los Baños, Laguna, on Pterocarpus indicus Willd.  , 27-vi-2014 (C. C. Lucañas UPLBMNH EMB-00011 ♂); on Cassia fistula L., 25- vi-2014 (C. C. Lucañas UPLBMNH EMB-00012 ♂ - 13♀); on Araucaria heterophylla (Salisb.) Franco  , 25-vi-2014 (C. C. Lucañas UPLBMNH EMB-00014 ♀); on Vitex parviflora Juss.  , 25-vi-2014 (C. C. Lucañas UPLBMNH EMB-00015 ♂ - 16♀)

Distribution. Cosmopolitan.

Diagnosis. Distinguished from males of other species by the sickle-shaped LPPT.

Description. Size (mm): ♂: BL: 7.7 ± 0.26; HL× HW: 1.2 ± 0.12 × 0.9 ± 0.06; OR: 0.40 ± 0.01; FW: 5.6 ± 0.46; HW: 4.3 ± 0.23. ♀: BL: 8.9 ± 0.5; HL × HW: 1.3 ± 0.06 × 1.1 ± 0.17.

Alate male ( Fig. 4AView FIGURE 4) generally dark brown-black. Head dark brown. Eyes medium-sized, slightly protruding beyond head capsule. Antennae filiform, covered with setae. Submentum trapezoidal, anterior margin convex, edges slightly rounded ( Fig. 4CView FIGURE 4). Terminalia ( Figure 4View FIGURE 4 E-F): LCB projecting as a narrow rounded lobe and surrounding base of LC. 10LP tapering, basally constricted, medially broad. 10RP narrow, elongate, distally truncate. H broad basally, narrowing to a slightly recurved HP. LPPT sickle-shaped.

Female ( Fig. 4BView FIGURE 4) generally black. Hind basitarsus with single papilla. Sternite 8 with two oblique caudally converging lines ( Fig. 4GView FIGURE 4). Sternite 9 with small unpigmented inverted triangle ( Fig. 4GView FIGURE 4).

Remarks: Like O. humbertiana  , O. saundersii  has been anthropogenically introduced to numerous countries ( Ross 1955). Ross (1984) stated that O. saundersii  is the most widespread webspinner and may be found in all warm regions, especially near urban areas.
