Figs 28–33 Type material. Holotype : male, PHILIPPINES : Luzon, Laguna Prov., Mt. Makiling, December 1993 (UBC-SEM AR00175, FSCA ). Paratypes : 1 female , same data as holotype (UBC-SEM AR00176, FSCA ); 1 male , same data as holotype ( FSCA ); 1 male , PHILIPPINES : Luzon, Laguna Prov., Mt. Makiling, March 1993 ( FSCA ). Etymology. The specific epithet is a patronym in honor of Dr. G. B. Edwards, who collected and provided specimens of the species for this study. Diagnosis. Male of this species can be distinguished from Lagnus longimanus L. Koch (see Wanless 1988 ) by the absence of a crescent-like light colored marking at the posterior end of the carapace ( Fig. 28 ), the much shorter palpal femur and patella, the longer retrolateral tibial apophysis of the male palp ( Fig. 30 ). Female of this species differs from L. monteithorum Patoleta, 2008 by the shape of the epigynal window ( Fig. 32 ) and the oval spermatheca ( Fig. 33 ). FIGURES 28–33. Lagnus edwardsi sp. nov. 28 male holotype, dorsal view; 29 female paratype, dorsal view; 30 male left palp, ventral view; 31 male left chelicera, back view; 32 epigynum, ventral view; 33 cleared epigynum, dorsal view. Scale bars: 28–29, 2.0 mm; 30–33, 0.2 mm. Description. Male ( holotype , UBC-SEM AR00175). Carapace length 3.2; abdomen length 3.9. Chelicera ( Fig. 31 ): red brown; with two promarginal teeth and one retromarginal tooth of 5–6 cusps; back surface with a big depression; fang with a few denticles at upper surface. Palp ( Fig. 30 ): femur and patella yellow brown, tibia and cymbium sandy yellow. Embolus long and coiled for about half a circle; retrolateral sperm duct loop wide occupying more than three quarters of bulb width; cymbium with one prolateral and one relateral macrosetae; retrolateral tibial apophysis long finger-like, reaching the proximal end of embolic disc. First pair of legs slender, with nine pairs of ventral macrosetae on tibia; with six ventral macrosetae on the prolateral side and eight ventral macrosetae on the retrolateral side of metatarsus. Measurements of legs: I 13.9, II 10.3, III 10.8, IV 11.6. Color in alcohol ( Fig. 28 ): carapace dark yellow brown with sandy yellow lateral margins and a middle stripe behind fovea; abdomen gray brown with a light yellow medial marking; venter gray brown; legs sandy yellow to dark yellow brown. Female ( paratype , UBC-SEM AR00176). Carapace length 2.7 (variation 2.9–3.2, n=3); abdomen length 3.9. Teeth pattern on chelicera similar to that of male. Tibia of first leg with eight pairs of ventral macrosetae; metatarsus with six pairs of ventral macrosetae. Measurements of legs: I 6.7, II 5.8, III 6.8, IV 7.4. Epigynum ( Fig. 32 ): window wide with opening to copulatory duct close to its posterior end; median septum relatively wide. Vulva ( Fig. 33 ): copulatory duct short with accessory gland; spermatheca oval. Color in alcohol ( Fig. 29 ): similar to that of male. Natural history. Specimens were found from large buttressed trees on the sides of the large buttresses, where they were observed to move rapidly on the flat surface.
