Figs 10 , 18K, L Type material. Holotype ♀ (IZCAS-Ar43109), China: Yunnan, Xishuangbanna, Mengla County, Menglun Township, Menglun Nature Reserve, Lueshilin Forest Park, limestone seasonal rainforest ( 21°54.56'N , 101°16.86'E , ca 610 m), 29.XI.2009, G. Tang leg. Paratype : 1♀ (IZCAS-Ar43110), Lueshilin Forest Park ( 21°54.71'N , 101°16.90'E , ca 660 m), 13.XI.2009, G. Tang leg. Etymology. The specific name comes from the Latin word "cucullatus" , meaning "hooded" , referring to the hood on the ventral surface of the epigyne. Diagnosis. The new species resembles A. arcuatus sp. nov. in appearance, but it can be distinguished from the latter by the following: 1) epigyne about 2 times wider than long vs about 1.65 times wider than long (Fig. 1A, B ); 2) copulatory openings situated on posterior surface vs ventral surface (Fig. 1A, B ); 3) spermathecae separated vs touching each other (Fig. 1B ); and 4) abdomen with sparse, long setae vs lacking sparse, long setae (Fig. 1E ). Description. Female (holotype, Fig. 10 , paratype Ar43110, Fig. 18K, L ). Total length 4.80. Carapace 1.90 long, 1.50 wide. Abdomen 3.30 long, 2.90 wide. Clypeus 0.13 high.

Carapace pear-shaped, yellow, cervical groove distinct. Chelicerae yellow, 4 promarginal teeth, 3 retromarginal teeth. Endites almost rectangular, yellow with dark anterior edge, labium triangular, yellow. Sternum cordiform, yellow, with dark setae. Legs yellow without annulus, distal tibia, metatarsus, and tarsus of legs I and II with a cluster of dense macrosetae. Abdomen elliptical, whitish yellow, with sparse dark setae; venter grayish yellow with white scaly spots. Spinnerets grayish yellow. Figure 10.
