Figs 13 –17, 49

Type material. Holotype male, CHINA: Jiangsu Province, Nanjing City (32.0° N, 118.5 ° E), lacking detailed collecting data. ( IZCAS)

Etymology. The species name is a compound word of the Latin magnus, -a, -um and the Latin arcuatus, meaning “large” and “arcuated” respectively, and refering to the shape of the embolus; adjective.

Diagnosis. This species is similar to Draconarius rufulus (Wang, Yin, Peng & Xie 1990)  in having the distal embolus abruptly becoming narrow and lacking the patellar apophysis, but can be distinguished by the absence of a median apophysis and the presence of an apophysis on the tegular sclerite and the extraordinarily strong embolus.

Description. Holotype male. Total length 7.8, prosoma 4.3 long, 2.9 wide; opisthosoma (decayed) 3.5 long, 2.3 wide. Eye measurements: AME 0.15; ALE 0.25; PME 0.18; PLE 0.18; AME –AME 0.08; AME – ALE 0.05; PME –PME 0.10; PME –PLE 0.20; clypeus 0.06. Chelicerae with 3 promarginal and 2 retromarginal teeth (Fig. 13). Leg formula: IV, I, II, III; measurements of legs: I: 11.2 (3.1, 3.8, 2.7, 1.6); II: 9.7 (2.7, 3.2, 2.4, 1.4); III: 9.0 (2.5, 2.9, 2.4, 1.2); IV: 12.2 (3.3, 3.9, 3.5, 1.5).

Patellar apophysis absent; RTA shorter than tibia; lateral tibial apophysis distinct and widely separated from RTA; cymbial furrow about one third of cymbium length; conductor strongly curved basally, strongly modified into a groove holding the distal end of embolus, and with a process on the ventral margin of conductor; median apophysis absent; embolus strong at the basal two thirds and abruptly becoming slender at the distal one third, arising at approximately 6 –o’clock –position (Figs 14–16).

Female. Unknown.

Distribution. China (Jiangsu) ( Fig. 49View FIGURE 49).
