Type material. Holotype ♂, CHINA, Yunnan Province, Gongshan County, Dulongjiang Township: Longyuan Village, 28.00917°N, 98.32217°E, 1676 m, 31.X – 3.XI.2004, Guo Tang leg. (Tang-04-06). Paratypes: 1♂ 3♀, same data as holotype (Tang-04-06); 1♂, Xianjiudang Village, 27.93914°N, 98.33214°E, 1634 m, 4–5.XI.2004, Guo Tang leg. (Tang-04-07); 1♀, Mokewang bridge, 27.83827°N, 98.32103°E, 1455 m, 6–7.XI.2004, Guo Tang leg. (Tang-04-08); 1♂ 1♀, Kongdang Village, 27.87961°N, 98.33878°E, 1527 m, 25.X.2004, Guo Tang leg. (Tang-04- 04); 1♂ 2♀, 2.3–3.3 air km south of Longyuan Village along Dulongjiang River, 28.00532°N, 98.32145°E, 1685 m to 28.01347°N, 98.32117°E, 1720 m, 2.XI.2004, D. H. Kavanaugh leg. (DHK-2004-068).
Etymology. The specific epithet is the combination of the Latin “ floris ” (flower, blossom) and “ formis ” (form), referring to the flower-like scape; adjective.
Diagnosis. The new species resembles A. zhaoi Zhang & Zhang, 2002 (Zhang & Zhang 2002, fig. 1), but can be distinguished by: 1) anterior rim of tegular rounded in ventral view in A. floriformis n. sp. (Fig. 4B) vs. waved in A. zhaoi (Zhang & Zhang 2002: fig. 1D); 2) median apophysis uniramous in prolateral view in A. floriformis n. sp. (Fig. 4A) vs. with two rami in A. zhaoi (Zhang & Zhang 2002: fig. 1E); 3) distal portion of terminal apophysis sligntly curved in prolateral view in A. floriformis n. sp. (Fig. 4A) vs. hook-shaped in A. zhaoi (Zhang & Zhang 2002: fig. 1E); 4) scape straight, slightly wider than long, almost flower-like in A. floriformis n. sp. (Fig. 4G) vs. Sshaped, much longer than wide in A. zhaoi (Zhang & Zhang 2002: fig. 1B); 5) copulatory openings located laterally in A. floriformis n. sp. (Fig. 4G) vs. located posteriorly in A. zhaoi (Zhang & Zhang 2002: fig. 1C).
