AMIOTA FLORMONTANA SP. NOV.

( FIG. 5)

urn:lsid:zoobank.org:act:79CB2837-12F8-47BF-8C5C-6AE8BC451C91

Holotype: SCAU, DIP 111458 , ♂ (19 June 2013).

Type locality: China: Baihualing, Baoshan , Yunnan, 25°17′53″N, 98°48′09″E, elevation 1400 m, Q.S. Gao .

Etymology: A combination of the Latin flo s, meaning flower, and mons, meaning mountain, referring to the name of the type locality.

Diagnosis: This species is similar to A. todai in the male terminalia, but can be differentiated from it by the surstylus with approximately seven small spinules on the outer surface ( Fig. 5B); vertical lobe of gonopod is three-quarters of the basal width ( Fig. 5C). In A. todai , the surstylus is lacking small spinules on the outer surface; vertical lobe of gonopod is as high as wide ( Fig. 5E).

Description

Male terminalia ( Fig. 5A–D): Epandrium nearly separated mid-dorsally, with ~18 setae near posterior and ventral margins per side. Surstylus with no pubescence, with five long prensisetae on distal margin, several thin setae on ventral margin and outer surface. The tenth sternite strongly sclerotized, bilobed, separated mid-dorsally, and a lateral lobe-like process somewhat oblong, narrowly fused to surstyli. Anterior portion of hypandrium entirely thin. Paramere lobe shaped, pointed apically, with one process laterally and with five sensilla medially. Aedeagus separated into a pair of simple rods, each fused to the base of the parameres. Aedeagal apodeme strongly curved.
