Diagnosis.

Adults of this species (Fig. 19) can be distinguished from those of all other species in the region by the following combination of character states: body length 8.3-8.4 mm; dorsal surface dark brown to black, without metallic reflection, at least femora and outer antennomeres dark (piceous to black); elytral microscuplture com prised of distinctly transverse meshes in both males and females (more transverse and less deeply impressed in males than in females); pronotum (Fig. 19a) only slightly narrower anteriorly than basally, anterior margin almost as wide as posterior margin, lateral margins more or less evenly rounded from apical to basal angle, anterior angles slightly projected anteriorly beyond anterior margin, posterior angles sharp, not rounded, outer basal impressions sharply delimited laterally by narrow, slightly oblique raised (but not carinate) areas, pronotal base very coarsely punctate; elytra with parascutellar pore puncture absent; medial protibial spurs simple; metatibia of male with brush-like setae medially in the apical half; tarsomere 5 of hind tarsi with two or (in a few specimens) three pairs of setae ventrally (Fig. 6b); last abdominal sternite of male with one pair (Fig. 5e) and female with two pairs (Fig. 5c) of setiferous punctures near hind margin.

Habitat distribution.

Specimens of this species were collected in daytime from under stones on the open bank of a small stream at an elevation of 1740 m and at night on wet stones along a roadside at 1515 m elevation. The only other Amara species members of which were found syntopic with those of Amara simplicidens was Amara lucidissima , with adults of both species found together at the 1740 m site.

Geographical distribution within the Gaoligong Shan.

Fig. 19d. We examined a total of 2 specimens (1 male and 1 female) from the following localities: Tengchong County: Datang Village (Maluchong, 25.58194°, 98.67583°, 1740 m, 24 October 2003, H.B. Liang collector [1 male; CAS]); Longchuan Jiang (at Xiangyang Bridge, 25.21056°, 98.58028°, 1515 m, 23 October 2003, H.B. Liang & X.C. Shi collectors [1 female; IOZ]).

This species was recorded only from the western slope of the southern part of the study area (Core Area 6).

Overall geographical distribution.

Fig. 27. This species has been recorded from China (Fujian, Heilongjiang, Henan, Hubei, Jiangsu, Jiangxi, Sichuan,Yunnan, and Zhejian Provinces), Japan, North Korea, and Russia (Khabarovsk and Primorsky Kraya, Sakhalinskaya Oblast, and the Kuril Islands). Its occurrence in the study area represents the western limit of its known geographical range.
