Diagnosis. This species is somewhat similar to H. indicus and H. hauserianus in having elytra with only two lateral intervals punctate and with microsculpture on disc in baso-medial portion consisting of narrow transverse meshes, but distinctly differs from two these species in having more prominent humeral denticle, visible dorsally, and in shape of pronotum with rather deep lateral depressions, separated from somewhat deep and narrow basal foveae by convex areas. Besides, one or two lateral intervals of elytra are very finely pubescent. Metafemur has three setigerous pores along posterior margin. The median lobe of aedeagus ( Figs 82–83 View FIGURES 82 – 85 ) has two separate spines in the internal sac. Body length 9.2–11.2 mm.

Distribution. China: mainly in the central and southern parts. In China, the species was previously known from Zhejiang, Hubei, Hunan, Sichuan, Guizhou, Guangdong, Guangxi, Yunnan and Fujian ( Kataev et al. 2003; Liang & Liu 2007). We examined additionally specimens from Taiwan. The records by Hua (2002) from Heilongjiang, Jilin, Nei Mongol, Hebei, Henan, Shaanxi, Gansu, Anhui, Jiangsu, Jiangxi, Hunan and Xizang seem to be based on misidentifications.

The species is also distributed in Vietnam ( Kataev 1997) and Laos. The species is reported from Laos and the Chinese province Taiwan for the first time.

Remarks. As stated by Kataev (1997), H. singularis is very similar and apparently closely related to two allopatric Japanese species: H. azumai Habu from Ryukyu Islands and H. aogashimensis (Habu) from Aogashima Island. All three species seem to form a monophyletic subgroup based on unique combination of characters: shape of pronotum with distinct obtuse basal angles, blunt at apex, microsculpture on elytral disc in baso-medial portion consisting of clearly transverse meshes, presence of three (rarely four) setigerous pores along posterior margin of metafemur and aedeagus with two large spines in internal sac. Harpalus azumai is distinguished from H. singularis by elytra punctate on all intervals and pronotum with flatter latero-basal areas (its median lobe is illustrated in Figs. 84–85 View FIGURES 82 – 85 ). Harpalus aogashimensis , which is known to us only from Habu’s descriptions ( Habu 1957, 1968, 1973), is recognizable by pronotum with impunctate baso-medial area; like H. singularis , its elytra are impunctate on disc. The records of H. aogashimensis from China (Guangdong and Sichuan) ( Hua 2002) are surely based on misidentification.

Harpalus chengjiangensis was described from two specimens (male and female) collected in Chengjiang, Beibei, Chongqing, China. According to the original description ( Huang 1993), this species is "close to H. babai , but differs in dorsal surface of head glabrous, interval 7 without additional pores, hind femur with 3 setae near hind margin, sternite 5 glabrous". We had no opportunity to study the type specimens, but several males and females examined by us from Fujian (see material above), which were determined by Huang Tongling as H. chengjiangensis , belong to H. singularis . Because all the distinctive characters mentioned in the original description of H. chengjiangensis fit those of H. singularis , we treat the former name as a junior synonym of the latter.
