9A448783BA13FF8BF158FEAAFDC32403.taxon	discussion	Remarks. According to X ං ൺ & H ൾ (1986), C. hekouensis can be differentiated from C. formosanus by three characters of the winged imagos: color of head capsule yellow brown in C. hekouensis, in contrast to reddish brown in C. formosanus, and C. hekouensis with narrower pronotum and shorter hind tibia than C. formosanus. One diagnostic character of soldiers was mentioned: head capsule elliptical or rounded in C. hekouensis, in contrast to pear-shaped head in C. formosanus. The type specimens of C. hekouensis examined in this study have been preserved for more than 50 years and their coloration likely faded (Fig. 4). We do not consider color as a valid reference because the preserving condition of the specimen may affect the color. The head shapes of the soldiers of C. hekouensis (Fig. 4 c) are overlapping with the shape series of C. formosanus (Figs 3 a – d). In addition, no differences were found between C. hekouensis and C. formosanus in the setae distribution and other characters examined by us. The morphometric measurements of these two species highly overlapped and the differences proposed by X ං ൺ & H ൾ (1986) were not detected in the present study (Table 3 and 4).

9A448783BA13FF8BF158FEAAFDC32403.taxon	discussion	Remarks. L ං et al. (2018) collected termite samples from Feixi County in Hefei, Anhui Province and identified them as C. suzhouensis. The mitochondrial genome of their samples is almost identical to that of C. formosanus, and they further suggested that C. suzhouensis is the junior synonym of C. formosanus. However, no evidence supported the samples they used represented C. suzhouensis. L ං et al. (2018) did not use the type specimens for sequencing, and the samples were not collected from the type locality, Suzhou, Jiangsu, either. The mitochondrial genome provided by L ං et al. (2018) simply proved they misidentified C. formosanus as C. suzhouensis. According to the key provided by X ං ൺ & H ൾ (1986), C. suzhouensis can be differentiated from C. formosanus by five characters of the winged imago: (1) head shape: C. suzhouensis subcircular, C. formosanus rounded; (2) compound eye: C. suzhouensis subcircular, C. formosanus rounded; (3) ocellus: narrower in C. suzhouensis than in C. formosanus; (4) anterior and posterior margin of pronotum: more concave in C. suzhouensis than in C. formosanus; and (5) wings: wider in C. suzhouensis than in C. formosanus. In addition to winged imago, X ං ൺ & H ൾ (1986) mentioned the soldier head capsule of C. suzhouensis was elliptical or rounded and that of C. formosanus was pear-shaped. However, in this study, we found the winged imagos of C. suzhouensis and C. formosanus were similar in the shape of head, compound eye, and pronotum. The measurements of the minimum length of ocellus were not significantly different (Table 4). The head shape of C. suzhouensis soldiers we examined (Fig. 5 c) overlap with the shape series of C. formosanus (Figs 3 e – h). Apart from that, no differences between C. suzhouensis and C. formosanus were found in the setae distribution and other characters examined by us. The morphometric measurements of these two species highly overlapped and the differences proposed by X ං ൺ & H ൾ (1986) are not detected in the present study (Tables 3 – 4).	en	Chen, Guan-Yu, Ke, Yun-Ling, Liang, Wei-Ren, Li, Hou-Feng (2020): Redescription of Formosan subterranean termite, Coptotermes formosanus (Blattodea: Rhinotermitidae), with three new synonyms from China.

9A448783BA1EFF8BF2D9FB28FBAF2103.taxon	discussion	Remarks. According to X ං ൺ & H ൾ (1986), C. shanghaiensis could be differentiated from C. formosanus based on three characters of winged imagos: smaller wing length than that of C. formosanus; narrower pronotum width than that of C. formosanus; and narrower head width than that of C. formosanus. One diagnostic character of soldier caste was mentioned: elliptical or rounded head, in contrast to the pear-shaped head of C. formosanus. No soldier specimen of C. shanghaiensis from the type location was available for this study. The winged imagos of C. shanghaiensis can be distinguished from C. formosanus by the morphometric variation of pronotum (Table 4). Although no difference between C. shanghaiensis and C. formosanus was found in the setae distribution and other characters examined by us, the taxonomic status of C. shanghaiensis needs further investigation. Soldier and winged imagos collected from multiple colonies in the type locality and their molecular sequences are required.	en	Chen, Guan-Yu, Ke, Yun-Ling, Liang, Wei-Ren, Li, Hou-Feng (2020): Redescription of Formosan subterranean termite, Coptotermes formosanus (Blattodea: Rhinotermitidae), with three new synonyms from China.
