Diagnosis. Relatively large-sized species, juxtaocular bulge tapered. Median secondary distal process of ventral phallomere highly developed, slightly curved, gradually tapering to a sharp apex; lateral secondary distal process small, sharp, and turning to the right ( Figure 5 View Figure 5 (a–e)).

Measurements (mm). Body length: male 20.60–20.80, female 25.12–25.20; pronotum length: male 2.26–2.29, female 2.72–2.78; length of fore femora: male 3.30–3.35, female 3.95–3.40; length of middle femora: male 5.39–5.43, female 5.77–5.82; length of hind femora: male 5.95–6.00, female 6.65–6.71; length of tegmina: male 17.89–18.02, female 18.68–18.80; length of cerci: male 2.66–2.74. female 2.69–2.80; head width: male 4.59–- 4.62, female 5.84–5.90.

Notes. Ootheca is small, about 5–7 mm long, with a slender residual process, filamentous, and laid in crevices of tree bark ( Figure 8 View Figure 8 (b)). There are about 6– 8 eggs in an ootheca. In Nanjing, the Amorphoscelis chinensis has been observed to prey on the Crematogaster sp. ( Hymenoptera : Formicidae ) on the tree trunk, implying that it may be monophagous.

Discussion. The holotype of A. chinensis was originally kept in Ling’Nan Natural History Survey and Museum ( Tinkham 1937) and might have been transferred to Sun Yat-sen University at some point. However, we could not locate the specimen when examining mantis material in the university collections. After comparing the structures of the male genitalia of topotypes with a photograph of the male genitalia ( Svenson 2014) of one paratype that was collected from Yunnan and deposited in the Museum of Natural History, Smithsonian Institution, USA, we think all of these specimens are conspecific due to similarity in the shape of the male genitalia.

A comparison of specimens of A. chinensis Tinkham with the type of A. stellulata and the type of A. phaesoma reveals that there are no striking differences in the shape of the genitalia among these species, despite variation in colouration, linear morphometric measurements and male cercal shape ( Figure 4 View Figure 4 (a–c,j–l)).Thus, we propose that A. stellulata and A. phaesoma are actually synonyms of A. chinensis . Roy (2011) also reported a record of A. stellulata from Hangzhou, which should now be regarded as a record of A. chinensis .

Distribution. China (Guangdong, Fujian, Jiangxi, Zhejiang, Jiangsu, Henan, Guangxi); Vietnam ( Roy 2011). Amorphoscelis chinensis Tinkham may be distributed in Nanjing, Jiangsu (32.04°N), which is currently the northernmost limit of the Chinese distribution for the genus Amorphoscelis .
