Phan, Quoc Toan, 2018, Notes on the genus Indocnemis Laidlaw, 1917 in Vietnam with description of Indocnemismarijanmatoki sp. n. (Odonata, Zygoptera, Platycnemididae), ZooKeys 809, pp. 15-29 : 18-19

Indocnemis orang ( Foerster in Laidlaw, 1907) forma kempi Figures 5, 6, 9, 10

Examined specimens.

1 mature male, 1 mature female, Cuc Phuong National Park, Ninh Binh Prov., 25 June 2018, Q.T. Phan leg.

Remarks.

Asahina (1997) did not describe the colour of the dorsal stripes on synthorax of his orang forma kempi from Cuc Phuong. I can now confirm that the dorsal stripe of the mature living male of this form in Cuc Phuong is blue (Fig. 9). Asahina (1997) also did not mention the pale yellowish appendages of the males from Cuc Phuong (Fig. 10). Females of the two forms orang and kempi can be separated by their body pattern: the yellow spot on the middle lobe of prothorax and lateral stripes on synthorax in forma kempi are smaller (Fig. 5) than those in forma orang (Fig. 3); the bluish markings on dorsal S9-10 in forma kempi are smaller and in forma orang ; and S8 is black, without yellow marks as in forma orang (Figs 4, 6). In female forma kempi in Cuc Phuong, the structure of the posterior lobe of the prothorax is the same as in the female of forma orang .
