Type material

Holotype

INDIA • subadult ♀; West Sikkim, Bank of Great Rangeet (= Rangit) River ; 20 Sep. 1959; B.K. Tikader leg.; NZC-ZSI, Kolkata (no register number specified).

Paratypes

INDIA • 4 subadult ♀♀; same collection data as for holotype; NZC-ZSI, Kolkata (no register number specified) .

Allotype

INDIA • subadult ♂; same collection data as for holotype; NZC-ZSI, Kolkata (no register number specified).

Note

We examined the holotype, paratypes and allotype of S. joyaus ( Fig. 12 A–E) and found that these were all subadults, thereby, the morphology of its female genitalia remains yet unknown. Jocqué & Bosmans (1989) described the male of this species based on non-type material deposited in BMNH, London, that were collected in Sikkim. Without referring this, Sen et al. (2015) claimed that they had provided the first description of the male of S. joyaus . It is surprising that, even though they had two female specimens at hand, they never attempted to illustrate its genitalia, instead illustrated the male genitalia that was already well illustrated ( Jocqué & Bosmans 1989: figs 11–12).

Remarks

The ZSI collection has three glass tubes for this species. First tube labeled as “ holotype ” (no register number) contains one subadult female specimen in good condition, with intact genitalia. Second tube labeled as “ paratype ” (3232/18) contains four subadult female and one juvenile specimens in good condition. Third tube labeled as “ allotype ” (3231/18) contains one subadult male specimen in good condition.
