Strandesia flavescens Klie, 1932

( Figures 8A, B , 9A, B )

Remarks

Since Klie’ s (1932) original description of this large (length approximately 2 mm), conspicuous species from Indonesia, it has only been reported twice more, from India ( Victor and Fernando 1979b) and Taiwan ( Yu et al. 2009, citing grey literature). Victor and Fernando (1979a) were of the opinion that S. flavescens is a junior synonym of Strandesia odiosa ( Moniez 1892) , after they redescribed the types of S. odiosa , although this was not followed by later authors (e.g. Savatenalinton and Martens 2010). The slightly lower lateral view of the carapace and the list on the anterior calcified inner lamella of the left valve (marked by black triangle 1 on Figure 9A ) of S. flavescens discriminate the two species. Additionally, S. flavescens has a series of septa-like structures in the internal part of the margins of the left valve (marked with black triangle 2 of Figure 9A ), which are not mentioned or figured in Victor and Fernando’ s redescription of S. odiosa . Because Victor and Fernando (1979a) considered the two species as synonyms, is not clear whether the previous Indian report is of S. flavescens or S. odiosa . Only one specimen of this species was collected during our surveys, from a lotus pond (locality 6).
