2015

= Estheria similis Baird, 1849

= Bairdestheria similis ( Baird, 1849)

= Pseudograpta similis ( Baird, 1849)

Comments: The type locality is given as “ India ”. Tiwari (1996) treats C. annandalei and associated synonyms, as well as C. similis all as junior synonyms of C. boysii . However, Rogers and Padhye (2015) reported that the types of C. boysii and C. similis are empty, dried carapaces; useless for determination. Furthermore, Daday (1914) was unable to differentiate between the two forms, and could not separate the types from any other Eurasian form, and treated both taxa as species inquirendae. Baird’s description of these two species is entirely based on carapace characters, giving the type locality for both as “ India ”.
