Karllangia arenicola bengalensis Wells & Rao, 1987 Original description. Wells & Rao (1987) : 131–132; Fig. 110; Table 7. Type locality. Andaman and Nicobar Islands : North Andaman, Mayabandar, Seaward Bay ( 12°52’06”N , 92°56’48”E ); algal sand rich in detritus; fine to medium sand with a small amount of shell gravel; taken from surface to 20 cm deep between low and half-tide levels. Notes. Wells & Rao (1987: 132 , 218; Table 7) considered their specimens to be more or less intermediate between K. arenicola s.str. and K. psammophila . They considered all three of them as morphs of a single polytypic species and granted subspecific status to each of these potentially allopatric “populations”. Gee (2006: 2644) reexamined material of K. psammophila and, consequently, reversed the situation by resurrecting them as valid species. According to Wells & Rao (1987 : Fig. 110c) the female antennary exopod of T. bengalensis comb. nov. differs from the typical condition in bearing only one lateral seta on exp-2. In addition to the type locality, the species was also recorded from the Sawai Bay of Car Nicobar Island ( Wells & Rao 1987 ).
