The species name bengalicus is derived from the type locality, West Bengal.	en	Kayal, Sandipan, Mondal, Priyankar, Karmakar, Krishna (2022): The first record of Ceratotarsonemus (Acari: Tarsonemidae) from the Oriental region with description of a new species from West Bengal, India.

D93687A22A5CFF9C84EE1ED0FA7A83D8.taxon	diagnosis	Differential diagnosis. Ceratotarsonemus bengalicus sp. nov. is unique in the genus because of having the prodorsal shield with medial irregular striation, several cells posterior to them arranged in semi-ovate area, and the medial part of sejugal apodeme convex posteriorly. Among previously known species of the genus, C. bengalicus sp. nov. is closest to C. amazonicus in sharing the following characters: tergite C has uneven reticulation consisting of four rows of irregular cells, setae c 2 and e are long, setae c 1 are longer than c 2, apodemes 1 are conspicuous and joined to the anterior end of prosternal apodeme, the poststernal apodeme is bifurcate anteriorly, and tibiotarsus of leg IV is about 8 long. The new species differs from C. amazonicus in having the following features: the medial part of tegular margin is convex and lateral parts are with two small angular projections on either side (vs. tegular margin concave in C. amazonicus); scapular setae sc 2 are about 1.2 times longer than setae v 1 (vs. setae sc 2 nearly twice longer than v 1); setae h are considerably longer (41 – 44 vs. 23 – 26); coxisternal setae 2 a are twice longer than 1 a (vs. 1 a and 2 a subequal), setae 3 a are over than 2.5 times longer than 3 b (vs. 3 a and 3 b nearly equal in length); apodemes 3 are diagonally stretched from the anterior end of trochanters III and slightly curved (vs. wavy and median ends slightly bent posterior); on legs I, tarsal solenidion ω is shorter (3 – 4 vs. 6 – 7), famulus k is shorter (2 – 3 vs. 5); on legs II, tibial seta d is considerably longer (19 – 22 vs. 12 – 13).	en	Kayal, Sandipan, Mondal, Priyankar, Karmakar, Krishna (2022): The first record of Ceratotarsonemus (Acari: Tarsonemidae) from the Oriental region with description of a new species from West Bengal, India.
