Q.The clitellum is a distinct part in the body of earthworm Lampito mauritii, it is found in?

Lampito mauritii (Phylum Annelida, Class Oligochaeta, Order Haplotaxida) is a terrestrial, burrowing worm common in Tamil Nadu, with a long, cylindrical, bilaterally symmetrical body 80-210 mm long, divided externally into 165-190 ring-like segments (metameres). Key identifying landmarks include the anterior mouth (peristomium) overhung by the prostomium, the posterior anus (pygidium), a swollen glandular clitellum on segments 14-17 (used to separate the body into pre-clitellar, clitellar and post-clitellar regions), rings of S-shaped chitinous setae on most segments, and openings such as the dorsal pores, three pairs of spermathecal openings and separate male and female genital pores. Earthworms are also grouped ecologically as epigeics, anecics or endogeics depending on how deep in the soil they live and feed - Lampito mauritii is an anecic, upper-soil species. These external features, together with segment counts and organ positions, are exactly what is used to tell one earthworm species apart from another, as in the standard comparison with Metaphire posthuma.
