The present study provides a description of the histological organization of the mesentero-proctodeal regions (midgut and hindgut) of adult Epicauta waterhousei (Haag-Rutenberg, 1880). The histological wall of the mesentero-proctodeal regions consists of 4 layers; mucosa, submucosa, muscularis and serosa layers, respectively. Midgut was classified into 3 subparts based partially on the size and characterization of the longitudinal fold; pro-midgut, meso-midgut and hind-midgut. Among these subparts, the longitudinal fold of the hind-midgut becomes progressively higher than other subparts. The mucosal epithelial lining of the midgut is a single layer of simple cuboidal epithelium. Hindgut is classified into 2 subparts; illium and rectum. These parts are lined by simple cuboidal epithelium with a surrounding thick layer of muscularis (inner circular and outer longitudinal muscular layers). However, the muscular layer of the rectum is thicker than the ilium. The present study provides baseline information about structural histology, but further fine descriptive investigation may be needed. doi:10.14456/WJST.2014.75
