8-10): Tergites 1 to 4 weakly sclerotized, tergites 6 and 7 completely sclerotized, tergite 8 as narrow sclerotized band, all tergites with single row of setae along posterior margin,
trichoid sensilla absent.
Pterothorax: Trapezoidal, lateral margins slightly divergent, posterior margin convex, forming fine lateral ends; pteronotum not divided; pteronotal postero-lateral marginal setae five to six on each side, arrangement 4,2+2,4 (4 latero-posterior and 2 posterior setae);
trichoid setae present, thorn like setae present; mesothoracic spiracles ventral in position; proepimeron expanded posteriorly and separated in median; mesofurcal pit present; meso-metasternal plate elongated and narrow, with one pair of normal fine seta on each.
Abdomen (Figure 9): tergites 1-6 sclerotized, rectangular, with a distal row of setae, few setae mesally and laterally, basal pair of
trichoid sensilla, and scattered scales; tergites 7 and 8 sclerotized, elliptical, with only a basal pair of
trichoid sensilla.
On its surface, these segments presented
trichoid cuticular sensilla (Figure 2).
Near the labial tip on the dorsal and ventral sides one pair of
trichoid sensilla (TRS) was found (probably bimodal sensilla: mechanoreceptors and gustatory) (K23 (0) and K25 (0)).
In the superior margin, it has a lock of sensitive hair and laterally, a
trichoid sensilla of tactile function.
Lee and Craig (1983) made a detailed study of the cibarial sense organs: palatal papillae (pp), campaniform sensilla (cs), dorsal papillae (dp),
trichoid sensilla (trs) and ventral papillae (vp).
Scutum with 2 rows of dorsocentral setae, anepimeron with 10 setae, laterotergite with 2
trichoid sensilla, other sclerites bare.
(2012) reported the presence of larger cylindrical
trichoid sensilla on the rostrum of Lissorhoptrus oryzophilus (Coleoptera: Curculionidae).
Seventh tergite rectangular, much smaller than sixth, with pair of
trichoid sensilla anteriorly, single row of setae along posterior margin, elsewhere covered with scales.

trichoid sensilla exhibit nanoscale-level heterogeneity in surface lipid properties," Arthropod Structure and Development, vol.
4 with filiform
trichoid sensillae, with about 22 serrulae; serrulae at centre saddle-shaped, broadly rounded at apex, with about 3 or 4 flat, irregular posterior subbasal denticles and two small anterior sub-basal denticles (Fig.
