Everettia paulbasintali Liew, Schilthuizen & Vermeulen 2009
“Diagnostic characteristics: Shell surface with densely placed radial threads.” (Liew et al., 2009)
“Remarks: Some of the populations on the left bank of the Segama river (area around Imbak Valley, Danum Valley, and Kinabatangan) have coarser radial threads and these are cut by more closely placed spiral grooves than in the populations with typical sculpture from the right bank of the Segama river (Tabin and Tawau area).” (Liew et al., 2009)
Liew et al. (2009) descriptions on Everettia paulbasintali – “Shell: large, rather thin, yellowish brown. Spire moderately elevated, outer whorls slightly shouldered below the suture. Periphery slightly shouldered to almost rounded, more distinctly angular in juveniles. Above the periphery, shell silky with very densely placed radial threads and somewhat cut by irregularly spaced spiral grooves. Below the periphery, shell has fine, densely placed spiral grooves. …number of whorls up to five and a half…”
“Animal: black bands on either side of the tentacles separated by a white band that occupies the space between the eye tentacles, and extends backward to the end of the mantle and downward to just below the eye tentacles. Other parts of the animal are covered by regularly spaced oblique dotted belts. The mantle is covered by black irregular markings and followed by regularly spaced radial darker brown bands at the last half whorl.” (Liew et al., 2009)
“Genitalia: maximum length from genital opening to the end of dart-sac (before the visible gland tubules) up to 14 mm. The penis, dart-sac, and vagina with thick muscular walls. Penis, vagina, genital opening, bursa copulatrix, and dart-sac arranged around the short genital atrium, limited space between the openings of each of the genital structures. Bursa copulatrix about one-quarter to one-third of total dart-sac length.” (Liew et al., 2009)
