Diagnosis. Nops blandus resemble similar congener Nops finisfurvus (Fig. 15C‒D) by having a short and weakly curved embolus in males and a wide invagination on receptaculum of female genitalia, but can be distinguished by having a widest embolar base (Fig. 9H, J), and the invagination on receptaculum is only one time the wide of the lobes (Fig. 10G), in N. finisfurvus is three or four times widest (Fig. 15G).
Description. Male and female described by Sánchez‒Ruiz et al. (2015). Adding the following: Males and females with abdominal pattern as in figure 6I; posterior unpaired claws elongated and dorsally reflexed; and PLS longer than PMS. Females with external genital area with strongly sclerotized anterior plate, strongly sclerotized lep and remarkable ess (Fig. 10F). Internal genitalia with a wide invagination on receptaculum and uterus externus with a wide base (Fig. 10G).
Variation. Males from Virgin Gorda Island have the base of embolus slightly wider. Males and females from Lameshur, Saint John have slight differences in genitalia, size and coloration compared with other Saint John specimens. Male from Little Saint James (BSC 656) have embolus narrower and slight differences in median part compared with males from Saint John.
Distribution. Known only from British and U. S. Virgin Islands (Fig. 8E).
