Tribe Echinantherini Zaher et al., 2009

This tribe is represented by the genera Echinanthera and Taeniophallus (Zaher et al., 2009) , they have hemipenis unilobed and uni capitate. Sulcus spermaticus is divided relatively distally in the calyculate area, and there is a large nude area in the asulcate side of the hemipenial body (Zaher et al., 2009). Both genera are morphologically similar, with a slender body, aglyphous dentition, and circular pupils ( Di-Bernardo, 1992). Taeniophallus bilineatus can be distinguished from the other species by the number of ventral scales (> 140) ( Di-Bernardo & Lema, 1990), and the other species from this tribe can be identified by its cephalic and dorsal marks ( Di-Bernardo, 1992; Di-Bernardo & Lema, 1986).
