Zachaeus

Zachaeus crista, copyright Ondřej Machač.

Belongs within: Phalangiidae.

Zacheus is a genus of large-bodied phalangiid harvestmen found in the eastern Mediterranean and western Asia (Kurt et al. 2015). Historically, there has been confusion regarding the correct spelling of the genus name; Crawford (1992) provides reasoning for use of the spelling 'Zachaeus'.

Characters (from Kurt et al. 2015): Body large, heavily denticulated dorsally; chelicerae usually strong, second segment enlarged; pedipalps normally structured, strong, robust; legs short, first pair much thicker than others; truncus of penis basally widened, parallel-sided on distal half, distally shallow spoon-shaped, glans usually banana-shaped (shorter in Z. anatolicus and Z. seyyari), stylus long.
