Mitobatinae

Neoancistrotus gracilis, copyright Osvaldo Villarreal Manzanilla.

Belongs within: Gonyleptidae.

The Mitobatinae are a group of gonyleptid harvestmen with a usually elongate, unarmed femur IV in the male (Bragagnolo & Pinto-da-Rocha 2012).

Characters (from Bragagnolo & Pinto-da-Rocha 2012): Anterior margin of prosoma with frontal hump present and unarmed. Armature of ocularium usually with two spiniform apophyses. Armature of scutal areas variable, area III usually armed with pair of spiniform apophyses. Usually four areas on dorsal scutum; sometimes areas III and IV fused. Posterior margin may be armed with pair of tubercles. Free tergites unarmed or with median tubercles. Chelicera of similar size in both sexes. Femur of pedipalps only with short and thick ventral apical setae, patella and tibia unarmed. Coxa IV dorsally visible in entire extension in both sexes, with dorsoapical apophysis that can be robust and bifid in males (sexual dimorphism) or extremely reduced. Male femur IV straight and usually much elongated, usually more than four times scutal size, rarely about three times, and usually unarmed. Penis with ventral plate well defined, usually pyriform (sometimes rectangular), with setae on distal margin. Ventral process present; dorsal process absent. Stylus elongate, usually straight.
