Female Metarthrodes longipes, copyright Edelcio Muscat.

Belongs within: Gonyleptidae.

The Caelopyginae are a group of gonyleptid harvestmen with a wide, medially depressed eyemound found in the Atlantic and Araucaria forests of southern Brazil (Pinto-da-Rocha 2002).

Characters (from Pinto-da-Rocha 2002): Body subrectangular or pyriform. Scent glands with two external openings (ozopores) on each side. Eye mound wide, with a median depression, with one low tubercle near each eye (rarely smooth or with one pair of large tubercles). Dorsal scute with four grooves (three areas). Area I divided. Area III with two spines with blunt apex (rarely more acute) or two tubercles. Posterior margin of dorsal scute, from straight to concave. Pedipalp with femur thin, cylindrical (smaller than length of dorsal scute), without wide ventral setae; patella without prolateral seta; tibia mesal IiIi, ectal IIi/IiIi/IiiIi; tarsus longer than tibia, biconvex, with two ventral rows of wide setae, ecta II, mesal II (rarely I). Tarsus with more than six segments; III–IV with semispherical articles, distitarsus I 3-segmented, II 4- or 5-segmented (rarely 3-), with a dense scopula. Claws bipectinate. Tarsal process present and long. Penis with ventral process of glans long and thin; dorsal process absent; basal lobe of ventral plate forward; 3–4 pairs of distal setae of ventral plate longer than other; two short setae behind distal group of setae (sometimes a little above the long ones; rarely absent); one intermediary seta (between the long and the basal groups); 3–4 pairs of long basal setae, the basal one reduced, absent or long. Yellow to greenish coloured, with or without white spots or dots on dorsal scute, free tergites and dorsal and ventral anal opercula.
