Deione Thorell, 1898 View in CoL

Deione Thorell, 1898: 365 View in CoL ; Bonnet, 1956: 1379; Murphy & Murphy, 2000: 87, Fam.15: fig. 2; Roewer, 1942: 761.

Type species. Deione thoracica Thorell, 1898 View in CoL , by monotypy.

Diagnosis. Deione can be distinguished from other araneid genera, like the South-East Asian genus Artonis , by the presence of four humps in two rows on the distal end of the abdomen ( Fig 2 View FIGURES 1–5 ), two pairs of short and thick macrosetae on anterior abdomen, two strong ventral macrosetae near the distal end of tibia II, two short, blunt macrosetae ventrally on basal metatarsus in the male, and by the broad, trapezoid epigynal scape in the female. The abdomen shape of Deione is similar to that of Chorizopes , but can be distinguished by the widely separated posterior median eyes ( Fig. 3 View FIGURES 1–5 ), flat cephalic region, the presence of two macrosetae on male palpal patella, the absence of paramedian apophysis, and the median apophysis flat with wide and smooth edge.

Description. Carapace longer than wide ( Figs 1 View FIGURES 1–5 ; 14–15 View FIGURES 14–17 ). Cervical groove distinct. Cephalic region long, posteriorly raised. Thoracic region short relative to cephalic region, low, round in sides. Both eye rows recurved, posterior median eyes largest, widely separated. Clypeal height equals the AME diameter. Sternum longer than wide, truncated on anterior margin. Chelicerae strong, promargin with five teeth and retromargin with three, anterior edge embowed. Labium and endites wider than long. Legs short and thin, with few macrosetae. Leg formula: 1243. Abdomen oval, with humps at the top of posterior abdomen. Spinnerets situated under distal end of abdomen. Epigynum with short, wide scape, one hood at the top ( Figs 4–5 View FIGURES 1–5 ). Male palpal patella with two macrosetae; conductor wide, membranous; embolus flagelliform, median apophysis wide; terminal apophysis with hook; paramedian apophysis absent. Tibia II with two large, ventral macrosetae at distal end, the base of metatarsus with one or two short, blunt macrosetae ventrally.

Distribution. China, Myanmar.
