Species group characters
Teunipalpus caudatus species group
Characters
- setae c2, d2, e2 absent (Figs. 1-4)
- prodorsum mostly smooth with some weak areolae centrally; series of longitudinal-oblique folds laterally (Fig. 5)
- dorsal opisthosoma mostly smooth, with a few wrinkles (Figs. 1, 2, 4)
- setae f2, f3, h1 thick, curved (Figs. 3, 4)
- ventral plate not developed; cuticle posterior to setae 4a1-2 with transverse striae forming an oval shape (Figs. 6, 7, 8)
- genital plate weakly developed; cuticle between ag and g1-2 usually with broken striae forming patterns of short "dashes" (Figs. 6, 8), or cuticle with unbroken striae
- ventral lateral cuticle anterior to coxae III and lateral to setae 3a1-2 with a distinct pebble-like pattern (Figs. 9-10)
- ventral setae 3a and 4a are doubled = 3a1-2, 4a1-2 present (3a1 < 3a2; 4a1 = 4a2)
- palp tarsus with a long straight solenidion and a short, curved tapered seta (Figs. 11, 12)
- anterior margin of prodorsum with a forked projection, variable in shape and length - with two central projections flanked by two reduced projections/bumps (Fig. 13)
- male similar to female (Fig. 14)
