Diagnosis

(adapted from Huber 2017). Leaf-dwelling, pale whitish, long-legged pholcids with six eyes and long cylindrical abdomen (Huber 2017: figs 3-19). Distinguished from Calapnita by (1) tibia 2/ tibia 4 length>1.05 (vs. <0.95 in Calapnita); (2) ALS with eight spigots each (vs. two in Calapnita) (Huber 2017: figs 31, 41, 78); (3) proximal lateral processes on male chelicerae in ‘usual’ proximal position (vs. distal in Calapnita) (Huber 2017: figs 23, 35); (4) simple apophysis on male palpal trochanter (vs. hooked and sclerotized in Calapnita) (Huber 2017: figs 21, 34); (5) male palpal femur barely modified (vs. with series of three ventral sclerotized processes in Calapnita) (Huber 2017: figs 21, 34); (6) epigynum roughly rectangular or trapezoidal with folded cuticle and posterior ‘knob’ (vs. triangular with anterior ‘knob’ in Calapnita) (Huber 2017: figs 24, 32, 36, 43). For characters distinguishing Nipisa from similar species in other genera see Diagnosis of Calapnita in Huber (2017).
