Mistaria zorica (Strand, 1913)  comb. n. Fig. 4

Synonym: Agelena zorica  Strand, 1913 see Strand (1913: 411, ♀), Denis (1950: 499, fig. 9, ♀) and Roewer (1955: 40, fig. 13, ♀)

Type material examined.

Lectotype, ♀, Kenya, Nairobi, 1944, Meneghetti ( NMLS).

Diagnosis.

This species is almost the same size as M. nyeupenyeusi  G.M. Kioko & S. Li, sp. n., but it can be separated by the ovoid shape of the anterior spermatheca lobe compared to the triangular shape in the latter species (Figs 4B, 6B). Epigyne delimiting edge is concave in M. zorica  compared to square in M. nyeupenyeusi  G.M. Kioko & S. Li, sp. n. (Figs 4A, 6A). The general colour pattern of the two species can also be used to distinguish them: M. zorica  is cream-yellow and M. nyeupenyeusi  G.M. Kioko & S. Li, sp. n. is black and white.

Redescription.

Female. Total length 5.4. Carapace 2.0 long, 1.8 wide. Abdomen 3.4 long, 2.4 wide. Habitus as in Fig. 4C, D. Carapace with a distinct pattern of four pairs of lateral bands. Yellow palp with a transverse brown band present on the patellar. Eye sizes and interdistances: AME 0.13, ALE 0.16, PME 0.13, PLE 0.14, AME–AME 0.09, AME–ALE 0.06, PME–PME 0.16, PME–PLE 0.11. Chelicerae and labium red-brown, endites yellow. Sternum brown suffused with black. Legs yellow with an indistinct horizontal black line on the coxa ventrally (Fig. 4D). Leg measurements: III 6.70 (2.10, 2.10, 1.50, 1.00), IV 8.02 (2.11, 2.51, 2.10, 1.30). Legs I and II missing. Abdomen long, ovoid, cream-yellow with no discernable pattern, almost plain. Long posterior spinnerets, three times longer than the anterior spinerets, with the proximal segment, black-brown and the distal segment brown (Fig. 4C).

Epigyne as in Fig. 4A, B. Cream-yellow. Epigyne teeth short and blunt, central origin. Anterior vulva delimiting edge curverd inwards at the middle (Fig. 4A). Copulatory ducts lightly sclerotised, widely separated, vertical length the same as the three retrolateral lobes of spermatheca and position basal (Fig. 4B). Spermathecae longitudinally cover 2/3 length of the pit (Fig. 4B).

Male unknown.
