SELKIRKIELLA BERLAND, 1924 View in CoL View at ENA
Selkirkiella Berland, 1924 , type species by monotypy Selkirkiella alboguttata Berland, 1924 , not examined.
Removed from synonymy of Anelosimus contra Levi (1972: 536). In addition to S. alboguttata (Berland, 1924) , several former Anelosimus species are transferred and the following new combinations established: S. carelmapuensis (Levi, 1963) , S. luisi (Levi, 1967) , S. magallanes (Levi, 1963) , S. michaelseni (Simon, 1902) , S. purpurea (Nicolet, 1849) , S. ventrosa (Nicolet, 1849) , and S. wellingtoni (Levi, 1967) .
Synapomorphies of Selkirkiella in this study ( S. alboguttata and S. magallanes ) include: conductor enlarged and fan shaped (63, Fig. 67A, C View Figure 67 ), conductor heavily ridged (65, Fig. 67C View Figure 67 ), TTA apex with small apophysis (82, Fig. 67A, B View Figure 67 ), SPR ectally orientated picks absent (153, Fig. 67F View Figure 67 ), grooved SPR region (155, Fig. 67F View Figure 67 ), and elongate FL spigot (206, Fig. 68E View Figure 68 ). Also, characteristically in Selkirkiella the conductor and TTA are strongly compressed together, separated by a narrow seam ( Fig. 67B View Figure 67 ). Based on Levi’s (1963, 1967) drawings and descriptions, at least the enlarged and fan shaped conductor, TTA apex apophysis, and TTA and C compressed are universal in Selkirkiella .
Diagnosis
Selkirkiella differs from related pholcommatines by the shape and texture of the conductor, TTA apophysis, TTA and C compressed, lack of ectally orientated SPR, and possibly by mode of egg-sac protection, where a small sheet is woven to cover the egg sac ( Fig. 95E View Figure 95 ).
