Shuyushka View in CoL gen. nov.
urn:lsid:zoobank.org:act:22C28CEB-BAE6-4902-8657-9A922D775514
Type species
Shuyushka wachi gen. et sp. nov.
Diagnosis
Shuyushka gen. nov. can be distinguished from other Anyphaeninae genera by the presence of the following characters: tracheal spiracle in the middle of abdomen; lateral margin of endites concave; posterior eye row procurved; prolateral apex of tibia I with patch of short setae ( Fig. 40 View Figs 37 – 40 ). From WulFlopsis Soares & Camargo, 1955 by the presence of ventral patellar apophysis ( Figs 29 View Figs 27 – 31 , 34 View Figs 32 – 36 , 39 View Figs 37 – 40 ) absent in the latter genera; from Thaloe Brescovit, 1997 by the absence of medial projections on the lateral margin of the endites, present in the latter (Brescovit 1997: Fg. 41). Females of Shuyushka gen. nov. are also distinguished by the absence of lateral epigynal grooves ( Figs 30 View Figs 27 – 31 , 35 View Figs 32 – 36 ).
Etymology
The generic name is taken from the Kichwa language meaning ‘spotted’ for the dark marks on the abdomen. The gender is feminine.
Composition
Shuyushka achachay gen. et sp. nov., S. moscai gen. et sp. nov. and S. wachi gen. et sp. nov.
Distribution
Ecuador.

Eight eyes; AME smallest, less than half the diameter of the others; LE-PME about the same size; AME touching; AME-ALE almost touching, LE contiguous, LE-PME separated by half their width; PME separated by half their width; posterior eye row slightly procurved in dorsal view ( Fig. 27 View Figs 27 – 31 ).
LEGS. Trochanters notched; scopula sparse, entire on metatarsi and tarsi I–II; absent on metatarsi III–IV, entire on tarsi III–IV; apex of metatarsi III–IV with apical brush; prolateral apex of tibia I with patch of short setae ( Fig. 40 View Figs 37 – 40 ).
