Spinopilar Mello-Leitão, 1940


Spinopilar Mello-Leitão, 1940  

Spinopilar Mello-Leitão 1940: 102   . Kury 2003: 204; 2014: 24.

Type species. Spinopilar armatus Mello-Leitão, 1940   (by original designation)

Placement. Spinopilar   originally described in Phalangodidae   Tricommatinae. Transferred to Cryptogeobiidae   by Kury (2014).

Etymology. Spinopilar   from Latin spîna (thorn) + toponym Pilar. Gender masculine.

Diagnosis. Stigmatic area fused to Cx IV along most of their area of contact ( Figs 6A View FIGURES 6 , 16B View FIGURES 16 ). Some species bear a stridulatory organ matching the ectal surface of basichelicerite and mesal surface of Pp Fe ( Figs 17C–E View FIGURES 17 , 22B–D View FIGURES 22 ). Distalmost megaspine of Pp Ti much longer than the others ( Fig. 7C View FIGURES 7 ). Cx IV of male with retroventral L-shaped apophysis with ectal branch fasciolate ( Figs 11B, D View FIGURES 11 ). Tr IV of male with well-developed retrolateral apophysis, with secondary fasciolate branch associated with a PTC ( Figs 21A–F View FIGURES 21 ). Malleus with a dorsobasal hyaline haematodocha (DHB, Figs 9C View FIGURES 9 , 25B View FIGURES 25 ). Skirt with short stem, flabellum wide and short with individual barbels deeply serrate ( Figs 9E, F View FIGURES 9 , 19I View FIGURES 19 , 25D View FIGURES 25 ).

Species included [with indication of WWF Ecoregions]. Spinopilar anomalis (Sørensen, 1932)   [NT0150], Spinopilar apiacaensis Kury, 1992   [NT0104], Spinopilar armatipes (B. Soares, 1972)   [NT0150], Spinopilar armatus Mello-Leitão, 1940   [NT0160], Spinopilar friburguensis (H. Soares, 1946)   [NT0160], Spinopilar insignitus ( Roewer, 1949)   [NT0101], Spinopilar jocheni   spec. nov. [NT0160], Spinopilar magistralis   spec. nov. [NT0160], Spinopilar martialis   spec. nov. [NT0102] and Spinopilar moria Kury & Pérez-González, 2008   [NT0704, cavedwelling].

Distribution. Brazilian Atlantic Forest: states of Espírito Santo, Minas Gerais, Rio de Janeiro, Santa Catarina and São Paulo. Argentina (extreme NE), Paraguay (extreme E), both in the Atlantic Forest domain. Occurrence in Paraná state is highly likely. The presence of so many closely related species of cryptogeobiids in a relatively small area indicates high micro-endemism of those leaf-litter dwelling Laniatores and allows the prediction of a great number of undescribed species in the Brazilian Atlantic Forest, most of which are probably extinct due to heavy deforestation of that area ( Fig. 2 View FIGURE 2 ).
