Mesabolivar kathrinae Huber, 2015: 8   , figs 4, 11, 26–27, 57–61, 75–77 (♂♀, Brazil: Bahia).

Diagnosis. (amended; see Huber 2015). Easily distinguished from similar congeners ( M. pallens   , M. azureus   , M. brasiliensis   ) by slender procursus (compare Figs 271–279 View FIGURES 271–279 ) (but see Note below) and by epigynum without median pocket (Huber 2015: figs 26, 60; Fig. 296 View FIGURES 292–305 ).

Note. A very similar species occurs in Paraná state (Fazenda Experimental Gralha Azul, 25.667°S, 49.270°W; specimens in ZFMK Ar 19104 and Br10-59; “Br10-4” in Fig. 730 View FIGURES 730–731 ). Males seem to be slightly larger but otherwise identical in all details; females differ by having a shallow but distinct median epigynal pocket ( Fig. 297 View FIGURES 292–305 ).

Description (amendments; see Huber 2015). Tibia 1 in 56 newly examined males: 7.2–10.7 (mean 9.4); in 62 females: 6.3–8.6 (mean 7.4). Male and female leg femora distally wider than proximally; male femora 2 thicker distally than other femora (femora maximum width in large male: 0.17, 0.25, 0.17, 0.18). ‘Valve’ in internal female genitalia sometimes dark and clearly visible through cuticle, sometimes not visible from outside.

Natural history. The spiders were found in weakly domed webs freely suspended among the vegetation, usually about 0.5–1.5 m above the ground. Males and females sometimes shared a web.

Distribution. Widely distributed in NE Brazil ( Fig. 730 View FIGURES 730–731 ).
