  On the first Subandean species of Myrmecium Latreille, 1824 (Araneae, Corinnidae) from the Cordillera del Cóndor, Ecuador  The ant-mimicking spider genus Myrmecium Latreille, 1824, revised by Candiani & Bonaldo (2017), can be diagnosed from other Castianeirinae by the presence of three deep constrictions of the cephalothorax, the long and obliquely inserted pedicel, the sternum posterior margins projected between coxae IV, generally forming a T-shape, pleural sclerites between legs III and IV fused with the sternum and carapace, and coxae III and IV almost vertically oriented and separated by more than twice the width of coxa III (Candiani & Bonaldo 2017).

Running crab spiders (Araneae: Philodromidae) from Colombia: new species and records

Abstract
We present new records and species of running crab spiders (family Philodromidae) from Colombia representing four genera: Apollophanes O. Pickard-Cambridge, 1898, Gephyrellula Strand, 1932, Petrichus Simon, 1886, and Tibelloides Mello-Leitão, 1939. The genus Gephyrellula is recorded based on the newly described G. lavidabonita sp. nov., known from females from the department of Magdalena, constituting the northernmost known locality for the genus, at Sierra Nevada de Santa Marta. This new species can be differentiated from the (previously monotypic) type species G. violacea (Mello-Leitão, 1918), known from southeastern region of Brazil, by the longer than wide epiginal plates (wider than long in G. violacea), with narrower and shorter ducts of the glandular heads (thicker and longer in G. violacea), and by their more posteriorly placed fertilization ducts. The genus Apollophanes is here firstly recorded from males and females of A. punctipes (O. Pickard-Cambridge, 1891) from the Atlántico, Magdalena, Cesar, Cundinamarca, and Boyacá departments. Tibelloides is recorded from males and females of T. bryantae (Gertsch, 1933), from the departments of Magdalena and Meta, also representing northernmost known localities for the genus. Finally, new faunistic and taxonomic data is presented for Petrichus. Our examination of the holotype of Thanatus granadensis Keyserling, 1880 demonstrates this species is conspecific with more recently collected and better-preserved specimens of Petrichus griseus Berland, 1913, from the department of Santander. Therefore, we propose the new combination Petrichus granadensis comb. nov., regard P. griseus as its junior synonym syn. nov., and update knowledge of its distribution.
