... of median ocelli, the presence of two pairs of lateral ocelli, and a unique pattern of pedipalp trichobothria. Almost half a century after its discovery, T. vachoni remains known only from the holotype, an adult female collected during a British-Ecuadorian expedition to the Los Tayos Caves, in the Amazonian Region of southeastern Ecuador ( fig. 1), in ...

... only slightly distal to trichobothrium Eb 3 , in T. ballvei (figs. 8A, B, 9A, B), whereas Db is situated submedially on the manus, approximately midway between the Eb and Et trichobothrial series, in T. muranunkae. The macro setae on the telotarsi of legs I-IV are regularly arranged into a pair of parallel ventrosubmedian rows in T. ballvei ( fig. 11E), but not arranged into rows in T. muranunkae and T. vachoni. The ventral and ventrolateral surfaces of the telson are distinctly, coarsely granular in T. ballvei ( fig. 15), but smooth in T. mura­ nunkae. The metasomal LSM carinae are weakly developed, yet distinct, in T. ballvei (figs. 12, 13), but obsolete in T. muranunkae. The VL ...

The macro setae on the telotarsi of legs I-IV are regularly arranged into a pair of parallel ventrosubmedian rows in T. ballvei ( fig. 11E), but not arranged into rows in T. muranunkae and T. vachoni. The ventral and ventrolateral surfaces of the telson are distinctly, coarsely granular in T. ballvei ( fig. 15), but smooth in T. mura­ nunkae. The metasomal LSM carinae are weakly developed, yet distinct, in T. ballvei (figs. 12, 13), but obsolete in T. muranunkae. The VL and VSM carinae are absent on metasomal segment III and comprise coarse granules in the medial third of segment IV, in T. ballvei (figs. 12, 13), whereas both carinae are ...

... III and IV in T. humiculum, and absent on the two segments in the other four species. The hemispermatophore of the new species differs from that of the other Troglotayosicus species for which adult males are known. The lamina is broad proximally and medially, forming two obtuse angles along the dorsal margin in its proximal half, in T. ballvei ( fig. 16), as in T. hirsutus, but markedly expanded medially, not forming angles, in T. humiculum. The apex of the lamina is more elongate in T. ballvei than in other species and slightly coiled, whereas it terminates in a small dilation in T. hirsutus. The ectal lobe (EL) is well developed, with a dorsal process in T. ballvei, similar to that ...

... pronounced in ♂); PD and DMA weakly granular (♂) or smooth (♀). Intercarinal surfaces smooth, with some macro-and microsetae, mostly along carinae, becoming more abundant on fingers. Fixed finger, median denticle row comprising six oblique, slightly imbricate primary subrows of denticles, flanked by five retrolateral and six prolateral denticles (fig. 10B); terminal denticle considerably larger than preceding denticles, hooklike; fingertips interlocking unevenly when closed such that movable finger displaced retrolaterally. Movable finger, median denticle row comprising seven oblique, slightly imbricate primary subrows of denticles, flanked by six retrolateral and seven prolateral ...
