Precision Lost with Complexity: On an Extraordinary New Species of Pholcidae (Araneae, Smeringopinae) from Western DR Congo

Abstract

A remarkable new pholcid spider species is described from the Democratic Republic of the Congo: Smeringopina polychila sp. nov. The male is distinguished by a unique and previously undocumented structure, here termed the “parachila”, which has not been observed in any other spider to date. The description is complemented by high-quality illustrations, including detailed drawings, photographs, micro-CT scans, and 3D reconstructions of the genitalia and the newly discovered male structure. Remarkable intraspecific variations, both somatic and genitalic, in males are also highlighted and discussed. A phylogenetic analysis based on the cytochrome c oxidase subunit I, 16S ribosomal RNA and histone H3 gene fragments is presented to tentatively place the new species into an existing phylogenetic framework. The results of the molecular analyses confirm that the new species belongs to the subfamily Smeringopinae and is nested within the genus Smeringopina Kraus, 1957.
