Evolution of genital asymmetry, exaggerated eye stalks, and extreme palpal elongation in Panjange spiders (Araneae: Pholcidae)
We describe several new species of the previously monotypic <em>Panjange lanthana </em>species group from the Philippines and document their extraordinary morphology. Some species show strong male genital asymmetry, a phenomenon that seems to be exceedingly rare in spiders. Males of most...

| description | We describe several new species of the previously monotypic <em>Panjange lanthana </em>species group from the Philippines and document their extraordinary morphology. Some species show strong male genital asymmetry, a phenomenon that seems to be exceedingly rare in spiders. Males of most species have eye stalks, and in two species these eye stalks are among the longest ever recorded in spiders. Some species show a tendency for male genital (pedipalp) elongation, and one species has the longest and thinnest palps ever recorded in Pholcidae. A cladistic analysis is performed including all described and several undescribed species of <em>Panjange</em> (except for one “problem species”), supporting the <em>lanthana</em> group and its close relationship with members of the possibly paraphyletic <em>cavicola</em> group. The following eight new species are described: <em>Panjange malagos</em> Huber sp. nov.;<em> Pa. casaroro </em>Huber sp. nov.; <em>Pa. camiguin</em> Huber sp. nov.; <em>Pa. hamiguitan </em>Huber sp. nov.; <em>Pa. isarog </em>Huber sp. nov.; <em>Pa. dinagat </em>Huber sp. nov.; <em>Pa. marilog</em> Huber sp. nov.; <em>Pa. bukidnon</em> Huber sp. nov. |
