Luphocemus insidiosus Denis, 1960

Taxonomic History

1. 1960
   Luphocemus insidiosus Denis, 1960
2. Revalidated, genus and species together. Korba & Opatova (2026) recovered a Moroccan/Algerian clade as reciprocally monophyletic with, and morphologically and ecologically distinct from, Ischnocolus, and revive Luphocemus Denis, 1960 for it — gen. reval. — with this species as its type by monotypy.
3. The name had been through Cyrtauchenius, Leptopelma and Harpactirella before being sunk into Ischnocolus elongatus (Simon, 1873). The holotype (MNHN AR4519) was examined.
4. Luphocemus differs from Ischnocolus in short thick posterior lateral spinnerets with a triangular apical segment, a raised eye tubercle and elevated cephalic region, larger chelicerae with a pseudorastellum, a broad slightly procurved fovea, no tarsal pseudosegmentation, spermathecae without lobes, and — distinctively — lifestyle: it builds a tube burrow with side chambers, lined with dense web and a small turret at the entrance.
5. The male Korba et al. (2022) described as I. elongatus is not conspecific with this species; the authors say a species based on both sexes will be described separately.
