Lycinus caldera
''Lycinus caldera'' is a mygalomorph spider of Chile, named after its type locality: Caldera, Copiapó, Region III.〔Goloboff, Pablo A. "A revision of the South American spiders of the family Nemesiidae (Araneae, Mygalomorphae). Part 1, Species from Peru, Chile, Argentina, and Uruguay. Bulletin of the AMNH; no. 224." (1995).〕 Males are distinguished from ''L. gajardoi'' by the larger cymbium, the thinner and more numerous modified cymbial setae and the shorter embolus, and from those of all other species in the tribe by having cymbial setae directed backwards. Females are distinguished from other Chilean species of Lycinus by the spermathecae with two or three receptacula on each side.
