Chilocosmia dichromata is a species of selenocosmiine tarantula, in the Phlogiellini tribe.[1]
Taxonomy
[edit]This species was originally described as Chilocosmia dichromata by Schmidt & von Wirth, in 1992.[1] In 2005, Peters changed the name to Selenocosmia dichromatus,[2] and in 2012, West, Nunn & Hogg placed Chilocosmia (along with C. dichromatus) as a junior synonym of Orphnaecus, creating the combination Orphnaecus dichromatus.[3] In 2025, Acuña, et al., found the genera sufficiently different to remain separate, re-classifying the species as Chilocosmia dichromata.[4]
Characteristics
[edit]C. dichromata has 10 large (and some small) teeth on the chelicerae in a row. It also has 4-5 rows of strikers (also on the chelicerae), that are basally thickest and longest. The 3 rows 10 unequal coxal strikers are clavate (scimitar shaped) and arranged in a semicircular shape. The cephalothorax, coxae and trochanter are reddish-brown and the abdomen and other leg segments are brown.[5]
