Comment | Synonymy: The validity of SPITERI’s subspecies bostici and saslowi has been questioned by KLUGE 1993. Lichanura trivirgata arizonae is not listed by CROTHER 2000, nor by WOOD et al. 2008. We consider them as synonyms of L. trivirgata. Illustrations: see several variants as high-res images in LAITA 2013. Subspecies: Based on mtDNA data, WOOD et al. (2008) separated L. orcutti (including L. simplex as a synonym) as an evolutionary species from L. trivirgata (which included L. roseofusca and myriolepis as synonyms). However, they did not provide a diagnosis of this species. These author do not discuss/analyze arizonae, and mention saslowi only once and gracia a few times. These authors do not recognize gracia, roseofusca, myriolepis, and saslowi and therefore relegate them to the synonymy of L. trivirgata (although the authors of this paper do not explicitly address this issue). Klauber (1931) noted that L. t. gracia and L. t. roseofusca ‘‘are virtually indistinguishable in scale counts”, but based the diagnosis on the color and pattern of the dorsal and lateral stripes. Phylogenetic analyses indicate that L. t. gracia populations in California (within Lineage A) are actually more closely related to L. t. roseofusca than they are to their subspecific counterparts in Arizona (=Lineage B), which makes this subspecies paraphyletic (non-exclusive) as currently described [from WOOD et al. 2008]. Distribution: see maps in Yingling 1982, Heimes 2016, Wood et al. 2008. Type species: Lichanura trivirgata COPE 1861: 304 is the type species of the genus Lichanura COPE 1861. |
Etymology | The specific name trivirgata is Latin, meaning three-striped. L. roseofusca was named after Latin roseus = ruddy, and fuscus = dusky. L. r. gracia was named after Latin gracilis = gentle. The genus name Lichanura is derived from two Greek words, lichanos, the forefinger, and oura, tail; this may be an allusion to the body form of this snake. |
