Santa Rita Mts, Arizona.
Apart from L. stricklandi (which see), closest to L. villosus, L. borealis and L. albolarvatus, and all previously placed in Picoides. Recent trend to treat present species as separate from L. stricklandi followed here, given its creamy mid-brown vs dark brown mantle, back, rump and wings (2); uniform, unmarked mantle, back and rump vs bold white-barred and brown pattern (3); broad spots on underparts rather than streaks (2); central rectrices with rusty wash (increasingly strong towards tips) (ns); longer bill (effect size of smaller fraterculus vs stricklandi 3.18, score 2). Birds from SE Sinaloa E to W Zacatecas and S to S Jalisco separated as race websteri, but apparently only an intermediate form between arizonae and fraterculus. Two subspecies recognized.
