If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
K. E. Campbell 1976Tarsometatarsus differs from that of Butorides virescens, B. striatus, and B. sundevalli by having (1) intercotylar prominence more rounded proximally, more robust, and less clearly demarcated posteriorly; (2) anterior lip of internal cotyla deeply undercut in
medial view (prominent ridge extending distad present in B. virescens, B. striatus, and B. sundevalli); (3) inner calcaneal ridge of hypotarsus very short and curved (long to moderate length in B. virescens and B. striatus, long in the one B. sundevalli available;
slightly curved in all) ; (4) ridge leading distad from inner calcaneal ridge of hypotarsus long and slightly curved in medial view (short and sharply curved in B. virescens, B. striatus, and B. sundevalli); (5) proximal foramina and tubercle for tibialus anticus
located slightly more proximad; (6) shaft very broad for entire length (narrows sharply immediately distal to cotylae in B. virescens and B. striatus; narrows similarly in B. sundevalli, but shaft broader than in previous two species); (7) edge of shaft straight internal to tubercle for tibialus anticus (locally curved in B. virescens and B. striatus; curvature present and less localized in B. sundevalli); (8) curvature of shaft in anterior view less pronounced; (9) intertrochlear grooves similar to those of B. virescens and B. striatus (larger in B. sundevalli); (10) trochlear surfaces wide (narrower in B. virescens and B. striatus; wide in B. sundevalli); (11) external trochlea extend farther distad; (12) depression in lateral surface of external trochlea deep and restricted (shallow in B. virescens and B. striatus, of moderate depth in B. sundevalli; restricted in all). The internal trochea of the holotype tarsometatarsus of B. validipes has the distal end missing.
