Etheostoma sellare Radcliffe & Welsh, 1913 (1912?)
Taxonomy & Nomenclature
Synonym/s: Hadropterus sellaris Radcliffe & Welsh, 1913 (original combination); Poeclichthys sellaris Radcliffe & Welsh, 1913
Last record: 1988 (Suckling et al. 2004)
IUCN RedList status: Extinct
The Maryland Darter (Etheostoma sellare) was originally described based upon two specimens*, both sub-adult males, collected in 1912 and described as coming from "Swan Creek, near Havre de Grace, Md.," (the type locality). However, subsequent attempts to collect the species failed until 1962 when Cornell University students serendipitously discovered a juvenile individual amongst a group of Tesselated darters which they had collected earlier (U.S. Fish and Wildlife Service, 1985). The first live specimen collected from the wild was in 1965 (Ibid.). Numerous specimens were collected and preserved between 1962 and 1971, and the species continued to be captured and released until 1988 when the final reports of this species were made (Ibid.). A renewed effort was made to locate the species in 2009 (The BayNet.com, 2009), however it unfortunately met with no success. Hern (2011) reported a similar failure.
* Neely et al. (2003) commit two factual errors when they state that the species was described based on a single specimen collected in 1911. A reading of the original paper (available online) clearly mentions two specimens captured on May 2, 1912 and not 1911 as (Ibid.) state.
Biology & Ecology
Holotype: USNM 74346 (sub-adult male)
Type locality: "Swan Creek, near Havre de Grace, Md.,"
According to (U.S. Fish and Wildlife Service, 1985) 80 specimens are preserved in museum collections, and none of these dates to after 1971. However that publication was published in 1985 and yet the Maryland Darter was last seen in 1988. So it is possible that other specimens were preserved in the final years of the species' existence (one specimen was collected in 1985: https://www.floridamuseum.ufl.edu/100years/maryland-darter/).
