Tiporus undecimmaculatus (Clark, 1862)

Type material studied. Syntypes, 2 females: “ Paralectotype ” [printed, round and blue bordered label], “ New Holland ” [handwritten, round], “ H. maculatus Clark ” [yellow, handwritten], “ Hypodes undecimmaculatus Clk ” det. C. Watts 1974” [handwritten, printed] (NHM) .

An additional historical specimen, most probably from Clark´s collection, was also studied. Male: “Lectotype” [printed, round and violet bordered label], “67.56”, “ H. maculatus Clark ” [yellow, handwritten], “Hypodes undecimmaculatus Clk ” det. C. Watts 1974” [handwritten and printed white label] (NHM).

Remarks. According to the original description by Clark (1862: 412) the species was described after two specimens from “ New Holland ”. Therefore the designation of third specimen as a lectotype is invalid. We do not consider the designation of a lectotype necessary, as this would not serve in any way the stability of the nomenclature. Both syntypes together constitute the name-bearing type of Hydroporus undecimmaculatus Clark, 1862 .
