Thyanta immemor Kirkaldy , nomen dubium

Pentatoma inconspicua Dallas, 1851: 250 .

Thyanta inconspicua: Lethierry and Severin, 1893:148 .

Thyanta immemor Kirkaldy, 1909:94 ; Jensen-Haarup, 1928:187-188 (replacement name).

Dallas (1851) described T. inconspicua without giving a type locality. Kirkaldy (1909) transferred the species to Thyanta , and renamed it T. immemor , without commenting on either the name change or the transfer to Thyanta . Jensen-Haarup (1928), evidently unaware of the name change, included T. inconspicua in his key to species, but the couplet is essentially a repeat of Dallas' original description and no locality is given.

Although many of Dallas' type specimens still exist and are housed in the British Museum of Natural History, the type of T. inconspicua was not located. Dallas' original description is fairly detailed and contains several characters which would preclude this from being a species of Thyanta . Dallas described T. inconspicua as having six lines ofbrown punctures on the head and a red spot on the ventral surface of the abdomen. These characters have not been observed in any specimen of Thyanta . This species may be valid, but it is doubtful that it belongs in Thyanta .
