Xorides ephialtoides (Kriechbaumer, 1882)

Material. Type. Germany: Lectotype ♀ of Xylonomus ephialtoides (designated by Townes, 1964), Frankf. a/M u. Passau; Austria: syntype (“cotype”) of Macrosterotrichus ephialtoides, Austr. Inf., Prater , l.05.1911, 1 Ơ ( Wachtl ) ( ZSSM). Non-type. Ukraine: Kyiv, Bilychi , 15.06.2010, 3 ♀; 28.06.2010, 1 Ơ (M. Zaika) ( SIZK).

D i s t r i b u t i o n. Palaearctic; Ukraine ( Varga, 2015 b).

Remark. This species was recorded by Kasparyan (1981) from the Kharkiv and Kherson Regions of Ukraine. No additional material was found, and the species was included in the Ukrainian catalog of Varga (2015 b) based only on literature data. The paper also included another species, Xorides rusticus (Desvignes, 1856) , identified on the basis of a female (partially damaged) collected in Kyiv. After examining the type specimens of X. ephialtoides and X. rusticus , the first author found that the Ukrainian female of X. rusticus differs from both species in that the first metasomal tergite is elongate (more robust in X. ephialtoides ), with well developed carinae (not developed in X. rusticus ). Furthermore, the black coloration of the hind trochanter, trochantellus, and partially of the femur in combination with the well developed carina of the first tergite suggest that the Ukrainian specimen may represent an unknown female of X. ilignus Hilszczański, 2000 , but we currently refrain from describing it until male and female are collected or reared from the same locality. Therefore, X. rusticus should be excluded from the Ukrainian list of the subfamily Xoridinae .
