Icteranthidium limbiferum ( Morawitz, 1875) ( Figs 36–44 )

Anthidium limbiferum Morawitz, 1875 : ♀, ♂, 120 (key), 123, ♀, ♂. Type locality: Uzbekistan.

Anthidium limbiferum Morawitz, 1875 : Warncke, 1980: 128, ♀ (key), 141, ♂ (key), 174.

Icteranthidium limbiferum ( Morawitz, 1875) : Michener, 1948: 26; Malysheva, 1986: 796, ♂, figs 3, 6, 9, 12; Özbek & Zanden, 1993: 202; Güler et al., 2014: 261; Nadimi et al., 2014: 422; Murao et al., 2015: 10.

Icteranthidium venustum (Morawitz, 1878) : Wu, 2006: 137, ♀ (key), 141, ♀, redescription, ♂, new description; misidentification, incorrect publication date of species, the correct publication time was 1877.

Diagnosis. The species is similar to I. grohmanni ( Spinola, 1838) , but the female can be distinguished from the latter by following: the frons with a large rounded yellow maculation under the middle ocellus; the mesepisternum with a large triangular yellow maculation; the posterior margin of T2 with a broad triangle median process; the T1 laterally with sparse punctation, interstices reach several puncture diameters. Meanwhile, the male has the mesepisternum with a large triangular yellow maculation; the T1 laterally with sparse punctation, interstices reach several puncture diameters; the T7 rounded laterally.

Material examined. China, Xinjiang: Manas Xian (44º18′N, 86º12′E), 580 m , 1♀, 28.VIII.1959, leg. Afu Tian; Shihezi Shi (44º12′N, 86º00′E), 590 m , 1♂, 25.VIII.1959, leg. Afu Tian; Mosuowan (44º48′N, 86º15′E), 350 m , 1♂, 7.VIII.2016, leg. Zeqing Niu, Qingtao Wu; Ili (43º54′N, 81º18′E), 1♀, 15.VIII.1990 , leg. no information on label; Kelamayi, Xiao Guai Village (45º11′N, 85º18′E), 268 m , 1♀ 2♂, 10.VIII.2016, leg. Chaodong Zhu, Dan Zhang.

Flower association. Chondrilla sp. ( Asteraceae ), Lamiaceae gen. et sp., Tamarix sp. ( Tamaricaceae ) ( Murao et al., 2015), Eryngium campestre L. var. virens Link (Apiaceae) ( Güler et al., 2014).

Distribution. China (Xinjiang), Turkey, Iran, Turkmenistan, Uzbekistan, Kazakhstan, Pakistan, Afghanistan.

Remarks. The male specimens, examined by Wu (2006), lack T7, S5–S8 and genitalia. Wu (2006) misidentified these specimens as Icteranthidium venustum (Morawitz, 1878) , which is not distributed in China actually.
