Kamimuria brunneicornis

Kamimuria brunneicornis (Klapálek, 1921) (Fig. 1) Marthamea brunneicornis Klapálek, 1921: 147. Kamimuria brunneicornis: Wu, 1938: 62; Claassen, 1940: 125; Illies, 1966: 265; Sivec et al., 1988: 32; Du et al., 1999: 60; Sivec & Stark, 2008: 137; Stark & Sivec, 2013: 117. Kamimuria jeanneli Wu, 1935: 229. syn. nov.; Claassen, 1940: 122; Illies, 1966: 478; Du et al., 1999: 61; Sivec & Stark, 2008: 137; Stark & Sivec, 2013: 117; Huo et al., 2022: 282. Kamimuria robusta Wu, 1948: 268. syn. nov.; Li et al. 2020: 371. Examined material. Kamimuria robusta Wu, 1948: 1 male (IZCAS), labelled “ neotype, Fujian, Shaowu, Lijiapo (the same village as Li-Chia-p’o in Wu 1948), 1944.II.16,” leg. unknown (Fig. 1). Remarks. Kamimuria robusta Wu, 1948 was redescribed recently based on both sexes, but the neotype was not designated because the body color and emerging date are quite different from holotype (Li et al. 2020). This male bears the same collecting site and date as for holotype, but the “ neotype label” shows that it is not the holotype; this neotype designation was never published; however, it is formally designated herein because the holotype was lost (Wu 1962). Additionally, the neotype shows identical characters with the recently found specimens (Li et al. 2020), although the holotype is said to have brownish body color, the neotype designated here and the specimens recently reported by Li et al. (2020) have a darker habitus, hence such differences herein can be considered as intraspecific individual variations. In several southeastern provinces of China there may occur multiple species of Kamimuria with brown or blackish body coloration, i.e. Kamimuria brunneicornis, K. circumspina Li, Mo & Yang, 2019, K. jeanneli, K. robusta, K. simplex and K. tienmushanensis. Among these species, K. brunneicornis and K. jeanneli are known only from female holotypes. Fortunately, the females of these six species have been described (Chu 1929; Huo et al. 2022; Klapálek 1921; Li et al. 2019, 2020; Wu 1935). The subgenital plates of these females all have a notched apex except for K. jeanneli Wu, 1935 and K. brunneicornis. However, the description of the female of K. robusta by Li et al. (2020) clearly demonstrated that it indeed has a unnotched subgenital plate. Dark Kamimuria species were rarely found in Kamimuria in the southeastern provinces of China (Huo et al. 2022), however, at that time the identity and color variation of K. robusta were not confirmed with certainty, thus it was not compared with these two species. Herein, we take this opportunity to place K. robusta Wu, 1948 and K. jeanneli Wu, 1935 as junior synonyms for K. brunneicornis. Distribution. Fujian, Jiangxi, Zhejiang provinces of southeastern China.
