Dieuches jacobsoni Breddin, 1906: 329 View in CoL . Syntype (s): ♀, Java: Samarang; depository not stated.

Current status. Metochus jacobsoni View in CoL (combination proposed tentatively by Eyles 1973: 37).

Type material examined. Lectotype (present designation): ♀, “Java, Sama- / rang, 33M / lg. Jacobson” [hw], “Museum Leiden. [pr] / Dieuches [hw] / jacobsoni Bredd [hw] / det: [pr] Blöte [hw]” [with black frame]; pinned, segments II–IV of both antennae, right fore leg, tarsi of left fore, mid and hind legs, tibiae and tarsi of left mid and hind legs lacking ( RMNH) ( Figs. 23–25 View FIGURES 20 – 25 ).

Remarks. Being unable to locate any type specimens, Eyles (1973) inferred from the original description that Dieuches jacobsoni , D. nudipes , D. schultheissi and D. villosulus probably belong to the genus Metochus . Examination of the hereby designated lectotypes and paralectotypes led us to the same conclusion for all four species. Similarly, D. kreyenbergi Breddin, 1906 and D. procericornis Breddin, 1908 ( lectotypes of these were already designated by Gaedike (1971)) represent valid species, both belonging to Metochus ( Scudder 1962) . All of the above species are valid. A revision of the genus is in preparation by the senior author; the identity of the widely distributed and often mentioned M. uniguttatus (Thunberg, 1822) was recently clarified by Kondorosy et al. (2014).
