Dieuches jacobsoni Breddin, 1906

( Figs. 23–24 )

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

Current status. Metochus jacobsoni (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 ).

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).
