Diacamma rugosum rugosum Sm. var. ovalis Karawajew, 1935a: 62 , w (unavailable name; first available use of name: Chapman & Capco 1951: 56).

Current status: Diacamma rugosum ovale (s/f Ponerinae ).

Type locality(-ies): “Ba-Me-Thuot, 700 m, Prov. Danlac, Şdannam, an der Grenze von Cambodge, K. Davydov, Nr. 5920, 1 w” .

Original Karawajew labels: 1 w, “Ba Me Thuot / Annam. 30.VI. / 30 K. Davydov ”, “5720. Coll. Karavaievi ”, “ Diacamma / rugosum var. / ovalis Karav. / typus”, “ Holotypus / Diacamma rugosum / v. ovalis Karaw. ”, “Dlussky / restaur.”, “not a type! / 1994 / W. L. Brown ” .

Material: HOLOTYPE, w ( CASENT0916813 ) (Box 2).

Notes. In the early 1990s, we sent a sample of Diacamma type material to Prof. W. L. Brown ( USA) for study, but he was unable to complete a revision of the genus before his death. However, there is an additional Brown label on the pin with this subspecies “not a type! / 1994 / W. L. Brown”. Moreover, the number of the holotype specimen in the original description is 5920, but 5720 in the collection. The situation may be similar to that involving D. rugosum gibbosum (above).
