Otostigmus owenii Pocock, 1892

Otostigma owenii Pocock, 1892: 319 . Owen’s Island, Mergui Archipelago, Burma. Otostigmus oweni: Kraepelin, 1903: 116 .

Otostigmus ( O.) oweni: Attems, 1930a: 152 .

Otostigmus ( O.) oweni: Lewis, 1991: 338 , figs. 4–7. Sumatra, Indonesia is of uncertain status. Otostigmus ( O.) oweni: Lewis, 1996: 830 , figs. 24–29.

Remarks. Lewis (1996) redescribed Pocock’s holotype of O. owenii noting that it had 2.5 to 2.66 antennomeres glabrous dorsally rather than three as stated by Pocock. Kraepelin’s (1903) and Attems’ (1930a) statements that the prefemoral corner spine is double are incorrect. Lewis stated that O. owenii was very similar to O. multidens , differing in having 4+4 coxosternal teeth rather than five to ten and the presence of a dorsal spine on the coxopleural process. The specimen is, in fact, much more similar to O. rugulosus in particular to specimens from Rangoon ( Burma) identified as such by Pocock (1891) and described above. Differences are the proportion of antennomeres glabrous: 2.5 to 2.66 as compared to 2 to 2.25 (2.4) in rugulosus and the presence of four spine rows on the ultimate leg prefemur rather than the usual three. I do not consider these differences as sufficient to separate it from O. rugulosus and regard it as a junior synonym of that species.

The specimen recorded from Sumatra by Lewis (1991) runs down to O. glaber (= O. astenus ) in Attems (1930a) if scored as having a dorsal coxopleural spine (it is missing on one side) but the coxosternal tooth plates with 5+5 teeth are unlike those of O. astenus and for the present this specimen is regarded as of uncertain status.

Distribution. Burma.
