O. multidens carens Attems, 1938 , 336. Vietnam.

O. multidens carens: Schileyko, 1995 , 74 (in key). O. multidens carens: Schileyko, 2007 , 93 (in key). O. multidens carens: Tran et al., 2013 , 225 (checklist).

Type material. NHMW. Otostigmus multidens carens Attems 1938 . Coll. Musei Vindobonensis Myriapoda. Inv. No 3800 Vietnam, Pulo Dama “Golf v Siam ” leg C. Dawydoff 29.12.1931. Syntype 1.

Description. (Attems data in parentheses where relevant). Length 43 mm. Antennal articles 22, the basal 2.4 glabrous. Forcipular coxosternal tooth-plates with 8 +8 teeth (6+5). Forcipular trochanteroprefemoral process with two small medial denticles.

Tergites 6 to 20 with complete paramedian sutures, marginate from 8 (14) with very slight lateral groove from 8 and weak median keel from 16 to 19. Ultimate tergite with longitudinal depression occupying posterior 50%.

Sternites with short anterior paramedian sutures from 5 to 18 (9–16) occupying anterior 35% on S12. Sternite of ultimate leg-bearing segment with sides converging posteriorly with posterior margin incurved.

Coxopleural process of moderate length with three apical and one lateral spine. No dorsal spines.

Two tarsal spurs on legs 1–18, one on legs 19 and 20 none on 21 (only the first seven pairs of legs with two tarsal spurs). Legs 1–17 with a tibial spur. The single ultimate leg with prefemoral spines VL 3, VM 2, CS 1 (aussen 2, unterinnen 1, innen 1).

Remarks. Attems (1938) differentiated O. multidens carens from O. m. multidens Haase by the first seven pairs of legs only having two tarsal spurs and the smaller number of spines on the ultimate leg prefemur but the specimen here examined runs down to O. multidens in Attems 1930 key. It has legs 1–19 with two tarsal spurs and also the number of prefemoral spines falls within the range for O. m. multidens .

Otostigmus multidens carens I regard as a junior subjective synonym of O. multidens .
