Acrobeloides enoploides A..L O O F 1971, n.sp.

Acrobeloides enoploides n.sp.

(Fig. 1, D-I).

Dimensions:

Females (n = 21): L = 0.38 mm (0.34-0.43); a = 16 (14-19); b = 3.4 (3. 1- 3.6); c = 19 (17 - 21); V = 66 (64 - 68); G prevulvar = 13 (7 - 17); G postvulvar = 13 (7 -16); T/ABW = 1.5 (1.4-1.7).

Female, holotype: L = 0.40 mm; a = 15; b = 3.4; c = 18; V = 1 06514; T/ABW = 1.6.

Male not found.

Body stout, fusiform. Transverse striation of cuticle distinct, measuring nearly 2 \L on mid-body. Lateral field with two inconspicuous wings (three longitudinal grooves). Prelabial probolae with slightly drawn out, acute tip; somewhat indented halfway. No distinct labial probolae. Corpus of oesophagus fusiform. Excretory pore and hemizonid opposite or slightly behind junction of corpus and isthmus; excretory gland opposite junction of isthmus and bulbus. Vulva lips protruding in some specimens, hardly so in others; this may be connected with the age of the individual. Gonad cephaloboid, ovary with double flexure behind the vulva. Rudiment of second gonad extremely short. Tail very plump, very broadly rounded, tip often slightly oblique; with nine to twelve annules. Immediately before and behind the anus there is usually an annule twice as long as the others. Phasmids opening just before the middle of the tail.

Holotype: Female on slide WT 1197. Paratypes: 20 females on slides WT 1198 - 1211.

Type locality and habitat: Sample 3. Paratypes from samples 3, 20, 24, 25, 26, 48 and 64. Found furthermore in samples 21, 23, 30, 38, 40 and 43.

This species resembles A.enoplus Steiner, 1938, from which it differs by the much plumper tail and the faint indention in the - somewhat Chiloplacus-like - prelabial probolae.
