Neotullbergia laingi Bagnall, 1936 — Figs. 38-42

Neotullbergia laingi Bagnall, 1936
Figs. 38-42
.

Two specimens, a type and a paratype, were in Bagnall's collection. The type is considerably damaged and only sufficient is visible to determine the validity of the genus. The paratype, although also a poor specimen, was used to draw the figures presented here.

Ants III and IV appear to be fused with the antennal segments related as 8: 10: 24. Ant IV has a small apical sensory knob, four-five sensory rods and numerous simple setae. SO Ant III with four sense rods, two sense clubs behind a cuticular fold and eight guard setae, all disposed as in Figs. 39 and 41. The sense rod shown in Fig. 41 is situated on the opposite side of the segment from the main part of the sensory organ. PAO of about 40 irregular shaped vesicles arranged more or less in four rows in a finely granulate area, clearly demarcated from the surrounding coarser cuticular granules. Pseudocelli impossible to decipher.

The clothing is of sparse simple setae, longer posteriorly. Length 1.0 mm., colour apparently white.

Abd IV dorsally bears two large branched anal spines, langer than the hind claw, on tuberculate papillae; anterior to these are two tuberculated chitinous ridges, the whole with setae disposed as in Fig. 42. The anal spines are four times as long as their papillae and their basal portions are also tuberculated. The branches arise basally, one dorsolateral and one ventral. These structures characterise the genus.
