Figures 47-50 Arrenurus (Micruracarus) anbangbang sp. nov., holotype 6 (unless stated otherwise): 47, ventral view; 
48, dorsal view; 49, palp; 50, ventral view, paratype 9. Scale lines, 50 pm (Figure 49), 200 pm (Figures 
47-48, 50). 
posteriorly and laterally widened (Figure 50). 
However, there is much variation in the shape of 
the genital plates, many females have more bowed 
genital plates, which are narrowed laterally. 
Lengths of PI-PV: 29, 58, 41, 84, 41; PII with three 
setae on medial side, palp as in male. Lengths of I- 
leg-4-6: 136, 116, 121. Lengths of IV-leg-4-6: 175, 
145, 131. 
Remarks 
The new species is close to A. forpicatoides 
Lundblad. The male of the new species has a free 
lying petiole, while the petiole of A. forpicatoides is 
fused with the cauda by a hyaline area. According 
to Lundblad (1947) A. forpicatoides has no petiole, 
but instead a hyaline area, which he supposed to 
be homologous with a petiole. However, in my 
opinion a distinct petiole is present in forpicatoides, 
which is, as stated above, fused with the cauda. 
Another character that separates the male of the 
new species from forpicatoides is the shape of the 
caudal lobes (rounded in anbangbang, truncated in 
forpicatoides). The female of the new species is close 
to A. jabiruensis sp. nov., A. madaraszi Daday and 
A. forpicatoides Lundblad. A. anbangbang differs 
from these three species in the large, pronounced 
anteroventral comer of PIV. A. jabiruensis has less 
bowed genital plates, but due to the variation in 
the shape of the genital plates, the differences are 
small. Further, females of jabiruensis have a distinct 
truncated posterior body part. Females of A. 
madaraszi are very close to the new species, but
