Diagnosis (adults). Dorsal idiosoma ( Fig. 147). Dorsal shield 565–630 µm long, 335–395 µm wide in females, 480–520 µm long, 280–320 µm wide in males, suboval, with longitudinal sculptural pattern of microgranulation in submarginal region and delicate transverse striation on posteriormost surface, with 30 pairs of setae. Most dorsal setae simple, short, needle-like, subequal in length. Setae j1 and r3 short, thick, spine-like, tip usually obtusely rounded; j1 14–23 µm long.

Ventral idiosoma ( Fig. 148). Presternal platelets absent. Sternal shield wider than long, 98–112 µm long 129–147 µm wide, smooth, with three pairs of short subequal setae. Endopodal platelets II-III completely fused to sternal shield; endopodal platelet III-IV large, anterior margin connected to posterolateral corner of sternal shield. Metasternal platelets absent; metasternal setae st4 and adjacent pores placed on soft integument. Epigynal shield slender, smooth, slightly constricted medially, 28–33 µm wide at narrowest point, 31– 43 µm wide posteriorly. Genital setae and pores situated on soft integument besides the lateral margins of the shield; post-genital sclerites absent. Anal shield wider than long, 75–86 µm long and 109–122 µm wide, anterior margin slightly undulating, posterior margin widely rounded, reticulate, with three subequal circum-anal setae and small anus. Metapodal platelets elongate, narrow, curved. Peritrematal shields wide, smooth; poststigmatic sections short, not reaching beyond coxae IV; peritremes wide, conspicuous. Lateral and opisthogastric integument simply striated, with ten pairs of setae in both sexes.

Gnathosoma . All features normal for genus. Epistome as in Fig. 47.

Legs. Both coxal setae on leg I and posterior coxal seta on leg II modified into flat oval disk-like protuberance. Male femur II with robust and obtuse spur. Chaetotaxy of leg segments as in Table 3.

Remarks. Scarabaspis inexpectatus is a widespread and common species, which is often found in fresh herbivore dung or associated with dung beetles (Scarabaeoidea).
