|---|---|---|
| D. P. Plax et al. 2018 | Stylonurid of medium size, 12–34 cm in length.
Prosoma is horseshoe-shaped with a relatively narrow marginal rim. Compound lateral eyes are crescentic, located in the anterior half of the prosoma. Opisthosoma is wide, the metasoma bearing slight epimera, and tapering into a styliform telson. Prosomal appendages are robust, gradually increasing in length anteriorly to posteriorly. Prosomal appendages II − IV are spiniferous Ctenopterus-type; prosomal appendages V and VI are nonspiniferous Parastylonurus-type. The metastoma is petaloid in shape, markedly narrower than long with an angular anterior notch and a flattened posterior margin. Type A genital appendage is long, reaching beyond the fifth opisthosomal segment, and is composed of at least two segments with a median ridge. Type B genital appendage is short and narrow. The pretelson is elongated and bears a pair of ridges ventrally comprised of large overlapping scales. Cuticular ornament is in the form of small, contiguous or separate, semilunate, linguoid-shaped and acicular scales, which in some places transform into ridges and crests. |
