We provisionally retain the position of the genus Elegansovella in the family Urodinychidae on the basis of the following characters: setae h1 long; chelicerae with internal sclerotized node and without mushroom- or flower-shaped sensory organ on fixed digit; corniculi smooth apically. However, all taxa of this family merit revision.

Deraiophorus elegans Canestrini, 1897, by original designation.

Idiosoma oval with vortex. One pair of anterolateral prolongations presented on idiosomal margin. Dorsal and marginal shields fused on anterior part of idiosoma. Dorsal setae tree-like, with a short stem and many long cross-bars. Three or four pairs of long and pilose setae situated close to posterior margin of dorsal shield. Marginal setae long and marginally pilose, situated on long marginal prolongations. Shape of female genital shield oval or scutiform, its surface smooth and situated between coxae II–IV. Male genital shield circular and situated between coxae IV. Ventral setae pilose. Tritosternum with vase-like base, its laciniae divided into three branches. Corniculi smooth, horn-like, internal malae serrate. Setae h1 smooth and longer than other hypostomal setae, h2–h4 serrate, but h4 divided into two or three serrate branches. Pedofossae present, but without separated furrow for tarsi IV. Prestigmatid part of peritreme with five bends. Epistome serrate. Chelicerae with internal sclerotized node, fixed digit longer than movable digit. Movable digit with one or two large central teeth.

This species was collected in Bismarck Archipelago and New Guinea (Hirschmann 1989).

Hirschmann (1973) mentioned D. elegans as the synonym of D. pectinata. Later, he (Hirschmann 1989) separated these two species again based on the shape of the basis of the epistome and the width of the peritreme. In our opinion, these differences are too weak and not sufficient to separate the two species. Furthermore, both species were collected in the same region. Thus, we agree with Hirschmann’s (1973) opinion that D. elegans is the junior synonym of D. pectinata.

This species was found in a forest habitat, in Indonesia (Hiramatsu 1980).

Shape of female genital shield linguli- or scutiform, its surface smooth and situated between coxae II–IV. Male genital shield circular and situated between coxae IV. Ventral setae T-shaped, V-shaped or setiform. Pedofossae present, but without separated furrow for tarsi IV. Prestigmatid part of peritreme with two bends. Tritosternum with vase-like base, its laciniae divided into three branches. Corniculi smooth, horn-like, internal malae gently serrate. Setae h1 smooth and longer than other hypostomal setae, h2 smooth or serrate, h3 serrate, h4 divided into two or three serrate branches. Epistome serrate. Chelicerae with internal sclerotized node, fixed digit longer than movable digit. Movable digit with one or two large central teeth.

Only one Monstrobovella species (M. faceta) is known from the Neotropical region. Monstrobovella faceta has T-shaped dorsal setae whose cross-bar part is bifurcated. These setae are spine-like and smooth in the new species. The setae on the caudal region of the dorsal shield are numerous, very long and marginally serrate in the case of M. faceta, and there are only three short, marginally-serrate setae in the new species. Several long and T-shaped setae are situated posterior to coxae IV on the ventral idiosoma; these setae are missing in the new species. There are some small oval pits on posterocentral part of dorsal shield in the new species, which are missing in M. faceta.
