Parapronematus formosanus Tseng, 1985

Parapronematus formosanus Tseng, 1985: 85 .

The description of this species is detailed, missing few measurements, although information on variability was not provided. The illustrations are detailed, though without scale bars. Striae are shown on dorsum and venter of the idiosoma. The ventral setae are illustrated in detail,

varying from the very broad and leaflike pt to the lanceolate mtβ.

Calls attention the statement “legs strongly sclerotized, brown in colour”. As far as we know no other sclerotised species have been reported in Iolinidae . Two inconsistencies were detected between the descriptive text and the illustrations: in the differential diagnosis with P.

acaciae, femora III and IV are mentioned to have two pairs of setae each. We suppose that this should refer to femora I and II, as described in the table with the number of setae on the legs and the depicted number of setae in the illustrations. Secondly, the text mentions the presence of striae in a diamond pattern anteriad ag1, which seems to be correct, while the pattern is illustrated in Figure 130 anteriad mtβ.

As distinguishing characteristics, we retain: setae ro, ex, c1, c2, d1 and e1 stout and lanceolate, other dorsal setae on opisthosoma long, thin and pointed; eupathidia of intermediate length (tc″ /tarsus I≈2.2); two setae on each of femora I and II (instead of the usual three); tarsi

III and IV each with five setae; setae pt, mtα and mtβ barbed, from leaflike to lanceolate.
