Leg IV short, not reaching margin of body, coxa subtriangular, as broad as long, third segment longer than other segments, fourth segment short, onefourth to one-third as long as third segmente, very long apical setae, flagelliform
, longer than leg IV itself.
The diagnostic characters of Eremulus are (data summarized from descriptions of species): costulae well developed and visible; rostrum rounded; sensilli flagelliform
, rarely spindle-shaped (exceptionally with small sensillar head); anterior part of notogaster with transverse foveolate band; 10 to 11 pairs of notogastral setae; anal and adanal setae simple; epimeral setae branched (1c often setiform); genital and aggenital setae branched (exceptionally setiform).
23 times as long as the transocular width, thicker than others, gradually thickening distad, basis stalked; II-IV flagelliform
, II slightly incrassate distad, IV apically pointed, subarcuate.

The repeated sections of amino acids in dragline silk, for example, differ from the sequence of amino acids in flagelliform
silk, the superelastic thread used in the spiral section of the web.
In comparison, the capture spiral, produced by the Flagelliform
glands, exhibits a low Young modulus, but is exceptionally extensible.
These fibrils form the outer surface of a spider's composite cribellar capture threads and are supported internally by a pair of larger axial fibers produced by flagelliform
glands and spun from spigots on the posterior spinnerets (Peters 1983, 1984, 1986, 1992; Eberhard 1988; Eberhard and Pereira 1993; Opell 1990, 1993, 1994a-d, 1995, 1996).

Diagnosis: Pale yellow species with 3 pairs of marginal setae on scut; male with only a small central shiny spot on st 2; female with paired spots laterally on tg 2-7; head higher than long, entirely pale yellow; eyes slightly oval with long axis almost vertical; pleural setae and setulae on legs yellow; distiph with long apical filaments and broad curved surs, with posteriorly-directed flagelliform
