Stead of merely punctae. Agreeing with G. (G.) rutila Gater, 1932, 

 and G. (G.) romeri Womersley, 1952 (new combination) in the 

 approximate number of dorsal setae captured by the scutum. Dis- 

 tinguishable from G. romeri as follows : Scutum with scattered small 

 pits in addition to punctae, instead of being merely uniformly punc- 

 tate. Palpal claw 3-pronged, not 2-pronged. Ratio of SD:PW is 

 1.8, not 2.15. PSB less than 131 instead of 157. Separable from 

 G. rutila for the following reasons : Scutum with small pits as well 

 as punctae, instead of merely punctae. PSB more than 116 instead 

 of approximately 100. Ratio SD:PlV=i.% not 1.6. SB more than 

 45 instead of approximately 41. Some of the palpal setae branched 

 instead of being nude. With about 40 dorsal setae, not approximately 

 26. The shape of the scutum immediately separates this species from 

 G. tenella, new species, which also has 6 usurped setae (fig. 37). 



Description of larva. — Body: Subovate, about 424x288 microns 

 when fairly engorged. Eyes double; on ocular plate; anterior eye 

 the larger. Gnathosoma: Chelicerae about four to four and a half 

 times as long as broad at base ; with typical distal tricuspid cap but 

 apex more deeply sclerotized, acuminate. Palpal setal formula 

 B/B/b{N)NN. Scutum: Long (as typical for genus) but relatively 

 quite broad ; less than one and a half times as long as broad ( 150 x 114 

 microns in holotype). Anterior margin slightly concave. Lateral mar- 

 gins oblique to an "angle" caudal to PLs and then shallowly convex. 

 Caudal margin broadly and evenly rounded. With small pits the size 

 of setal bases scattered over surface of scutum, interspersed among 

 micropunctations. AL setae stout, bushy. PL setae resembling ALs 

 but somewhat longer. Number of dorsal setae usurped by scutum 

 varying from 4 to 9 but generally with 6. Of the typical 3 pairs, first 

 pair (PPL-i) inserted somewhat anterior to midline and more medial 

 in position; PPL-s at distal sixth. Usurped setae resembling PLs. 

 With a distinct ridge anterior to sensillary bases; the general area 

 devoid of pits or punctae. Bases of sensillae about as close to imagi- 

 nary line connecting ALs as to level of PLs, but each base in vertical 

 line with each AL, Sensillae clavate; about three times as long as 

 broad (35x11 microns), excluding petiole, PPlV-i is 72 (±9); 

 PPW-2, 47 ( ±6) ; PPP-i, 80 ( ±9) ; PPP-2, 63 ( ±8). Body setae:
