EUSCHONGASTIA FROM BORNEO 
81 
is 9^, not 13-15 as in rolnis. Scutum produced into “shoulders’ 7 at insertion of AL setae 
instead of being merely rounded. Posterior margin of scutum more sinuate than in roluis 
(cf. fig. 11). Scutum with rather pronounced ridges posterior to sensillae bases; these absent 
in roluis. 
Description of Larva. — Body: Subovate, about 364x225^ in somewhat engorged holotype. Eyes 
distinct 2+2 on ocular plate, anteriormost somewhat the larger; posterior eye in a line with PL. 
Gnathosome: Chelicers and lateral tooth as in preceding species. Palpal formula b/b/bbb, each seta slightly 
variable regarding degree of fraying, but with only one or two branches. Palpal claw with medial prong 
longest, lateral prong one-half to two-thirds as long, middle prong intermediate. Scutum: Fairly large; 
seven-eighths as long as broad; anterior margin somewhat sinuate, the convexity median; posterior margin 
more sinuate, the medial portion concave; with “shoulders” at PL, but remainder of lateral margins 
slightly convex. AM seta about half length of scutum. AL setae displaced caudad to a level midway 
between SB and anterior margin of scutum; less than one-third length of scutum. PL setae nearly 
three-fifths length of scutum. All scutal setae with barbs inapparent, short. Body Setae: Dorsal setae 
similar to scutal setae, about 24-26 arranged typically 2. 6. 6.4.4. 2. Ventral setae about 12,19^ long, plus 
10-12 postanals. Legs: essentially as in E. indicella n. sp., including sensory setae.

Type Material. — Holotype and two paratypes on Chiropodomys legatus, Mt. Kinabalu, Tenompok, 
elev. 4,500 ft., viii. 1951 ( R . Traub). Holotype (U.S.N.M. 2113) in U.S. National Museum. Others in 
authors’ collections. 
Euschongastia daria n. sp. (figs. 25-30 and 33-35, p. 83). 
Diagnosis of Larva. — Close to E. audyi Womersley, 1952, but separable as follows: With 
only one pair of sternal setae between coxae III ; not two. Tarsus III with but one mastitarsala 
(fig. 29) instead of two, one of which is ventral (cf. fig. 32, E. audyi). Tibia III bearing only 
one sensory seta (fig. 29) lacking the two subflagellate setae of E. audyi (fig. 32). Leg setae 
relatively stout, freely branched, subpectinate at base (fig. 33); in E. audyi these setae are fine, 
long, and with short inconspicuous branches (fig. 31). 
Description of Larva. — Body: Subovate, about 355 x 255(1 in rather engorged holotype. Eyes 2+2 on 
ocular plate, fairly close to base of PL; anterior eye somewhat the larger. Gnathosome : Chelicers about 
four times as long as broad at base; with tricuspid cap of genus. Palpal formula B/b/Nbb. Palpal claw 
2-pronged, medial prong the longer and stouter. Maxillary seta fairly plumose. Scutum: Almost as 
long as broad at level of sensillary bases. Somewhat rectangular but caudal margin rather convex; 
anterior margin slightly sinuate; lateral margins shallowly concave. AL setae somewhat displaced caudad, 
but much closer to anterior margin than to sensillary ridges. With ‘ shoulders ’ at PL bases. Sensillary 
bases at midline of scutum. Scutal setae with short barbs; AL about 1/2 length of scutum; AM about 
2 1 3~3 1 4 length of dorsal plate; PL slightly longer than AM. Body Setae: Dorsal setae similar to scutal

setae; about 24-26 usually arranged 2.6.64.4.2. Ventral setae about 16, 2 X|jl long, lightly plumed plus 
about 12 postanal (caudal) setae. Legs: Non-sensory setae all subpectinate or with distinct branches, but 
with a definite tendency for distal third to be simple and slender. Sensory setae as follows: Legs I and II 
as in E. indicella n. sp. Leg III with the usual single genuala and tibiala but in addition with a long 
mastitarsala. 
Type Material. — Holotype from a chick of an unidentified ground bird, Mt. Kinabalu, Tenompok, 
elev. 4,500 ft., 28. vii. 1951 ( R . Traub). Paratypes from same locality as follows: 4 ex Tupaia montana 
baluensis, a tree shrew, 16 & 17, vii. ( R . Traub & J. R. Audy ), 1 ex Tupaia m. minor , 3. viii. ibid ; 2 ex 
Nannosciurus whiteheadi , loc. cit. I7vii ( R . Traub and J. R. Audy ); and one ex Rattus whiteheadi , ibid but 
23. vii. Holotype (U.S.N.M. 2114) in U.S. National Museum, paratypes in U.S.N.M. and authors’ 
collections.
