Two new Penemideopsis 
445 
inedially; bearing 3 pairs of sub-equidistant 
dorsoglandularia; dorsoglandularial setae situated 
close to glandularia; postocularia well anterior to 
anterior-most glandularia of dorsal shield. Ventral 
shield (Figure 2) entire; vgl situated near posterior 
margin of coxa II; all coxal suture lines visible, 
those between I and II, II and III, and III and IV 
posterior-laterally directed, thus forming acute 
angles with mid-line; medial margin of coxa IV 
broad; posterior margin of coxa IV rounded, 
extending past anterior margin of genital field; 
outer coxal margins not protruding; openings of 
leg IV covered by small ventral lobes; capitular bay 
deep and basally rounded, extending far forward 
of ventral shield; excretory pore incorporated into 
ventral shield. Genital field (Figure 6) with 3 pairs 
of small acetabula situated within field. Capitulum 
and chelicera basically as for P. phreatica (Cook 
1986: figure 1611). Pedipalp (Figure 4) not uncate; 
tibia with large ventral projection bearing greatly 
enlarged spatulate seta; all setae acuminate. Legs 
(Figures 5, 6) not modified and without swimming 
setae; with very few serrate setae; claws with 
ventral clawlets. 
Dimensions (pm) 6: dorsal shield 339/268, 
ventral shield 429/305. Pedipalp: trochanter 24, 
femur 45, patella 18, tibia 29, tarsus 31. Leg I: 
trochanter 52, femur 40, patella 35, tibia 40, 
metatarsus 50, tarsus 81. Leg IV: trochanter 64, 
femur 56, patella 43, tibia 60, metatarsus 79, tarsus 
75. 
Remarks 
Despite several visits to the type locality, this 
species has not been recollected, and appears to be 
extremely rare. Davis et al. (1988) report that the 
type locality (site C) is amidst jarrah forest and 
urban development, and that the riparian 
vegetation is patchy. 
Etymology 
The specific epithet refers to the small size of the 
holotype (pusilla Latin, very little).

Holotype 
6, Angove River, north of Two Peoples Bay 
Nature Reserve, Western Australia, Australia, 
34°55'S, 118°09'E, 5 February 1991, S.A. Halse, 
A.W. Storey (WAM 95/773). 
Diagnosis 
Penemideopsis angovensis differs from P. phreatica 
as follows: projections covering openings of leg IV 
not greatly enlarged (Figure 8); capitular bay 
projecting far forward of ventral shield (Figure 8); 
outer coxal margins not protruding (Figure 8); and 
its smaller size (e.g. dorsal shield 344 pm in P. 
angovensis, 395 pm in P. phreatica). It differs from P. 
pusilla by the posterior margin of coxa IV not 
extending past the anterior margin of the genital 
field (Figure 8). It differs from both P. phreatica and 
P. pusilla by the lateral displacement of the 
dorsoglandularia such that the dorsoglandularial 
setae are situated far mesal of the glandularia 
(Figure 7). 
Description 
Male 
Dorsal and ventral shields present. Lateral eyes 
present; medial eye present, but quite small (Figure 
7). Dorsal shield (Figure 7) entire and ovoid, widest 
medially; bearing 3 pairs of sub-equidistant 
dorsoglandularia; dorsoglandularia laterally 
displaced such that dorsoglandularial setae 
situated far mesal of glandularia; postocularia well 
anterior to anterior-most glandularia of dorsal 
shield. Ventral shield (Figure 8) entire; vgl situated 
near posterior margin of coxa II; all coxal suture 
lines visible, those between I and II, II and III, and 
III and IV posterior-laterally directed, thus forming 
acute angles with mid-line; medial margin of coxa 
IV broad, not extending past anterior margin of 
genital field; posterior margin of coxa IV rounded; 
outer coxal margins not protruding; openings of 
leg IV covered by small ventral lobes; capitular bay 
extremely deep and basally V-shaped, extending 
far forward of ventral shield; excretory pore 
incorporated into ventral shield. Genital field 
(Figure 11) with 3 pairs of small acetabula situated 
within field. Capitulum and chelicera basically as 
for P. phreatica (Cook 1986: figure 1611). Pedipalp 
(Figure 9) not uncate; tibia with large ventral 
projection bearing greatly enlarged spatulate seta; 
all setae acuminate. Legs (Figure 10) not modified 
and without swimming setae; without serrate 
setae; claws with ventral clawlets. 
Dimensions (pm) 6: dorsal shield 344/263, 
ventral shield 466/336. Pedipalp: trochanter 26, 
femur 49, patella 20, tibia 26, tarsus 26. Leg I: 
trochanter 54, femur 61, patella 38, tibia 39, 
metatarsus 52, tarsus 69. Leg IV: trochanter 78, 
femur 67, patella 52, tibia 61, metatarsus 78, tarsus 
79. 
Remarks
