Measurements (mm) 
Length, 23.2; pronotum length x width, 6.8 x 8.8; 
tegmen length x width, 7.3 x 3.4; hind wings 
vestigial, hidden under tegmina. 
Remarks 
The other cavernicolous species in 
Neotenmopteryx, namely douglasi ( Princis) (= 
Shawella douglasi Princis), from Jurien Bay, Western 
Australia, is distinctly different from N. wynnei, 
and has reduced eyes, longer tegmina, and a large 
densely setose tergal gland on the first segment 
(Roth 1990: 556). 
Etymology 
The species is dedicated to its collector, Mr 
Richard Wynne, a young speleologist. 
Genus Trogloblattella Mackerras 
Trogloblattella Mackerras, 1967a: 39. 
Remarks 
There is only one species in this monotypic 
genus, namely T. nullarborensis Mackerras, and it is 
found only in Western and South Australia. 
Trogloblattella chapmani Roth was described from 
limestone caves in Sarawak (Roth 1980: 97) but this 
species has been transferred to Neotrogloblattella 
Roth (Roth 1991c: 1017).

Ellipsidion humerale (Tepper): Hebard, 1943:110, PI. 
XII, fig. 10; Princis, 1969: 986 (literature). 
Material Examined 
Australia: Western Australia: Cape Range 
Peninsula: 12 (tegmina and wing on slide 25), 
camp, near 22°15'S, 114°03'E, headtorch, 21 May 
1990, Brooks, CR 90 #135 (WAM). 
Remarks 
The species has also been recorded from 
Northern Territory, and Central and Western 
Australia. The type specimen is a female from 
"Northern Territory of South Australia". Hebard 
suggested that E. laetum Hanitsch, from Burnside, 
Northern Territory may be a variant of humerale. 
There is considerable colour variation in this 
species and Hebard suggested that those from 
Western Australia may represent a more western 
race or species but that a "Detailed consideration 
of large series is necessary to determine which." 1 
have available a large number of specimens from 
different localities and time permitting hope to 
study the variation in colour, size, and genitalia in 
this taxon.
