(Raven, 1979), and a barychelid, Troglothele caeca Fage from Cuba 
(Fage, 1929). Since then Gertsch (1971; 1973; 1982) has recorded 10 
additional species of blind or near blind cavernicolous mygalo- 
morphs from the Americas. This brings to about 8 the total of 
known blind, and an additional five or more near blind cave- 
adapted mygalomorphs in the world. 
Affinities of Troglodiplura lowryi with other Australian 
Diplurinae 
At the time Troglodiplura was described the Australian Dipluri- 
nae included six other genera: Aname Koch, Ixamatus Simon, Che- 
nistonia Hogg, Dekana Hogg, Sungenia Rainbow & Pulleine and 
Stanwellia Rainbow & Pulleine. One species had also been attrib- 
uted to the extra-limital genus Brachythele (Ausserer, 1875). Subse- 
quent descriptions of new genera, and reviews of the Diplurinae 
(Main and Mascord, 1971; Main, 1972; 1975; 1983b; Raven, 1981; 
1984) bring the total of accepted genera to eleven: Aname, Ixama- 
tus, Chenistonia [synonymised with Aname (Raven, 1981; 1984) but 
recognized as distinct by Main (1982a, b, 1983b and here)], Stanwel- 
lia, Troglodiplura Main, Kiama Main and Mascord [doubtful 
placement in the Diplurinae (Main, 1981, p. 869)], Teyl Main, Xami- 
atus Raven, Kwonkan Main, Merredinia Main and Namea Raven. 
However, the affinities of Troglodiplura have remained unclear. It is 
now apparent that one character is shared with several other genera. 
This is the absence of cuspules from the maxillary heel (see Main, 
1969, fig. ID, and figs 1,3, 5, 6 here). This arrangement is character- 
istic of the following genera: Ixamatus and Xamiatus (Raven, 1981), 
Kiama (Main and Mascord, 1971, see fig. 2) and in part Stanwellia. 
Genera constituting the Anamini as delimited by Main (1983b) and 
the Teylini which contains the nominal genus Teyl (see Main, 
1982c) and several undescribed genera (Main, 1983b) and Namea 
(herein included) all have the cuspules spread over the inner side of 
the maxillae including the modified, projecting heel. [The only 
exception in these groups is Aname kirrama Raven (Raven, 1984) 
which has the maxillary cuspules confined to the anterior ental 
region]. On this character then Troglodiplura has an affinity with 
Ixamatus, Xamiatus, Kiama and in part Stanwellia. Closer affinity 
with Ixamatus and Xamiatus is ruled out primarily due to the low 
tarsal organ in Troglodiplura (that is, not rod-like); with Stanwellia
