Definition.
Eupnoi sharing a more recent common ancestor with
Enantiobunus spinulosus
Mello-Leitão 1931
(junior synonym of
Thrasychirus gulosus
Simon 1884
) than

or

Hunt & Cokendolpher 1991
.
Diagnosis.
Enantiobuninae
can be distinguished from other
Phalangioidea
by the presence of lateral bristles or bristle groups at the junction of penile shaft and glans (not a lateral barbed process as in
Ballarrinae
). Many
Enantiobuninae
can also be distinguished by the lack of a mobile junction between basitarsus and distitarsus of each leg (present in
Australiscutum
,
Thrasychirus
).
Description.
Lateral bristle groups or isolated bristles at junction between glans and shaft of penis, usually in anterior and posterior pairs. No lateral processes on glans. Spiracle usually with covering grill of slender, anastomosing spines in one or few rows, arising from anterior margin of spiracle. Pedipalp with well-developed claw; dorsal angle between patella and tibia 180° or more; patella (excluding apophysis if present) usually shorter than tibia (only slightly longer if otherwise); tarsus longer than patella or tibia.
Comments.
The phylogenetic analysis reported on above found both
Enantiobuninae
and
Monoscutinae
as recognised by
Crawford (1992)
nested within
Megalopsalidinae
; the three taxa are therefore united herein as a single subfamily for which the name
Enantiobuninae
Mello-Leitão 1931
takes priority.
