Morebilus fumosus |
(identification based on a paper by Norman Platnick; see notes below)
female: 15 mm|
male: 11 mm
Under loose bark in eucalypt forests
Uncertain; may be aggressive when defending its egg sac
The front parts of this spider are typically reddish brown in colour but the abdomen and
chelicerae may be charcoal grey or black. The body is flattened and the legs curve forward in a fashion somewhat
similar to that seen among huntsman species. The spinnerets are too short to be seen
from above, unlike Hemicloea species (Family Gnaphosideae) which otherwise are reasonably similar in overall appearance.
Note that Hemicloea species can be seen to have three pairs of finger-like spinnerets when viewed from underneath whereas those members of the Family Trochanteriidae
that resemble Hemicloea have two very short pairs of spinnerets and a central pair of parallel rows of silk-secreting spigots. In addition, the
outer segments of the first two pairs of legs on the trochanteriids such as Morebilus fumosus have visible spines whereas the legs of Hemicloea species only have
some fine hairs.
It is very difficult to distinguish between Morebilus and the less common Rebilus and it is for this reason an image included on this page is shown as a possible Rebilus lugubris photo.
Spider(s) with a very similar appearance: Some other trochanteriids and also Hemicloea rogenhoferi.
