Note: Pythonissa nana is a nomen dubium and
most authors list it as an unidentifiable
species of Gnaphosa. However, the description
by Koch
(1843) describes a small black spider with a
white-marked opisthosoma, quite unlike any
species of Gnaphosa. The spotted opisthosoma
points to a species of either Aphantaulax,
Poecilochroa, Kishidaia or Callilepis. Koch
himself compares his new species with
Kishidaia conspicua, suggesting that the two
are related. However, the leg color pattern
given in the description does not agree with
Kishidaia or Poecilochroa (see also the next
note!). Also the small size of Pythonissa nana
of below 4 mm argues against Kishidaia and
Poecilochroa. Aphantaulax has never been
recorded from Germany, thus is unlikely as
well. Species of Callilepis are frequently
below 4 mm and especially as juveniles show
the leg color pattern and very weak white
spotted opisthosomal pattern described by
Koch. Thus, I suggest that the single dried
out specimen available to Koch that was the
basis for the species description of
Pythonissa nana was a juvenile Callilepis
nocturna.
Note: the coloring of Pythonissa nana in Koch´s
(1843) book on plate CCCLVI is incorrect and
does not agree with the text. This is a common
problem with older works that have colorized
copper (or other) plates. Mostly the author
had an opportunity to proofread the typeset
text and the original engravings for the
plates prepared by illustrators/engravers. But
then all copies of the book were painted by
colorists without the control of the author.
Often the colorists demonstrated quite some
creativity and thus many copies of the same
work show very different colors for the
species. In the copies of Koch´s book
that I have seen so far, the painting of
Pythonissa nana is wrong, probably because the
text is confusing on first reading: "Die
Taster, die Hüften, die Knie, die
Schienbeine und die Fersen der Beine sind
hellgelb, die Schenkel und die Scheinbeine der
letztern glänzend schwarz." The confusion
arises from the double meaning of the German
"letztern" (1: "the latter"; 2: "the last").
The true meaning is only obvious if one
realizes that the color of the tibiae has
already been defined as "yellow" and thus
"letztern" does not refer to all legs, but
only to the "last" legs. The correct
translation is therefore: "The pedipalps, the
coxae, the patellae, the tibiae and the
metatarsi of the legs are light yellow, the
femora (of all legs) and the tibiae of the
last legs (=hind legs) are shining black".
This pattern is virtually identical with the
leg color pattern of juvenile Callilepis.
