Papuamyr
gen. n.
Type species.
Papuamyr omhifosga
sp. n.
Etymology.
A blend of Papua and the first syllable of the name of the related genus
Myrmarachne
. To be treated as feminine, as is
Myrmarachne
.
Diagnosis.
Small antlike salticids with somewhat swollen male first legs, vertical and excavated male chelicerae with an ectal spur on the paturon, a round bulb on the palp, and a relatively long RTA. In contrast, the
Ligonipes
group of genera has the bulb of the male palp compressed laterally (
Davies and
Zabka
1989
: figs 7 and 9), while most
Myrmarachne
males have projecting chelicerae and thin first legs. An apparent synapomorphy uniting the two
Papuamyr
species described below is a complex fold in the embolus at the point where it crosses over previous loops before terminating (see black arrows in Figs 70 and 78).
Remarks.
Papuamyr
lacks the morphological diagnostic characters of the
Ligonipedina
and
Myrmarachnina
, but we have not found morphological characters that place it more clearly. The molecular data, however, are clear that
Papuamyr
is within the
Levieina
and a close relative of
Agorioides
(Fig. 1).
