Aruattus
gen.n.
Type
species:
Aruattus agostii
sp.n.
ETHYMOLOGY.The generic name consists of two parts: ̒
Aru
̓ deriving from the Aru island group (eastern Indonesia), from which the main series of the type species was collected, and ̒
attus
̓ meaning ̒jumper̓; gender masculine.
DIAGNOSIS.
Aruattus
gen.n.
differs from all the euophryines in having a unique combination of genitalic characters: the tooth situated on the embolar disk (arrowed in Fig. 2), the prominent proximal reservoir of the spermathecae (arrowed in Fig. 5), and the epigynal plate with no median septum and no epigynal pocket (Fig. 4).
DESCRIPTION. As for the
type
species, see below.
COMMENTS.
Aruattus
gen.n.
is a fissidentate genus (Fig. 3) of the small litter-dwelling salticids. Although the genus is an obvious member of the subfamily
Euophryinae
, it is difficult to relate it correctly. Its spermathecae contain the well-developed proximal reservoir (arrowed in Fig. 5; ̒the proximal receiver
a
̓
sensu
Żabka Ɩ1987]), and by this character
Aruattus
gen.n.
is close to other members of the so-called ̒saitine̓ group of genera Ɩsee
Davies & Żabka, 1989
], e.g.
Lycidas
Karsch, 1878
. Yet the male palp of
Aruattus
gen.n.
does not possess the second sclerite of the embolar division called by some authors the conductor (usually subparallel to the embolus), which is common for many ̒saitine̓ species Ɩe.g., Zabka, 1987: figs 60, 62]. Besides, we cannot recollect any other euophryine genus having a tooth situated on the embolar disk (
Figs 1
2). Thus, whereas
Aruattus
gen.n.
should be placed in the
Euophryinae
, its precise position within the subfamily is to be further clarified.
COMPOSITION. Currently, the
type
species only, but there are several additional species awaiting description (kept in the
MHNG
and seen by one of us,
DL
, while sorting out the salticid collections from
SE
Asia retained by this museum).
