Diagnosis.
Both
Pygatyphella
and
Pacifica
occur in New
Guinea
and Pacific islands, and both have LO in
V7
retracted to the anterior half or less; the posterior clear portion of
V7
is frequently arched and underlying muscle impressions can be clearly seen. The two genera are most obviously distinguished by their dorsal colouration,
Pygatyphella
having a pattern resembling bird droppings, where most
Pacifica
species have orange pronotum and dark brown elytra which may be pale margined.
Ballantyne & Lambkin (2009)
distinguished two forms within
Pygatyphella
they named
Pygatyphella
A and B. Subsequently
Pygatyphella
B was described from 5 species as a distinct genus
Pacifica
. The following diagnosis of
Pygatyphella sensu
Ballantyne & Lambkin (2013)
is modified from
Ballantyne & Lambkin (2009)
: Dorsal colouration usually cryptic, very pale brown with dark markings on pronotum, MS, MN and elytral base and apex; pronotum often with angulate convergence along lateral margins, and small depression often present just anterior to posterolateral corner; lacking irregularities at the corners; posterolateral corners may project beyond median posterior margin; at least two interstitial lines usually well–defined; elytral margins convex or parallel-sided; posterior area of
V7
may reach into LO (which is medially emarginated); apex of MPP rounded, pointed, or squarely or obliquely truncate; MPP lacking median dorsal ridge (except in
Pygat
.
karimui
), lacking curved, slightly off-centre posterior ridge on ventral surface of T8; dorsal surface of posterior area of MPP faced with cuticle that is not attached to the ventral surface of
V7
and ends just behind the area of muscle attachment posterior to the LO; the anterior margins of this cuticle are reflexed in
Pygat. peculiaris
; median area of this facing cuticle lacking longitudinal split; T8 anterolateral prolongations lacking ventral projections at their base; aedeagal sheath not subparallel-sided in basal third; aedeagus L/W usually>3; LL/ML not wide; ML sometimes asymmetrical in a horizontal plane only, never with lateral teeth; anterior margin of LL often asymmetrically produced.
