diagnosis
Diagnosis. Both Pygatyphella and Pacifica occur in New Guinea and Pacific islands, and both have LO in V 7 retracted to the anterior half or less; the posterior clear portion of V 7 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 V 7 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 T 8; dorsal surface of posterior area of MPP faced with cuticle that is not attached to the ventral surface of V 7 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; T 8 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.
