External and internal morphological characters of <i>Eucolaspis</i> assessed.

<p>(A) <i>Eucolaspis</i> (Coleoptera: Chrysomelidae) (modified from Des Helomore’s drawing of <i>Eucolaspis brunnea</i> (Fabricius)). Scale bar = 1mm. Insets show puncturation on pronotum (top) and elytra (below). Insets are not to scale. Morphometric measurements recorded are labeled: BL- body length (mm); BW- body width (mm); AL- antenna length(mm); EL- eltyra length (mm); EW- elytra width (mm); PL- pronotum length (mm); HPD- puncture density on the head (mm^-2); PPD- puncture density on the pronotum (mm^-2); AEPD- punctures density on anterior half of the elytra (mm^-2); PEPD- punctures density on posterior half of the elytra (mm^-2). (B) Aedeagus from a male <i>Eucolaspis</i> beetle collected on apple at Havelock North, New Zealand: a–aedeagus proper; b–tegmen; c–basal hood; d–ejaculatory sac; e–median ejaculatory duct.
