PARATYPES
: None.
DIAGNOSIS: Configuration of the antennomeres distinguishes specimens of this species from superficially similar specimens of
P. sericellopsis
; in
P. insula
beetles, antennomere eight is abruptly narrowed distally, whereas in
P. sericellopsis
specimens antennomere eight narrows gradually.
DESCRIPTION:
Size
: Length: 5.1 mm; width 2.0 mm.
Integument
: Cranium predominantly castaneous, frons and vertex narrowly piceous; pronotum castaneous; elytra variegated, humerus flavotestaceous, pale setae arranged into three irregular fascia; legs bicolorous, predominantly flavotestaceous, femora and tibiae infuscated.
Head
: Antennal club as in figure 167.
Thorax
: Pronotal anterior margin moderately projected at middle; pronotal disc with two prominent swellings; elytral epipleural margin with six conspicuous trichobothria; protibia anterior margin with three spines.
Abdomen
: Female pygidium broad scutiform.
VARIATION: Not observed.
NATURAL HISTORY: The available specimen was collected from the
type
locality during June, ‘‘on dead twig’’.
ETYMOLOGY: The trivial name
insula
is a Latin noun meaning ‘‘island’’. I refer to the
type
locality.
