Pariaconus
pullatus (Crawford, 1918)
comb. n.
Trioza pullata
Crawford, 1918: 444
Comments.
No new material was collected during this study. Below is a summary of the description from
Crawford (1918)
who considered this, "an incipient species derived from
Trioza lanaiensis
". Additional specimens are needed to test
Crawford's
hypothesis that it may be a local or seasonal variant of
Trioza laniaensis
.
Adult colour and structure.
Generally body colour dark brown to black, probably the darkest of the
ohialoha
group. Fore wing membrane clear. Male unknown. Differs from
Trioza lanaiensis
in shorter antennae (up to 2
x
head width), and genal processes (subequal to vertex length), and a shorter Rs vein in fore wing.
Immature.
Unknown.
Host plant notes.
Probably
Metrosideros
. Original material was collected partly from
Cyathodes
(
Ericaceae
) and partly from an undesignated plant.
Island.
Lanai.
Distribution notes.
Known from two localities on Lanai:
"Waiopao"
("Waiopaa, west side" in
Zimmerman 1948
) 29 Nov. 1916, and "undesignated, Dec. 1916 and Feb. 1917"
Biology.
Unknown, but it likely makes enclosed galls, and if
Crawford's
hypothesis of parallel divergence to that on Oahu is correct (see comment for
Pariaconus lanaiensis
), then this may be a leaf galler.
Type material.
No type material was found at BPBM.
