Making the most of your host: the Metrosideros-feeding psyllids (Hemiptera, Psylloidea) of the Hawaiian Islands Author Percy, Diana M. text ZooKeys 2017 649 1 163 http://dx.doi.org/10.3897/zookeys.649.10213 journal article http://dx.doi.org/10.3897/zookeys.649.10213 1313-2970-649-1 5615ED7CAF3E41B69963F6458804186D 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.
