Hyorrhynchus birmanus Eggers (Figs 5–6) Hyorrhynchus birmanus Eggers, 1939a: 1 . Thai distribution: N: Mae Hong Son ( Beaver & Gebhardt 2004 ), Chiang Mai . New records: Chiang Mai , Doi Inthanon NP , summit marsh, 18° 35.361' N , 98° 29.157' E , 2500 m , MT , 2–8.vii., 6–13.ix.2006 ( Y. Areeluck ) (4) ; as previous except: checkpoint 2, 18° 31.559' N , 98° 29.941' E , 1700 m , 22.vii–2.viii.2006 (1). Other distribution: Myanmar . (2) Taxonomy: As noted by Beaver and Gebhardt (2004) , Hyorrhynchus tuberopectus Huang & Yin is likely to be a synonym, but type material of that species is not currently available for examination. Biology: Not described. The gallery system is probably similar to that of Pseudohyorrhynchus wadai Murayama ( Beaver & Gebhardt 2004 ) , with a radial gallery leading to longitudinal branches up and down the stem in which the larvae feed on ambrosia fungus growing on the walls.
