Abstract
Two new species of the previously monotypic genus Eulophophyllum Hebard, 1922 are described. All species of the genus known up until now occur in forested areas in Sabah, Borneo. The genus is unique for the strongly widened media field of the tegmen, in which all branches of the media anterior plus radius sector are strongly curved and run anteriorally. There is also a striking color difference between the sexes, with males uniformly green and females pink. The two new species Eulophophyllum lobulatum Ingrisch & Riede sp. n. and Eulophophyllum kirki Ingrisch & Riede sp. n. have large leaf-like expansions of the hind tibiae that are absent in E. thaumasium Hebard, 1922. They differ from each other in the number of main vein branches in the media field of the tegmen. Stridulation of E. lobulatum sp. n. consists of short double-clicks ranging from 6.5 to 8.5 kHz, repeated at longer intervals.
Keywords: crypsis, tegminal venation, stridulation
