Figure 17 , map 5, plates 5, 29, table 1

DIAGNOSIS: Distinguished from L. anatoles by male genitalia with aperture of secondary gonopore directed ventrally, absence of a sclerite adjacent to distal edge secondary gonopore, distal region of endosoma with undulate ventral margin (pl. 29A–C), left paramere with rounded apex of anterior process (pl. 29H), and long, substantial distal region of right paramere (pl. 29J), as well as by black on clypeus confined to apex, faintly black antennal segment 1, labium exceeding apex of metacoxa, and longer shorter parempodia (fig. 17D).

DESCRIPTION: MALE: Mean total length 3.88, mean pronotum width 1.22. COLORATION (pl. 5): As in generic description but apex of clypeus black, antennal segment 1 mostly diffusely black, and frons at most tinged with orange. STRUC-

TURE: Labium just exceeding apex of metacoxa. Pretarsus: Parempodia relatively long (fig. 17D). GENITALIA (fig. 17C, pl. 29A–J): Endosoma: Tightly coiled; subapical region between apex and secondary gonopore of dorsal strap with somewhat tumid ventral margin; distal edge of secondary gonopore without process. Secondary gonopore: Aperture ventral. Phallotheca: Apical region with posterior and anterior edges of equal width. Parameres: Left paramere: Apex of anterior process rounded. Right paramere: Apical region long, apex rounded.

FEMALE (pl. 5): Coloration as in male; differing from male as in generic description; mean total length 3.47, mean pronotum width 1.19. GENITALIA (pl. 29K–N): As in generic description.

ETYMOLOGY: Named in honor of Gerasimos Cassis, collector of many of the known specimens.

HOSTS: Recorded from the following species of Myrtaceae : Calytrix angulata (pl. 37E), C. strigosa , Micromyrtus obovata , Verticordia densiflora (pl. 41D), V. picta (Chamelaucieae) , Leptospermum crassipes , L. fastigiatum (pl. 38G), L. sp., and Pericalymma ellipticum (pl. 41A) ( Leptospermeae ). We regard the record from Grevillea armigera (Proteaceae) as the result of commingling of specimens in the field.

DISTRIBUTION (map 5): Known from nine localities in the Goldfields, Great Southern, Southwest, and coastal portions of Mid-West and Gascoyne regions of Western Australia. This new western species is found in the southwest interzone, southwestern and western desert phytogeographical subregions.

DISCUSSION: This is one of the most frequently collected species of Myrtaceae-feeding Exocarpocorina as well as having probably the broadest host range.
