Omnivoriphylus , new genus

TYPE SPECIES: Omnivoriphylus mangaensis , new species.

DIAGNOSIS: This group of diverse habitus is held together by the structure of the sigmoid endosoma, with one or two slender apical spines of length about equal to length of secondary gonopore (figs. 65–69, pl. 23). Similar in endosomal structure to Myoporophylus , but that taxon of uniform yellow coloration (in preserved specimens) and robust body form in contrast to the smaller and usually more slender-bodied Omnivoriphylus spp. most of which have black spots on the corium at the inner angle of the cuneus and at the apex of the membrane cells.

DESCRIPTION: MALE: Ranging from long and parallel sided to shorter and ovoid; total length 3.98–4.70, pronotum width 0.84–1.20. COLORATION (pl. 22): Variable, ranging from pale and translucent with dark spots at apex of corium and on membrane to more rarely opaque and unicolorous or with areas of infuscation. SURFACE AND VESTI- TURE (fig. 64A–C, pl. 22): Body surface smooth, weakly shining; vestiture either pale or dark, reclining, common setae. STRUC- TURE: Head (fig. 64A, pl. 22): Moderately broad, sometimes closely conforming to anterior margin of pronotum, eyes variable, sometimes bulging; segment 2 ranging from short and tapering proximally to long and parallel sided. Thorax (fig. 64A–C, pl. 22): Pronotum with lateral margins nearly straight, calli weakly demarcated, posterior lobe nearly flat to weakly elevated, posterior margin straight to weakly excavate; mesoscutum narrowly to broadly exposed. Thoracic pleuron as in figure 64D. Pretarsus as in figure 64E, F. Hemelytron: Corial margin ranging from distinctly convex to straight. GENITALIA (figs. 65–69, pl. 23): Pygophore: Elongate conical, posterior margin truncate, with various arrangement of bristles, usually without tubercles on dorsal surface. Endosoma: Small, slender to very slender, sigmoid, length of apical portion variable, dorsal and ventral straps contiguous from base to region of secondary gonopore, dorsal strap forming one apical spine of length approximately equal to length of secondary gonopore, sometimes apical spine bifid; ventral strap reaching to apex of well-sclerotized, subapically placed secondary gonopore. Phallotheca: Apical portion narrowly conical, usually without narrow dorsal crest, aperture either on anterior dorsal surface or apical; basal portion reaching to middle of ventral surface of pygophore in situ. Parameres: Variable, sometimes elongate in dorsal view; dorsoposterior margin usually strongly elevated above posterior and anterior processes; posterior process with undulating lateral margin in dorsal view, distal portion straight or deflected; development of anterior process and placement of prominent seta variable. Right paramere of moderate size, usually with two small points apically, rarely with long, narrow medial projection.

FEMALE (pl. 22): Total length 3.04–4.20, pronotum width 0.85–1.22; coloration, vestiture, and body form similar to male. GENI- TALIA (pl. 51): Subgenital plate of sternite 6: Concave medially. Vestibular sclerites: Moderately large, reaching anterior margins of sclerotized rings. First gonapophyses: Relatively small or medium-sized quadrate basal blocks, with variable margins. Ventral labiate plate: Platelike medial anteroventral extension wider than lateral extent of basal gonapophysal structures, anterior surface undulate or smoothly curved, covering anterior surface of basal structures. Dorsal labiate plate: Medium sized, relatively short. Sclerotized rings: Medium-sized elongate ovoid, or large triangular; relatively flat, thick walled. Posteromedial region: Surface with some microstructure. Anterolateral region: Anterior margin extending beyond anterior edge of sclerotized rings, sometimes with strongly undulate or strongly spiculate anterior margin. Posterior wall: Intersegmental structure: Not differentiated from connecting membrane. Interramal sclerites: Moderately sclerotized, lateral sclerites broad, medial sclerite not observed.

ETYMOLOGY: From the Latin, omnis, “all,” and vorare, “to devour,” and the generic name Phylus ; masculine.

DISCUSSION: The endosomal structure of Omnivoriphylus spp. is similar to that of species we place in Myoporophylus . We have chosen to maintain these species in separate genera because of the wrinkled integument, large body size, and consistent host preferences in Myoporophylus . This decision leaves Omnivoriphylus as a group of diverse habitus and host associations, but nonetheless one in which all species have similar endosomal structure.
