Diagnosis: Spade-shaped, dorsoventrally flattened Clevelandella with average length in protargol preparations 69 µm, mean 31 adoral membranelles, posterior protrusion of left lobe of anterior body part overhanging up to one-third of peristomial projection, and with teardrop-shaped or ellipsoidal macronucleus.

Etymology: Named in honour of Mr Philip Komong, our collaborator from Papua New Guinea.

Type locality: Papua New Guinea, Wanang 3, N5.228, E145.080 .

Type host: Salganea ternatensis hirsuta Roth , 1979.

Type material: A protargol-impregnated holotype cell ( Fig. 7C , D) marked in a black circle on a slide deposited in the collection of the National Museum of the Czech Republic, Prague, Czech Republic, inventory number P6E 5381 .

Figure 7. Clevelandella philipi sp. nov., in vivo (A, B) and after protargol impregnation (C–I). From STH (A–G) and ASS (H, I). A, ventral view showing thick, hyaline cortical layer (between black arrowheads), cilia of the circumperistomial kineties (black arrow) and adoral membranelles (white arrow). B, ventral view showing posterior extent of somatic ciliation (white arrowheads).Note variability of macronuclear shape (A, B). C, ventral infraciliature with detail (inset) showing right sutural kinetofragments (white arrowheads). D, dorsal view showing infraciliature, ciliated circumperistomial kineties (black arrow), looping kineties of peristomial projection (white arrow), and cytoproct (black arrowhead).E, ventral view showing left-hand spiralling ventral somatic kineties (black asterisk) and right sutural kinetofragments (black arrowhead).F, dorsal view showing straight somatic kineties (white asterisk), disordered basal bodies on left protuberance (white arrow), and paroral membrane (black arrowhead). G, dorsal view showing micronucleus (white arrowhead). H, dorsal view showing straight dorsal somatic kineties (asterisk), proximal margin of the peristomial overture (white arrow), and looping kineties of peristomial projection (black arrowhead). I, detail view showing diplostichomonad paroral membrane composed of shorter right file (black arrowhead) and longer left file (white arrowhead) of basal bodies. Ma, macronucleus. Scale bars:20 µm (A–H) 10 µm (I).
