Lytorhynchus gaddi Nikolsky |

Lytorhynchus diadema gaddi Leviton, Anderson, Adler & Minton 1992 |
Remarks:
Previously regarded as a subspecies or a synonym of diadema (e.g., Arnold 1980; Baha el Din 2006; Sindaco, Venchi & Grieco 2013).
Others have regarded it as a separate species (e.g., Leviton & Anderson 1970; Schätti & Gasperetti 1994).
Alshammari, Badry, Busais, Ibrahim & El-Abd (2021) presented evidence supporting the recognition of gaddi as a separate species.
Distribution:

Lytorhynchus kennedyi Schmidt |
|
| |
Lytorhynchus diadema kennedyi Schmidt 1952 |
Remarks:
Status unclear.
It has been regarded as a synonym of diadema (e.g., Moravec 1995; Disi, Modrý, Necas & Rifai 2001; Amr & Disi 2011) or a subspecies of same
(e.g., Leviton, Anderson, Adler & Minton 1992).
It is regarded herein as a separate species, following several authors (e.g., Gasperetti 1988; Martens 1993; Baha el Din 2006; Sindaco, Venchi & Grieco 2013),
supported by near-sympatry in southern Jordan (Al-Oran 2000).
An isolated record of kennedyi in northeastern Libya was regarded as an aberrantly patterned diadema by Bauer, DeBoer & Taylor (2017).
Distribution:
Iraq,
Jordan,
Saudi Arabia,
Syria.
