According to the genealogical accounts preserved in classical summaries, Alcmenor is one of the sons of King Aegyptus. In the version reported in the cited summaries his mother is described as an Arabian woman, making him full brother to Istrus, Chalcodon, Agenor, Chaetus, Diocorystes, Alces, Hippothous, Euchenor and Hippolytus. Other sources present variant parentage, naming Eurryroe (daughter of the river-god Nilus) or Isaie (daughter of King Agenor of Tyre) as possible mothers of Aegyptus's sons, indicating multiple tradition-variants recorded by ancient compilers (sources cite Apollodorus and scholiastic/Tzetzes traditions as the loci of such variants).
No physical description or iconographic detail for Alcmenor is provided in the cited sources; he appears only as a named participant in genealogical lists and the Danaid wedding-night narrative.
The provided sources do not ascribe any supernatural powers or special abilities to Alcmenor. His role in the tradition is that of a mortal prince whose principal narrative action is marriage to a daughter of Danaus and subsequent death on his wedding night, situating him as a victim within the Danaid massacre motif.

Lynceus
Lynceus is a recurring proper name in Greek myth borne by several distinct human figures (and once by a hound) rather than a single supernatural class. Bearers of the name appear across heroic and founding narratives — notably as a son of Aegyptus who survives the Danaid massacre and becomes king of Argos, and as Lynceus son of Aphareus, an Argonaut noted for his role as lookout of the Argo.

Danaus
Danaus is a mythic founding-king figure in ancient Greek tradition, remembered as the eponymous ancestor of the Danaids and as a culture-hero whose migration from Egypt/Libya to Argos explains local institutions, place-names, and cultic associations in archaic and classical lore.
