Etymology: Phalloceros: Greek, phallos = penis + Greek, keras = horn (Ref. 45335); lucenorum: The specific name lucenorum is a patronym for Carlos A.S. Lucena and Zilda Margarete S. Lucena, in recognition of their many contributions to Neotropical ichthyology.
Eponymy: Dr Zilda Margarete Seixas de Lucena is a zoologist and ichthyologist, as is her husband Dr Carlos Alberto Santos de Lucena (above). [...] (Ref. 128868), visit book page.

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 7 - 8; 臀鰭軟條: 9 - 11; 脊椎骨: 31 - 32. Diagnosed autapomorphically by the rectangular tip of hook on left half of gonopodial appendix (vs. rounded tip). Can be differentiated from its congeners except Phalloceros megapolos, Phalloceros spiloura, Phalloceros malabarbai, Phalloceros alessandrae, Phalloceros buckupi, Phalloceros uai, Phalloceros anisophallos, Phalloceros pellos, and Phalloceros reisi by the female urogenital papilla curved to the right, located laterally (vs. slightly left turned and with a lateral ramus or straight located along midventral line) and border of the anal aperture in contact with the first anal-fin ray or very close to it (vs. separated from first anal-fin ray by the female urogenital papilla). Differs further from its congeners except Phalloceros spiloura, Phalloceros uai, Phalloceros anisophallos, Phalloceros pellos, and Phalloceros reisi by the absence of the right hook and presence of the left one (vs. absence or presence of left and right hooks); and gonopodial appendix asymmetrical, its halves different from each other; right half wider than left one (vs. gonopodial appendix symmetrical; its halves similar to each other). Can be separated from Phalloceros spiloura by the absence of a caudal peduncle spot (vs. presence of caudal peduncle spot); from Phalloceros uai by the presence of a wide and square-shaped lateral spot in large specimens (vs. absence of such spot); from Phalloceros anisophallos by the lateral spot in adult females elliptical to roundish, but never forming a vertical bar (vs. lateral spot very narrow, forming a vertically elongated bar covering up to the length corresponding to two scales length in horizontal direction and 2-4 scales in vertical direction); from Phalloceros reisi by lateral spot always present and evident not covering the length corresponding to more than two scales length in horizontal or vertical directions (vs. lateral spot absent or small and discrete not covering the length corresponding to one or two scales length in horizontal or vertical directions) (Ref. 76852).
