Taxonavigation

Ordo: Siphonophorida
Familia: Siphonorhinidae

Name

Illacme Cook & Loomis, 1928 – Wikispecies link – Pensoft Profile

Type species

Illacme plenipes Cook & Loomis, 1928.

Species included

Illacme plenipes Cook & Loomis, 1928; Illacme tobini Marek, Krejca & Shear, 2016; Illacme socal sp. nov.

Family placement

The genus Illacme is placed in the family Siphonorhinidae based on the following morphological characters: Head pear-shaped (♂) or triangular (♀), not elongate nor with a beak, as in the Siphonophoridae (♂ Suppl. materials 1, 9: figs S1, S2, S32, S34; ♀ Fig. 1; Suppl. material 11: figs S36, S39). Antennae elbowed between antennomeres 3, 4 (Figs 1, 2; Suppl. materials 1, 10, 11: figs S2–S4, S36, S41). Antennomere 1 set deep in cranium, not fully visible dorsally as in Siphonophoridae (Suppl. material 1: figs S2, S4). Antennomere 2 longer than wide, conical, not doughnut-shaped nor wider than long as typical in Siphonophoridae (Suppl. material 1: figs S1, S4). Anterior margin of collum straight, not medially emarginate as in Siphonophoridae. Sterna with prominent midline triangular ridge, projecting ventrally (Suppl. material 5: fig. S19). Posterior gonopods with distal podomere divided into 2–5 branches with one branch spike-like (i–v, Fig. 3B; Suppl. material 7: figs S25–S27). See also diagnoses of Illacme in Shelley (1996b[1]: 23), Marek et al. (2012[2]: 85; 2016[3]: 7), and Enghoff et al. (2015[4]: 386); and of Siphonorhinidae in Shelley and Hoffman (2004[5]: 218), Wesener (2014[6]: 417), and Enghoff et al. (2015[4]: 386).
