Ricinoides is an arthropod genus in the family Ricinoididae, first described by Henry Ewing in 1929.^[2]

Distribution

Species in this genus are found in West Africa.

Species

As of October 2022 it contains sixteen species:^[3]

Ricinoides afzelii (Thorell, 1892) — Ghana, Guinea, Sierra Leone
Ricinoides atewa Naskrecki, 2008 — Ghana
Ricinoides crassipalpe (Hansen & Sørensen, 1904) — Cameroon, Equatorial Guinea
Ricinoides eburneus Botero-Trujillo, Sain & Prendini, 2021 — Côte d’Ivoire
Ricinoides feae (Hansen, 1921) — Guinea, Guinea-Bissau
Ricinoides hanseni Legg, 1976 — Sierra Leone
Ricinoides iita Botero-Trujillo, Sain & Prendini, 2021 — Nigeria
Ricinoides kakum Botero-Trujillo, Sain & Prendini, 2021 — Ghana
Ricinoides karschii (Hansen & Sørensen, 1904) — Cameroon, Congo, Gabon
Ricinoides leonensis Legg, 1978 — Sierra Leone
Ricinoides megahanseni Legg, 1982 — Côte d’Ivoire
Ricinoides nzerekorensis Botero-Trujillo, Sain & Prendini, 2021 — Guinea
Ricinoides olounoua Legg, 1978 — Cameroon

In 2026, it was proposed that several species attributed to Ricinoides should be split out into several newly described genera, giving the new combinations Alantakun karschii, Bambara hanseni, Bambara megahanseni, Gizoo crassipalpe, Tautau leonensis, and Ududo sjostedtii.^[4]
