Abstract

Crocisa calceata Vachal, 1903 (Figs 26; 27) Crocisa calceata Vachal, 1903a: 380. MATERIAL EXAMINED. — Central African Republic • 1♀; Fort Sibut, Haut Chari, Congo français; Le Moult leg.; T. J. Wood det.; MNHN-EY-EY58584 (ex. coll. De Gaulle 1919). Gabon • 1♂ (lectotype by present designation); Lastourv[ille]; 1.VIII.-30.IX.1898; Bouyssou leg.; MNHN-EY-EY58550. Sierra Leone • 1♀ (paralectotype by present designation); MNHN-EY-EY58549. CURRENT STATUS. — Thyreus calceatus (Vachal,1903) (Eardley 1991). DISTRIBUTION. — Senegal, Sierra Leone, Nigeria, Cameroon, Gabon, Central African Republic*, Republic of the Congo, Democratic Republic of the Congo, Uganda, Ethiopia,Kenya,Tanzania, Malawi, Zambia, Mozambique, Zimbabwe, Namibia, Lesotho, South Africa (Eardley 1991; Ascher & Pickering 2025). REMARKS Vachal described C. calceata from specimens from Lastourville [Gabon], Sierra Leone, Ouganda [Uganda], Dakar [Senegal], and the Belgian Congo [Democratic Republic of the Congo]. Eardley (1991: 42) wrote: “Cockerell (1937b), in taking Lastourville as the type locality of this species, designated the specimen from this locality as the lectotype of this species”. Cockerell (1937: 28) specifically wrote: “Lastourville, being the first locality cited is to be taken as the type-locality of C. calceata ”. Under ICZN (1999) Article 74.5 this does not constitute a valid lectotype designation, as Cockerell did not use the term lectotype or its equivalent (e.g. “the type”), he did not examine the material directly, and did not explicitly select a syntype to act as the unique name-bearing type of the taxon. His writing only implicitly indicates that the syntype from Lastourville should be representative of the species. This is a minor quibble, and in order to maintain consistency with the revision of Eardley, this male specimen from Lastourville is hereby designated as the lectotype. An additional paralectotype from Sierra Leone is present in the MNHN collection that was not recognised by Eardley as being part of the original type series, even though he examined and determined it (Fig. 27A). Finally,the genital capsule from the lectotype male had been extracted and stored in a glycerine vial. It was possible to extract the capsule and mount it on card, though some aspects of the capsule were obscured by thick gelatine (Fig. 26F).
