Camallanidae Railliet et Henry, 1915

Procamallanus (Procamallanus) laeviconchus (Wedl, 1861)

Syn.: Cucullanus laeviconchus Wedl, 1861

Hosts: Synodontis greshoffi , Congo squeaker S. pleurops (both Siluriformes : Mochokidae ), Chrysichthys sp. ( Siluriformes : Claroteidae ) and longsnout distichodus Distichodus lusosso ( Characiformes : Distichodontidae ).

Site of infection: Stomach.

Locality : Sangha River adjacent to Sangha Lodge, 02°59'06''N; 16°13'59''E (Congo basin), DSPA, Central African Republic (collected 11–15 September 2012) .

Prevalence and intensity: S. greshoffi : 5 fish infected/7 fish examined; 2–13 (mean 5) nematodes. S. pleurops : 3/3; 1–2. Chrysichthys sp. : 1/1; 1. D. lusosso : 1/1; 10.

Deposition of voucher specimens: IPCAS N-13.

Remarks. This species has already been redescribed in detail by Moravec and Van As (2004, 2015c). According to Moravec and Scholz (2017), Procamallanus (P.) laeviconchus has so far been recorded from ten different Synodontis spp. , which may be considered its main definitive hosts, and from Schilbe intermedius (Schilbeidae) in Egypt, Sudan, Chad, Ghana, Nigeria, Benin, Botswana, Uganda and the Democratic Republic of the Congo. Previously this species has been reported from about 30 fish species belonging to seven families in many African countries, but apparently other species have been misidentified under this name (see Campana-Rouget 1961, Moravec and Van As 2004). Distichodus spp. have already been reported as hosts of P. (P.) laeviconchus (see Khalil and Polling 1997, Mašová et al. 2011). The present finding of this nematode in the claroteid catfish Chrysichthys sp. represents a new host record. This nematode species is reported from the Central African Republic for the first time.
