Ardila Rodriguez Universidad Metropolitana, Barranquilla, Col ombia. Carlos_ardil a45 @latinmai!.com Received February 2006, received in revised form 26 April2006, accepted 02 May 2006 Abstract A new species of fish, Callichthys aibaensis sp.nov., is described for the Department of Santande r (Colombia), captured near the headwaters of a smallaffluent of the River Oibita ( 1450 m of altitude), which is a tributary of the River Suarez , who in turn empties into the Sogamoso Ri ver, and finally this into the River Magdalena. This is the first record of CaJlichthys for the we st part of the Eastern Andean Co rdille ra of Colombia. The new species differs from oth ers Callichthys, because its larger number of vertebrae, the inter­ ception of the first pterigiofore of the analfinthat occurs inth e 19th vertebrae in males and in the 18th verte brae in females. The plates of the poster ior region ofth e supraoccipitalare bare .The centre part ofth e first predor­ sal plate is not united . The hyomandibular bone is morphologically different from C. Fabriciai. The pa­ rasphenoid , vomer and mesethmoid are completly different to allthe known species of CalJichthys. The med ially interdigitated suture of the d eithrum withthe caracoid has a different shape of that of C. fabri­ ciol, The pelvic girdle of Callichthys aibaensis has an ischiatic proce ss, a basiptherygium and an intern al and exte rnal process that differs to allthe known species. Ca/lichthys a/baensis is the smallest known species of Callichthyinae. Key words: Ca/lichthys oiboensis sp.nov., River Magdalena w ate r system, Colombia. Resumen Se de scribe una nueva especie de pez, Callichthys aibaensis sp.nov., para el Departamento de San­ tander, colectado cerca del nacimiento de un pequerio aflue nte del RIoOibita ( 1450 rn.s.n.rn), el cual es afluente del RioSuarez que desemboca en el RioSogarnoso, que finalmente vierte sus aguas al RIo Mag­ dalena. Este es el primer registro de Callichthys que se tien e para la parte occide ntal de la Cordillera Oriental de Colombia. La nueva especie se distingue de otros Callichthys por el mayor nurnero de vertebras, la intercep­ ci6n del primer pterigi6foro de laaleta anal se da en lavertebra 19en los machos yen laverteb ra IBen las hem bras .

  • Cascadu, Flat-Head Or Chato
    UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour Callichthys callichthys (Flat-head Cascadu or Chato) Family: Callichthyidae (Plated Catfish) Order: Siluriformes (Catfish) Class: Actinopterygii (Ray-finned Fish) Fig. 1. Flat-head cascade, Callichthys callichthys. [“http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=335”, Downloaded 10th October 2011] TRAITS. Was first described by Linnaeus in 1758 and was named Silurus callichthys. They generally reach a maximum length of 20 cm and can weigh up to 80g.(Froese and Pauly, 2001) The females are generally larger and more robust as compared to the males. The Callichthys callichthys is an elongated catfish with a straight or flattened belly profile. It also has a broad flattened head and a body which is almost uniform in breath with some posterior tapering which beings after dorsal fin. (Figure 2) Its body consists of 2 rows of overlapping plates or scutes. Approximately 26 – 29 scutes seen on the upper lateral series and 25 – 28 scutes seen on the lower lateral series. The fins are rounded and the fish also has a total of 6-8 soft dorsal rays. It also has 2 pairs of maxillary barbles near its mouth and small eyes. The fish has an inferior type mouth ( Berra, 2007). The Callichthys callichthys is dark olive green in colour to a grey brown as seen in Figure 1, with the males having a blue to violet sheen on its flanks. ECOLOGY. Callichthys callichthys is a freshwater organism which is primarily riverine in habitat (Arratia, 2003). Only 2 families of catfishes are found to colonise marine habitats UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour (Arratia, 2003).

  • Technical Progress Report IABIN INVASIVE SPECIES THEMATIC
    Technical Progress Report IABIN INVASIVE SPECIES THEMATIC NETWORK CONTENT BUILDING PROJECT IMPLEMENT, UPDATE AND MAINTAIN AN I3N IAS DATABASE IN JAMAICA For the period May 19, 2006 -November 16, 2006 Submitted by Sean Townsend I3N Lead Jamaica Senior Research Officer-Ja-CHM & Dionne Newell IABIN Focal Point Senior Research Officer-Entomology Natural History Division Institute of Jamaica 10-16 East Street Kingston, Jamaica EXECUTIVE SUMMARY The IABIN Content-Building project for I3N Jamaica is the second IABIN project being administered and spearheaded by the Natural History Division (NHD) of the Institute of Jamaica. The project facilitates the improvement of the current database on invasive alien species found in Jamaica. The development of posters and brochures are additional components of the project that seek to increase the awareness of the general public on the presence and effects of alien invasives in Jamaica. These new materials will compliment the existing brochure that was produced in the pilot project in 2002. In addition, the educational materials to be produced would serve to better inform decision makers on matters concerning invasive alien species. Using the current standards and protocols developed by IABIN-I3N, the database contains to date, 24 species of which 23 are validated and 70 occurrences of which all are validated. Difficulties have included obtaining the raw data used to develop the original database. The main challenge is finding information on the impacts that invasives have on local biodiversity as well as obtaining specific details of introductions. The process of obtaining and inputting of data is becoming less challenging with increased usage of the database.

Festlegung des Neotypus und des locus typicus von Callichthys callichthys (Linnaeus, 1758) JOACHIM KNAACK Am Walde 5a, 16775 Neuglobsow Received on March 20, 2008, accepted on April 2, 2008. Published online at www.vertebrate-zoology.de on May 12, 2008. > Abstract The syntypes of Silurus callichthys LINNAEUS, 1758 – type species of the genus Callichthys – are lost long time ago. Proper diagnoses of the genus and species within the genus Callichthys are impossible without the correct knowledge of the features of the type species. That’s why the designation of a neotype and the restriction of the locus typicus of Callichthys callichthys (LINNAEUS, 1758) was needed. This species is in South America widely distributed (from Suriname to Buenos Aires). Artifi - cial mixed breeding groups of populations from Suriname, Bolivia, Paraguay, Uruguay and Argentina were used to test the fertility. All fi shes were fertile up to F2. > Resumen Los sintipos de Silurus callichthys LINNAEUS, 1758 – la especie tipo del género Callichthys – se han perdido hace mucho tiempo. Diagnosis correctas tanto del Género en sí, como de las especies dentro de éste no son posibles sin un conocimiento exacto de las características de la especie tipo de este género. Por esta razón fue necesaria la designación de un neotipo, restringiéndolo a la localidad tipo de Callichthys callichthys (LINNAEUS, 1758). Esta especie tiene una amplia distribución en Sudamérica (Desde Surinam hasta la provincia de Buenos Aires). Grupos mixtos de distintas poblaciones de Surinam, Bolivia, Paraguay y Uruguay fueron hibridizados y criados artifi cialmente, demostrándose su fertilidad en la generación F2.
