Literature ornatus

Gray, 1866

Callithrix ornata n. sp.

Distribution: New Granada.

Description: Fur black and grey, punctuated; forehead and ears white; temple, cheeks, throat, underside of body, and inner side of the legs bright red chestnut; hands and feet grey; tail black, grey-washed; hair of tail pale, with a broad sub terminal ring.

Remark: Received from M. Verreaux as C. discolor of I. Geoffroy; but that species has red-chestnut hands. It is more like C. moloch, and may be a variety of it; but it differs greatly from Geoffroy and Dahlbom’s description.

Callithrix ornatus

Synonyms: Callithrix ornata (Gray, 1866); C. discolor (Verreaux, not Geoffroy).

Distribution: New Granada.

Description: Black-and-grey grizzled; forehead and ears white; temples, cheeks, throat, underside of body, and inner side of legs bright-red chestnut; hands and feet grey; tail blackish, grey-washed; hairs of tail pale, with a broad sub terminal ring.

Schlegel, 1876

Callithrix ornata

Synonyms: Callithrix ornata (Gray, 1866, 1870).

Description: The Callithrix ornata resembles in general C. cuprea and caligata; but it distinguishes itself clearly:
1) by the hairs on the ears that are white and not red or black as in the other species,
2) by the four hands, not black or coppery-red, but covered -at least the fingers- by whitish hairs,
3) by the presence of a frontal band of more or less pure grey-white,
4) by the coppery-red that only extends to the internal side of the limbs, of the under-arms and legs.

Remarks: The individuals of this species originate from Colombia, and have been send by Verreaux to the British and Dutch museums under the name C. discolor. However, the figure and description of C. discolor attributes to C. cuprea de Spix, it is clear that the form can be rejected, following the example of Gray, even in the case that Is. Geoffroy has confused the two species, which is very well possible, knowing that the two individuals, obtained by Castelnau near Sarayacu on the margins of the Ucayali differ from the others by their speckled light grey front and the partially whitish hairs on the fingers of one.
The Leiden museum has one specimen, sent from Colombia by Verreaux, with a white frontal band that is strongly speckled with black. Another specimen from St. Fé da Bogota resembles very much the first, but the area between the ears is strongly drawing into dark brown-reddish. Two other specimens, thought to come from Peru, have strongly pronounced white frontal bands.

Callicebus ornatus

Synonyms: Callithrix ornata (Gray, 1866); Callithrix ornatus (Gray, 1870); Callithrix discolor (Martinez, 1873); Callicebus ornatus (Thomas, 1908).

Distribution: The forests of the Cordillera Oriental of Colombia.

Remarks: Although the distribution of the colours may indicate that this Callicebus belongs to C. moloch, for geographical reason we do not include it in this species, as until today none of the forms that  with certainty can refer to this species can be found north of the Amazonas. It is however possible that some intermediate subspecies exists between the river-basins of the Caqueta and Vaupes.

Hill, 1955

Callicebus cupreus ornatus

Description: A fine specimen of this handsome titi. It is recognised by the broad white frontal band, bordered below by a stiff black supra-orbital fringe and behind by the red-brown vertex. The cheek-fringes are bright coppery red, the throat hairs elongated. There is a white tuft on the concave aspect of each ear. The accompanying diagram illustrates the direction of the short white hairs on the face. General colour of the upper parts grey-brown, speckled from the annulations of the individual hairs; under parts dull orange. Forearms and shanks bright red; hands and feet buffy white. Tail grizzled grey with longer black hairs interspersed among the ordinary annulated hairs (bases of tail white, with succeeding black annulations and grey tips). End of tail slightly bushier and a trifle paler.
There seems no reason to separate this from specifically as it merely replaces cupreus to the north of the range.

Remark: The Scottish Museum has one specimen, 1868/2/20, purchased from Gerrard.

Callicebus cupreus ornatus

Synonym: Callithrix discolor (Martinez, 1873).

Type locality: Vicinity of Bogota, Colombia. Type in British Museum.

Distribution: Colombia. Recorded from the vicinity of Bogota. Material in British Museum is labelled Medina, Upper Meta river. Allen records it from Villavicencio and from Barrigon, 10 miles farther east.

Description: The most northern representative of the cupreus group. Forehead with row of black superciliary hairs succeeded by broad white transverse band. Crown red brown; sides of head, cheeks, throat and whole under surface of body, also medial surface of limbs, bright chestnut-red; throat hairs elongated; ears with tuft of white hairs on their concave aspect. General colour of upper surface of body grey-brown, due to grizzled effect produced by annulations on individual hairs. Forearms and legs below knee bright chestnut-red; hands and feet buffy white; tail black, washed with grey, the hairs pale grey basally with black terminal zone; end of tail slightly bushier and a trifle paler.

Skull: measurements in publication.

Callicebus moloch ornatus

Synonyms: Callithrix ornata (Gray, 1866); Callicebus ornatus (Elliot, 1913); Callicebus cupreus ornatus (Hill, 1960).

Type locality: New Grenada, here restricted to the Villavicencio region, upper Rio Meta, Meta, Colombia. Type in British Museum.

Distribution: Eastern Colombia from the base of the Cordillera Oriental, eastern Cundinamarca, and the gallery forests of the Villavicencio region, western Meta in the upper Rio Meta basin, southward to the Macarena Mountains and north bank of the Rio Guayabero, a tributary of the Rio Guaviare; altitudinal range from approximately 300 to 600 meters above sea level.

Description: (key to species:) general body colour grey, reddish or brown; under parts like back or sharply defined reddish orange or buff; hind feet black, brown, red or grey, tail grey or blackish with tip grey or grey mixed with black; throat like chest; forearms grey, red, dark brown sometimes blackish above; upper surface of hands grey to blackish never sharply contrasted with colour of upper side of wrists.
Forehead grey sometimes edged with black or dominantly black to blackish brown and always well defined from posterior half of crown and nape, outer side of forearms grizzled or more or less uniformly reddish to dark brown. Forehead with grey band often thinly edged with black; under parts of body orange or reddish and always well defined from sides; forearms uniformly orange or reddish or contrasting grizzled on outer side; tail dominantly grey. Forearms and hind legs dominantly grey above uniformly rufous beneath.

Measurements: see table in publication.

Remarks: The series of titis from the localities listed below are practically indistinguishable from each other. The characteristic whitish frontal blaze is well developed and sharply contrasted with the chestnut red crown. The grey of outer sides of limbs extends from sides of body to knees and elbows in all specimens and half way to ankles and wrists in most specimens; in some the grey continues as a thin line to hands and feet. The fingers and toes are always grey while the upper surface of the hands and feet are usually pale in contrast with the reddish wrists and ankles. This colour pattern of the forelimbs recalls that of its only co generic neighbour, C. torquatus lugens. The tail of ornatus ranges from dominantly buffy or grey to blackish grey.
Intergradation between ornatus and discolor is complete and except for their complete geographic separation, the first might be regarded as little better than a local colour variety of the second.
Callicebus moloch ornatus was first described from New Granada, i.e. Colombia, without further locality data. Subsequently, skins labelled Bogotá or Santa Fé de Bogotá, reached museums through dealers. The old Santa Fé de Bogotá extended from the Rio Magdalena on the west to the Rio Orinoco on the east. Not until 1916, when Allen recorded specimens from Villavicencio and Barrigón in the upper Rio Meta region, did the true habitat of ornatus become known.

Species examined: Colombia – Meta: Rio Guapaya, La Macarena; Los Micos, La Macarena; San Juan de Arama; San Martin; Villavicencio.

De Boer, 1974

Callicebus moloch ornatus

1 individual, unknown origin.
Diploid number 2n = 46. 24 biarmed and 24 acrocentric chromosomes
The arrangement and the structure of the autosome pairs are nearly identical to those of C. moloch cupreus.

The cytological information suggests that the forms cupreus and ornatus on the one hand, and donacophilus on the other, may be more than only subspecifically distinct.

Hernandez-Camacho and Cooper, 1976

Callicebus moloch ornatus

Distribution: In the department of Meta, C. m. ornatus occurs in the piedmont to an upper altitudinal limit of about 500m as well in the adjacent lowland gallery forests. It is marginally sympatric with C. torquatus lugens along both banks of the Guayabero River at the southern extreme of its range. Its northernmost occurrence is the lower Upía River, a northern tributary of the Meta River.

Hershkovitz, 1988

Callicebus cupreus ornatus

Member of the moloch group.

Remarks: Complete isolation of the northern titi fraction led to divergence from the southern fraction of ancestral stock. Modern C. c. ornatus, separated from C. c. discolor by a swath no less than 350 km wide, still retains all specific markings including reddish sideburns, under parts, and trend towards pheomelanization of limbs. Affinity with nearest relative discolor is shown by the whitish transverse frontal blaze, marbled tail, and other shared derived features. The crown, however, still dominantly agouti in discolor, is pheomelanized in ornatus. In contrast, outer surface of lower arms and legs, completely pheomelanized in discolor, retain in ornatus most of the common ancestral agouti.
Differentiation of ornatus from discolor has been divergent with respect to some characters, and allometrically clinal in others. Notwithstanding marked changes, morphological separation is not quite complete, and hardly or not in all juveniles, perhaps of recency of genetic isolation. This suggests that reproductive and social isolation between ornatus and discolor is also incomplete. The two forms interbreed in captivity and produce fertile offspring. Their karyotypes are the same. These considerations suggest that ornatus may be best treated as a subspecies within the species Callicebus cupreus.

Callicebus moloch ornatus

Distribution: the foothills of the Orinoco and adjacent forests in Cundinamarca (Medina) and Meta, in the northeast till the Rio Upía (and possibly Casanare), till the right bank of the Rio Guayabero (one specimen of the right margin, collected in El Refugio = La Macarena), including the base of the Serranía de la La Macarena.

Hershkovitz, 1990

Callicebus cupreus ornatus

Member of the moloch Group.

Synonym: Callithrix ornata (Gray, 1866).

Type locality: “Nouvelle Grenade,” now Colombia, restricted to the Villavicencio region, Rio Meta, Meta, by Hershkovitz (1963). Holotype in the British Museum.

Distribution: Eastern Colombia from extreme south-eastern Cundinamarca (Medina) south, into the department of Meta, along the base of the Cordillera Oriental and the Sierra de Macarena to the Rio Guayabero, upper Rio Guaviare. Hernandez-Camacho and Cooper (1976) give the northern limits of the range as the lower Rio Upia, a tributary of the Rio Meta, in Meta department. Two Medina specimens in the British Museum (Natural History) were subsequently recorded by Napier (1976). At the southern extreme of the range Callicebus cupreus ornatus, according to Hernandez-Camacho and Cooper (1976, p. 56), “is marginally sympatric with C. lugens along both banks of the Guayabero River.” Olivares (1962, p. 307) observed the two species on the left bank of the Guayabero but did not mention them living on the right bank. This bank of the Guayabero is largely savannah bordered by gallery forests.
Callicebus cupreus ornatus and C. torquatus are the only forms of the genus known to occur in the upper Rio Orinoco basin. The geographic gap of approximately 350 km separating C. c. ornatus from its nearest relative, C. c. discolor, is occupied by Callicebus torquatus medemi.

Description: Pale frontal blaze or transverse band present; crown reddish brown to nearly blackish, hair bases buffy or whitish; sideburns, under parts, and inner side of limbs reddish; outer side of thighs and upper arms buffy agouti like sides of body; outer side of legs and lower part of forearms reddish, digits contrastingly pale.

Measurements: See publication.

Comparisons: Distinguished from C. cupreus discolor, C. c. cupreus, and C. dubius by pale or whitish digits contrasting with reddish ankles and wrists; from C. oenanthe by uniformly reddish sideburns, crown dominantly reddish to reddish brown; from C. brunneus and C. caligatus by buffy or whitish frontal transverse blaze; from other forms of Callicebus by one or more of the preceding characters.

Specimens examined: Total 99, all from Colombia.Cundinamarca: Medina; Meta: Agua Clara (Cano); Barbascal; Barrigon; Los Micos; Rio Guapayo, La Macarena; Rio Guayabero; Restrepo; San Martin; Villavicencio.

Callicebus cupreus ornatus

Based on cranial measurements, the genus can be divided in five groups:

  • the donacophilus group (including modestus, olallae, d. donacophilus and d. pallescens)
  • the cupreus group (including caligatus, c. cupreus, c. discolor and c. ornatus)
  • the moloch group (including brunneus, h. hoffmannsi, h. baptista, moloch and cinerascens)
  • the personatus group (including p. personatus, p. nigrifrons, p. melanochir)
  • the torquatus group (including t. lucifer, t. lugens, t. medemi, t. regulus, t. purinus and t. torquatus).

The group position of C. dubius remains uncertain; C. oenanthe and C. barbarabrownae were not examined.

Callicebus ornatus

Type locality: Villavicencio region, Río Meta, Department of Meta, Colombia. The holotype is a skin and skull purchased from Maison Verraux, Paris, France, and deposited as no. 1859.7.9.4 in the British Museum of Natural History, London, U.K.

Distribution: Eastern Colombia, from the department of Cundinamarca (Medina), north as far as the lower Río Upía/Río Meta, and south into the department of Meta, along the base of the Cordillera Oriental and the Sierra de la Macarena to the Río Guayabero/upper Río Guaviare. This species is the only member of the cupreus and moloch Group occurring north of the Rios Amazonas/Solimões/Napo axis, in the upper Río Orinoco basin and is separated from its nearest other member of the cupreus Group (Callicebus discolor) in the south by at least 350 km.

Description: Ears and frontal tuft, transverse band or blaze whitish, sharply contrasted with reddish brown crown, the hair bases buffy; sideburns, under-parts, and inner side of limbs reddish; outer surface of thighs, upper arms, upper legs and sides of body buff-agouti; outer side of lower legs and lower part of forearms reddish, sharply contrasted with pale to whitish feet or toes only, and hands or digits only, respectively; proximal one-quarter of tail dark red-brown, distal three-quarters white. Distinguished from Callicebus cupreus and C. discolor by white ears, and pale or whitish digits and toes sharply contrasted with reddish wrists and ankles.

Defler, 2004

Callicebus cupreus ornatus

Distribution: mostly north of the upper Guayabero from the Cordillera Oriental to the Ariari River, but there is an enclave population in the lowlands along the Guayabero River on the south bank, which may extend east of the mouth of the Atrato River down the Guaviare River, but this needs confirmation. The main population extends up the piedmont forest at least to the Upía River. Eastern limits of this subspecies are poorly defined, but except for the Guaviare River, the subspecies probably does not extend beyond the Metica River.

Description: A white band found over the eyes. The white band extends to the point of the ears; the feet and the hands are whitish; also the proximal part of the tail is reddish and the rest is whitish.
