| H. Byrne et al. 2016 | Hershkovitz’s [5] review contains detailed descriptions of the dental, cranial and post-cranial characters of the titi species recognized at the time, and presents summaries of the key characteristics of his mod- estus (included here in the donacophilus group), donaco- philus (Fig. 7) and moloch (Fig. 8) groups. Groves’ [16] taxonomy, with some exceptions, followed that of Hersh- kovitz, and the distinguishing features he provided, and that we record here, are from Hershkovitz’s comprehen- sive 1990 review [5].
Groves [16] (p. 171) summarized the modestus group as follows: “Externally resembles the moloch group, but cra- nially primitive according to Hershkovitz [5], with an elongate, low-slung cranium, very small cranial capacity, only 20 % of greatest skull length, and short occiput, con- dylobasal length averaging 86 % of greatest skull length. Median pterygoids very large; mandibular angle large. Postcranial skeleton unknown; chromosomes unknown”. Characteristics of species of the donacophilus group (donacophilus, pallescens, olallae and oenanthe) were summarized as follows by Groves [16] (p. 171): “Cranial capacity 21 − 25 % of greatest skull length, condylobasal length 81 − 84 % of greatest skull length. Arm (radius plus humerus) 52 − 58 % of trunk length, leg (tibia plus femur) 71 − 78 %. Chromosomes 2n = 50”. Characteristics of the moloch group, including the spe- cies cinerascens, hoffmannsi, baptista, moloch, brunneus, cupreus (synonyms caligatus, discolor, toppini, anddubius), and ornatus, were summarized by Groves [16] (p. 172 − 173) as follows: “Cranial capacity 26 − 29 % of greatest skull length; condylobasal length 78− 82 %. Forelimb (known only for C. cupreus) 53-61 % of trunk length, hindlimb 72 − 81 %. Chromosomes 2n = 48 (C. moloch, C. brunneus) or 46 (C. cupreus, C. ornatus)”. The groups began to diversify c. 4.39 Ma, in the Early Pliocene. |
