(holotype, UMMZ 101121), (D) _guttilatus_ (UIMNH 55520), (E) _marnockii_ (TCWC 4782), and (F) _longipes_ (TCWC 12179). All x6.5.] [Illustration: FIG. 2: Palmar views of hands of two species of the western complex of _Syrrhophus_. _pipilans_ (left, KU 58908, x6) and _teretistes_ (center, KU 75269, and right, KU 75263, respectively, x9).] In _S. cystignathoides_ and _leprus_, the first finger is longer than the second, and the first two fingers are equal in length in _guttilatus_ and _marnockii_. In the other species the first finger is shorter than the second. Supernumerary tubercles are well developed on the plantar surfaces in all species, except _S. guttilatus_, in which they are poorly defined (Fig. 3). The relative sizes of the metatarsal tubercles has been used in the classification of the species and species groups of _Syrrhophus_. The metatarsal tubercles are similar in all species of the eastern complex (including _rubrimaculatus_); the outer tubercle is always about one-half the size of the ovoid inner metatarsal tubercle. In the _leprus_ group the outer tubercle is conical and compressed. The metatarsal tubercles of _pipilans_ are about the same size, or the outer is slightly smaller than the inner. In the _modestus_ group the outer metatarsal tubercle is about one-third the size of the inner.
