|Distribution||Brazil (Mato Grosso, S Para), Bolivia (Santa Cruz, Beni), Paraguay (fide Paul Smith, pers. comm., 27 Apr 2014)|
Type locality: Bastos Farm on Río Alegre, Headwaters of Río Guaporé, western Mato Grosso, Brazil.
|Types||Holotype: CM (Carnegie Museum) P-962|
|Diagnosis||Diagnosis (genus). The species in this genus is characterized by (1) frontoparietals, two, (2) supraciliaries, four, (3) supraoculars, four, (4) prefrontal contact, absent or rare, (5) parietal contact, present, (6) rows of nuchals, one, (7) dorsals + ventrals, 136–141, (8) total lamellae, 147–154, (9) a dark middorsal stripe, present, (10) dark dorsolateral stripes, present, (11) a dark lateral stripe, present, and (12) dark ventral striping, absent. The maximum body size in the single included species is 98 mm SVL (Dunn 1936; Table 2). Besides the unusual dark middorsal stripe (not visible in all specimens), this genus also differs from others in having exceptionally short limbs and small hands and feet. In its low number of total lamellae (147–154), it differs from all other genera (> 157 total lamellae), although this character was not scored in Exila, Maracaiba, and Orosaura. However, Manciola differs from those three genera and Capitellum, Copeoglossum (except C. arajara), Mabuya, and Psychosaura in having pale (versus dark) palms and soles. From Exila, Notomabuya, and Panopa, Manciola differs in having two frontoparietals (versus one fused frontoparietal in those other genera). In having four supraoculars, Manciola is separated from two genera with three supraoculars: Aspronema (rarely four) and Mabuya (rarely two or four). The presence of a single nuchal row separates this genus from Exila and Panopa (2–5 nuchal rows) and from most Spondylurus (usually 2–3 rows, rarely one). The presence of contact between the parietals separates this genus from Copeoglossum. It differs from Alinea by having fewer finger-IV + toe-IV lamellae (21–22 versus 28–36), having dark lateral stripes, and lacking ventral striping HEDGES & CONN 2012].|
|Comment||Type Species: Mabuya guaporicola Dunn, 1936:549. is the type species of the genus Manciola HEDGES & CONN 2012.|
Phylogenetics. The molecular phylogeny (Fig. 5 in HEDGES & CONN 2012) does not clearly establish the relationship of this genus to others.
|Etymology||The generic name (Manciola) is a feminine, Latin, noun meaning small hand, in reference to the relatively small hands and feet in these skinks.|
