Diagnosis

Based on Giupponi & Miranda (2016), this species may be separated from other Charinus in Amazonia and northern South America by means of the following combination of characters: tegument light brown in color; median eyes and median ocular tubercle absent; lateral eyes reduced, pale; tetra- and pentasternum small and rounded; cushion-like gonopods without projections, with internal seminal receptacles; pedipalp almost perpendicular to body, similar to C. ricardoi and Paracharon caecus Hansen, 1921 ; pedipalp coxa with three setae on margin and two setae encircled by round carina; pedipalp tarsus with small basal spine, ca one-quarter length of distal spine; ventral row of setae of cleaning organ with 32 or 33 setae; leg IV basitibia with two pseudo-articles; trichobothrium bt situated in proximal third of basitibia; trichobothrium bc situated closer to sbf than to bf.

Etymology

Patronym honoring Dr Alexandre B. Bonaldo ( Giupponi & Miranda 2016).

Distribution

The distribution of this species is here extended from a single locality in the municipality of Benevides to include the Extractive Reserve in Breves Municipality (Resex Mapuá), a national park in Santarém Municipality (FLONA Tapajós), and the Alter do Chão District, all in the state of Pará, up to 765 km SW of the type locality.

Natural history

All samples from the new localities were female and some small females were carrying egg sacs with fewer eggs than adults, similar to what has been observed with the parthenogenetic Sarax ioanniticus ( Kritscher, 1959) comb. nov. ( Weygoldt 2008), suggesting that C. bonaldoi may also be parthenogenetic.

Remarks

Despite the large distances between populations (Benevides, Breves and Santarém), no morphological differences were found among the specimens. Specimens from the three new localities are similar in the number of pseudo-articles (two) in the basitibia of leg IV, the number of cheliceral teeth (four, excepting the specimen from Satarém [MZSP 67526], with five), the position of the trichobothria on the distitibia of leg IV, the number of spines on the pedipalp, and the shape of the female genitalia. However, the specimens from Breves, Santarém and Alter do Chão are smaller and paler, which may be the due to the stage of development of the specimens (subadults). See Giupponi & Miranda (2016) for further comparison of this species with others in the genus.
