Caribeacarus Vázquez & Klompen n. gen.
Diagnosis:
1. With 2 pairs of eyes and With's organ membranous and discoid (3 pairs of eyes and With's organ biramous and setiform in Paracarus and Siamacarus).
2. Main opisthosomal segments in adults without setae (with numerous setae in Panchaetes, Salfacarus, and Vanderhammenacarus)
3. Penultimate segment of idiosoma with 3 setae (shared with Neocarus; either 0 or 5 or more in all other genera)
4. Palp tarsus with 7–12 foliate setae (Figs. 44–45) (shared with Phalangiacarus and Siamacarus) 5. Tarsus I sensillum with "crown-like" tip distant from main group of sensory sensilla (Figs. 54–55) (in main group in Neocarus (Fig. 56)). Condition unknown in C. panamensis .
Additional characters. Basal segment of chelicera in male usually with more than 1 setae (Fig. 34) (shared with Siamacarus dalgeri Leclerc (2–5 setae) and Indiacarus (2 setae)); male C. panamensi s n. sp. with 1 seta. Palp trochanter in the adult with 5–8 setae (5 or less in Neocarus). Sternitogenital region between the sternal and genital verrucae with relatively few setae, including 3–4 pairs of stout ribbed setae (usually 4–8 pairs of stout, ribbed setae in Neocarus). N.B. our current understanding of variation in this group is poor, so these characters need to be re-examined when more material becomes available.
Species included:
Caribeacarus armasi n. sp. Type species
C. vanderhammeni (Juvara-Bals & Baltac 1977), new status
C. panamensis n. sp.
Note. The combination in the adults of 3 setae on the penultimate segment of the idiosoma, large numbers of foliate setae on the palp tarsus, and the terminal position of the "crown-like" tip sensillum of tarsi I, appears to provide good support for monophyly of Caribeacarus .
