Diagnosis

This species is unique due to a combination of following characters: female with dorsal setae reaching setae immediately behind, femur II with three setae (d, v’ and v”), femur III with two setae (d and v’), setae d on genua I–IV reaching tibiae, short setae (about 1⁄6 of podomere length) on femur I, setae l’ and d on femur I nearly located horizontally at same level, dorsal setae c1 and d1 distinctly longer than distance between setae c1–d1 and d1–e1 respectively, idiosomal setae d1 longest, and setae d and l’ on palpal femur heavily spinose.

Etymology

The specific name incorporates the acronym of the “ Centro de Investigación en Biodiversidad y Conservación” (CIByC) at the “Universidad Autónoma del Estado de Morelos ” in recognition of its work on biological conservation.

Intraspecific variation

In the case of Neophyllobius cibyci sp. nov., we observed that leg setation teratologies are relatively rare, but include the following: 1) adult specimens with certain setae in different locations; for example, female right femur I with v” distal to d instead of proximal (CNAC009236), female right femur I with l’ positioned before d (CNAC009234), female left femur I with l’ positioned before d (CNAC009233), female tibiae I with seta dm between v’ and v” (CNAC009231 and CNAC009235) instead of distal, female right tibia I with dm between v’ and v” (CNAC009232) instead of distal, and male right tibia I with l’p distal to l”p instead of proximal (CNAC009238); 2) female specimens without setae on left or right legs, for example left femur I without l’ (CIUM), left femur I without v” (CNAC009236), and left tibia I without v” (CNAC009236 and CIUM).

Remarks

Neophyllobius cibyci sp. nov. resembles N. farrieri De Leon, 1958 collected on “Spanish moss” (probably Tillandsia usneoides ) in Oaxaca, Mexico. In both species, dorsal setae on genua I–IV are very long, extending beyond the tip of the tarsus, setae on femur I are short (about 1⁄6 of podomere length), and setae l’ and d on femur I are nearly located at the same level. These species can be differentiated by the following characters: in N. cibyci sp. nov., dorsal setae c1 and d1 are distinctly longer than the distance between setae c1–d1 and d1–e1 respectively, setae d1 are the longest of the dorsal setae, and setae d and l’ on palpal femur are heavily spinose. In N. farrieri , the lengths of dorsal setae c1 and d1 are the same as the distance between setae c1–d1 and d1–e1 respectively; setae e1 are the longest of the dorsal setae, and setae d and l’ on palpal femur are weakly spinose.

Neophyllobius cibyci sp. nov. includes at least three postembryonic instars (larva, protonymph and adult). We found only one nymphal instar (protonymph) which resembles the female type proposed by Bolland (2001).

Ecology

Neophyllobius cibyci sp. nov. was the most abundant camerobiid species with 17 specimens, most of which (76.5%) were collected in dry season (March and April). This species is deemed to be an inhabitant of the tree canopy because most specimens (94%) were collected on epiphytic bromeliads at 2.8 m (± 0.4) and only one female specimen (CNAC009237) was found on soil litter. Neophyllobius cibyci sp. nov. was found in low numbers, usually one specimen per sample, except for two samples which had two specimens each. The closely resembling species, N. farrieri , also inhabits epiphytic bromeliads of the genus Tillandsia .

Distribution

This species is only known from San Andrés de la Cal, Morelos, Mexico. The type locality of N. cibyci sp. nov. is about 440 km as the crow flies from the known distribution of N. farrieri (Puenta [sic.] de Nejapa, Oaxaca, Mexico).

Setal homology among Neophyllobius cibyci sp. nov. instars

The collection of different instars provides material for study and suggests the ontogenetic development pattern of gnathosoma, idiosoma and leg chaetotaxy.Although, Grandjean’s idiosomal and leg chaetotaxy systems were previously applied to camerobiid mites ( Kethley 1990; Fan & Walter 2011), this is the first study of complete chaetotaxy (on gnathosoma, idiosoma and legs) involving three different instars (larva, protonymph and adult) of a camerobiid mite species. Swift’s (2001) study of leg chaetotaxy of Caligonellidae (Raphignathina: Raphignathoidea ), included one larva and one adult female of an undetermined species of Neophyllobius . We found only one nymphal instar (protonymph); for this reason and because the presence of deutonymph is questionable in Neophyllobius , we prefer not to hypothesise the presence of setae in this particular instar (deutonymph).

There are different concepts about the leg chaetotaxy. Fundamental setae are those present when the appendages in question are first formed, that is on legs I–III in the larva or on leg IV in the protonymph. Accessory setae are any which are formed during subsequent moults ( Grandjean 1941; Norton 1977; Swift 2001). Setal priority for each podomere refers to a list of setal organs that appear at the beginning of ontogeny (fundamental setae) and have greater priority, or force, than organs than develop later (accessory setae), which suggests that these setal organs are less susceptible to evolutionary regression ( Norton 1977; Swift 2001). Setae of equal priority are listed together within parentheses as proposed by Norton (1977).

GNATHOSOMA. Larvae have Or1 and Or2. Setal pattern on palps is consistent across larva, protonymph and adults, except that dorsal seta (d) on femur do not appear until the protonymphal instar; count of setae from palp coxa to tarsus: 1 (elcp), 0, 2, 1, 3 + 1 claw, 4 + ω. Setal pair m on subcapitulum do not appear until the protonymphal instar.

IDIOSOMA. The dorsal chaetotaxy in larvae includes 14 setal pairs: vi, ve, sci, sce, c1, c2, d1, d2, e1, e2, f1, f2, h1 and h2 ( Fig. 2E ). Setal pair pdx appears in protonymph ( Fig. 2C ). The ventral chaetotaxy in larvae includes six setal pairs: 1a, 1b, 3a, ps1, ps2 and ps3 ( Fig. 2F ). Setal pairs 1c, 2c, 3b, 3c and 4a are added in protonymph ( Fig. 2D ). Setal pairs 4b and 4c are added in adults ( Figs 1D , 2B ). Setal pair ag is present only in adult females ( Fig. 1D ).

LEGS ( Table 2). Setae v are absent on trochanters I–III in larva ( Fig. 3 M–O), and do not appear until the protonymphal instar ( Fig. 3 I–K). Seta v on trochanter IV does not appear until adulthood ( Fig. 3D, H ). Femora I–II of the larva with setae v” and d ( Fig. 3 M–N), femur III of the larva ( Fig. 3O ) and femur IV of the protonymph ( Fig. 3L ) only with seta d. Seta l’ is added on femur I of the protonymph ( Fig. 3I ). Setae v’ on femora I–III ( Fig. 3 A–C, E–G), and l” on femur IV ( Fig. 3D, H ) are added in adults. The setal priorities on femora I and II for Neophyllobius cibyci sp. nov. are: (d, v”), l’, v’. Priorities on femora III and IV are: d, l”, v’. Genua I–II in all instars with seta d and κ ( Fig. 3 A–B, E–F, I–J, M–N), and genu III only with d ( Fig. 3C, G, K, O ). Genu IV of the protonymph and adults only with seta d ( Fig. 3D, H, L ).

Tibiae I–III of larva with setae dm, l’, l” and φ ( Fig. 3 M–O). Tibia IV of the protonymph with setae dp, v’m, l” and φ ( Fig. 3L ); dp and l”p are added to tibiae I–III ( Fig. 3 I–K) of the protonymph. Seta v’m is added to tibia I ( Fig. 3I ) of the protonymph. Setae l’p, and d are added to tibiae I–II of adults ( Fig. 3 A–B, E–F). Seta v”m appears only on tibiae I of adults ( Fig. 3A, E ). Setae l’p and v’m are added to tibia III of adults ( Fig. 3C, G ). Setae l’, dp, l”p and d are added to tibia IV of adults ( Fig. 3D, H ). Tibia I of males with φ 2 ( Fig. 3E ). The setal priorities for tibiae I and II in Neophyllobius cibyci sp. nov., are: (dm, l’, l”), (dp, l”p, v’m), (d, l’p, v”m). Priorities on tibiae III and IV are similar except v”m is not formed.

Tarsi I–II of the larva with vs’, (tc), (p), (u) and ω ( Fig. 4 M–N), tarsus III with vs’, (tc), (u) and ω ( Fig. 4O ). In tarsi I–II of protonymph, setal pair a is added ( Fig. 4 I–J). Seta vs’ is lost on tarsi I and III of protonymph but vs” appears ( Fig. 4I, K ). Tarsus IV of the protonymph with vs’, (tc) and (u) ( Fig. 4L ). Setae vs’ reappears in tarsi I and III of adults ( Fig. 4A, C, E, G ). Seta vs” appears on tarsi II and IV ( Fig. 4B, D, F, H ). Setal pair p is added in tarsus IV of the adults ( Fig. 4D, H ). Tarsi III–IV of males with ω ( Fig. 4 G–H). The setal priorities for tarsi I and II are: (tc’, tc”, u’, u”, vs’, p’, p”), (a’, a”, vs”). Priorities on tarsi III and IV are: (tc’, tc”, u’, u”, vs’), (p’, p”, vs”).
