Diagnosis (female).
Body fusiform; prodorsal shield with a broad frontal lobe, median, admedian, and submedian lines present, formed by discontinuous granules, and many granules; legs with 4-rayed simple tarsal empodium, and knobbed tarsal solenidion; opisthosoma dorsally with elliptical microtubercles, while ventrally with elliptical to linear microtubercles; female genital coverflap with many granules at base and 11 striae.

Calepitrimerus huayanlingense
sp. nov.
AD, prodorsal shield; CG, female coxigenital area; em, empodium; IG, female internal genitalia; L1, leg І; L2, leg II; DM, dorsal view of telosoma; VM, ventral view of telosoma. Scale bar: 15 μm for AD, CG, DM, IG, L1, L2, VM; 3 μm for em.
Relation to the host plant.
Vagrant on lower leaf surface with no apparent symptom to the host.
Etymology.
The specific designation
huayanlingense
is derived from the name of location, where the new species was collected, adding a postfix -
ense
; neuter in gender.
Differential diagnosis.
We compared the new species with three
Calepitrimersu
mites because they all infest
Ficus
sp. (Moraceae)
. The new species can be differentiated from
C. fici
Wei, 2004
(infest
Ficus hirta
) by median, admedian, and submedian lines formed by discontinuous granules (median, admedian, and submedian lines present in
C. fici
), setae
h1
present (setae
h1
absent in
C. fici
), and empodium 4-rayed (empodium 5-rayed in
C. fici
). The new species can also be differentiated from
C. asperrimae
Mohanasundaram,1982
(infest
Ficus exasperata
), and
C. hispidis
Mondal & Chakrabarti, 1983
(infest
Ficus hispida
) by median, admedian, and submedian lines formed by discontinuous granules (prodorsal shield with lines granules in
C. asperrimae
; median, admedian, and submedian lines not formed by granules in
C. hispidis
), dorsal annuli with microtubercles (dorsal annuli smooth in
C. asperrimae
and
C. hispidis
), and female genital coverflap with one row of striae (female genital coverflap with two rows of striaes in
C. asperrimae
and
C. hispidis
).
