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.

Female (n = 11, dorsal view): Body fusiform ( Figure 6A View FIGURE 6 ), 218 (198–218) long, 70 (67–70) wide; light yellow in colour. Gnathosoma 17 (16–19) long, projecting obliquely downwards, cheliceral stylets 19 (17–19), pedipalp coxal seta (ep) 3 (2–3), dorsal pedipalp genual setae (d) 6 (5–6), palp tarsal ventral setae (v) absent. Prodorsal shield 53 (51–58), including the frontal lobe, 70 (65–70) wide, frontal lobe broad; median, admedian, and submedian lines present, formed by discontinuous granules; many granules present on whole prodorsal shield ( Figures 5 View FIGURE 5 AD, 6B). Scapular tubercles ahead of rear shield margin, setae sc 7 (6–7), 24 (24–25) apart, projecting centered. Coxigenital region ( Figures 5 View FIGURE 5 CG, 6C) with 10 (10–12) semiannuli between coxae and genitalia, with microtubercles; coxal plates with granules, anterolateral setae on coxisternum І (1b) 9 (9–10), 14 (13–14) apart; proximal setae on coxisternum І (1a) 15 (15–17), 9* apart; proximal setae on coxisternum ІІ (2a) 34 (32–36), 29 (28–29) apart. Prosternal apodeme 6 (6–8). Leg І ( Figure 5L View FIGURE 5 1 View FIGURE 1 ) 33 (33–35), femur 10 (10–11), basiventral femoral setae (bv) 11 (10–11); genu 5*, antaxial genual setae (l'') 21 (21–23); tibia 8 (8–9), paraxial tibial setae (l') 7 (6–7), located at center; tarsus 6*, paraxial fastigial tarsal setae ft’ 21 (19–21), antaxial fastigial tarsal setae ft’’ 22 (21–22), setae u' 6 (5–6); tarsal empodium (em) 5 (5–6), simple, 4-rayed, tarsal solenidion (ω) 6 (5–6), knobbed. Leg ІІ ( Figure 5L View FIGURE 5 2 View FIGURE 2 ) 28 (28–30), femur 9 (9–10), basiventral femoral setae (bv) 11 (10–11); genu 5 (4–5), antaxial genual setae (l'') 9 (7–9); tibia 6*; tarsus 6*, paraxial fastigial tarsal setae ft’ 5 (5–6), antaxial fastigial tarsal setae ft’’ 22 (20–22), setae u' 5 (4–5); tarsal empodium (em) 6 (5–6), simple, 4-rayed, tarsal solenidion (ω) 6*, knobbed. Opisthosoma dorsally with 44 (43–44) semiannuli, with elliptical microtubercles, with three ridges, middorsal ridge ended on 27–28 annuli, in a broad furrow ( Figure 6A View FIGURE 6 ); ventrally with 71 (70–73) semiannuli, with elliptical to linear microtubercles. Setae c2 27 (24–27), on ventral semiannulus 11 (11–12), 56 (51–56) apart; setae d 45 (45–50), on ventral semiannulus 26 (25–26), 35 (33–35) apart; setae e 23 (22–25), on ventral semiannulus 48 (46–48), 14 (14–15) apart; setae f 31 (25–31), 27 (25–27) apart, on 6th ventral semiannulus from rear; setae h1 3 (2–3), setae h2 78 (65–78). Female genitalia 19 (17–19), 25 (23–25) wide, coverflap with many granules at base and 11 striae, setae 3a 30 (25–30), 18 (17–18) apart. Internal genitalia: spermathecae ovoid, oriented posterolaterad; spermathecal tubes relatively short; transverse genital apodeme trapezoidal ( Figures 5 View FIGURE 5 IG, 6D).

Male: Not found.

Type material. Holotype, female ( NJAUZJ272.1 ), found on Ficus erecta Thunb. (Moraceae) , Huayanling , Wenzhou city, Zhejiang province, China, 23°07′12″N, 112°29′46″E, elevation 500 m, 13 August 2015, coll. Yue Yin GoogleMaps . Paratypes, 10 females on 10 slides (NJAUZJ272.2–11), from F. erecta Thunb. (Moraceae) , same details as holotype.

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 ).
