Remarks

• Systematics: Adult female C. cephalotaxus are very similar to those of the Sri Lankan species, C. ophiorrhizae. The two species share some distinct character-states: (i) antennae with seven or eight segments; (ii) multilocular disc pores each primarily with 10 loculi; (iii) anogenital fold with two pairs of anterior margin setae; (iv) anal ring with six anal ring setae; and (v) dorsal and ventral tubular ducts absent, though ventral tubular ducts occasionally present on C. cephalotaxus. However, this species can be separated from C. ophiorrhizae as follows (data for C. ophiorrhizae from Avasthi & Shafee (1991) and Tang (1991) given in brackets): (i) marginal setae slender and straight, with apices either sharp or rather bluntly pointed, or bifurcate or branched (small and simple, with apices pointed); (ii) dorsal setae small, either conical and spinose with apices pointed or slightly cylindrical with apices bluntly rounded (small and cylindrical with apices rounded); (iii) preopercular pores present (absent); (iv) submarginal tubercles present in cephalic region (absent); (v) anogenital fold with 6 lateral margin setae (with 4 lateral margin setae); (vi) ventral setae distributed throughout, slightly denser on submarginal and genital areas, and with submarginal setae fine, in a single row (a few present on median area but submarginal setae absent); (vii) legs with a tibio-tarsal articulation, with or without an articulatory sclerosis; occasionally tibio-tarsal articulation imperfect (with a tibio-tarsal articulation and an articulatory sclerosis); (viii) ventral tubular ducts present or absent (ventral tubular ducts absent); and (ix) body asymmetric and very elongate, narrow anteriorly, broadest at posterior of abdomen (pointed at both ends, broadest at posterior stigmatic clefts). (Cao, et al., 2022)
• Structure: Adult female body asymmetric, very elongate, long and narrow, dorsum with a longitudinal ridge and transverse wrinkles; yellowish-brown to fulvous, mature adult females are slightly darker. Slide-mounted adult female. Mounted specimens asymmetric and very elongate, narrow anteriorly, broadest in posterior abdomen; body 3‒4 times as long as greatest width, 2.7–4.8 mm long, 1.0–1.5 mm wide. Anal cleft approximately 1/10–1/7 of body length. (Cao, et al., 2022)
