Description

Puparium: Body ( Figs. 4a View FIGURE 4 , 5a View FIGURE 5 ) asymmetrical and elongate-banana shaped (2.33–3.67 mm long, 1.00– 1.63mm wide, generally widest around abdominal segment II), with one side more enlarged and curved than the other, which is more planar. Dorsum with 9 pairs of lateral rays on the dorsum, running mesad from the puparial margin. These rays are significantly wider in this species compared to other species in the genus (approximately 2–3 times wider).

On the sub-mesial plane of the dorsum are 4 pairs of compound pores; subequal in size (approximately 17 µm in diameter); each containing a short, stout central process ( Figs. 4c View FIGURE 4 , 5c View FIGURE 5 ). The pores are located thusly; 1 cephalothoracic pair, located between the 1st and 2nd pairs of rays, and on the sub-mesial plane. 2 pairs on the central latitudes of abdominal segments III and IV, and on the sub-mesial plane. The final pair of compound pores are found on abdominal segment VII, behind the VO, on the anterior edge of the 9th pair of rays, and close to the puparial margin. A furrow runs to the puparial margin from each posterior pore, and beside the anterior edge of the 9th pair of rays ( Fig. 4e View FIGURE 4 ).

The margin is planar, but with submarginal folds producing a crenulated submarginal layer with well-defined teeth, and an additional layer of folds of less well-defined teeth, appearing as collars for the dentate folds ( Figs 4d View FIGURE 4 , 5b View FIGURE 5 ). The submargin of rays 1, 2, 3, 4, 5, 6, 7, and 8, however, have combs of 4 teeth that are finer than the teeth along the rest of the margin, with the middle 2 teeth being finer than the 2 outer teeth ( Figs 4d View FIGURE 4 , 5b View FIGURE 5 ). The margin where the compound pore furrow on abdominal segment VIII terminates is always slightly indented ( Fig. 4e View FIGURE 4 ).

VO ( Figs 4b View FIGURE 4 , 5d View FIGURE 5 ) elongate roundly-deltoid (approximately 0.13mm long; approximately 1.8 times longer than wide at the base), with a reticulated floor. Inset from caudal margin by approximately 5–6 times its own length. Operculum broadly rounded-oblong, approximately 1.5 times wider than long, and covering approximately 3/5 of the lingula. Lingula inserted and elongate subcordate, the posterior tip at a narrow, acute angle, taking up roughly a third of the area of the VO.

Adults. Unknown. No adults that could be linked to these specimens were available for study.

Etymology. The species epithet, brianeno , a noun in apposition, is named after the seminal musician, composer, producer, visual artist, and theorist, Brian Peter George St John Baptiste de la Salle Eno, who has pioneered, and played an important role in ambient, rock, pop, and electronic music.

Comments. The species which C. brianeno sp. n. most closely resembles is C. varus . Both species display asymmetry in their puparial shape, and have similar, small compound pores. Uniquely, however, the compound pores of C. brianeno are always paired, despite the asymmetrical shape of the puparial case, while in C. varus the compound pores are only found on one side of the puparium. Additionally, the final pair of pores in C. brianeno are closer to the puparial margin, more on the sub-mesial plane than the final pore of C. varus , which is positioned closer to the VO, and more on the mesial plane. The VO of C. brianeno is more elongate than the VO of C. varus , with a lingula that is smaller than the lingula of C. varus ; the former lingula only taking up roughly a third of the area of the VO and the latter lingula taking up over half the area of the VO. Finally, the mesad running rays of C. brianeno are significantly wider than the rays of C. varus .
