Paraquimperia tenerrima (von Linstow, 1878) Baylis, 1934 Synonyms: Haplonema aditum Mueller, 1934; Paraquimperia aditum (Mueller, 1934) Moravec, 1966 Description (after Moravec 2013). With characteristics of the genus. Lateral alae up to 0.045 wide at anterior end of body, becoming narrower behind deirids and extending posteriad along length of body. Mouth slightly depressed. Oesophagus opens into intestine through valves. Nerve ring about 0.28 from anterior end. Excretory pore located just posterior to nerve ring. Well developed deirids about 0.56 from anterior end. Males: 4.3–11.2 long; maximum width 0.15–0.28. Entire oesophagus 0.78 long. Tail 0.34–0.44 long. About 30 pairs of oblique muscle bands anterior to cloaca; precloacal sucker absent. Eleven pairs caudal papillae. Spicules equal, somewhat sickle-shaped, 0.250–0.394 long, maximum width 0.021–0.027. Small gubernaculum, 0.063– 0.069 long (Fig. 101 B). Females: 3.6–13.7 long; maximum width 0.11–0.29. Entire oesophagus 0.70–0.80 long. Tail straight, conical, 0.34–0.450 long (Fig. 101 C). Lateral outlets of phasmids located behind mid-length of tail. Vulva in posterior third of body, situated more posteriorly in older than younger females. Vagina long, muscular, directed anteriorly. Eggs thin-walled, 0.060–0.072 x 0.048–0.051.
