038CBE1BF177FFBE54EDFB48FE2FFE39.taxon	description	(Figure 2, Table 3) Description Female Body straight to curved ventrally after heat fixation. Cuticle annuli 0.9 – 1 μm wide at mid-body. Lateral field consisting of four longitudinal incisures, often areolated. Lip region continuous to slightly offset, 7 – 7.7 μm wide at base, 4.0 – 4.1 μm high, and bearing six or seven transverse annuli. Cephalic framework slightly sclerotized, outer margins extending two or three body annuli posteriorly. Stylet strong, basal knobs laterally directed; the conus almost half of the total stylet length. Dorsal pharyngeal gland orifice located 2.2 – 2.3 μm behind stylet knobs. Median pharyngeal bulb oval, 10 – 11 μm wide; basal bulb pyriform. Hemizonid 2 – 4 annuli anterior to secretoryexcretory pore. Reproductive system didelphic, amphidelphic; spermatheca rounded, with globular sperm. Vagina 12 – 13 μm long, almost 50 – 60 % of the vulval body width. Intestinal fasciculi present in the intestine and inside the post rectal sac which extends into almost the entire tail cavity. Tail cylindrical, finely striated or sometimes smooth terminus, bearing 60 – 67 annuli on ventral side. Hyaline region of tail terminus 5 – 6 μm thick. Phasmids located 25 – 30 μm posterior to anus, located in the posterior half of the tail. Male Not found.	en	Azizi, Kourosh, Eskandari, Ali, Karegar, Akbar, Ghaderi, Reza, Elsen, Sven Van Den, Holterman, Martijn, Helder, Johannes (2022): Analyses of morphological and molecular characteristics of Telotylenchinae from Iran point at the validity of the genera Bitylenchus and Sauertylenchus.

038CBE1BF177FFBE54EDFB48FE2FFE39.taxon	discussion	REMARKS Compared to the original description of B. parvus Allen (1955), the Iranian population has a lower c' ratio (11.5 – 12.1 vs 13 – 16). No other difference in morphological or morphometric diagnostic characters was found. Although this population shows similarity to Sauertylenchus maximus, it can be distinguished from it by a smaller body and stylet (680 – 800 vs 940 – 1062, and 17.7 – 19.6 vs 20 – 24 μm), and the number of tail annuli (60 – 67 vs 25 – 45). This species was recovered from the rhizosphere of alfalfa (Medicago sativa) in Zanjan and Qazvin provinces during the present study.	en	Azizi, Kourosh, Eskandari, Ali, Karegar, Akbar, Ghaderi, Reza, Elsen, Sven Van Den, Holterman, Martijn, Helder, Johannes (2022): Analyses of morphological and molecular characteristics of Telotylenchinae from Iran point at the validity of the genera Bitylenchus and Sauertylenchus.

038CBE1BF17BFFB354EDFBB9FE0EF942.taxon	description	(Figure 4, Table 3) Description Female Body curved ventrally to C-shaped after heat fixation. Cuticle with distinct annuli, 1.5 – 2.3 μm wide at midbody. Lateral field with four longitudinal incisures, outer bands areolated. Lip region offset, hemispherical, 8.0 – 9.0 μm wide at base, 4.0 – 5.0 μm high, and bearing six or seven distinct transverse annuli. Cephalic framework lightly sclerotized, outer margins extending over two or three body annuli. Stylet moderately strong, knobs rounded, slightly directed posteriorly; the conus almost half of the total stylet length. Dorsal pharyngeal gland orifice located 2.0 – 2.1 μm behind stylet knobs. Median pharyngeal bulb oval, 12 – 13 μm wide; basal bulb pyriform, abutting anterior intestine. Reproductive system didelphic, amphidelphic, spermatheca elongated, empty. Vagina 10 μm long, 40 – 60 % of the vulval body diameter. Intestinal fasciculi present throughout intestine and inside post rectal sac which enters into about two-thirds of the tail length. Tail cylindrical with a hemispherical, annulated terminus, bearing 33 – 40 annuli on ventral side. Hyaline portion thickness 6 – 7 μm. Phasmids located 16 – 17 μm posterior to anus, in the anterior half of the tail. Male Not found.	en	Azizi, Kourosh, Eskandari, Ali, Karegar, Akbar, Ghaderi, Reza, Elsen, Sven Van Den, Holterman, Martijn, Helder, Johannes (2022): Analyses of morphological and molecular characteristics of Telotylenchinae from Iran point at the validity of the genera Bitylenchus and Sauertylenchus.

038CBE1BF17BFFB354EDFBB9FE0EF942.taxon	discussion	Remarks Compared to the original description of S. maximus by Allen (1955), the Iranian populations differ by the absence of males. The Iranian populations of S. maximus were recovered from Semnan, Ardabil and West Azerbaijan provinces in the rhizosphere of peach (Prunus persica), grass, hawthorn (Crataegus aronia) and apple (Malus pumila), respectively.	en	Azizi, Kourosh, Eskandari, Ali, Karegar, Akbar, Ghaderi, Reza, Elsen, Sven Van Den, Holterman, Martijn, Helder, Johannes (2022): Analyses of morphological and molecular characteristics of Telotylenchinae from Iran point at the validity of the genera Bitylenchus and Sauertylenchus.
