Description of Metateratocephalus bialowieziensis sp. n. (Nematoda, Metateratocephalidae). Holova-
chov O. V. — A new species Metateratocephalus bialowieziensis Holovachov, sp. n. from Poland is
described. It diffres from other species of the genus by dorsally arcuate body, linger rectum and by
combination of morphometric characters.

The genus Metateratocephalus Eroshenko, 1973 includes three valid species: M. crassidens (de Man,
1880) Eroshenko, 1973, M. deckonincki Andrassy, 1984 and M. gracilicaudatus Andrassy, 1985. A population
of Metateratocephalus from the Sphagnum-moss from Bialowiezski Park Narodowy from Poland was found to
be different from all other species of the genus in a number of characters and is described here as a new
species. Specimens were available as permanent glycerine sides due to the courtesy of Dr. G. Winiszewska,
whose kindness is greatly acknowledged.
Metateratocephalus bialowieziensis Holovachov, sp. n.
Fema l e. Body cylindrical, gradually narrowing anteriorly on the pharyngeal regi-
on and posteriorly on tail. Body when heat relaxed strongly curved dorsad. Cuticle
when seen under the light microscope without distinct annulation but with transverse
rows of very fine punctations. Lateral field indistinct. Somatic setae not seen. True
deirids and phasmids absent. Labial region strongly offset, crown-shaped with U-shaped
sclerotization under the light microscope, with six leaf-shaped lips. Each subdorsal and
subventral lips bearing two setae while lateral lips bearing only one setae each. Amphids
large, circular with small tube-like aperture, located posteriorly to stoma base. Stoma
funnel-shaped, consist of two sections: wide anterior with strongly sclerotized bar-
shaped rhabdia, and funnel-shaped posterior with weakly sclerotized rhabdia. Pharynx
cylindrical, with distinct differentiation between corpus and isthmus. Corpus cylindri-
cal, isthmus cylindrical and somewhat narrower than corpus. Basal bulb oval, with
strongly developed valvular apparatus. Pharyngeal glands indistinct. Dorsal gland orifice
opening into the pharyngeal lumen somewhat posterior to stoma base. Radial tubules
present. Secretory-excretory system well developed, excretory gland is located ventral
to isthmus, excretory pore posterior to nerve ring. Female reproductive system didelph-
ic, amphidelphic, ovary branches antidromously reflexed. Vagina short and straight.
Spermatheca absent. No sperm in the genital tubes. Rectum straight, longer than the
anal body diameter. A pair of caudal ventrosublateral setae is situated about 1.5 anal

body diametrs posteriorly to anal opening. Tail plump, cylindro-conoid, strongly curved
dorsad. Punctation on the tail very weak. Caudal glands absent.
Ma l e. Not found.
D i a gno s i s. Small nematode with dorsally arcuate body, weak cuticular puncta-
tion, long rectum, caudal setae located posteriorly to anus, plump cylindro-conoid dor-
sally curved tail.
R e l a t i o n s h i p s. M. bialowieziensis differs from all species of Metateratocephalus
by the dorsally arcuate body (versus straight) and longer rectum (R/ABD 2.0–2.5 ver-
sus 1.0–1.6, rectum length 17–23 mkm versus 7–12 mkm). It further differs from
M. crassidens (sensu Eroshenko, 1973; Zell, 1993; Karegar et al., 1997) (syn. M. typi-
cus Eroshenko, 1973) in weak lateral punctation (versus prominent); from M. crassi-
dens (apud Swart et al., 1989) in relatively shorter (c = 9.1–11.2 versus 6.4–8.0) and
plump tail (versus with filliform terminal part), caudal setae located 1.5 ABD posteri-
orly to anus (versus at anus level); from M. deconincki (syn. M crassidens apud De
Coninck, 1935) in more anterior amphid location (Amphid/LRD = 1.0–1.3 versus 3),
acute tail terminus (versus mucronate); from M. gracilicaudatus in absolutely (36.5–
43 mkm versus 56–62 mkm) and relatively (c' = 4.4–5.2 versus 7–8) shorter and
plump tail (versus with filliform terminal part), weak lateral punctation (versus promi-
nent) and in more anterior amphid location (Amphid/LRD = 1.0–1.3 versus 1.5–1.7).

Typ e l o c a l i t y. Holotype and twelve paratype females, Poland, Bialowiezski Park
Narodowy, Puszcza Bialowiezska, department N 513, Sphagnum-mosses, 22.10.1985 (Wi-
niszewska).
T yp e s p e c imen s. Holotype and four paratypes in the nematodes collection of
