Trachelomonas

Trachelomonas Ehrenberg (ref. ID; 4965), Ehrenberg, 1833 emend. Deflandre, 1926 (ref. ID; 4950) or Deflandre (ref. ID; 4966)

Order Euglenales (ref. ID; 4826)
Family Euglenaceae (ref. ID; 4966)

[ref. ID; 1618]
With a lorica which often possesses numerous spines; sometimes yellowish to dark brown, composed of ferric hydroxide impregnated with a brown manganic compound; a single long flagellum protrudes from the anterior aperture, the rim of which is frequently thickened to form a collar; chromatophores either two curved plates or numerous discs; paramylum bodies small grains; a stigma and pyrenoid; multiplication by fission, one daughter individual retains the lorica and flagellum, while the other escapes and forms a new one; cysts common; fresh water. (ref. ID; 1618)

[ref. ID; 3490]
The cell carrys a lorica characteristic to species and has a single long flagellum, a conspicuous eye-spot and a number of discoid chloroplasts. The lorica with a pore from which a flagellum projects, is variable in shape, size, colour and surface ornamentation. The colour of the lorica is changeable pale yellow to dark brown according to amounts of iron salts. (ref. ID; 3490)

[ref. ID; 4965]
The morphology of the lorica is used as a taxonomical character to separate species, varieties and formae. Different types of envelope ornamentations, like punctuations, spines, scrobiculations, warts, tubercles, ridges, etc. have been described in numerous works. (e.g. Deflandre 1926; Huber-Pestalozzi 1955; Conforti & Tell 1986). (ref. ID; 4965)

Trachelomonas allorgei var. brevicollis Conforti & Ruiz, 2001 (ref. ID; 3550 original paper)

Diagnosis

Varietas different a typo parvo longituidine coli, 2-2.5 um longa, 4.5-5 um lata. (ref. ID; 3550)

Comments

This variety presented the same characteristics as the variety type, the only difference being the shorter length of the neck (2-2.5x4.5-5 um), irregular at the distal end. Posterior end narrowed into a long conical cauda (10-11 um long). Envelope yellowish to deep brown, irregular and strongly punctuated (68-75/100 um2). The studied lorica showed numerous bacteria adhered on this surface. These organisms could be considered T. fusiformis Stokes, but in this taxon the cauda is not clearly differentiated from the body as it is in the observed specimens. (ref. ID; 3550)

Type locality

In Chunam lacu, Keung Nam, Corea. (ref. ID; 3550)

Measurements

Trachelomonas armata (Ehrenberg) (ref. ID; 3490) or (Ehrenberg) Stein (ref. ID; 3517, 3550, 4950)

Descriptions

The lorica is elliptical with a low collar and a number of long curved spines on the posterior region. The typical form is smooth on the surface of the lorica, but those of the specimens examined in the present work are spiniferous on the entire or partial surface. According to Skvortzow (1925), forms spiniferous entirely seem to belong to var. plancionica Skvortzow, ones partially in the anterior half to var. ovata Skvortzow and those also partially in the anterior and posterior regions to var. steini Lemmermann. (ref. ID; 3490)

Measurements

The size is comparatively constant, being 40-42 um in length and 32-34 um in transdiameter. (ref. ID; 3490)

Trachelomonas armata var. armata f. inevoluta Defl. (ref. ID; 4966)

Descriptions

The organisms observed from Colombian Amazonia were smaller, 27-30 um long, 24-27 um diam., than those described by Tell & Conforti (1986), 38x31 um. Lorica widely cylindrical or quadrangular with broad poles and more or less parallel sides. Membrane fine and sparsely punctuate. It can be observed a group of areolae (1-2 um diam.), resembling the bases of spines, around the posterior end. Pore with an annular thickening. It is necessary to clarify that the areolae do not resemble broken spines, we observed this character many times and the cut is never so "clean" nor in all spines. (ref. ID; 4966)

Trachelomonas armata var. gordeievi Skv. (ref. ID; 4950), gordeievii Skv. (ref. ID; 4966)

Descriptions

Lorica 37-40 um long, 28-31 um diam., broadly ellipsoidal or ovoid with anterior end narrower than the posterior one. Membrane yellowish to brownish apparently smooth, ornamented with conical spines (1-1.5 um long) at the anterior end and a crown of very long spines at the posterior one (15-18 um long). Pore surrounded by 10-12 conical spines (1.5-2.5 um long). This variety has been originally described with S.E.M. by Coute and Therezien (1985). (ref. ID; 4966)

Membrane yellowish sometimes colourless, finely punctuate (120-150/100 um2) and with conical spines (1.8-2x0.3-0.5 um) regularly distributed (6-10/100 um2). Posterior end ornamented with a crown of very long curved spines (12-14x2-3 um). This variety was already described with S.E.M. by Coute & Iltis (1981) and Coute & Therezien (1985). (ref. ID; 4966)

Trachelomonas armata var. nana Balech f. spinosa (ref. ID; 4966 original paper)

Descriptions

Lorica 29-32 um long, 25-27 um broad, ellipsoid or slightly ovoid with rounded ends, anterior end narrower than the posterior one. Pore surrounded by a crown of 8-12 short conical spines (1-1.5 um long). Membrane yellowish to deep brown, with closely distributed punctuations and very scattered (13-15/100 um2) short conical spines (0.8-1 um long). Posterior end ornamented with a crown of well developed (10-12 um long), curved, more or less convergent conical spines. Balech in his description of var. nana, reported "ovoid with flattened poles, specially the posterior one..." and this fact is shown in his photo 184, although in the fig.65, the anterior pole is very much narrower than the posterior one. This forma presents the characteristics of the type variety, the only difference being the short conical spines that ornamented the pore and the body of the lorica. Balech's variety shows only a posterior crown of long spines. (ref. ID; 4966)

Trachelomonas armata var. setosa Drez. (ref. ID; 4966)

Posterior end ornamented with a crown of long spines (6-8 um), straight or slightly divergent. Pore without collar surrounded by short spines at the distal end. This variety could be considered T. superba var. swirenkiana, but this taxon the spines are not regularly distributed on the body surface, as in the specimen shown. Moreover, the length/breadth ratio in our specimens is closer to that in T. armata var. setosa than in T. superba var. swirenkiana. (ref. ID; 4966)

Trachelomonas bernardinensis W. Vischer emend. Defl. (ref. ID; 4950, 4966)

Descriptions

Lorica 35-37 um long, 18-20 um broad, elongate-ellipsoid with the sides usually regularly arched, but sometimes slightly attenuated towards the anterior end. Membrane deep brown sparsely punctuate with numerous adhered particles on its surface. Pore surrounded by a wide conical collar (3-4x5.5 um) with spines or crenulate at the tip. Posterior end gradually tapering to a conical cauda. (ref. ID; 4966)

Comments

Deflandre (1926) described this taxon as showing a strongly scrobiculated membrane. Within the material examined, we found a pool of specimens, with a punctuated membrane that presented variable quantities of agglutinated particles. Perhaps, this material could appear as scrobiculations in light microscope. (ref. ID; 4966)

Descriptions

The lorica is pod-shaped with a cylindrical collar and blunt posterior end, and light or dark brown in colour. (ref. ID; 3490)

Comments

The form studied in the present work is obviously identified with Skvortzow's T. cucurbita var. ovata, but ovata had been previously used for varieties of other species, therefore, the author has given the new name to the invalid one. (ref. ID; 3490)

Descriptions

Lorica 54-59 um long, 16-20 um broad, spindle-shaped, sides regularly arched. Anterior end narrowed into a cylindrical neck (8-9x5-6 um). Posterior end gradually tapering towards a subconical tail (12-13x5-6 um). Membrane yellowish to deep brown, punctuated and ornamented with conical spines arranged in definite areas. Around the distal end of the neck there is a crown of 5-6 robust spines (4-5x1.5-2 um). The body presents conical spines of variable length: the longer ones are located on the ends and the smaller (1.5-2x0.5-1 um) spines are distributed scattered (7-10/100 um2) on the central part of the body. The tail is like a truncated cone with 4 robust spines (4-5x1-1.5 um) on the free end. (ref. ID; 4966)

Comments

From comparison with other descriptions of this species in S.E.M., we can conclude that the number punctuations seems to be very variable: from 60-70/100 um2 (Tell & Coute 1980) or 80-85/100 um2 (Conforti and Tell 1986), to very scattered, as we observed in our materials (20-40/100 um2). (ref. ID; 4966)

Trachelomonas duquei (ref. ID; 4966 original paper)

Descriptions

Lorica 36-37 um long, 31-33 um wide, broadly ovate with regularly arched sides. Anterior and posterior ends obtusely rounded to flattened. Membrane brown, strongly punctuated (82-90/100 um2) and ornamented with conical spines (1.5-2.5 um long), irregularly distributed (11-15/100 um2). The punctuations are so large (0.4-2 um diam.) and variable in shape, that this feature suggests that some of the might be the result of fusions. (ref. ID; 4966)

Comments

This newly established species resembles T. allia var. obesa Balech (30-32x23-25 um), but it differs mainly in its larger dimensions, the anterior and posterior end flattened, the clearly arched sides and the strongly punctuated membrane. The shape of our specimens does not resemble T. bacillifera Playf.: sides are more curved in the latter and the length/breadth ratio is also different. (ref. ID; 4966)

    Comments

    T. rugulosa var. meandrina Conr., T. vermiculosa var. vermiculosa Palmer, and T. vermiculosa var. tiszae Szab. resemble lorica types b and c, but they differ in their spherical shape and in the bigger dimensions of the envelopes. Among the taxa with ellipsoid lorica, T. irregularis Svir. could coincident with the ornamentation type a or b, but the cell differs in the three chromatophores without pyrenoids (Balech 1944). T. felix Skvortsov, T. nigra Swir., and T. pseudofelix Defl. (= T. intermedia var. manchurica Skvortsov and T. intermedia var. pekinensis Skvortsov) present ornamentation that are similar to the type c. The two latter species also showed a type c like annular thickening. However, all three are bigger than our specimens. T. xenosoma Middel. is an other example of a species with spherical or ovoid lorica and very variable ornamentation, but it differs in the presence of a short denticulate neck in the pore and in the bigger dimensions. T. atrata var. pustulosa Conr., T. koliana Hort., and T. gregussii Hort., all have similar dimensions and shape, but each one could represent an ornamentation type similar to those observed in our specimens. However, they differ in their conspicuous curved neck. Among the taxa ornamented with tubercles, Bourrelly (1987) described T. pseudofelix var. helicoida and T. pseudofelix var. ornata, both showing the same dimensions, shape and color, and differing only in the protuberances disposition. Their lorica are very similar to our type c specimens, however, they differ in their bigger dimension. Sanchez Castillo & De La Rosa Alamos (1993) described an important surface variability in a new taxon, T. tuberculata var. nevadensis, which was related to heavier iron mineralization of the lorica. This variety presents chloroplast without pyrenoids and a clearly different ultrastructual ornamentation pattern as compared to our specimens. At least, T. spirillifera Schkorb., was the only species that presents the same lorica dimensions, similar pore structure than our specimens and its ornametations was coincident with our type a.

    Lorica 31-34 um long, 21-23 um broad, ellipsoid, with both ends rounded. Membrane yellowish or reddish-brown, strongly and regularly punctuated (100-150/100 um2), ornamented with robust (4-6 um long) conical spines regularly (8-10/100 um2) distributed. The determination of this taxon was specially uneasy. We included it in T. zingeri, though in the figure given by Roll (Huber-Pestalozzi 1955), the sides are slightly straighter than in our specimens. In addition, though the anterior spines are not longer than posterior ones in the specimens shown, we observed this feature many times under light microscope. Finally, it differs from T. spectabilis Defl. by its larger dimensions (53-55x32-35 um). (ref. ID; 4966)
