Treatment

Protozetes capitulum BALOGH, 1962 View in CoL

( Figs 12–13 View Figs 12–13 )

Diagnosis: Rostrum wide, conical in dorsal view. Lamellae comparatively narrow, covering only the lateral prodorsal margin. A pair of weak, short, horizontal apophysis and an Y-shaped, narrow, unpaired median apophysis also present. Sensilllus clavate, distal margin with short bristles. Epimeral borders – excepting bo. 4. – thin and divided into some short parts. Along genital plates some longitudinal lines present.

Complementary redescription (holotype): Lamellae mostly with one outer apex, sometimes an other, much shorter apex also exist near to it. Transversal apophyses weak, short, ending far from each other. Longitudinal apophysis distictly Y-shaped, its lateral part long, not narrower than longitudinal ones ( Fig. 12 View Figs 12–13 ). Peduncle of sensillus short, its head elongated, fusiform with barbs on the anterior margin. Notogastral surface with a peculiar design, it consisting of thin, hardly observable laths. Notogastral setae short, blunt at tip, some of them nail-shaped, with dilated apex. Anterior transversal and longitudinal borders of the epimeral region indented, they consists from touching parts ( Fig. 13 View Figs 12–13 ). Wide, posterior border with a pair of small hollows near to setae 4b. Behind them 3 longitudinal lines running from a secondary transversal line to the comparatively large spots. Anogenital setae – excepting the anterior genital ones – minute.

Protozetes clavatus MAHUNKA et PALACIOS-VARGAS, 1996

( Figs 14–16 View Figs 14–16 )

Diagnosis: Rostrum conical dorsally, resembling a pig’s-snout laterally. Lamellae large, covering the lateral margin, originating far from each other, without true cusps, their distal part divided, bearing some strong spines. No true translamella present, a pair of well-sclerotised horizontal apophysis present. Lamellar setae arising at the median part of the inner lamellar margin. Interlamellar setae short, inserted on the lamellar surface. Sensillus clavate, with 2–3 minute acicules. Interlamellar region with long, tricuspidate longitudinal apophysis.

Material examined: Complementary redescription based on type series deposited in HNHM .

Prodorsum: Rostrum conical in dorsal, and broad, snout-like in lateral view. Lamellae very large, originating laterally far from each other. Their distal part without apices, bearing some thin, digitiform appendages. Between the lamellae a pair of curved apophyses and a weak translamella present. In the interbothridial region an odd apophyses also present basally ( Fig. 14 View Figs 14–16 ), its distal end mostly with three small teeth *. Lamellar setae arising on small tubercles at the inner margin of the lamellae, they are long and curved. Interlamellar setae short, simple, arising on the lamellar surface laterally. Sensillus capitate, directed outwards and forwards, two-three small spicules on its distal margin.

Notogaster: Dorsosejugal suture straight, without hollow. Pteromorphae small, triangular, with sharp lateral corner. Dorsal surface of notogaster with a pair of “S”-shaped lines, consisting of small pustules, like a collar of pearls. Nine pairs of short and nail-shaped notogastral setae, all nearly equal in length. Setae lm originating in the posterior part of notogaster.

Lateral part of podosoma: Tutorium long, spiniform, reaching to the rostral apex. Insertion of rostral setae covered by it ( Fig. 16 View Figs 14–16 ). Pedotecta 1 with strong, parallel lines running on the anterior margin. Pedotecta 2–3 and discidium well developed, they are ornamented with a similar pattern as pedotecta 1.

Ventral regions: The shape of apodemes and epimeral borders typical for this genus, only one complete transversal band (bo. 4) and two shorter and divided apodemes (bo. 2 and bo. sej.) present ( Fig. 15 View Figs 14–16 ). Between them exists a weak and also divided longitudinal connection. Epimeral surface 4 with an irregular polygonal pattern, rest of surface smooth. Epimeral setae short and simple, setae 1c located far from the pedotecta 1. Epimeral setal formula: 3 – 1 – 3 – 3. Along genital plates a few lines on the ventral plate, they reaching to the aggenital setae. Anterior pair of the genital setae well ciliate and much longer than the remaining ones. A pairs of roundish spots, behind the aggenital setae visible. Anogenital setal formula: 6 – 1 – 2 – 3. Lyrifissure iad long, located in adanal position.

Legs: Typical for the family.

Remarks: The species is distinguished by the following key.
