Soós, Á.: On the genus Batracobdella Viguier, 1879, with a key and catalogue to the species (Hirudinoidea: Glossiphoniidae)

Batracobdella VIGUIER, 1879 Batracobdella VIGÜIER (1879): C. R. Acad. Sei. Paris, 89, p. 110-112. Synonymy: Batrachobdella VIGUIER (1879) (nee CABALLERO, 1931): Ann. Mag. Nat. Hist., (5) 4, p. 250-251. Clepsinides AUGENER (1926): Zool. Anz., 68, p. 244 — 246. Dundjibdella SCIACCHITANO (1939): Rev. Zool. Bot. Afr., 32, p. 353. Diagnosis : Glossiphonid, generally of small size. Body elongate, ovate, ovato-elliptical or sublanceolate, dorso-laterally depressed, dorsally slightly convex and ventrally nearly flat or concave. Head and sucker either not separated from body or more or less widened, respectively definitely expanded. Caudal sucker circular or discoidal, distinct from body, attached centrally, directed ventrad, sometimes with a well-formed peduncle invariably narrower than maximum body width (except magnidiscus MOORE). Body opaque, transparent, gelatinous or soft. Colour and pattern most varying but generally unicoloured. Surface either smooth or with varying rows of sensory papillae. Complete somite triannulate (a

). Number of complete somites almost invariably 20 (V—XXIV). Total number of annuli between 67—72 (?74). Eyes typically one or two pairs, rarely three; in certain cases coalescence possible in various combinations. Mouth a minute pore in middle or near centre of cephalic sucker, mostly on a small, isolated papilla. Salivary glands diffuse, rarely compact. Oesophageal organ present in anatomically known species. Crop with seven (XIII— XIX) lateral diverticula (agastric caeca); last elongated pair directed posteriorad; intestine with four pairs of intestinal sacs. 0—2 postanal annuli. Six pairs of testes intersegmental (XIII/XIV—XVIII/XIX). Genital pores separated by 2, rarely by 1 or V-j

2 annuli. Atrium small, atrial cornua fusiform, bulbus ejaculatorius absent, epididymis winding or forming a loose coil. Vagina short, ovisac a simple, elongate tube, terminally exceptionally recurving. Type-species : Glossiphonia algira MOQUIN-TANDON, 1846. Key to the Species oi the Genus Batracobdella Viguier, 1879 1 (12) Male and female gonopores separated by one or one and a half annuli (Figs. 1 — 3). Head not separated from body by a narrow, necklike constriction (Figs. 7—10, 12), except in quadrata MOORE (Fig. 11). 2 (5) Male and female gonopores separated by one and a half annuli, Ö* = XI/XLT, 9 =XIIa

2 (Fig. 1). Of three last somites, XXV biannulate, XXVI and XXVII uniannulate (Figs. 13—14). 3 (4) Three pairs of eyes present (Fig. 7). One postanal annulus (Fig. 13). Total number of annuli 70. "The receptors are present in large numbers all over the dorsal surface of the body, and for this reason the dorsal surface appears areolated. The receptors are thickly set and form irregular rows on each annulus. Some of the receptors appear circular, others transversally oval" (BAUGH, p. 296). Caudal sucker less than half of maximum width of body (Fig. 13). A pair of compact salivary glands. Preserved specimens colourless. Length: 3 mm; width: 1.5 mm. Host: unknown. — India hardingi BAUGH, 1960 4 (3) Two pairs of eyes present (Fig. 9). No postanal annulus (Fig. 14). Total number of annuli 69. Dorsal surface entirely s nooth. Caudal sucker circular, its diameter slightly greater than half of maximum width of body. Uniformly brown, but median stripe and two lateral stripes colourless. Length: 12 mm; width: 3.5 mm. Host: frogs. — China singularis (OKA, 1931) 5 (2) Male and female gonopores separated by one annulus (Figs. 2 — 3); rf = XI/XII>
