consists of' slightly coiled tube and grooved accessory piece bearing protruding sclerite. Vagina dextral with sclerotised funnel-like opening and short vaginal tube. Male and female reproductive structures as in T. trichogasterium sp. n. Remarks The general shape of the anchors in this species and T. trichogasterium sp. n. are basically similar except that in this species the 3 anchors are almost of similar size, while in T. tri chogasterium sp. n. the ventral anchors are slightly shorter. This species is named Trianchoratus leerium sp.n. after the name of its host. Trianchoratus gussevi sp.n. (Fig. 27-33). Host: Anabas te_stu_dine_u^ (Bloch) (Anabantidae). Locality: Tanjung Karang, Selangor (type locality), Bukit Merah Reservoir, Perak. Type specimens: Holotype USNM No. 78038; Paratype USNM No. 77281 and UMZD(P) No. 23. No. measured: 15. Body size 338 (316-417) x 86 (52- 125). Alimentary system as in T. trichogasterium sp.n. Dorsal anchors unequal, right anchor rudimentary, somewhat arcuate, length 12 (11-13); left anchor developed, inner length 30 (28-30), outer length 30 (28-32), inner root 17 (14-18), outer root 8 (6-10) and recurved point 20 (20-24). Ventral anchors equally developed, inner length 31 (29-34), outer length 31 (28-32), inner root 15 (14-18), outer root 7 (6-8) and recurved point 28 (25-30). All developed anchors oriented ventrally. Haptoral bar absent. 14 marginal hooks, proximal tip with knob resembling a pin-head, length 13 (10-14). Copulatory organ consists of slightly coiled tube and grooved accessory piece bearing protruding sclerite. Vagina dextral with sclerotised funnel-like opening and short vaginal tube. Male and female reproductive systems as in T. trichogasterium sp.n. (Fig. 20). Remarks This species possesses anchors in which the terminal quarter or point is more bent compared to anchors of T. acleithrium, T. trichogasterium sp. n. and T. leerium sp. n. This species is named Trianchoratus gussevi sp.n. in honour of Dr. A.V. GUSSEV of the Zoological Institute, USSR Academy of Sciences, Leningrad who has illustrated the same species from A. testudineus in India in 1978 without naming it. Trianchoratus grandis sp.n. (Fig. 34-38). Host': Anabas testudineus (Bloch) (Anabantidae). Locality: Tanjung Karang, Selangor (type locality) and Bukit Merah Reservoir. Type specimens: Holotype USNM No. 77283; paratype UMZD(P) No. 24. No. measured: 5. Body size 414 (427-521) x 98 (83- 115). Alimentary system as in T. trichogasterium sp.n. Dorsal anchors unequal, right anchor rudimentary, somewhat arcuate, length 17 (15-18); left anchor developed, inner length 56 (54-57), outer length 48 (45-50), inner root 31 (30-32), outer root 4 (3-5) and recurved point 33 (30-35). Ventral anchors equally developed, inner length 37 (36-39), outer length 38 (36-40), inner root 24 (23-26), outer root 7 (6-8) and recurved point 23 (20-25). All developed anchors directed ventrally. Haptoral bar absent. 14 marginal hooks, proximal tip with knob resembling a pin-head, length 13 (10-14). Copulatory organ consisting of slightly coiled tube and grooved accessory piece bearing protruding sclerite. Vagina dextral with sclerotised funnel-like opening and short vaginal tube. Remarks This species differs from other Trianchoratus species in having a very large left dorsal anchor. The shape of the ventral anchors in this species is also different from those in the other Trianchoratus species. This species is named Trianchoratus grandis sp.n. because of the large dorsal anchor.
