B86A87A9FFF0FF6BFCC5CC2F484EFA28.taxon	description	(Fig. 7 A) The sample comprises two females (22.7 mm SL and 33.9 mm SL). The specimens have no modified pectoral fins. This modification, the lamina circularis, is a hardening of the innermost pectoral fin rays, is found only in males (Havird and Page, 2010) and is already present in juveniles (personal observation). Coloration and body shape separate L. thermalis unambiguously from L. jonklaasi, the second species of the genus in Sri Lanka. Additionally, both species are spatially separated. Lepidocephalichthys thermalis is widely distributed in the entire lowlands of Sri Lanka, whereas L. jonklaasi is confined to small streams of the rainforests of the south- western wet zone (Sudasinghe et al., 2024). As these authors stated, L. thermalis is a species complex and needs taxonomic revision. Hacker’s sample could be the basis in the redescription of the “ true ” L. thermalis. These two specimens are the second and unambiguous record of L. thermalis from the hot springs of Kanniya.	en	Ahnelt, Harald, Sudasinghe, Hiranya (2024): A collection of fishes from the enigmatic type locality of fish species described by Georges Cuvier and by Achille Valenciennes, the hot springs of Kanniya at Trincomalee, Sri Lanka.

B86A87A9FFF0FF6CFCC5C95D4904FC61.taxon	description	The sample comprises five specimens. With a size of 26.6 mm SL to 35.3 mm SL, all these specimens are juveniles. The closest recent records of a Rasbora species to the hot springs are R. microcephalus (Silva et al., 2010) and R. cf. adisi and R. dandia (Sudasinghe et al., 2020) and were documented from tributaries of the Mahaweli Ganga with the localities approximately 35 km (R. microcephalus) and 50 km (R. cf. adisi and R. dandia) distant to Kanniya. These three species are the only species of Rasbora, which occur in the lowlands of the northern dry zone of Sri Lanka (Sudasinghe et al., 2020). The coloration, the absence / presence of a ventral projection at the jaw articulation, the absence / presence of a lachrymal groove and the prominence of the symphysal knob are the main morphological traits to separate adults of these three species (Sudasinghe et al., 2020). With 35.3 mm SL, the largest specimen from Hacker’s sample is not fully grown. It is distinctly smaller than adult specimens of the three species potentially occurring in the area (R. cf. adisi 50.8 - 73.8 mm SL, R. dandia 45.0 - 89.6 mm SL, R. microcephalus 47.8.8 - 99.9 mm SL) (Sudasinghe et al., 2020). The absence of a lachrymal groove, the presence of a slight ventral projection at the jaw articulation, and the colour pattern (Fig. 7 B) indicate that both specimens are R. microcephalus. Unfortunately, genetic analysis of the five specimens is not possible because Hacker preserved all the samples in formalin. Duncker (1912) mentioned Rasbora daniconius from close to the hot springs of Kanniya. But R. daniconius is confined to India (Silva et al., 2010; Sudasinghe et al., 2020). Duncker brought two specimens to the Museum der Natur Hamburg (ZMH – ICH) (Fig. 8). With a SL of 39.3 mm and 40.1 mm these specimens are somewhat larger than those from the hot springs collected by Hacker. Also, these two specimens have no lachrymal groove but an indistinct projection of the jaw articulation (Fig. 8) and are in fact R. microcephalus. The five specimens collected in the most downstream spring (well 7) (Fig. 3 B) in 1982 by R. Hacker are the first record of this species from the hot springs of Kanniya.	en	Ahnelt, Harald, Sudasinghe, Hiranya (2024): A collection of fishes from the enigmatic type locality of fish species described by Georges Cuvier and by Achille Valenciennes, the hot springs of Kanniya at Trincomalee, Sri Lanka.
