Description

CEPHALOTHORAX. Antennal spine ventral to inferior orbital angle. Pterygostomian margin rounded. Rostrum ( Fig. 23 View Fig m–n): straight, short, 0.6–0.9 of cl, reaching beyond end of antennular peduncle, armed with 22–26 teeth on dorsal margin, 7–10 of them situated on carapace behind orbital margin, ventral margin with 6–7 teeth. Eyes developed, anterior end reaching to 0.54 times length of basal segment of antennular peduncle. Long antennular peduncle, 0.78 (♀) – 0.95 (♂) times as long as carapace; second segment distinctly longer than third segment. Stylocerite reaching to middle of second segment of antennular peduncle.

PEREIOPODS. Epipods on first four pereiopods. P1 ( Fig. 23a View Fig ): chela about 2.3–2.9 times as long as wide, movable finger 4.1–5.1 times as long as wide, 1.1–1.8 times length of palm; carpus 3.3–4.5 times as long as wide. P2 ( Fig. 23b View Fig ) more slender and longer than first pereiopod, with chela 3.7–5.1 times as long as wide: movable finger 6.0–8.3 times as long as wide, 1.7–1.9 times length of palm; carpus slender, 8.3–10.9 times as long as wide. P3 ( Fig. 23c View Fig ): slender, dactylus ( Fig. 23e View Fig ) 3.7–4.4 times as long as wide (terminal spiniform seta included), with 6–7 spiniform setae on flexor margin including terminal one; propodus 14.2–17.1 times as long as wide, 4.1–5.3 times as long as dactylus, distinctive very long seta on distal end of carpus and merus. P5 ( Fig. 23d View Fig ): dactylus ( Fig. 23f View Fig ) 4.5–5.5 as long as wide, with 10–15 spiniform setae on flexor margin; propodus 18.7–24.0 times as long as wide, 4.5–5.5 times as long as dactylus.

ABDOMEN. Third abdominal somite with moderately convex dorsal profile. Sixth abdominal somite 0.56 times as long as carapace, 1.7 times as long as fifth somite, shorter than telson.

TELSON ( Fig. 23i View Fig ). 2.5–3.5 times as long as wide, with five pairs of dorsal spinules and pair of dorsolateral spinules; posterior margin with small median process, rounded, with 8–10 very long intermediate plumose setae longer than lateral ones.

MALE PLEOPODS. Pl1 ( Fig. 23j View Fig ): endopod rounded, 1.4 times as long as wide, reaching 0.22 times length of endopod, no appendix. Pl2 ( Fig. 23k View Fig ): appendix masculina reaching 0.77 times length of endopod; appendix interna reaching 0.75 times length of appendix masculina.

PRE- ANAL CARINA ( Fig. 23g View Fig ). High, with a spine.

UROPODAL DIAERESIS ( Fig. 23h View Fig ). With 15–17 spinules.

EGGS. Ovigerous females with small eggs, size: 0.30–0.38 × 0.18–0.23mm.

Habitat

Caridina serratirostris   lives from the estuarine brackish water to the fresh water in the lower course of the rivers.

Colour pattern ( Fig. 26D View Fig )

The body is yellowish to reddish with many red dots.

Distribution

This species occurs in Indonesia (Selajar), the Solomon Islands, Australia and Papua New Guinea (New Britain).

Remarks

Our specimens fit well with the types from Selayar: straight rostrum, 0.6–0.9 of cl (vs 0.6–0.9 in the type specimens), sometimes reaching the end of the antennular peduncle, armed with 22–26 teeth on dorsal margin (vs 20–27), 7–10 of them situated on carapace behind orbital margin (vs 8–9), ventral margin with 6–7 teeth (vs 4–7); P1 carpus 3.3–4.5 times as long as wide (vs 3.1–4.9); P2 carpus 8.3–10.9 times as long as wide (vs 7.0–9.0); P3 dactylus with 6–7 spiniform setae (vs 6–7) propodus 4.1–5.3 times as long as dactylus (vs 3.8–4.2); uropodal diaresis with 15–17 spinules (vs 14–19); small eggs, 0.30–0.38 × 0.18–0.23 mm (vs 0.28–0.31 × 0.13–0.15); no appendix interna on the endopod of the male first pleopod.
