Diagnosis. Rostrum extending beyond scaphocerite, distal part slightly curved upwards, rostral formula: 3–4 + 9–13/3–5, rl. about as long as cl. Cephalothorax, abdomen and telson smooth, without microspinules. Second pereiopods equal in both sexes, carpus and outer margin of palm covered with microspinules; fingers of male about as long as palm, fingers of female shorter (about 0.83–0.92) than palm, movable finger with 2 small denticles, fixed finger with a single denticle; carpus longer than palm, about 1.3–1.5 times as long as palm, palm distinctly swollen, 3.5–3.6 times as long as width; carpus about 1.4–1.5 times as long as merus; merus about 0.91 times as long as ischium. Egg size: 0.54–0.70 X 0.84–0.92 mm in diameter. Live coloration. Body translucent, light green. Rostrum transparent to almost colorless. Cephalothorax with blue-black diagonal strips, abdomen with blue-black transverse strips. Second pereiopods with transversal yellow bands on merus and carpus. All joints of third to fifth pereiopods with transverse yellow bands. Eggs e yellow (Fig. 7D). Remarks. The present material can be confidently assigned to M. inflatum due to the very inflated palm, the ratio of the segments of the male second pereiopods, the upturned rostrum and the rostral formula. Cai & Dai (1999) pointed out that M. inflatum was reported from Yunnan Province may be caused by human introduction. In recent years, we have however collected and examined numerous specimens of this species in various freshwater bodies from Hunan and Guangdong Province. It is usually found together with M. nipponense. Therefore this species may be naturally distributed in southeastern China. This is the first record of the species from Guangdong Province. Distribution and habitat. Southeastern China (Jiangsu, Anhui, Hunan, Guangdong and Yunnan Provinces). This species is found in various freshwater bodies, such as ponds, rivers, lakes and reservoirs. It seeks shelter among aquatic vegetation.Published as part of Guo, Zhao-Liang & He, Shun-Lian, 2008, One new and four newly recorded species of the genus Macrobrachium (Decapoda: Caridea: Palaemoindae) from Guangdong Province, southern China, pp. 11-25 in Zootaxa 1961 (1) on page 21, DOI: 10.11646/zootaxa.1961.1.2, http://zenodo.org/record/524155

Diagnosis. Rostrum reaching as far as or extending beyond end of antennular peduncle, upper margin slightly convex above eyes; rostral formula: 4–7 + 6–8/2–4, rl. about 0.40–0.50 cl. Cephalothorax, abdomen and telson smooth, without microspinules. Second pereiopods subequal in both sexes, all segments rough, covered with appressed scales, those on inner margin spiniform, finger about 0.44–0.71 times as long as palm, cutting edges of fixed finger with 2–4 teeth, basal tooth formed of 4–12 (usually 4 or 5) denticles, movable finger with 3–6 tooth in proximal half to two–thirds; carpus shorter than palm, about 0.62–0.91 times as long as palm, palm slightly compressed, subcylindrical, 3.3–4.9 times as long as width; carpus cylindrical, about 1.1–1.3 times as long as merus; merus about 1.1–1.6 times as long as ischium. Egg size: 0.42–0.47 X 0.51– 0.65 mm in diameter. Live coloration. This prawn seems to be quite variable in color, with at least three color variations. In specimens collected from rocky beds, under pebbles and stones, the body and appendages are buff with irregular dark brown or red spots (Fig. 4). In specimens collected from sandy substrates, the body is very dark brown, the cephalothorax has yellow spots, and the abdomen and telson have irregular yellow stripes and spots. Those from localities with a much aquatic vegetation have a bluish-green body with irregular dark brown spots. The eggs are grass green. Remarks. The first record of Macrobrachium meridionalis Liang & Yan, 1983 was from Chengmai County, Hainan Island, southern China. The description was based on three small specimens (Liang & Yan, 1983). Recently, Yeo et al. (1999), after reexamining the paratype and observing the specimens from Peninsular Malaysia, provided additional details of the morphology of M. meridionalis and expanded its distribution in Peninsular Malaysia. The present specimens essentially match the definition of the present species as given by Liang & Yan (1983), Liu et al. (1990) and Yeo et al. (1999). There are some minor differences compared to the type specimens. The rostral formula of the Guangdong specimens is 4–7 + 6–8/2–4 versus 5–6 + 7–8/ 2–3 in the types. The tooth arrangement of the cutting edges of the fingers of the major male second pereiopod is quite variable; the fixed finger has 2–4 teeth, the basal tooth is formed of 4–12 (usually 4 or 5) denticles, movable finger with 3–6 tooth in proximal half to two-thirds (Fig. 5). There is a distinct longitudinal groove along the each surface of the palm of second pereiopods of the fully developed adult male (Fig. 6). Yeo et al. (1999: 227) also found a very distinct sulcus along the length of the carpus and the proximal half of the palm, and noted other differences such as a relative longer and slender finger of the second pereiopods. This is the first record in the Guangdong Province. When living animals are attacked, the second pereiopods are easily broken off the body. Therefore, most living specimens sold in markets and most preserved specimens have lost their second pereiopods. This species is commercially important in Guangdong Province. It is fished for home and restaurant consumption as a special dish and sometimes it is sold in large quantities in fish markets. In markets, the price of this species is double that of other freshwater prawns such as M. nipponense, because of their size and the excellent flavour. Local commercial fishermen call it Shi xia (meaning stone prawn) due to its habitat, i. e., usually in crevices among stones. Distribution and habitat. Southeastern China (Guangdong and Hainan Provinces) and Malaysia (Pulau Tioman). The species seems to be restricted to relatively slow flowing rivers above the reach of tidal influence.Published as part of Guo, Zhao-Liang & He, Shun-Lian, 2008, One new and four newly recorded species of the genus Macrobrachium (Decapoda: Caridea: Palaemoindae) from Guangdong Province, southern China, pp. 11-25 in Zootaxa 1961 (1) on pages 18-21, DOI: 10.11646/zootaxa.1961.1.2, http://zenodo.org/record/524155

W. + M. Klotz 0 3.04. 2009. In 2009 several specimens of bee shrimp could be collected from two hill streams near the Xingfengjiang Reservoir, Heyuan County, Guangdong Province. According to a local fisherman collecting shrimp for the aquarium trade in this area, the same species can be found in about 20 streams near the Xingfengjiang Reservoir. Specimens from both streams sampled agree well with the original description in both morphology and life coloration of Caridina meridionalis Wang, Liang & Li, 2008 (see colour plate 2 C for comparison with fig. 8, page 58 in Wang et al. 2008). Wang et al. (2008) did not mention the branchial formula of their specimens. In the specimens examined the first pereiopods are lacking an arthropod and this species should thus be assigned to Paracaridina. Amongst the known members of Paracaridina, C. meridionalis (based on the bee shrimp herein examined) is very similar to P. z i j i n i c a Liang, 2002, also described from Heyuan County, differing only in the length of the stylocerite, which reaches almost to the end of the first antennular peduncle in P. meridionalis vs. reaching to the end or slightly overreaching this segment in P. zijinica). As this difference is considered to be intraspecific variation, C. meridionalis Wang et al. 2008 is here considered to be a junior synonym of P. z i j i n i c a.Published as part of Klotz, Werner & Rintelen, Thomas Von, 2014, To " bee " or not to be — on some ornamental shrimp from Guangdong Province, Southern China and Hong Kong SAR, with descriptions of three new species, pp. 151-184 in Zootaxa 3889 (2) on pages 180-181, DOI: 10.11646/zootaxa.3889.2.1, http://zenodo.org/record/25272
