The cheliped and ambulatory legs are light brown. Sternum and abdomen are also light brown. Remarks. Chhapgarus intermedius (Chhapgar, 1955) comb. nov. was described on the basis of 14 specimens (ten males; two females and two ovigerous females) collected from Mumbai (Bombay), Maharashtra State, India (Chhapgar 1955). The holotype male, which was deposited in Zoological Survey of India, Kolkata has been examined in the present study but the rest of the specimens (paratype) examined by Chhapgar (1955) are not traceable. Fresh specimens examined in the present study show agreement with the illustrations and original descriptions given by Chhapgar (1955).Published as part of Ng, Ngan Kee, Trivedi, Jigneshkumar & Bhat, Mithila, 2022, Redescription of Pseudograpsus intermedius Chhapgar, 1955 (Decapoda, Brachyura, Varunidae) from India, pp. 127-138 in Zootaxa 5209 (1) on page 131, DOI: 10.11646/zootaxa.5209.1.7, http://zenodo.org/record/732261

The telson is triangular and mobile (Fig. 3B, E). The vulvae are large, obliquely ovate and positioned on the anterior part of sternite 6, without any sign of a sternal vulvar cover (Fig. 3C, F). Colour. The coloration of fresh specimen slightly varies from that given by Kemp (1915). The carapace is pale brown (pale French grey according to Kemp 1915) with irregular patches of purple red. The chelipeds are dark purple with fingers pale brown; the ambulatory legs are pale brown in colour, and the ventral surface of the cephalothorax is whitish. Distribution. So far, the species is only known from its type locality Chilika Lake located in Odisha state of India (Kemp 1915; Deb 1995; Mohapatra et al. 2007; Dev Roy and Nandi 2008; Sahoo et al. 2008; Mahapatro et al. 2015; Dev Roy 2017; Dev Roy and Rath 2017; Trivedi et al. 2018). Ecology. The type and fresh specimens were collected from the depth ranging from 5 to 10 feet with muddy or sandy bottom in Chilika Lake located in Odisha state of India. Remarks. Kemp (1915: 215) noted that he had a total of 16 specimens collected from various parts of Odisha state in India: Rambha to Barkul and Nalbano at Chilika Lake, and that “the type specimens are registered under no. 8944/10” (Kemp 1915: 216). No holotype was identified. In the ZSI, there are two specimens catalogued under this number, a male and a female, and as such, both are here regarded as syntypes. The whereabouts of the other 14 specimens is not known, but they should not be regarded as syntypes as they were not identified as such in the original paper. For taxonomic stability, the male syntype is here designated the lectotype of P. alcocki Kemp, 1915. The fresh specimens obtained in the present study agree well with the description and figures of Kemp (1915). They differ only slightly from the types in terms of having faint two tuberculated ridges present on the branchial region which are more prominent in types. With regards to the male pleon, Kemp (1915: 214) commented that “The first segment is acutely produced on either side and, though it appears distinct, is in reality fused to the succeeding piece.” We have examined the lectotype male and we confirm that the two somites are actually mobile and not fused, as in the fresh material.Published as part of Trivedi, Jigneshkumar N., Mitra, Santanu & Ng, Peter K.

Assessment of the Influence of Biofield Energy Treatment on the Physicochemical and Thermal Properties of Lead Using PXRD, PSA, and DSC
No full textThe lead metal is used for different purposes, i.e. contraceptive, cosmetics, ornaments, glasses, glazes, enamels, writing material, currency, construction, lead-acid battery, etc. The objective of this study was to evaluate the impact of the Trivedi Effect® on the physicochemical and thermal properties of lead using PXRD, PSA, and DSC analysis. The lead sample was divided into control and treated parts. The control sample did not receive the Biofield Energy Treatment, whereas the treated sample received the Trivedi Effect®-Consciousness Energy Healing Treatment remotely by a famous Biofield Energy Healer, Alice Branton. The PXRD peak intensities and crystallite sizes were significantly altered ranging from -60.54% to -37.5% and -17.86% to 177.74%, respectively; whereas the average crystallite size was significantly increased by 138.96% in the treated sample compared with the control sample. The particle size values were significantly increased by 59.62% (d10), 118.05% (d50), 1976.76% (d90) and 1045.85% {D(4,3)}; thus, the specific surface area was significantly decreased by 51.15% in the Biofield Treated lead sample compared with the control sample. The latent heat of fusion was significantly increased by 15.53% in the treated sample compared with the control sample. The Trivedi Effect®-Consciousness Energy Healing Treatment might have generated a new polymorphic form of lead which could have better powder flowability and more thermal stability compared with the untreated sample. Therefore, the Biofield Energy Treated lead might minimize the lead poisoning/toxicity of the people continuosly associated with the pipe, paint, food, mining, plastic, glass, chemical, and alloys manufacturing industry.

Anterolateral margin with 5 teeth, including external orbital angle; external orbital angle triangular, directed anteriorly; first anterolateral tooth triangular, outer margin twice length of inner margin; second anterolateral teeth basally fused with 3 low, rounded tubercles, forming low swollen ridge-like structure that extends beyond junction of antero- and posterolateral margins smaller than first tooth with truncate tip, last 2 teeth depressed, blunt, broad, junction of anterolateral and posterolateral margins with 2 elevated ridges merging with epibranchial region; posterolateral margins slightly curved, convergent; posterior margin almost straight. Orbit large; ocular peduncle with pubescence of varying length on dorsal surface, suborbital angle triangular. Antennules wide, rectangular, folding transversely. Basal antennal article subrectangular, submobile; flagellum slender, elongate, entering orbital hiatus.

Third maxilliped merus squarish, outer-distal angle auriculiform; ischium rectangular, with shallow oblique sulcus; exopod relatively stout, not reaching distal edge of merus, with long flagellum. Cheliped subequal; surfaces covered with long setae. Merus almost hidden beneath carapace in dorsal view. Carpus relatively large, surface covered with large and small nodules, inner angle obtuse.

Female pleon with 6 free somites and telson; telson longer than sixth somite, distal margin rounded. Remarks. Ng (1987) reviewed Lophoplax Tesch, 1918, and recognized four species: L. bicristata Tesch, 1918 (type species, Sulawesi and Moluccas); L. sculpta (Stimpson, 1858) (Japan); L. takakurai Sakai, 1935 (Japan); and L. sextuberculata Takeda & Kurata, 1984 (Japan) (see also Sakai 1935; Takeda 1977; Takeda & Kurata 1984; Takeda & Marumura 1995). Three species previously placed in it: L. teschi Serène, 1971 (South China Sea), L. sagamiensis (Sakai, 1935) (Japan), and L. granulosa (MacGilchrist, 1905) (India), were referred to Serratocoxa Ng, 1987. Serratocoxa is now a junior subjective synonym of Cryptolutea Ward, 1936 (also see Ng & Davie 1991; Davie & Humpherys 1997; Ng & Huang 2002). Takeda & Kurata (1984) also suggested transferring Pseudocryptocoeloma symmetrinudus Edmondson, 1951 (type locality Samoa) to Lophoplax as the taxon had eight prominent and symmetrically arranged areolets on the carapace; but they did not formally do so. The re-examination of the holotype specimen of Myopilumnus andamanicus Deb, 1989, showed that the species should be referred to Lophoplax, with Myopilumnus Deb, 1989, becoming a junior subjective synonym of Lophoplax Tesch, 1918. It has all the characters of the genus as discussed above. Lophoplax andamanica can be easily differentiated from L. bicristata, L. sextuberculata and L. takakurai in having relatively shorter and stouter ambulatory legs (Tesch1918; Sakai 1935; Takeda & Kurata1984; Takeda &Marumura 1995). Lophoplax andamanica most closely resembles L. sculpta in having eight symmetrically arranged areolets on the carapace but differs in the following characters: epigastric region with quadrilateral areolets (Fig. 1A) (versus oblong in L. sculpta; Fig. 2A, B; Maenosono 2019: fig. 9A, B); protogastric region with elongated crescent shape areolets (Fig. 1A) (versus ovate or only a short crescent in L. sculpta; Fig. 2A, B, Maenosono 2019: fig. 9A, B); hepatic region with centrally depressed oblong areolets on each side (versus evenly swollen oblong in L. sculpta; Fig. 2A, B; Maenosono 2019: fig. 9A, B); first three anterolateral teeth are broad with the tips blunt (versus triangular with acute tips in L. sculpta; Fig. 2A, B; Maenosono 2019: fig. 9A, B); the last two anterolateral teeth are broad and partially fused (versus broad and not fused in L. sculpta; Fig. 2A, B; Maenosono 2019: fig. 9A, B); the front is slightly deflexed (Fig. 1B) (versus strongly deflexed in L. sculpta; Fig. 2D; Maenosono 2019: fig. 9C); the epistome is slightly narrower longitudinally (versus slightly wider in L. sculpta; Fig. 2D; Maenosono 2019: fig. 9C); the outer surface of the carpus of the cheliped is covered with many large and small nodules (Fig. 1C) (versus with only four large nodules in L. sculpta; Fig. 2F); the cheliped fingers are sharply bent downwards (Fig. 1D) (versus fingers not distinctly bent in L. sculpta; Fig. 2F; Maenosono 2019: fig. 9D); and the outer surface of the P3–P5 merus, carpus and propodus are relatively more eroded (versus smoother in L. sculpta; Figs. 2H–J). Noteworthy is that L. andamaica is the first species of this genus to be recorded from the Indian Ocean; all its congeners are western Pacific in distribution. The development and arrangement of the carapace areolets varies among the known species of Lophoplax. In L. takakurai, the carapace is almost devoid of areolets, with only rounded clusters of granules present on the protogastric and epibranchial regions (Sakai 1935: pl. 7 fig. 2; Sakai 1976: pl. 191 fig. 4). In L. sextuberculata, L. sculpta L. andamanica and L. bicristata, the carapace has 4–13 areolets depending on the species. All five species, however, share hexagonal carapaces with the anterolateral teeth distinct; and the ambulatory legs are relatively long. We do not fully agree with Takeda & Kurata’s (1984) transfer of Pseudocryptocoeloma symmetrinudus to Lophoplax mainly because its carapace is transversely ovate, the anterolateral margin only has very low, broad lobes (not teeth) and the ambulatory legs are very short. We have examined the holotype male of Pseudocryptocoeloma symmetrinudus preserved in the Bishop P. Museum, Hawaii, it agrees very well with the redescription and figures in Maenosono (2019: 32, figs. 8B, 10, 13B, 14K, L). The taxonomy of Pseudocryptocoeloma is problematic because the type species, P. parvus Ward, 1936 (from Queensland, Australia) is poorly known despite being described from 28 males and 26 females. The original description is relatively brief but noteworthy is that Ward (1936) states that the posterior and median parts of the dorsal surface of the carapace are flat, smooth and glabrous; and the anterolateral margin is only obscurely dentate. The smoothness of the dorsal carapace surface and the absence of any mention of areolets suggest that P. parvus and P. symmetrinudus are not congeneric. However, resolution of the generic affinities of the two species must await re-study of the types of P. parvus.Published as part of Trivedi, Jigneshkumar, Patel, Krupal, Mitra, Santanu & Ng, Peter K.

In larger cheliped (Fig. 3 A, C), merus with distinct rounded lobe distally on anterior margin, margin of lobe denticulate, with 4 or 5 small but distinct spines; dorsal surface medially with long striae running parallel to dorso distal margin; ventral surface covered with small pits. Carpus 1.2 times as long as broad; proximal half of dorso-anterior margin with 2 blunt or acute lobes separated by shallow notch, anterior margins of lobes slightly or distinctly denticulate; dorsal surface with 3 longitudinal crests running parallel to each other, continued to dorsodistal margin, and with scattered, moderately long setae, each crest running along anterior and posterior margins and on midline. Chela moderately broad, 1.6 times as long as carpus, 1.8 times longer than broad; dorsal surface of palm with long, oblique striae and with elevated, blunt median crest reaching base of fixed finger at most; scattered, short striae present on median crest; shallow, broad groove running parallel to posterior marginal crest, with short setae; anterior margin thin, minutely crenulate; posterior margin nearly smooth; ventral surface covered with small pits. Small or large hiatus present between fixed finger and dactylus. Fixed finger nearly equal in length to dactylus, with no distinct teeth on cutting edge; dorsal surface with short striae; posterior margin thin, minutely serrated. Dactylus nearly equal in length to palm measured on posterior margin, moderately curved distally, terminating in blunt claw; dorsal surface with short to moderately long striae; cutting edge smooth, with no distinct teeth; ventral surface with small pits in proximal half.</p> <p>Smaller cheliped (Fig. 3 B, D) with scattered striae bearing short setae on dorsal surface. Carpus with 3 longitudinal crests on dorsal surface, weaker than those of larger cheliped. Palm with shallow groove lined with short setae, narrower than that of large cheliped and running parallel to posterior marginal crest. Dactylus and fixed finger without distinct teeth on each cutting edge; ventral surface of cutting edge of dactylus with or without tuft of dense setae.</p> <p>Ambulatory legs (second to fourth pereopods; Fig. 2 A–C) stout, subcylindrical, with scattered setae on margins, setae longer on dorsal margins of carpus and propodus; lateral surfaces with scattered, short striae bearing minute setae. Meri somewhat compressed, elongate subrectangular, decreasing in size posteriorly; dorsal margin slightly crenulate, dorsodistal angle with tuft of long setae on fourth pereopod but naked or with few short setae on second and third pereopods; ventral margin nearly smooth, more convex on second and third pereopods than fourth. Carpi moderately long; dorsal margin with short striae giving undulating appearance, unarmed; ventral margin nearly smooth. Propodi 1.2 times as long as dactyli; dorsal margin slightly crenulate; laterodistal margin subacute or rounded; ventral margin with 3 or 4 (3 on fourth pereopod in holotype) corneous spines, spines increasing in size distally; distoventral margin mesially with additional spine. Dactyli each terminating in curved, sharp claw; dorsal margin smooth; lateral surface with few, moderately long setae near tip of claw; ventral margin with 4 corneous spines increasing in size distally.</p> <p> <b>Variation.</b> The morphology of the larger cheliped varies between the largest male (CL 4.08 mm, CW 3.71 mm) and the smallest female (CL 2.43 mm, CW 2.20 mm) examined. The carpus and palm have more prominent, dorsal grooves in the largest male than in the smallest female. The lobes on the dorso-anterior margin of the carpus are marginally rounded and minutely denticulate in the largest male, instead of acute and prominently denticulate in the smallest female. In males with CL larger than 3.5 mm, one chela is distinctly larger than another, but in females larger than 2.4 mm, both chelae are subequal in size. The morphology of the smaller cheliped also varies between male and female. The hiatus of the fingers of the smaller chela is covered with thick tuft of setae in males, while such tuft was not observed in smaller chela of females.</p> <p> <b>Coloration in life</b> (Fig. 4). Carapace generally light to dark brown; frontal region light cream; mesogastric, protogastric, hepatic, and epibranchial regions with dark brown patches; cardiac region dark orange; cream rounded spot with tuft of cream colored short setae present on either side of epibranchial regions. Antennal peduncle and flagellum cream, with dark brown bands. Third maxilliped cream. Chelipeds light brown, with dark brown spots and patches on dorsal surface; large cream band on articulation between chela and carpus; fingers dark brown, with tips and cutting edges cream; ventral surface of cheliped entirely cream. Ambulatory legs cream, with dark brown bands on median parts of meri, carpi, and propodi; dactyli white in each distal half, with dark brown claw. Abdomen light cream, with scattered dark brown spots.</p> <p> <b>Habitat.</b> Coral reef, under rocks; low intertidal.</p> <p> <b>Distribution.</b> Presently known only from the type locality, Shivrajpur located on the coastal region of the Dev Bhumi Dwarka District (part of Saurashtra), Gujarat, India.</p> <p> <b>Etymology.</b> The new species is named in honor of Dr. Peter K. L. Ng of the Lee Kong Chian Natural History Museum, National University of Singapore, for his great contribution in taxonomy and biology of various crustaceans including new taxa described from India.</p> <p> <b>Remarks.</b> The present new species is assigned to the genus <i>Ancylocheles</i> based on the following characters: carapace being approximately as long as broad, with regions defined but not strongly areolate; rostrum broadly triangular in dorsal view; antennal peduncle with movable (second to fourth) articles excluded from orbit by projection of immovable (first) article pressed to anterior margin of carapace; and chelipeds being generally unequal in size and not showing pronounced sexual dimorphism in armature as well as in degree of distortion of fingers (Haig 1978; Osawa 2007). Although Haig (1978) mentioned an eastern Atlantic species <i>Porcellana foresti</i> Chace, 1956 appears to be related to <i>A. gravelei,</i> the former species is clearly different from the latter by the trilobate rostrum and chelipeds without any distinct sculptures on the dorsal surface (Chace 1956; also see a note by Osawa & McLaughlin 2010: 118).</p> <p> Although we could not unfortunately examine the holotype of <i>A. gravelei</i> which is deposited in the collection of the Zoological Survey of Indian Museum, Kolkata, the present new species is distinguishable from <i>A. gravelei</i> by several characters. The carapace front is more strongly produced in dorsal view and the supraorbital margin is much more strongly concave in the new species than in <i>A. gravelei</i>. The median lobe of the third thoracic sternite is strongly convex on the anterior margin in <i>A. peterngi</i> <b>n. sp.</b>, whereas it has a rather transverse anterior margin in <i>A. gravelei</i>. The second article of the antennal peduncle is unarmed on the anterior margin in the new species, instead of having a small but distinct spine at the antero distal angle in <i>A. gravelei</i>. The ventral lobe of the merus of the third maxilliped is subrectangular in <i>A. peterngi</i> <b>n. sp.</b>, rather than rounded in <i>A. gravelei</i> (for morphology of <i>A. gravelei</i>, see Sankolli 1963; Haig 1965; Tirmizi <i>et al.</i> 1989; Hiller <i>et al.</i> 2010).</p>Published as part of <i>Trivedi, Jigneshkumar N., Osawa, Masayuki & Vachhrajani, Kauresh D., 2017, A new species of the genus Ancylocheles Haig, 1978 (Crustacea: Decapoda: Anomura: Porcellanidae) from Gujarat, northwestern India, pp. 384-390 in Zootaxa 4299 (3)</i> on pages 385-389, DOI: 10.11646/zootaxa.4299.3.4, <a href="http://zenodo.org/record/836032">http://zenodo.org/record/836032</a>
