A New Species

AbstractIn this study a new species of nematode, Iheringascaris goai n. sp., is reported from two fish hosts, including silver whiting, Sillago sihama, and spotted catfish, Arius maculatus, caught off the Central West Coast of India at Goa. The new species can be differentiated morphologically from I. inquies, the most closely related species collected from cohabiting marine fish. The distinguishing characteristics are distinct cuticular striations, a unilateral excretory system, the presence of dentigerous ridges on the inner margin of the lips and the ratio of oesophagus to body length. In males, the ratio of spicules to body length is higher and the number of pre-anal papillae is less in comparison to those in I. inquies. In addition, the tail curves ventrad in males, while in females, the vulva is post-equatorial. The sequence alignment of 18S rDNA and cytochrome c oxidase subunit I with sequences of known species selected from the same superfamily shows a significant difference. The morphological and molecular differences reported here can, therefore, be used to assign the specimen to a new species.

A New Species

Abstract This study dealt with three species of ornamental palaemonid freshwater prawns of the genus Macrobrachium, based on morphological and molecular analysis. Macrobrachium pentazona He, Gao & Guo, 2009; M. laevis Zheng, Chen & Guo, 2019; and M. bilineare sp. nov. are distinguishable from closely related species by segmental ratios, spination of the second pereiopods and the slender scaphocerite. Macrobrachium bilineare sp. nov. can easily be recognized in the field by its bright colour pattern. Molecular evidence of mitochondrial cytochrome oxidase subunit I (COI), also supports the characterization of this new species, raising the total number of Macrobrachium spp. known from China to 41. Detailed description, illustrations, colour photographs, habitat information, distribution maps and features of conservation significance are also briefly discussed.

A new species of copepod, Paracalanus arabiensis sp. nov. collected from Mandovi and Zuari estuaries, Goa, central west coast of India, is described. It differs from its congeners mainly in the structure of leg 5, with a row of six teeth along the edge of inner terminal spine resulting in a serrated margin and two small, stiff spines of equal length protrude in between the terminal spines.

Euphorbia kadapensis, a new species of Euphorbiaceae is described from Kadapa district in Rayalaseema region of Andhra Pradesh, southern India. It belongs to Euphorbia subgen. Chamaesyce. Within the group, it resembles E. concanensis, E. longistyla and E. senguptae of sect. Anisophyllum subsect. Hypericifoliae though the affinities are more so with the allopatric E. concanensis from the west coast of India.

A New Species

A new species of microhylid frog Microhyla kodial sp. nov. from the west coast of India is described in this paper. It is distinct from all described species of Microhyla occurring in South and Southeast Asia as revealed by a combination of morphological, molecular and acoustic characters. The new species is characterized by absence of lateral body stripe, tuberculated dorsal skin surface, absence of webbing between fingers, presence of basal webbing between toes and absence of dorsal marginal groove on finger and toe disc. Each male advertisement call lasts for 0.11–0.42 s and is comprised of 2–7 pulses with a dominant frequency of 3.3–4.2 kHz. The breeding season is short, limited to the rainy season (June to September) and the females lay up to 300 eggs per clutch. A molecular phylogenetic tree constructed using the mitochondrial 16S rRNA gene shows that M. kodial sp. nov. is closely related to the M. achatina group from Southeast Asia. The uncorrected genetic divergence between the new species and its closest congeners M. heymonsi, M. mantheyi, M. borneensis and M. orientalis were 7.3–7.6 %, 7.5–7.8%, 7.8–8.1% and 8.1–8.4% respectively. At present, this species is known only from the type locality, a highly disturbed urban and industrialized area which needs conservation intervention.

Deep Body

A new species, Amblygaster indiana sp. nov., is described from 12 specimens collected from fish landing centers and fish markets at Eraviputhenthurai, west coast of India. The new species can be differentiated from all other species of Amblygaster by its larger size and very deep body, 8 circular-shaped pre-pelvic scutes, different gill rakers counts, large eyes, 40 lateral scales, and peculiar gap between the left and right frontoparietal striae on the top of the head. The new species has been seasonally captured with A. sirm in Eraviputhenthurai and also other coastal waters of the south west coast of India. The proportions of A. indiana sp. nov. and A. sirm in fish catches are approximately 1 to 20. Gillnets and shore seines are used to catch Amblygaster spp. along the Eraviputhenthurai coast and along the coastal zones of south west coasts of India.
