Review of Monograph
West Bengal
spiders (Araneae: Arachnida)
Opis:
The monograph on mulch and soil spiders (Araneae: Arachnida) which are to be found in the reserves of West Bengal (Jalpaiguri District) submitted for review has 222 pages of text, 2 tables, 494 black and white and 9 colour figures, and 26 colour plates. The whole treatise is supplemented with a list of references which includes 119 items, including the most important ones, such as World Spider Catalogue (2016). The final section contains an alphabetic list of Latin names being used throughout the said monograph. Within the area studied, 89 spider species have been reported that belong to 38 genera and represent 13 families. Apart from endemic species (38 species), the species brought into from other zoogeographic regions, such as Australian, Ethiopian, Nearctic or Neotropical Regions, have been reported. It is a pity that the authors did not attempt to explain the migration routes by which these foreign spiders for the area under study reached it. The treatise contains description of a newly discovered spider species that belongs to the genus Hamataliwa Keyser. Unfortunately, the authors did not fully explain the importance of this new species but only referred to a similar, previously known name. A difference in Latin names, i.e. in one or two “l”, is correct in zoological nomenclature but undoubtedly will create a lot of mistakes, especially as the two names belong to the same genus. Really beautiful and very accurate figures that characterise individual species are extremely valuable for the treatise being discussed. Also colour plates that show individual species as they occur in nature, that is before being placed in a preserving substance, are very useful. The monograph being presented greatly increases our knowledge on mulch and soil spiders of the studied reserves, and the same of the fauna of India, which is still considered one of the least recognised in terms of invertebrates.

Opis:
Our study on ant diversity of Bibhutibhusan Wildlife Sanctuary, N-24 Parganas, West Bengal during the period, August 2017-July 2018, unfolded wonderful Batesian and Wasmannian mimicry (chemical mimicry) between model ants Tetraponera rufonigra (Jerdon) and its sibling T. allaborans (Walker), Oceophylla smaragdina (Fabricius) and salticid spiders of the genus Myrmarachne Macleay. Siblings of Myrmarachne encountered are M. plataleoides O. P. Cambridge, M. maratha Tikader and M. orientales Tikader. It is supposed that chemical or Wasmannian mimicry enables species with ant-like pheromones to live in close contact with ants. The members of spider Myrmarachne that resemble the aggresive weaver ant Oceophylla smaragdina, with which they live in close contact, also show chemical resemblance. Further, by mimicking the ants they gain protection from predators. Since weaver ants have a painful bite and also taste bad, this strategy appears to be successful. Though these spiders mimic the weaver ants very well, they are known to stay away from them. They weave a thin web on the leaves, hide under their webbing and ambush their prey. Present communication attempts to discuss the morphological and structural similarities between the mimics and their models. It is worthwhile to mention that such a mimicry is reported for the first time from this part of the country.

Opis:
The present study is on the spider fauna of Barasat and Basirhat of North 24 Parganas, West Bengal, India. A total of 23 species belonging to 20 genera and 11 families are sampled during the period August 2016 to July 2017. These include the newly recorded species, Anepsion maritatum (O.P. Cambridge) from the state. The dominant guild is constituted by the Orb web weavers (30.43%). Analysis of their zoogeographical distribution reveals that the fauna apart from being Oriental also includes some Australian (23%), Palaearctic (21.73%) and Ethiopian, Nearctic and Neotropical (each 17.39%) elements. Spiders are mostly prevalent during Postmonsoon (82.60%), followed by Premonsoon (60.86%) and Monsoon (47.82%) which is in conformity with the incidence of the insect species. Two species namely Eriovixia excelsa (Simon) and Leucauge decorata (Blackwall) are recorded throughout the period of survey. All the diversity indices are higher in case of Basirhat as compared to Barasat. An overall negative impact of urbanization on spider diversity, distribution and abundance is evidenced from the present study. Ranking sequence of the most abundant species (six) in descending order are: Leucauge decorata (25.68%) > Eriovixia excelsa (19.13%) > Pholcus phalangioides (11.48%) > Plexippus paykullii (8.74%) > Anepsion maritatum (7.10%) > Cyrtophora cicatrosa (6.56%). Sex ratio (♀ : ♂) is about 12 : 1. Availability of food/season and/or cannibalism may be the factors for female dominated society.

Opis:
Spiders have established themselves as a model group in biochemical (silk and venom proteins), behavioural (sexual and web building behaviours) and ecological (foraging, prey-predator interaction and IPM) research. They are also utilized as ecological indicators in many terrestrial communities. Appreciating the bioresource value of spiders, present discourse is second in the series on the spiders of Gorumara National Park, Chapramari WildLife Sanctuary (Dist. Jalpaiguri) and Mahananda WildLife Sanctuary (Dist. Darjeeling), West Bengal, India. The study area falls within the eastern Himalaya, one of the global hotspots. It is worthwhile to mention that despite sincere efforts Indian spiders of the protected areas remained unexplored until the editors initiated studying the group since 1993. The monograph embodies taxonomic account and distribution of the species recorded from different ranges of these reserve forests.
