On two new species of earwig (Dermaptera) and a new record of Diplatys chinensis Hincks from India

Based on a collection of earwigs from Simla hills (Himachal Pradesh) and Kashmir, two new species, namely Diplatys srivastavai and Forficula meenae have been described and Diplatys chinensis Hincks is recorded from India for the first time.     

A new genus and two new species of aphids (Homoptera: Aphididae) from north-west India

A new aphid genus Raychaudhuriella and two new specices viz. Raychaudhuriella myzaphoides and Rhopalosiphoninus sensoriatus are described from Himachal Pradesh, north-west Himalaya. The affinity of Raychaudhuriella gen. nov. is drawn with Aspidophorodon Verma, Cavariela del Guercio, Myazphis van der Goot, Tricaudatus Narzikulov and Vesiculaphis del Guercio. Figures and biometrical data of the new species have been provided.     

Two new ectotroph-forming boletes from India

Pulveroboletus shoreae sp. nov. andXerocomus bakshii sp. nov. (Boletaceae) are described as new. Observations at the type locality show that they are both connected with short roots of the ectotrophic-mycorrhizal type, theXerocomus withPinus roxburghii, thePulveroboletus withShorea robusta, Fam. Dipterocarpaceae. This latter family has not been shown to form ectotrophs with ectotrophically mycorrhizal Basidiomycetes before our present research.     

Two new lecanid rotifers from India

While working on the material collected from Calcutta and its environs, the author came across two new lecanid rotifers which have been described in this paper as a new species and a new variety.     

Some ecological observations on two agarophytes from India

The responses of Gracilaria corticata and Gelidiopsis gracilis (agarophytes) to different concentrations of sea water, pH range and lights of different colours have been studied to understand the ecological amplitudes. Both algae had a very narrow range of salinity tolerance from 29.0 to 33.1. With respect to pH also, they could thrive only under pH values from 7.0 to 8.0. Growth of these algae was retarded under all coloured lights. However, under yellow light growth was nearer to that of controls.
