A new species of the gecarcinucid freshwater crab genus, Spiralothelphusa Bott, 1968, is described from the Andhra Pradesh State of South India, with supporting data from mitochondrial cytochrome c oxidase subunit I. This brings the number of known species of Spiralothelphusa to seven, five from India and two from Sri Lanka. The identity of S. wuellerstorfi (Heller, 1862) has remained uncertain because the former lectotype designation was not clear. Bott (1968), while designating a male lectotype of S. wuellerstorfi from the Naturhistorisches Museum Wien, Vienna, Austria, had neither stated the catalogue number nor the size of the specimen. It is now difficult to trace the particular lectotype among several paralectotypes of the depository. A new lectotype is, therefore, designated herein for S. wuellerstorfi, and the species is redescribed. The new species, S. andhra sp. nov., has morphological affinities with S. wuellerstorfi, but can be distinguished from the latter species by the shape of the male telson and outer margin of the non-twisted portion of the male first gonopod. Phylogenetic analyses of the molecular data also corroborate their separation. An illustrated identification key is provided for the species of Spiralothelphusa.

An annotated checklist of the Blattids of Maharashtra state is prepared based on the available literature and online database resources. Earlier studies has been made by (Jadhav and Sharma, 2012) listed that 12 species of Blattids from this state, in the present situation an updated checklist has been made to the Blattodea fauna includes 32 species comprises 4 family comes under 23 genera. Globally the Blattodea contains a total of 7570 species are recognized, of which 4641 species are cockroaches and 2929 species are termites has been listed (Krishna et.al., 2013). This 4641 species are accommodated under 492 genera belonging to 8 families. Among this, 170 species under 65 genera belonging to 5 families, so far reported from India (Prabakaran and Senraj 2018) (Excluding Epifamily: Termitoidae).The classification followed here as after Beccaloni & Eggleton 2013.
