Abstract

The present work expands knowledge of 6 species of Blattodea under 5 genera belonging to 3 families, viz., Blattellidae, Blattidae and Blaberidae, represented by 3, 2 and 1 species, respectively, in the Kolhapur District, Maharashtra, India. These 6 species are Blatella humbertiana (Saussure, 1863), Blatella germanica (Linnaeus, 1767), Pycnoscelus surinamensis (Linnaeus, 1758), Periplaneta americana (Linnaeus, 1758), Neostylopyga rhomobifolia (Stål, 1813)and Supella (Supella) longipalpa (Fabricius). Supella (Supella) longipalpa was recorded for the first time and is a new addition to the fauna of Maharashtra state. Information on localities and dates of collection of all 6 species are provided.

Blattodea is one of the oldest insect orders with a fossil history extending to more than 300 million yr. They are small to medium sized, and the majority of them are nocturnal, but the species found on trees and bushes are diurnal. They are medically important, because they mechanically transmit food-, garbage- or water-borne pathogens. They have diverse habits, i.e., some are semiaquatic e.g., Blatta orientalis L. (Blattidae) and Neostylopyga rhombifolia (Stål, 1813) (Blattidae) (Shelford 1909), some are found among fallen leaves, on the surface of the soil, under stones, under bark, in thick grass among low vegetation, in debris and inside buildings; some species are cave dwellers and a few are myrmecophilus. Their morphology is very distinctive with a strongly depressed body, bilaterally symmetrical and dorsoventrally flattened.

Notable taxonomic works on Blattodea from India are the following: Kirby (1904), Shelford (1906), Hanitsch (1915), Bruijning (1948), Rehn (1951), Princis (1966, 1971), Mukherjee (1989), and Roth (1996). In addition, Mandal (2007) reported 14 species under 13 genera and 5 families from Andhra Pradesh. Mandal (1995) reported 26 species under 20 genera and 5 families from Meghalaya. From Sikkim Mandal (2003) reported a total 17 species under 13 genera and 5 families. Mandal et al. (2000) reported the occurrence of 10 species under 8 genera from Tribura. Mukherjee (1993 enumerated 23 species under 16 genera of 10 families from West Bengal. Under the fauna of Tamil Nadu, Prabakaran (2009) reported 47 species under 32 genera and 5 families. Jadhav & Sharma (2012) reported 12 species under 10 genera and 4 families from Maharashtra.

There are 4,000 known species worldwide belonging to the 6 above-mentioned families (Roth 1999, 2003) under 445 genera. Out of these, a total 156 species and 57 genera in 5 families are reported from India (Mandal 1995, 2000). According to the fauna of Maharashtra (2012) there are 12 species belonging to 10 genera occur in Maharashtra. However, Nesemann et al. (2010) recorded 2 species Rhicnoda natrix and Rhicnoda rugosa from Maharashtra, which are not included in the fauna of Maharashtra (Jadhav & Sharma 2012). During the present study the species, Supella (Supella) longipalpa, was recorded for the first time from Maharashtra. The total tally of Blattodea species in Maharashtra has increased to 15 species belonging to 12 genera.

In the present study, 6 species in all are reported representing 5 genera under 3 families and 4 subfamilies, which are distributed in Kolhapur District, Maharashtra (Plate 1). The Blattellidae is the dominant family in the study area and is represented by 3 species, while the Blattelidae and Blaberidae are represented by 2 and 1 species, respectively. The species reported in this region are briefly described. The information on taxonomy of these species is scanty; hence the species reported from this region are described with photographs.
