Genus Ordgarius Keyserling, 1886 is known from India to Japan and Indonesia, as far as India is concern 03 species were reported (ISC, 2015). Present paper deals with the specimens collected from Agroecosystem of Agriculture University, Navsari, Gujarat-India. Specimens were collected during both summer and rainy seasons from Banana and Papaya crops. This paper describes the species from genus Ordgarius, along with rediscription and diagnostic characters.

A brief redescription to recognize the species and information about natural history are given. Finally, with the new records we evaluated the potential distribution of this species in the country. Key words: Atacama Desert, new records, spiders. Resumen. Se amplía la distribución conocida para la especie Mastophora gasteracanthoides hacia el norte de Chile. Se entrega una breve redescripción para reconocer a la especie e información acerca de su historia natural. Finalmente, con los nuevos registros evaluamos la distribución potencial de esta especie en el país. Palabras clave: Desierto de Atacama, nuevos registros, arañas. The genus Mastophora (Holmberg, 1876) is represented by 49 described species in the Americas (World Spider Catalog 2018). This genus comprises a small group of spiders that are notable for their curiously formed and sculptured bodies (Gerstch 1955; Levi 2003). -
