Mellor et al., 2009). This species, first described by Kieffer (1910) from Puri, has since been reported in various parts of India (Prasad et al., 2009). The pupa was described by Mayer (1934) from Sumatra, whereas the egg, larva, and pupa were reported by Narladkar et al. (1991) without detailed taxonomy and illustrations based on recent terminologies. Based on adult morphology, Nandi (2014) revised the genus and recognized 11 species under the subgenus Hoffmania, including C. peregrinus. Light trap data revealing a high prevalence of this species in proximity to cattle (unpublished data) prompted us to describe all immature stages with modern terminologies based on scanning electron microscopy (SEM). This taxonomic information about the immature stages will help to precisely determine the oviposition sites, to specify larval habitats and the differentiation of larval instars, and ultimately to adopt effective control strategies against this vector species. This paper describes the ultrastructure of the egg and larval instars and offers a redescription of the pupa. Immature specimens of this species are presently recognized by the random arrangement of tubercles in two broad dorsoventral longitudinal rows of egg chorion, epipharynx combs 2 and 3 absent in larvae, and weak sclerotized band on the antennal sheath and presence of palpus tubercle in pupae. Materials and methodsWild adult females of Culicoides peregrinus were collected by operating a downdraft UV light trap (Harsha and Mazumdar, 2015a) within a cattle shed at Adisaptagram (22°56′50″N, 88°23′08.3″E), Hooghly district, West Bengal, India. The live engorged females oviposited after 48 h onto a wet filter paper within a glass vial (6.5 × 2 cm). Thereafter, the embryonated eggs (confirmed by the presence of eye spots) were reared in two different rearing media. Some eggs were placed in petri dishes, with absorbent cotton provided as a substrate and mud broth + 2% yeast solution provided as food in an environmental test chamber at 26 °C (model CHM-10S; REMI Elektrotechnik Limited, Vasai, India), following Harsha and Mazumdar (2015b). Similarly, cattle manure (natural breeding habitat) was bought to the laboratory and a few larvae and pupae were hand-picked from the cattle manure and were subsequently treated for description, while the rest of the cattle manure was kept for the adult emergence. A few of the embryonated eggs were processed for SEM after Day et al. (1997); for differentiation of instars, 6-7 larvae were extracted every day from the rearing dishes and mounted on slides following Das Gupta and Wirth (1968). The different larval instars were differentiated based on measurements and several ratios of the head capsule. Eggs, larvae, and pupae were also studied under a scanning electron microscope (model S5 30; Hitachi, Tokyo, Japan) at the Science Instrumentation Centre at the University of Burdwan. Similarly, larvae and pupae were Abstract: Detailed descriptions of the immature stages, i.e. eggs, larvae, and pupae, of Culicoides peregrinus Kieff...
A new genus, Chaudhuriomyia in the tribe Macropelopiini belonging to subfamily Tanypodinae is described and illustrated in all life stages. The genus can be distinguished from all the other known Macropelopiini by the presence of a blunt claw on fore leg and a smooth surface of tibial spur in adult male, seminal capsules without proper neck in adult female, round anal lobe in pupa, and slightly inwardly bent inner tooth of ligula in larva. Generic diagnoses for larva, pupa and adult are provided. Taxonomic position and distribution of the genus are discussed along with a new adult key of tribe Macropelopiini. The specimens were collected from a stream in Indo-Bhutan border area of Eastern Himalaya in Indian Subcontinent. A note on the ecology and biology of the new genus is included.
Immature and adult stages of Monopelopia mongpuense sp. n. from phytotelmata of Cedrus deodara (Lamb.) in Darjeeling are described along with biological notes. Key to the adult males of all species of the genus Monopelopia Fittkau is also presented. This genus is recorded for the first from Indian subcontinent.
Life stages of Palpomyia sohraensis sp. n. is described and illustrated with bio-ecological notes. Key to the adult of the all species from India of the genus Palpomyia Meigen is also provided. The complete life stages of any Palpomyia are described for the first time from the Oriental Region.
Life stages of Forcipomyia parasecuris sp. n. is described, illustrated and photomicrograph based on examination with scanning electron microscope and binocular microscope. The larvae were collected from rotting banana stump of a banana garden at lower Gangetic plain area in India. Absence of ocular sensillum and campaniform sensillum in ocular area of pupa, a synapomorphic character of this proposed new species exhibits its uniqueness in genus Forcipomyia. This is also the first life stage of any Forcipomyia described from India.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
