Two New Fruit Fly Species Discovered in Himachal Pradesh’s Himalayan Foothills

Scientists Identify New Fruit Flies and First Record of Rhagoletis in India

Researchers have identified two previously unknown species of fruit flies and documented an insect group never earlier recorded in India during a scientific survey in the Himalayan foothills. The study was carried out in the Solan region of Himachal Pradesh by entomologist Maneesh Pal Singh and British scientist David Lawrence Hancock . Their research expands scientific understanding of the fruit fly subfamily Trypetinae and highlights the biodiversity richness of the Himalayan ecosystem.

Field Surveys and Research Methods

The discoveries were made during detailed field surveys conducted in the Solan region. Scientists collected specimens using sweep nets along with a specialised attractant called Solan Bait , designed to lure female fruit flies. After the fieldwork, laboratory analysis was conducted using microscopes to study wing patterns and reproductive structures. These examinations confirmed that some of the collected specimens represented species not previously documented in the country.

Newly Identified Species

One of the new species has been named Acidoxantha paratotoflava . This medium-sized insect has a greenish-yellow body with four black stripes on its thorax and distinctive dark markings on the abdomen. Unique hook-shaped features in the male reproductive organs helped researchers confirm it as a separate species.

The second species, Hemilea suneriae , has a reddish-brown body covered with small black spots. Its most notable characteristic is an unusual wing design containing a single transparent patch, known as a hyaline window, within a darker wing area.

Additional Scientific Findings

The research also documented the insect genus Rhagoletis in India for the first time. Members of this genus are globally recognised for their association with fruit crops. In addition, scientists identified the male specimen of Euphranta nigripeda , a species first described in 1913 but previously known only from female specimens. The Bombax ceiba was recorded as one of the host plants for some of the studied fruit flies.

Exam-Focused Key Points

• Trypetinae: Subfamily of fruit flies within the Tephritidae family.

• Rhagoletis: Recorded in India for the first time during this study.

• Bombax ceiba: Identified as a host plant for certain fruit fly species.

• Euphranta nigripeda: Species described in 1913 , male specimen documented recently.

• Himalayan foothills are recognised as a biodiversity hotspot with many unexplored species.
