New Insect Biodiversity: Acidoxantha Paratotoflava and Hemilea Suneriae Discovered in India

Recently, a novel species of fruit flies, Acidoxantha paratotoflava and Hemilea suneriae, have been found in the foothills of the Himalayas in Himachal Pradesh, which has been a valuable addition to the insect biodiversity of India.

This discovery of Indian and British entomologists highlights the ecological richness of the area that is yet to be tapped.

How was this Species Discovered?

Field surveys in the Solan district of Himachal Pradesh were done by entomologists Maneesh Pal Singh of the College of Horticulture and Forestry (Nauni University) and David Lawrence Hancock. 

They utilized sweep nets and a special female attractant known as Solan Bait to trap the specimens and then inspect them under the microscope in the laboratory in relation to wing patterns and reproductive structures. 

They were formally described as the two new species of Trypetinae subfamily in the journal Zootaxa (Volume 5760, Issue 5).

What Does the Species Look Like?

Acidoxantha paratotoflava is a medium-sized fly with four black stripes on its thorax, larger black marks on the abdomen and hook-like features in the male genitalia. It is similar to A. totoflava which may have been mistaken for previous records in India. 

Hemilea suneriae, after the late mother of the researcher, Verma Suneri, is reddish-brown, with black dots and a single hyaline (transparent) window on its wing, compared to the normal two in its family.

Additional Findings

It was the first documentation of the genus Rhagoletis, recognized worldly to affect fruit crops, in India, one of the species being close to R. freidbergi. It also discovered the hitherto unknown male of Euphranta nigripeda, described in females in 1913. 

Some species were characterized by their host plants such as the Silk Cotton tree (Bombax ceiba).

Biodiversity Meaning

The findings suggest the under-researched insect diversity of the Himalayan foothills and threats of fruit flies in agriculture. They are part of the Tephritidae taxonomy on the planet, and type specimens are held in the High Altitude Regional Centre of the Zoological Survey of India at Solan. This kind of research helps to control the pests and preservation of the northern ecosystem in India.
