Yeshwanth, H. M., Chérot, F. & Henry, T. J., 2021, The Isometopinae (Hemiptera: Heteroptera: Miridae) of India and Sri Lanka: A Review of the Subfamily, with Descriptions of Six New Species, Zootaxa 4903 (2), pp. 151-193 : 168

Myiomma belavadii , n. sp.

( Figs. 3 C–D, 6K, 15A–H, 20C)

Diagnosis. Recognised by the pale brown dorsal coloration, the white spot on the cuneus, the red markings along the cuneal fracture, and the structure of male genitalia.

Type material. Holotype (³): INDIA: Karnataka, Bengaluru , GKVK, 23.i.2020, ex: Pongamia pinnata bark, Yeshwanth H.M. leg. ( UASB) . Paratypes ( 4♀), same data as for holotype .

Description. Male. Small, oval, elongate, length 2 mm. Colouration: Head with reddish-brown eyes, face with reddish or dark brown markings below eyes; apex of antennal segment II pale brown, segment III and IV reddish brown or dark brown. Dorsum pale brown, with mesoscutum pale yellow; cuneus with white spots and apex dark brown or black; margins of corium with a reddish tinge. Hind tibia with pale and dark brown bands. Abdomen ventrally dark brown. Surface structure and vestiture: Body finely punctate. Pronotum and hemelytra with goldenyellow, shiny, flattened setae. Head rounded in front, with outer margins of eyes elongate; ocelli proximate; eyes holoptic. Antenna arising slightly below the ventral margin of eye laterally; segment I short, tubular; segment II longest, cylindrical; segment III and IV subequal in length; segment IV bulbous. Labium long, surpassing hind coxa and extending to at least 8 th abdominal segment. Pronotum with a flat, carinate lateral margin, weakly curved; posterior margin deeply concave on either side of middle. Mesoscutum raised, width slightly less than head width in dorsal view, with two lateral raised sulci on margin; scutellum raised, equilateral. Metathoracic scent gland evaporatory area large, with prominent opening ( Fig. 15B ). Hemelytron with lateral margin weakly curved; cuneus triangular, slightly longer than wide at base, with a prominent cuneal fracture; membrane with a single cell. Legs with all femora swollen; hind femur greatly enlarged; tibia elongate; tarsi 2 segmented. Male genitalia: as in Figs. 15 C–H.

Female similar to male but slightly paler. Detailed measurements in Table 1 .

Distribution. India ( Karnataka).

Biology. Collected on the bark of Pongamia pinnata (L.) Pierre ( Fabaceae ).

Etymology. It is our pleasure to name this new species after Prof. Vasuki V. Belavadi (Department of Entomology UAS, GKVK, Bengaluru), a pollination biologist who provided support and encouragement to the first author during his studies on Miridae .

Discussion. This new species is separated from other Indian Myiomma species by the characters mentioned in the diagnosis and the key, mainly the total length, dorsal coloration, and male genital structures.
