Burmacoccus is an

monotypic family Burmacoccidae, containing a single species, Burmacoccus danyi. The genus is solely known from the Albian – Cenomanian Burmese amber deposits.[1][2]

History and classification

Burmacoccus is known from the

London, England.[1] The amber specimen was recovered from deposits exposed in the Hukawng Valley of Kachin State, Myanmar. Burmese amber has been radiometrically dated using U-Pb isotopes, yielding an age of approximately 99 million years old, close to the Aptian – Cenomanian boundary.[2]

The holotype was first studied by paleoentomologist and coccid researcher Jan Koteja, of the Agricultural University of Kraków. Kotejas 2004 type description of the family, genus and species was published in the Journal of Systematic Palaeontology. He coined the specific epithet danyi to honor the Lebanese amber researcher Dany Azar, who assisted Koteja with fossil coccid research. The family name is a derivative of the genus name Burmacoccus, its self a derivation of Burma, the former name of Myanmar, and "coccus" a common genus name suffix for scale insects.[1]

Burmacoccus is one of three Burmese amber coccid genera that Koteja described in the same paper, the other two being

Grimaldiella, Kukaspis, Marmyan, Palaeosteingelia, Palaeotupo, Solicoccus, Turonicoccus and possibly Pennygullania, all with simple rows of eyes, were found to form a clade that included Burmacoccus. The clade also includes the modern families Putoidae, Steingeliidae and Pityococcidae plus the neococcoids clade as a group.[3]

Description

The single described adult male is approximately 1,300 μm (0.051 in) long, with hyaline wings. The details of the head are not readily discernible, being obscured by one wing, but the eyes are clearly composed of approximately fifteen ommatidia grouped into a compound eye. The antennae are composed of ten segments, with the

microtrichia, and a small but distinct lobe which couples with the hamuli. The hind-wings are modified into elongated halteres bearing two developed hamuli. The abdomen is conical in outline, narrowing towards the tip, with two short setae and having a developed penial sheath. The sheath is divided into a basal rounded section and a narrow style with pointed end. The abdomen is translucent enough for the preserved testes to be visible.[1]
