Elephantomyia (Elephantomyia) bozenae is an extinct species of crane fly in the family Limoniidae. The species is solely known from the Middle Eocene [1] Baltic amber deposits in the Baltic Sea region of Europe. The species is one of six described from Baltic amber. [2] [1]

History and classification

Elephantomyia (Elephantomyia) bozenae is known only from the holotype specimen, collection number MP/3338, which is preserved as an inclusion in transparent Baltic amber. As of 2015, the amber specimen was included in the collections of the Polish Academy of Sciences. [2] Baltic amber is recovered from fossil bearing rocks in the Baltic Sea region of Europe. Estimates of the age date between 37 million years old, for the youngest sediments and 48 million years old. This age range straddles the middle Eocene, ranging from near the beginning of the Lutetian to the beginning of the Pribonian. E. bozenae is one of six crane fly species in the genus Elephantomyia described from the Baltic amber, the others being E. baltica , E. brevipalpa , E. irinae , E. longirostris , and E. pulchella . [2] All six species are placed into the Elephantomyia subgenus Elephantomyia based on the lack of tibial spurs and by several aspects of the wing morphology.

The type specimen was first studied by paleoentomologist Iwona Kania, of the University of Rzeszów, whose 2015 type description for the species was published in the journal PLoS ONE. The specific epithet bozenae was coined to honor the biologist Bożena Szala. [2]

Description

The E. bozenae type specimen is a well preserved male that is approximately 3.1 mm (0.12 in) long, not including the rostrum. The head has a rostrum that is 2.14 mm (0.084 in) long, just over half the length of the fore-wing and longer than the abdomen. The tip of the rostrum has elongate palpus at the tip. Each palpus is composed of four segments, with the basal three segments long and the apical segment short. All four segments host a system of microtrichia. The antennae are small, composed fifteen segments. They have an elongated scape and widened pedicle. As the flagellomeres progress from the base to the tip of the antennae they change from squat and crowded together to elongated and the apical segment is widened at the tip. All of the flagellomeres host two setae each. The wings are 3.56 mm (0.140 in) long with a pale brown pterostigma that is oval in shape. The D cell, as designated by the Comstock–Needham system, is notably elongated and narrowed, in comparison to all other Baltic amber Elephantomyia. [2]

Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1869.

<i>Yantaromyrmex</i> Genus of ants

Yantaromyrmex is an extinct genus of ants first described in 2013. Members of this genus are in the subfamily Dolichoderinae of the family Formicidae, known from Middle Eocene to Early Oligocene fossils found in Europe. The genus currently contains five described species, Y. constrictus, Y. geinitzi, Y. intermedius, Y. mayrianum and Y. samlandicus. The first specimens were collected in 1868 and studied by Austrian entomologist Gustav Mayr, who originally placed the fossils in other ant genera until the fossils were reviewed and subsequently placed into their own genus. These ants are small, measuring from 4 to 6 mm in length and can be characterized by their trapezoidal shaped head-capsules and oval compound eyes that are located slightly to the rear of the capsules midpoint, with no known ocelli present.
