<p class="HeadingRunIn"><strong>Genus <em>Trichocera</em> in Morocco: first records from Africa and a new species (Diptera: Trichoceridae)</strong></p>

Abstract

Till now only two species of the genus Trichocera, T. annulata and T. hiemalis, were recorded from north Africa. Herewith, we document seven species from Morocco, which extend distribution of the genus and the family to most southern localities of the western Palearctics in Africa (mountain ranges: the Rif, Middle Atlas and Beni Snassen). The following species were found: one new species in the nominate subgenus Trichocera (Trichocera) marocana, n. sp., and six of the subgenus Trichocera (Saltrichocera) (saltator, sardiniensis, pappi, annulata, regelationis, rufescens). The remarkably high share of the regelationis group of species in this southern fauna is discussed in view of tolerance of these species to warm climate.

New records of Trichoceridae (Diptera) from the island of Mallorca ​

“…Specimens of T. saltator from Mallorca have around 30 setae on the ventral side of Sc vein, which is a case similarly observed in males of T. pappi Krzeminska, 2003 from Morocco (Driauach et al 2015). However, in other characters the Mallorcan specimens agree with T. saltator , including wing venation not typical for T. pappi and the species-specific male gonocoxal bridge and aedeagal complex (Fig.…”

“…Trichocera annulata is widespread in the Mediterranean region, with records from Algeria (Edwards 1923), Asia Minor and Ethiopia (Dahl and Alexander 1976), Malta (Ebejer 2015), Morocco (Driauach et al 2015) and Sardinia (Petrašiūnas 2009). Along with our data from Mallorca, these records suggests that this species has an unusually high tolerance to warm temperatures within the genus Trichocera .…”

Some winter active flies from snow and caves of Vârghiș, Romania

“…One of the most abundant species widely distributed in the Holarctic Region, and known also from North Africa (Morocco) (Driauach et al, 2015;Krzemiñska, 2021). Adults occur during autumn, winter and spring months (Krzemińska & Brunhes, 1991).…”

The first record of Trichocera (Saltrichocera) annulata (Diptera: Trichoceridae) in Romania, with additional data on Trichocera (Saltrichocera) maculipennis

“…The species is characterized by spotted wings, with uniform or banded abdomen (Volonterio et al 2013, Petrašiūnas andPodenas 2017). It also tolerates warmer temperatures and occurs from Arctic to the Mediterranean region, from Greenland to Japan and was also introduced to some Southern Hemisphere Islands (Dahl and Alexander 1976, Volonterio et al 2013, Driauach et al 2015, Petrašiūnas and Podenas 2017, Potocka and Krzemińska 2018. The only known record from Romania is from Tășnad (Tasnád), reported 120 years ago by Thalhammer (1900).…”
