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

Abstract

BackgroundThe Trichoceridae are a small family distributed mainly in the Holarctic Region, most of which are associated with cold seasons and even snow. From the Iberian peninsula, 5 species have been recorded; however only a single previous occurence record exists from the Balearic islands.New informationIn this paper we present new records of two species from Mallorca, of which Trichocera (Saltrichocera) saltator (Harris, 1776) has not previously been recorded from the Balearic islands. Trichocera (Saltrichocera) annulata Meigen, 1818 is recorded for the first time from Mallorca. We furthermore discuss the species' distributions within the Mediterranean region and report new morphological data for the Mallorca island form of T. saltator.

Survey of the families Anthomyzidae, Aulacigastridae, Odoniidae, Periscelididae, and Trichoceridae (Insecta: Diptera)

“…The first record for Mallorca and the second from the Balearic IslandsTrichocera annulata is widespread in the Mediterranean region, with records from Algeria, Asia Minor and Ethiopia(Dahl and Alexander 1976), Malta, Morocco and Sardinia. Along with our data from Mallorca, these records suggest that this species has an unusually high tolerance to warm temperatures within the genus Trichocera[60].…”

“…Membranous wings, long and narrow, with a large anal lobe. The abdomen is thin and cylindrical, in the male it has two processes equal to the caudal end, in the female it is fusiform and has an ovipositor generally curved downwards (Figures 10A-10C) [50][51][52][53]. The larvae are also found in the colder months throughout the year.…”

“…The coast stretches along the entire shore. The subnerve, close to the radius, is long and divides into two terminal branches: Sc1 is longitudinal and aligned with the base and flows into the rib, Sc2 is quite short, differs in a more proximal position, and takes on a transverse course, merging into R1 (Figures10A-10C)[53][54][55].A B CSources: file:///C:/Users/Lenovo/Downloads/Kolcsar_etal2018.pdf, https://pbase.com/tmurray74/crane_flies_family_trichoceridae and Author: Caroline Harding, Ministry for Industries, New Zealand.…”

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

“…From Europe, 2 genera were reported: Cladoneura Scudder, 1894 (= Diazosma Bergroth, 1913) and Trichocera Meigen, 1803(Kolcsár et al 2018. The widespread genus Trichocera comprises around 110 species (from a total of about 160 Trichoceridae species), distributed mainly in the Holarctic region (Petrašiūnas and Kvifte 2016). In Romania, this Diptera family was studied by Ujvárosi and Krzemińska (2002), who recorded 13 species of Trichoceridae new to Romania.…”

“…It is characterized by a distinctly banded abdomen and unspotted wings, with the d cell broad, pentagonal (Freeman 1950, Krzemińska 1999. Trichocera (Saltrichocera) annulata shows an unusually high tolerance to warmer temperatures, having a wide distribution in Africa (Ethiopia, Algeria), Asia Minor and the Mediterranean region as well (Dahl andAlexander 1976, Petrašiūnas andKvifte 2016). So far, it was recorded from North-America, Asia, Africa, most of the European countries (Dahl and Alexander 1976, Krzemińska and Brunhes 1991, Krzemińska 1999), but not from Romania, until now.…”
