Antennal segments I-III
Head & thorax
Meso & metanota
Meso & meta spinula
Both sexes fully winged. Body, legs and antennae light brown, tarsi yellow, tibiae yellowish distally; fore wings shaded. Antennae 8-segmented; segment I with paired dorso-apical setae; segments III–IV each with narrowed apex, sense cone forked; VI narrowed at base, VIII longer than VII. Head slightly wider than long; eyes with a few weakly pigmented facets; 3 pairs of ocellar setae, pair III long, arising within ocellar triangle. Pronotum with 2 pairs of long posteroangular setae, two pairs of posteromarginal setae, 24–30 discal setae. Mesonotum without campaniform sensilla anteromedially; median pair of setae near posterior margin. Metanotum irregularly reticulate medially; median setal pair near anterior margin, no campaniform sensilla. Meso- and metathoracic spinula both well-developed. Fore wing with 2 setae on distal half, near apex, second vein with about 15 setae. Abdominal tergites without ctenidia or craspeda; II–VII with no sculpture lines medially, no microtrichia on lateral sculpture lines; tergites VI–VIII with median setal pair more than 0.5 as long as median length of tergite, VIII with complete comb of long, fine microtrichia; IX with 2 pairs of campaniform sensilla, X with short median split. Sternites without discal setae, setae S1 on VII arising in front of margin.
Male similar to female but smaller; Antennae 8-segmented, segment VI longer than combined length of I–V, with numerous long setae but without microtrichia; sternites with discal setae, but without pore plates.
The genus Mycterothrips, with 27 species worldwide, is primarily but not exclusively Holarctic (Masumoto & Okajima, 2006). Five species are known from Europe, with two more in the wider Mediterranean area (zur Strassen, 2003). M. consociatus is one of the species in this genus in which the antennae are sexually dimorphic, in contrast to the other two species recorded in Britain, latus and salicis.
Feeding and breeding on leaves, but probably pupating at ground level. In Britain found particularly on Betula [Betulaceae], but in Europe it has also been recorded from Alnus and Corylus [Betulaceae], as well as Salix species [Salicaceae].
In Britain taken rarely, mostly in southeast England but also Norfolk and Yorkshire (Mound et al., 1976; Collins, 2011). This species appears to have a Euro-Siberian distribution, extending to China and Japan (Mirab-balou et al., 2011).
