Strobliellini

Jaschhof, Mathias, 2017, Catochini, Strobliellini and Acoenoniini revisited: a taxonomic review of the small tribes of the Micromyinae (Diptera: Cecidomyiidae), Zootaxa 4250 (3), pp. 275-295 : 286

Tribe Strobliellini Kieffer

Edwards (1938) was first to shed light on this enigmatic tribe, which at that time contained a single species, Strobliella intermedia Kieffer. Most important for subsequent students of Strobliellini , Edwards (1938: fig. 7) studied and figured the holotype male of S. intermedia , which now seems to be lost ( Jaschhof 1999). Another stroblielline genus, Groveriella , was introduced by Mamaev (1978), again for a single species, G. carpathica , known from a single male. A second species of Groveriella , G. baltica , was described by Spungis and Jaschhof (2000). These three species, of which G. baltica and S. intermedia are treated in more detail below, are apparently the only true Strobliellini . Both Amedia floridana Jaschhof and Amediella involuta Jaschhof should be regarded as provisionally classified in this tribe (see Jaschhof & Jaschhof 2009: 86); Eleniella kyseluci Berest was recently recognized as being identical with Monardia obsoleta Edwards , a species of Micromyini ( Jaschhof 2016) ; and Strobliella brachycornis Spungis & Jaschhof is a species of the genus Catocha , tribe Catochini , as shown above.

Morphological traits of adults (larvae are unknown) indicate that the phylogenetic position of Strobliellini is between Catochini and Campylomyzini ( Edwards 1938; Jaschhof 1998; Jaschhof & Jaschhof 2009: fig. 104). The fact that specimens of Strobliellini are rare items in museum collections complicates their analysis, which is demonstrated below using the example of Strobliella intermedia . The tribe is defined by the wing venation, which includes an unbranched M1+2 and a basally free M4 ( Jaschhof & Jaschhof 2009: fig. 15D), and by the augmented number of flagellomeres, which in both sexes is more than 14.
