Melanthrips nigricornis Bagnall 



Malanothrips [sic] nigricornis Bagnall, 1913I1 : 263-264. 

 Melanothrips [sic] thymicola Bagnall, 1934c : 486-487. Syn. n. 

 Melanthrips nigricornis Bagnall ; Titschack, i960 : 29. 



This species belongs to the group of Melanthrips which have no cilia on the costal 

 margin of the fore wing between the bases of the two cross veins. The wing is not 

 lighter at the base as it is in fuscus. M. pallidior Priesner is closely related and may 

 prove to be a smaller and more common form of this species. Bagnall described 

 thymicola from two male and two female specimens, all mounted under one cover- 

 glass and in poor condition. These were said to differ from nigricornis in possessing 

 a long subapical hair on the hind tibiae. However this hair is present, although 

 not so elongate, in the paratypes of nigricornis.

MYMAROTHRIPS Bagnall 



Mymarothrips Bagnall, 1928a : 306. Type-species M. ritchianus, by monotypy. 



Bagnall erected a new family and superfamily of Thysanoptera for this genus, 

 although these groups are no longer used. The wings are narrowed basally and 

 greatly expanded subapically. The microtrichia of the submedian part of the wing 

 are very reduced and the costal setae are long. The antennal segments are short and 

 broad, almost quadrate, with numerous setae, and the maxillary palps are multi- 

 segmented. The genus is probably derived from Allelothrips like Aeolothripids, in 

 which group the antennal structure is highly variable between species and the 

 maxillary palps are often much divided.

RHIPIDOTHRIPIELLA Bagnall 



Rhipidothripiella Bagnall, 1932c : 292-293. Type-species Rhipidothrips turneri Moulton, 

 1930a : 197-198, by monotypy. 



The single species for which this genus was erected is more closely related to 

 Allelothrips than to Rhipidothrips. However the fore wings are not as Bagnall 

 stated ' as in Allelothrips ' , although the costal setae are well developed the wing is
