Holopothrips inquilinus (Bournier)

( Figs 120–121 )

Caraibothrips inquilinus Bournier, 1993: 236 .

Diagnostic features. Body mostly yellow, with head bicoloured and abdominal segments VIII–X fully brown; maxillary stylets parallel; two pairs of long setae on epimeral region; metanotal sculpture formed by weakly defined reticulation, without internal markings; males with three pore plates on sternites VII–VIII.

Comments. Originally described in Caraibothrips , this species is frequently misidentified as H. tabebuia due to its sharply bicoloured body ( Fig. 120 ). However, H. inquilinus can be distinguished by the presence of two pairs of long epimeral setae on pronotum ( Fig. 121 ) and the weakly reticulate sculpture on metanotum. Sternites VII– VIII of the male bear one posterior and two anterolateral pore plates. This thrips was described from Guadeloupe breeding inside empty cecidomyiid galls on leaves of Inga (Fabaceae) , and is also reported from Panama ( Goldarazena et al. 2012).

Material studied. 1 female paratype; Guadeloupe, Duclos , inside old Cecidomyiidae gall, 4.vii.1985 (Etienne,

M.J.), at BMNH.
