Diagnostic features.
Body (except antenna) uniformly dark brown; maxillary stylets not retracted to po level; one pair of long setae on epimeral region; metanotal sculpture thoroughly striate; pelta anterior margin forming an acute tip, sculpture with thin reticles medially, bearing internal markings; males with pore plates on sternites VII– VIII, two anteroangular plates and a transverse posterior band, which is largely interrupted medially on VII; female spermatheca not enlarged.
Comments.
This dark brown species is known only from the
type
series collected in leaf-roll galls of
Myrcia retorta
(
Fig. 4
) in Southern
Brazil
(
Jorge
et al.
2016
). The head is about 1.4 times as long as wide and the maxillary stylets are wide apart and retracted to basal third of head length (
Fig. 258
). The anteromarginal setae are very short and the metanotum is characteristic in having longitudinally striate sculpture (
Fig. 260
). Larvae are largely white, but with bright transverse bands of red internal pigmentation on thorax and abdomen. The general body structure of
H. striatus
resembles the Peruvian species
H. orites
, but is distinguished from that by the overall smaller body size, absence of internal markings on mesonotal sculpture, and female spermatheca not being swollen medially. Other dark-bodied
Holopothrips
species, such as
H. atlanticus
,
H. nigrum
and
H. nigrisetis
also have some similarities, but
H. striatus
is distinct from these species in lacking the second pair of major ep setae (
Fig. 259
).
