Diagnosis

Female macropterous; body color mainly dark brown, with trochanters, knees and tarsi yellow; antennal segment I brown, II brown with apex yellowish, III–VII yellow, VIII brown with yellowish base; both wings are yellowish brown with a dark median line. Antennae 8-segmented, antennomere III with 2 sense cones; only segment I with a stout setae with rounded tip. Head longer than wide, with a projection ahead of eyes; lateral margins slightly sinuous, with two pairs of stout setae arising from tubercles; two pairs of long and capitate setae dorsally: a postocular pair and a median pair; maxillary stylets parallel to each other, about half of head width apart, extending to the dorsal median setae. Pronotum with 5 pairs of well-developed and capitate setae, epimeral and posteroangular pairs the longest; prosternal basantra absent. Metanotum elevated anteriorly, with a pair of long median setae. Metathoracic sternopleural sutures absent. Pelta hat-shaped, anterior margin rounded and with lateral wings, covered in reticulation; abdominal tergites reticulated laterally and anteriorly, II–VII with 1 pair of wing-retaining setae. Tube cylinder-shaped, about 8.3x as long as basal width, with many lateral setae. Fore legs similar to other legs, fore femora with long setae, fore tarsi without a tooth. Fore wings with about 2–4 duplicated cilia.

Male macropterous. Similar to female, but the elevation in the metanotum forms two long tubercles, and a fore tarsal tooth is present. Pore plates absent.

Intraspecific variation

Unknown.

Genus and similar species information

Cyphothrips is a genus with two species and is exclusively subtropical. The species in this genus have the abdominal segment X very elongated and covered by stout setae, a pair of elongate tubercles on metanotum, and the head has an unusual pair of ventral tubercles, similar to small ommatidia. The genus Cyphothrips is closely related to the Neotropical genera Actinothrips, Zactinothrips and Zeugmatothrips. Zeugmatothrips species can be distinguished from Cyphothrips for lacking duplicated cilia in the fore wings or a fore tarsal tooth in males. Females of Actinothrips and Cyphothrips are very similar in general appearance, and the recognition of these genera can be difficult in the absence of males for study. Cyphothrips dorsalis is distinguished from C. longifrons by the fully brown body, head with projection ahead of eyes shorter and metanotal tubercles smaller and without denticles.

Distribution around the world

Life history

Specimens from the type series were collected from dead leaves of assai (Euterpe oleracea), where they probably feed on fungal spores.

Economic importance
