Species Recognition

General information about the genus Caliothrips:
Members of this genus are dark brown, contain heavy net-like sculpture with internal markings, have banded wings and 8 antennal segments. Most of the species in this group are found living in grasses and legumes.

Typical character states of Caliothrips phaseoli:

Body color
Mainly brown

Number of antennal segments: 8
Segment IV - forked sensorium: extending to a point at least 30% distal to base of segment V
Segments III & IV sensoria: emergent and forked
Terminal antennal segments: very long, needle like

Head shape between compound eyes: not prolonged
Sculptured reticles on head and pronotum: with internal sculptured markings
Surface of head, pronotum and fore legs: with strong reticulate sculpture, but sometimes irregular
Head posteriorly: not constricted

Number of pairs of elongate pronotal setae: 0-3
Number of pairs of elongate posteroangular pronotal setae: 0
Sculptur of pronotum: without transverse striate sculpture

Mesothoracic endofurca: without median spinula

Metanotum: with campaniform sensilla
Metanotum median area: with at least some equiangular reticulation
Metanotum sculpture: without dominant sculptured triangle medially
Metathoracic endofurca: elongate and lyre-shape

Wings: present and more than half as long as abdomen
First vein of forewing: close to or fused to costal vein
Forewing anterior margin: with setae and cilia but setae longer than cilia
Forewing color: alternating bands of dark and light
Forewing costal setae at middle of wing: longer than median width of wing
Forewing first vein setal row: incomplete, with setae not closely and uniformly spaced
Forewing posterior margin cilia: undulated near apex
Forewing second vein setal row: complete, with setae closely and uniformly spaced
Forewing surface: not reticulate
Forewings: with veins, setae and microtrichia

Mid and hind tarsi: with one segment

Abdominal segment X: never tubular, longitudinally incomplete ventrally in both sexes
Abdominal tergites: without curved wing-retaining setae
Abdominal tergites IV & V median setal pair: much shorter than distance between their bases
Setae on abdominal tergite X: slender
Tergite VIII posteromarginal comb of microtrichia: present laterally, incomplete medially
Tergites III to VI sculpture on lateral thirds: comprising mainly transverse parallel lines



Life history:
Probably similar to the longevity of Caliothrips fasciatus larvae ranging from 0-14 days and adults ranging from 7-15 days both dependent on temperature (Lewis 1973).

Host plants:
Beans, cotton, soybean, sunflower

Vector capacity:
None identified

Current known distribution:
Central and South America, North America

Additional notes:
Caliothrips braziliensis is similar in form to C. phaseoli species and is found in Central America through Ecuador and Argentina.
