Type material: male, Holotype: Panama: Panama Prov., Miramar (- 82.19°W, 8.95°N), car net, 30.7.2014, leg. T. Struyve ( UIC). Paratype: female, with same data as holotype ( TSC) GoogleMaps .
Diagnosis: Only a single species of the genus is represented in the Neotropics. It can be easily differentiated from all Neotropical species of the genus Eleusis by the short and wide head with distinctly separated clypeus, the extremely posteriad widened shape of the elytra, and the absence of grooves in the anterior angles of the pronotum. Moreover, the structure of the parameres differs from all other Neotropical species by the absence of a widened apical transparent lobe.
Description: Length: 2.3 mm. Colouration: black, elytra yellow with dark spot at scutellum and indistinctly black posterior margin; clypeus light brown; posterior margin of abdominal segment slightly lighter than base; legs dark brown with light brown spot at femortibial connection; antennae light brown.
Head: 0.24 mm long, 0.58 mm wide; eyes prominent; slightly shorter than temples; temples continuously narrowed posteriad; without separate neck; no sexual dimorphism; antennae inserted directly in front of eyes; between base of antennae with transverse ridge separating vertex from lower elevated clypeus; front margin of clypeus straight; without supraocular groove and setiferous punctures; punctation coarse and dense; on average, interstices between punctures as wide as diameter of punctures; between coarse punctation with micro-punctation; along midline impunctate or less densely punctate; without microsculpture; surface polished.
Antennae as long as head and pronotum combined; first antennomere thicker and longer than following antennomeres; curved; second antennomere one third as long as first and shorter than third; following antennomeres approximately equally long and wide; slightly longer than wide; antennomeres four to eleven weakly pubescent and with few long apical setae.
Pronotum: 0.33 mm long, 0.50 mm wide; widest close to anterior angles; anterior angles obtuse; in anterior half narrowed in smooth curve; in posterior have strongly narrowed to obtuse posterior angles; posterior margin 0.43 times as wide as anterior margin; lateral margin slightly interrupted in posterior third; punctation as deep than on head, but less dense; on average, interstices twice as wide than diameter of punctures; without setiferous punctures at anterior or lateral margin; without microsculpture; surface polished.
Elytra: 0.63 mm long, 0.68 mm wide; widest at posterior angles; distinctly convergent to humeral angles; at humeral angles 0.6 times as wide as at posterior angles; posterior margin smoothly rounded; triangularly retreated to suture; punctation extremely weak and sparse; without microsculpture; surface polished.
Abdomen polished; without microsculpture and punctation.
Aedeagus extremely depressed; central lobe with transverse rows of sensillae in apical half; parameres shorter than central lobe; without apical transparent widening.
Etymology: The species name is a combination of the Greek epithet platy meaning broad and soma meaning body and refers to the broad body.
