Type material: male, Holotype: Panama: Panama Prov., Santa Fé , Piedra Alta (8.52°N, - 81.13°W), dead wood, 26.4.2014, leg. T. Struyve ( UIC). Paratype: female with same data as holotype ( TSC) GoogleMaps .
Diagnosis: The species closely resembles E. frater in size, shape, and colouration. It is certainly the sister species of E. frater in Panama. It can be easily differentiated from E. frater by the microsculpture of the head and the elongate aedeagus. Whereas the head E. frater has only remains of microsculpture with large parts polished, the head of. E. panamaensis is totally covered by microsculpture. The head of E. panamaensis is impunctate, whereas the head of E. frater is distinctly punctate. The eyes are smaller and temples longer in E. frater than in E. panamaensis . The central lobe of the aedeagus is nearly twice as long in E. panamaensis as in E. frater .
Description: Length: 4.5 mm. Colouration: totally black; sides of abdominal segments lighter brown; legs light brown; antennae dark brown.
Head: 0.54 mm long, 0.57 mm wide; eyes large; slightly prominent; temples slightly shorter than eyes; behind eyes shortly parallel; posterior angles obtuse; preocular sides nearly as long as temples; anterior margin of frons continuously narrowed to short straight central part; central prominent part slightly emarginate; supraocular groove deep; anterior part parallel to side; slightly curved in posterior part; impunctate except setiferous puncture at each end of supraocular groove; another pair of setiferous punctures on each side of central clypeal prominence; elongate microsculpture weak, but dense; longitudinally striate; surface slightly matt.
Antennae slightly shorter than head and pronotum combined; first antennomere slightly thicker than following antennomeres; second antennomere only half as long as first; third slightly longer than second; following antennomeres decreasing in length and increasing in width; fourth antennomere triangular; slightly longer than wide; tenth antennomere 1.6 times wider than long; fourth to eleventh antennomere pubescent; all antennomeres with long apical setae.
Pronotum: 0.52 mm long; 0.59 mm wide; widest close to anterior angles; sides in anterior half parallel; in posterior half narrowed to posterior margin in even curve; anterior angles shortly rounded; at posterior margin, central part slightly prominent; prominent part marked by deep impression margined at inner side by ridge; close to anterior angles, at anterior margin two deep impressions with setiferous punctures; another deeply impressed setiferous puncture at beginning of posterior half and at posterior margin close to ridge; very finely and sparsely punctate; elongate microsculpture similar to that of head, but midline and few parts on disc without microsculpture; longitudinally striate; surface shinier than on head.
Elytra: 0.73 mm long, 0.73 mm wide; humeral angles shortly rounded; sides slightly divergent to widely rounded posterior angles; on each side of suture, posterior margin convex; punctation weak and sparse; similar to pronotum; along lateral margin with setiferous punctures; on each side of suture setiferous puncture on central disc; elongate microsculpture weak; with shiny interstices; transversely striate.
Abdomen finely punctate; each segment with transverse row of four setiferous punctures; elongate microsculpture weak; transversely striate.
Aedeagus elongate; apical part of central lobe much longer than basal part; in lateral aspect, apex acute, but obtusely rounded; in ventral aspect, central lobe parallel; apex widely rounded; sensillae concentrating along apical midline; at apex, denser than closer to base; parameres shorter than central lobe; transparent lobe narrow; with few sensillae.
Etymology: The species name derived from the country’s name Panama, where the species was collected by Tim Struyve.
