This species differs from all other species of the genus by the combination of the presence of six lateral organs and the characteristic chaetotaxy and genitalia: males with 4 + 4 thickened secretory setae (a) and only one seta (s) on sternites IV-VI; different ventral opisthosomal chaetotaxy in both sexes; the presence of strongly developed fusules on very long dilated digitiform processes in male genitalia; and the shape of genitalia in females.
1, habitus (dorsal, holotype); 2, habitus (dorsal, allotype); 3, abdominal sternites I-V (holotype); 4, last antennomeres of male (holotype); 5, left antenna of female (allotype); 6, male genitalia (holotype); 7, apex of penis (median lobe, lateral); 8, abdominal sternite IX; 9, abdominal sternite VII; 10, abdominal sternite VIII.
Female terminalia: Segment 7 longer than 6, ventrally-directed downward; sternite 7 trapezoidal; sternite 8 brownish-yellow, subdivided; hypoproct shiny orange, with 2 small fine setulae; cercus dark brown, long setulose; 3 brown sclerotised spherical spermathecae present.
Sternites moderately sclerotized; IV-X divided; posterior margin of each with many microlyrifissures; chaetotaxy 10: 16: 14: 15: 16: 17: 17: 12: 2.
the shape, maculae and setation of abdominal sternites 4 and 5 are virtually identical, the apical region of the basiphallus is markedly expanded in both species, with very similar left and right raised keels and both share the raised and spinose right sclerotised area of the basiphallus.
Abdomen: tergites not divided, medial sternites with very thin medial suture line; sclerites uniseriate.
Sternites uniformly blackish, silver-grey pruinose, white setose.
Sternites: densely granulose throughout; sternites VI-VII with paired paramedian and lateral carinae, incomplete and granulose; booklung spiracles short and oval.
Moreover, one morpho-species can be easily separated from the others by the presence of enlarged male antennomeres 7, anterior frontal fovea on the anterior-dorsal aspect of the head, and the absence of basolateral fovea on abdominal sternites V-VI.
