Name
Leenurina Najt & Weiner, 1992 – Wikispecies link – Pensoft Profile
Type species:
Leenurina jasii Najt & Weiner, 1992
Diagnosis
Body wide, flattened dorso-ventrally. Thoracic tergum I fused to head. Suture between abdominal tergum IV and V normal or as a shallow inverted V. Integument strongly granulated dorsally, with tertiary granulations variously arranged and underlying of hexagonal regular reticulations on head, thorax II and III, and abdomen I to V. Eyes and postantennal organ located dorsally. Postantennal organ made of 9-14 entire vesicles in one row. Mandibles with five teeth, maxillae thin. Labial organite x present. Papillated chaeta L absent on labium. Antenna with distinct apical vesicle. Antenna IV with 6 thickened sensilla and one microsensillum dorsally. Dorsal chaetotaxy of short and pointed ordinary chaetae and thin s-chaetae. Chaetal arrangement strongly disrupted on head, with a large central area devoid of chaetae. Dorsal chaetotaxy reduced. Claw toothless. Furca reduced to two small swellings, each with one chaeta.
Discussion
On thoracic terga, p1 correspond to chaeta m1 of Najt and Weiner 1992[1], and p2 to p1. As a result, the s-chaeta is assumed to be in p4 (p5 as in Najt and Weiner 1992[1]). Leenurina differs from Caputanurina, the other genus of the subfamily Caputanurininae, by the characters listed in Table 1. Caputanurina intermedia Najt & Weiner, 1992 exhibits intermediate characters between the two genera, which are closely related.
