Neolinoptes gen. n.

Linoptes Gorham, 1884: 247 - syn. n. [preoccupied by Linoptes Menge, 1854: 94 (Arachnida: Araneae)].

Type species. Linoptes imbrex Gorham, 1884 .

Etymology. derived from the Greek word “ neo” (new) and the generic name Linoptes . The gender is masculine.

Distribution. Central and South America (Nicaragua, Panama, Peru and Brazil)

Comments. Menge in Koch & Berendt (1854) proposed a new spider genus, Linoptes Menge, 1854 from Baltic Amber in a footnote. Wunderlich (1986) synonymized Linoptes Menge, 1854 to Deinopis MacLeay, 1839, but later Wunderlich (2004) considered Linoptes Menge, 1854 as nomen nudum. Although Menge´s (1854) definition of the spider genus Linoptes is extremely brief, the name satisfies the provisions of the Article 12.1. of the ICZN (1999). Consequently, Linoptes Gorham, 1884 was discovered to be a junior homonym and therefore, here we propose a new replacement name for the lycid genus Linoptes Gorham, 1884 . Additionally, all 4 species of the lycid genus Linoptes Gorham, 1884 and Calocladon rubidum Gorham, 1884 are transfered to Neolinoptes .

Diagnosis. This species is easily distinguishable from the other species by the coloration and genitalia shape.

Redescription. Eyes medium, interocular distance 1.5 times longer than eye diameter. Antennomere 5 as long as 4, 1.3 times longer than 3 (Fig. 6). Mandibles stout, curved. Labial palpi small, terminal palpomere broad. Maxillary palpi elongate, palpomere 2 as long as 4 and 2.5x longer than 3, palpomere 4 obliquely truncate apically. Labrum slightly rounded distally. Anterior thoracic spiracles short. Pronotum dark brown with lateral sides testaceous, as long as wide medially, arcuately produced anteriorly, widest at basal margin, posterior angles sharp. Pronotum presenting strong median longitudinal carina with slender lenticular areola at basal ¾, posterior margin bisinuate (Fig. 5). Scutellum with median emargination apically. Elytra testaceous, elongate, 4 times longer than humeral width. Each elytron presenting 9 longitudinal costae with irregular cells, costae 2 and 4 strong, secondary costae weak. Prosternum triangular, mesosternum transverse, trapezoidal. Abdominal sternum 8 with median rounded emargination distally. Abdominal sternum 9 elongate proximally, pointed. Trochanters dark brown, elongate, conical, as long as third of femur length. Femur dark brown, tibiae dark brown, as long as femur.
