Enderleina yoshikii new species

( Figs. 11–13 )

Enderleina flinti: Ribeiro & Rafael (2005) [misidentified]; Derka et al. (2019) [species distribution]

Type Material. Holotype, Material examined: BRAZIL, Amazonas state, Santa Izabel do Rio Negro County, Pico da Neblina, 2030 m a.s.l., 08–12.x.1990, Malaise trap, collectors J.A. Rafael & J. Vidal (female, INPA) . Paratype, as holotype, except 08–13.x.1990 (1 female, INPA) .

Diagnosis. Female, head dorsally dark brown from posterior margin to median ocellus, yellow from median ocellus to anterior margin of labrum ( Fig. 12A, B ); pronotum yellow ( Figs. 11A, B , 12B, C ); wings costal region yellow until near ¾ basal length, the remaining length and region brown ( Fig. 11 A–C).

Etymology. The specific epithet of the new species is in honor of Yoshiki Hayashi, a Japanese musician, songwriter and composer, leader of the X Japan rock band for his excellence in music and contribution to humanitarian causes around the world, including the preservation of Amazonian forest. The new species was collected in a region of a well-preserved Amazonian forest. Hopefully, the contributions of Yoshiki and others who follow his example, will continue to help preserve the Amazon, protecting the Amazonian habitat of the new species.

Description. Female ( Figs. 11–13 ): Total length: 23.3 mm, 19.6 mm (from head anterior region until forewing apex, n= 2). Forewing length: 17mm, 14.4 mm (n = 2). Head: Dorsally, parietal and frontal region, including ocellus area, dark brown, yellow from median ocellus until labrum anterior margin ( Fig. 12A, B ); ventrally, yellow with region behind the eyes dark brown, maxillary and labial palps dark brown ( Fig. 12C, D ). Antennae dark brown, with scape and pedicel yellow with some small brown spots; first 10 flagellomeres with yellow marks laterally ( Figs 11B , 12C, D ). Thorax: General color yellow; pronotum yellow, mesonotum brown anteriorly with some yellow region distally; meso and metathorax with some dark-brown regions laterally ( Fig. 11B, C ). All legs dark brown, except coxae yellow; femora basally with small yellowish area on external margin ( Fig. 11B, C ). Wings costal margin region yellow until near ¾ basal length, the remaining length and region brown ( Fig. 11 A–C). Abdomen: Yellow. Tergum IX wider than long, with a dense group of setae on distal margin ( Fig. 13A ). Sternum VIII ( Fig. 13B ) almost as long as wide; ratio between length (median region) and width (widest region) 0.9; approximately quadrilateral in shape; with a group of long dense setae on median region ( Fig. 13B ); posterior margin with u-shape median notch ( Fig. 13B, C ). Sclerotized band of sternum IX at the same height as posterior margin of sternum VIII ( Fig. 13B ); band thicker laterally, turning narrower medially ( Fig. 13C ). Cerci long, setose, segments 1–4, internally light colored, other segments brown.

Male and nymph: unknown.
