Systellapha ornatifemur new species

Figs. 2 C–D, 3 A–E

Description: Head: Mostly pale brown to yellow, frontal vitta yellow-orange and silvery microtrichose except for a velvety black circular swelling occupying the lower half of the pre-ocellar part of the vitta and an elongate bare patch surrounding a black ocellar tubercle. Orbital strip dull yellow-orange. Parafacial yellow-orange except for a small black patch along boundary with lower margin of orbital strip. Pedicel with black apical ventral bristles.

Thorax: Mesonotum with a broad central strip flanked by silvery microtrichose margins, broad central strip uniformly brown, without a narrow central vitta. Posterior row of katepisternal bristles black, other katepisternal bristles yellow. Dorsocentral bristles in two postsutural pairs. All tarsi white. Mid and hind femora pale yellow with long, distinct and broad brown bands on basal halves, brown bands of distal halves similar in length to preceding pale area.

Female abdomen: Pleuron uniformly pale. Tergites pale brown, T1, anterior margin of T2 and anterolateral portions of T3 silvery microtrichose. Oviscape shiny dark brown except for pale apex. Spermathecae with major duct very long, inconspicuously striate and almost parallel sided; stems of spermathecae slightly swollen and bent at middle, spermathecae club-shaped with base of club bent and tapered to junction with stem and with a cluster of tubercles at junction with stem. Minor duct similar but smaller and about 1/3 as long, leading to paired small spermathecae on short, unmodified stems. Ventral receptacle very small, simple.

Male abdomen: Pale brown, microtrichose, dull except for shiny S8. Pleuron pale except for dark pleural membranes P1 and P2; P2 with a very dark pleural sac on dorsal half. Sternite 5 with an elongate genital fork, with long, slender arms distinctively turned in and slightly downturned in distal half, base of each arm with a strong quadrate lobe ending in 4–5 spurs, two more distal finger-like inner processes each ending in a single spur, and about 6 more distal spurs. Basal distiphallus broad and depressed, as long as epandrium; genital bulb small and globular; distal distiphallus long and slender, slightly tapered towards apex.

Type material: Holotype (#m, DZUP): BRAZIL. Paraná, São João de Graciosa, Poço Preto , 25°23’54”S, 48°52’6”W, 76m, multilure traps, 24-28.Feb.2015, M. Savaris & A. L. Norrbom, DEBU collection number 00398225 (barcode sequence number MYCRO0593-19 ).

Paratypes: BRAZIL. Same data as holotype, DEBU collection numbers 00398222, 00398223, 00398224 (1#m USNM, 1#m,1#f, DZUP); Rio de Janeiro, Tijuca, 29-8-39, Freitas E. Lopes (1#m, INPA, labelled Grallipeza ornatithorax det. L. Albequerque) .

Etymology: The specific name refers to the boldly banded mid and hind femora, which differ from the weakly marked femora of S. ornatithorax .
