Janegoodallia gen. nov.

Type species: Janegoodallia davenporti sp. nov.

Diagnosis. Janegoodallia is defined as a new genus of the Metarbelidae based on the following putative morphological apomorphies (A–C):

A. The male genitalia of Janegoodallia has transtilla-like or band-like processes which belong either to the tegumen or they are attached to the base of the uncus. These unique structures comprise all together four band-like processes, that are without scales and setae, or two on each side above the valva, respectively. The two band-like processes are connected at base with each other and have an acuminate tip. One process is broad and large while the smaller one is three times narrower and only about half of the length of the larger one. The smaller band is strongly bent and looks like a scimitar.

B. Vein M1 is initiating at the base of the posterior vein of areole in the forewing. The areole is long and very narrow (= stick-like). A long and very narrow areole occurs also in species that belong either to the genus Metarbela Holland (1893) or to one undescribed genus (Lehmann in prep.), but in all species that belong to one of these two genera vein M1 is never initiating at the base of the posterior vein of areole but arising from one-third or about middle of discal vein and hence, from the posterior margin of discal cell.

C. The forewing and hindwing pattern is simple but unique among the Metarbelidae due to tiny transparent scales that occur on large parts of the wings and result in the transparent appearance, namely on the outer half of the forewing and near its base as well as on almost the whole surface of the hindwing. There is no other species among the Metarbelidae that has such a largely transparent forewing and hindwing due to tiny transparent scales without a colourful or violet glint, respectively.

Note: There are few other species among the Metarbelidae , and all belong to the genus Paralebedella Strand (1923) that have a transparent appearance of the forewing with orange-pink or light pink hindwings, sometimes a little bit transparent, but all transparent parts on both wings are more densely covered with much larger scales (if compared with Janegoodallia ) that have a strong violet glint. All species of the genus Paralebedella have a very different venation (e.g. without an areole) as well as male genitalia (e.g. with a large gnathos possessing various different processes) (cf. Lehmann 2008a Figures 1 g, 2g and Lehmann 2008b Figure 1 f).

Description of Janegoodallia gen. nov. Regarding all Metarbelidae , the single specimen representing this genus is of medium size (wingspan 25.0 mm). Head: Rough-scaled, without pits and without a pair of projections on lower fronto-clypeus; labial palpi short, three-segmented, and their length is less than the eye diameter; male antennae bipectinate, flagellum scaled dorsally; dorsal side of branches scaled; ventral side of branches with short sensory setae which are equal in length if compared with the branch width. Thorax: Densely covered with hair-like scales; with a short crest on metathorax; epiphysis very long (1.2 mm), narrow, bent and tube-like from base of foretibiae to almost half of first tarsomere. Hindlegs with two pairs of narrow tibial spurs (ca. 0.9 mm). Forewing largely transparent and without any complex pattern. Central part of the forewing with a simple pattern, represented by a broad pale olive band from costa to dorsum edged black along the transparent parts ( Figure 6 ). Wing venation ( Figure 7 ) similar to the genera Moyencharia Lehmann 2013 and Dianfosseya gen. nov. but with two major differences on the forewing (a–b):

a) Janegoodallia has a long areole, very narrowly rectangular-shaped (stick-like).

b) Vein M1 is initiating from base of the posterior vein of areole.

On the forewing, vein 1A+2A is forked at base, CuP absent, CuA2 originating from hind margin of posterior part of cell, CuA1, M3 and M2 basally separated, initiating from posterior angle of posterior part of cell, M1 initiating from base of posterior vein of areole, R1 initiating from anterior margin of anterior part of cell, R2 initiating from anterior angle of areole, R3+R4 are long stalked and initiate from the posterior angle of areole, R5 initiates from the posterior angle of areole and is slightly separated at base from R3+R4, Sc more or less parallel to R1. In hindwing 3A and CuP present (like in Dianfosseya ), 1A+2A obsolete (represented by a short fold), CuA2 initiating from hind margin of posterior part of cell, CuA1, M3 and M2 basally separated, initiating from posterior angle of posterior part of cell, M1 and Rs initiating from a very long stalk of the anterior angle of anterior part of cell with a bar from Rs to Sc+R1 (like in Dianfosseya ); discal cell of both forewing and hindwing with a vein (stem of vein M); ciliae very short. Retinaculum and frenulum absent. Abdomen: With dense hair-like scales and long abdominal tuft (ca. 30% of the length of the abdomen).

Male genitalia. Saccus long, broadly elongated and rounded; uncus very large and triangular-shaped, bifurcated at the tiny tip, with two oval-shaped holes below. Valva broadly squarish with an arc-shaped costal margin and with an extending tip of the sacculus distal-ventrally (ventral view). A small, thinly membranous skinlike appendage is covered with some setae and occurs distal-dorsally, extending slightly towards the tegumen and above the coastal margin; long setae occur along the edge of uncus. Transtilla-like processes present. Juxta large and wide. Phallus simple and slightly longer than genitalia length (in a lateral view), vesica without cornuti ( Figure 8 ).

Female unknown.

Distribution. Janegoodallia is found near Isiro (north-eastern DRC).

Ecology. See under Dianfosseya gen. nov.

Etymology. Janegoodallia is named after the primatologist and conservationist Jane Goodall (born on the 3rd of April, 1934, in London) to honour her long-term and fundamental field studies on the behavior of wild chimpanzees in Gombe Stream National Park ( Tanzania), beginning in 1960, and for educating the public about the endangered habitats of chimpanzees in various African nations as well as the unethical treatment of chimpanzees by humans, although they are their closest relatives. The gender of the new genus is feminine.
