Hyantia bahlenhorsti n. sp.

( Fig. 1 ; Table 1 )

TYPE MATERIAL. — Holotype: “FR GUIANA / Kaw Rd PK-37 / 17-VIII-1996 / J E Wappes”, 1 ♂ ( UGCA).

Paratypes: “FR GUIANA / Kaw Rd PK-39 / 18-VIII- 1996 / JE Wappes”, 1 ♂ ( UGCA), 1 ♂ ( AFSC). — “ FRENCH GUIANA: 41 / km SE Roura on Kaw Rd / 5-7-VI-2005, J. E. Eger / & M. T. Messenger, coll. // N04°32.214’ / W052°07.420’ / 272 m MV Light”, 1 ♀ ( FSCA), 1 ♀ ( AFSC).

ETYMOLOGY. — The species is named in honor of Mark Bahlenhorst, a dear friend who passed unexpectedly and often assisted the author with fieldwork on cicadas.

DISTRIBUTION. — The species is only known from French Guiana.

DIAGNOSIS. — The species is similar in general appearance to Hyantia honesta ( Walker, 1850) . The new species is smaller (body length 33.8 mm vs 44 mm), the head is truncated anteriorly in H. bahlenhorsti n. sp. but rounded in H. honesta , male opercula are angled posteriolaterally in H. bahlenhorsti n. sp. but smoothly rounded in H. honesta , the basal membranes of the wings are green (or faded to ochraceous) in H. bahlenhorsti n. sp. but orange-reddish in H. honesta , and the ventral lobes of the uncus curve downward in H. bahlenshorsti n. sp. but are straight in H. honesta .

DESCRIPTION

Ground color bright green fading to ochraceous with age.

Head slightly wider than mesonotum without markings. Covered with golden pile dorsally, longer posterior to eye. Ocelli golden, green or marked with red. Eyes golden. Ventral head ground color. Postclypeus centrally sulcate, with eleven transverse grooves. Short whilte pile on lateral postclypeus. Long white pile on lorum, posterior half of gena, and lateral half of anteclypeus. Rostrum with piceous tip reaching to posterior coxae. Scape and proximal pedicel ground color, distal pedicel and antennal flagella piceous.

Dorsal thorax ground color. Parapsidal suture testaceous in some paratypes. Sparse, short golden pile in sutures of prothorax. Long, dense golden pile on posterior mesonotum, in wing groove, and on posterior metanotum.Less dense golden pile between anterior arms of cruciform elevation and on lateral mesonotum. Ventral thoracic segments dusted with white pruinosity. Ground color except testaceous episternum 2 and trochantin 2. Katepisternum 2 and meron 2 testaceous in some paratypes. Segments with fine white pile, longer on lateral anepisternum 2 and posterior katepimeron 2.

Tegmina and wings hyaline, tinged with blue when viewed at an angle. Venation ground color. Basal cell and proximal clavus, and basal membrane of tegmina and proximal portion of wing basal cell, medial cell, cubital cell 1, cubital cell 2, anal cell 1, and anal cell 2 greenish. Anal cell 3 and anal cell 2 along anal veins 2 and 3 grayish-green.

Legs ground color. Fore femora with proximal spine oblique, secondary spine upright and small tertiary spine. Small testaceous mark on anterior distal coxae and proximal trochanters. Distal femora and tibiae marked with darker green. Tarsi dark green, pretarsal claws with piceous tips.Tibial spurs and comb testaceous with piceous tips. Dark green fades to testaceous.

Male operculum with smoothly rounded posterolateral margin to auditory capsule, posterior margin straight to curved medial margin, reaching to middle of sternite II. Medial margin extending to middle of hind coxa. Meracanthus ground color, short. Female operculum with rounded posterior margin, terminating medially at short meracanthus reaching to middle of sternite II. Opercula covered with white pile and white pubescence.

Abdomen ground color covered with fine golden pile. Sternites and epipleurites dusted with white pruinosity, more dense along segment margins. Timbal cover incomplete exposing timbal dorsally, ventral margin straight, anterior margin semicircular ventrally then straight as it tapers to junction of posterior tergite 2.

Male pygofer with distal shoulder pointed dusted with white pubescence laterally. Dorsal beak folded to anal styles. Pygofer upper lobe roughly triangular. Median uncus lobes recurving dorsally and expanding distally. Distal median uncus lobe slightly bifurcating and curving to straight posterior margin before continuing to lateral uncus lobes forming a U-shaped margin. Lateral uncus lobes curve ventrally at distal terminus. Long golden pile on proximal median uncus lobes and lateral portion of lateral uncus lobes. Aedeagus testaceous striped with piceous.

Female genitalia ground color except piceous gonapophysis VII. Sternite VII with a double notch and dark green patches laterally. Dorsal beak extending just beyond anal styles.Posterior margin of abdominal segment 9 sinuate, dense dark testaceous spines on either side of ovipositor on posterior ventral margin. Long golden pile in medial margin of abdominal segment 9 and on ovipositor sheath, short golden pile on surface of abdominal segment 9. Ovipositor sheath extends just beyond dorsal beak.

Measurements: see Table 1 .
