Differential diagnosis

Ramya longiprocessus gen. et sp. nov. is externally most similar to its sister species R. megatrium gen. et sp. nov.; however, R. longiprocessus has pronounced, dark markings on the crown, thoracic dorsum, mesonotum, scutellum and the inner ante-apical cell with accessory cross veins. Additionally, the male pygofer ventral process is straight, aedeagus with lateral and dorsal flanges, atrium not enlarged, about half as long as the shaft in lateral view, segment X long, tubular, lateral and dorsal anterior band sclerotized, while in R. megatrium the male pygofer ventral process is curved dorsally and recurved ventrally, the aedeagal shaft lateral and the dorsal flanges absent, the atrium greatly enlarged, about as long as the shaft in lateral view, segment X short and sclerotized.

Etymology

The specific name ‘ longiprocessus ’, a compound from the Latin ‘ longi ’ (long) and ‘ processus ’ (process), which refers to the elongated pygofer process. It is a noun in apposition.

Description

HEAD AND THORAX. Small-sized (3.67–3.86 mm) leafhoppers. Crown flat, 1.7× as wide as long. Pronotum 2.0 × as wide as long medially ( Fig. 1A–C View Fig ). Crown, thoracic dorsum, mesonotum, and scutellum with darker markings, crown with one short outwardly curved stripe on either side of the median line continues. Forewing outer ante-apical and inner ante-apical cells with accessory cross veins. Profemur row AV with 15 short, stout peg-like setae, intercalary row (IC) with 12 hair-like setae ( Fig. 3A–D View Fig ).

MEASUREMENTS. Male 3.67–3.86 mm long, 1.05 mm wide across eyes, 1.01 mm wide across lateral margins of pronotum and 0.81 mm wide across posterolateral angles of pronotum. Female 4.25 mm long, 1.14 mm wide across eyes, 1.10 mm wide across lateral margins of pronotum and 0.84 mm wide across posterolateral angles of pronotum.

MALE GENITALIA. Pygofer 1.3 × as long as wide, with straight, elongated blade-like ventral process, directed dorso-posteriorly surpassing pygofer ( Fig. 1E–F View Fig ). Subgenital plate 2.5× as long as wide, outer margin concave, apex long, thin, membranous ( Fig. 1G View Fig ). Style 2 × as long as wide, apophysis with rounded apex ( Fig. 1I–J View Fig ). Connective stem 2.5× as long as arms ( Fig. 1H View Fig ). Aedeagal shaft moderately long, curved dorsally, with pair of lateral flanges arising from base to pre-apical region and unpaired dorsal flange from base to apex ( Fig. 1K, M View Fig ); pre-atrium reduced, atrium well developed, not enlarged ( Fig. 1M View Fig ), about ½ × as long as shaft in lateral view. Segment X long, tubular, lateral and dorsal anterior band sclerotized.

FEMALE GENITALIA. Sternite VII broader than long, posterior margin weakly convex with narrow V-shaped notch medially ( Fig. 2E View Fig ). First valvula curved dorsally with sculptured area confined to posterior onethird, sculpturing pattern concatenate to strigate, reaching dorsal margin ( Fig. 2F–G View Fig ). Second valvula slightly curved dorsally, with hyaline area before denticular area, teeth prominent, triangular and distinctly separated, confined to posterior half ( Fig. 2H–I View Fig ).
