Diagnosis

G. emeljanovi can be distinguished from other species of the genus by the unique shapes of the style, connective, and aedeagus. G. punctifer (Walker, 1858) is also recorded from Madagascar, and the new

species can be distinguished from it by the shorter pygofer, absence of a pygofer process, and absence of paired apical or medial processes of the aedeagus.

Etymology

This species is named in honor of Dr. A.F. Emeljanov, who has made extensive contributions to the knowledge of the Deltocephalinae .

Description

SIZE. ♂ 5.2 mm, ♀ 5.5 mm.

COLOR. Generally brownish, mottled with darker brown and ivory markings.

BODY. Head slightly wider than pronotum. Crown broad; slightly longer medially than next to eye; glabrous with longitudinal striations; convex; rounded to face. Ocelli on anterior margin of head; 3 x their own diameter from adjacent eye. Frontoclypeus tawny, speckled with dark brown and red dots; slightly longer than wide. Clypellus widening apically. Lorum wider than clypellus at base. Gena with fine erect seta distant from laterofrontal suture. Antennal sockets near lower corners of eyes. Antennal ledges weakly carinate. Antennae short. Pronotum carinate laterally; lateral margin slightly less than 0.5 x width of eye. Forewing with extensive brown irrorate markings; veins whitish, interrupted by brown markings; with crossvein between A1 and claval suture; with A1-A2 crossvein. Protrochanter with stout apical seta. Profemur row AV setae relatively long. Protibia dorsal surface rounded; macrosetae 3+4. Mesotrochanter with stout apical PV and AV setae. Mesofemur row AV with ~7-8 relatively long setae. Mesotibia dorsal setae 4+4. Metatibia pecten setae nearly equal in size. Metatarsomere I pecten with 5 platellae; PV seta platellate.

MALE. Pygofer short; rounded; incised dorsally to midlength; with ~8 long macrosetae near posterior margin; with numerous shorter thick setae posteroventrally; pygofer lobes nearly touching ventrally. Subgenital plates fused; with numerous macrosetae subapically. Connective short; Y -shaped; fused to aedeagus. Style very broad basally; median anterior arm long, extended dorsally to meet connective; preapical lobe knob-like; apophysis with setae basally; apex expanded, with two points; apex textured with several rows of small bumps.Aedeagus very broad at base in ventral view; excavated ventromedially; bifurcate at apex; dorsal margin dentate apically.

FEMALE. Sternite VII undulately excavated. Pygofer with medium-sized macrosetae ventrally and subapically. First valvulae slender; strongly convex; dorsal sculpturing pattern strigate basally, concatenate apically, reaching dorsal margin. Second valvulae slender; with short irregular dorsal teeth and serrations on apical 1/3. Third valvulae with ventroapical row of ~6 distinct setae.
