Holotype
♂ Gabon, Makokou, Ipassa research station (Ivindo National Park), 0°30’43”N 12°48’13”E, Feb.-Mar. 2011, A. Susini leg. In MSNS.
Diagnosis
Species similar to H. capeneri and H. nodosum in lateral view, easily distinguishable thanks to the absence of the caudal spine of the posterior process. In addition, H. capeneri has a shorter and thinner posterior process, and H. nodosum presents a clearly larger terminal node of the posterior process in lateral view.
Size
Total length: 3.4 mm Pronotal length: 2.8 mm Tegminal length: 3.5 mm
Description
HEAD: black, slightly convex, punctate, with quite dense golden pubescence; vertex 1.63 wider than high; a shallow concavity between the ocelli; upper margin arcuate, slightly sinuate; ventral margin W-shaped with the lower parts non very pronounced; ocelli clearly above the centro-ocular line.
Frontoclypeus oval, lateral lobes completely fused to frontoclypeus with margins hardly distinguishable; rostrum brown with black base; antennae brown.
PRONOTUM: black punctate, with many small yellow bristles and several thorn-like tubercles, each associated with a single apical seta; metopidium two times wider than high, median carina percurrent; supraocular callosities large, vaguely pentagonal, partially bare, unpunctated; humeral angles prominent and blunt; posterior angle rounded; suprahumeral horns reducerd, tuberculate, projected outwards, with a brown thorn at the top. Posterior process black, strongly produced emerging slightly dorsal to posterior margin and with apex extending little beyond the anal angle of forewing; sinuate in lateral view; with two nodes well observable in dorsal view at the anterior and posterior extremities; no spine at the caudal end; dorsal and ventral carinae percurrent; lateral carinae present only on the area between the nodes. The whole posterior process with few thorn-like tubercles gathered mainly along the carinae and on the nodes. All the tubercles with a small yellow bristle at the apex.
SCUTELLUM: entirely black, punctate, with the base longer than the height, emarginated with scutellar apices acute; base swollen except for the corners, with one ogival tubercle on each side of the swelling. The said tubercles with a tuft of small whitish backwards setae.
FOREWING: approximately two and half times longer than wide, hyaline, sclerotized basally, punctate, black in colour. Pterostigma sub-triangular, amber in colour, finely edged in black; venation lighter than pterostigma, but end of veins A1 and A2 and anal margin deep brown; a brown rectangularish dot at the anal angle.
LEGS: black with distal half tibiae and tarsi yellow; praetarsi black.
ABDOMEN: gray-brown with punctuation, dorsally covered by sparse whitish setae.
Etimology
The species is dedicated to Piero Carlino, MSNS, Lecce, Italy, for his valuable help in collecting Membracidae specimens.
The surname is latinized into Carlinus, of which the genitive is Carlini (ICZN art. 31.1.1).
