Popov, Yuri A. & Heiss, Ernst, 2016, A remarkable fossil leptosaldine bug from Mid-Cretaceous Burmese amber (Hemiptera: Heteroptera: Leptopodomorpha: Leptopodidae), Zootaxa 4137 (2), pp. 233-238 : 237

Leptosaldinea cobbeni sp.nov.

( Figs. 1–12 )

Type material. Holotype: macropterous female preserved in a piece of Burmese amber which is embedded in a block of transparent artificial resin for better conservation, provided with following red label: “ Holotype / Leptosaldinea gen.nov. / cobbeni sp. nov. / des. Heiss & Popov, 2015”. The holotype is deposited in the collection of the second author (EH) at the Tiroler Landesmuseum, Innsbruck, Austria.

Body convex; left eye and pronotal margin damaged, surface of median part of pronotum, scutellum and clavus missing and probably eaten by scavengers, their remains depressed and not clearly discernible; legs and antennae complete with long spines and setae.

Description. As given in the generic diagnosis and description.

Measurements (mm). Length 2.75; width of hemelytra 1.35; length of antennae 1.95, ratio length of antennae / width of head = 2.78; length of antennal segments I:II:III:IV =0.15:0.25:0.75:0.80; length of rostral segments I:II:III:IV =?:0.15:0.20:0.20; length of pronotum at middle 0.4, anterior width 0.5, posterior width 0.85; scutellum length 0.37; legs: femur:tibia:tarsus including claws: fore leg 0.875:0.8:0.4; middle leg 0.875:0.875:0.375; hind leg 1.0:1.40:0.5. Drawings might show slight differences to given measurements because of partly obscured visibility of structures.

Etymology. Named after the eminent Dutch hemipterologist René Cobben, who proposed the subfamily Leptosaldinae for the first discovered leptosaldine species, Leptosalda chiapensis .
