Material examined. -

HT Lamellitettigodes karwinkeli : ♀, China, S-Yunnan, Xishuangbanna, 23 km NW Jinghong, vic. NA Ban Village (NNNR), 22°10'N, 100°39'E, 700-1000 m, V.-VII.2009 (diverse traps), leg. L. Meng, NMNG.

Diagnosis. -

L. karwinkeli , together with L. sagittatus and L. signatus species, has pulvilli with apical teeth. Together with L. sagittatus it is a species with long and slender antennae (more than 2 times longer than fore femur. It differs from L. sagittatus by the higher pronotum with a broad depression between the shoulders and morphology of fastigium; in frontal view the ventral margin of transverse carina form a right angle with the lateral carina in L. karwinkeli , while it is rounded in L. sagittatus .

Description. -

Body long and slender. Head and pronotum smooth. Head and eye in lateral view clearly elevated above pronotal discus. Dorsal margin of antennal groove between eyes, slightly above ventral margin of eye. Eyes small and in lateral view blunt and indistinctly conoidal. Antenna (4.5 mm) filiform with long and slender segments, 15-segmented in female (including scapus and pedicel), 2.4 times longer than fore femur. Fastigium of vertex in dorsal view smaller than width of one eye. Fastigium in frontal view between the eyes depressed. Ventral margin of transverse carina forming with lateral carina square (right angle). Fastigium in dorsal view with well-developed medial and lateral carinae and fossulae. Lateral carina clearly elevated, but in lateral view as high as the dorsal margin of eye, short and not converging towards front, bending over at right angles to the medial carina. Transverse carina in dorsal view slightly convex. Frontal costa and facial carina in lateral view clearly visible in front of eye. Tip of fastigium and frontal costa in lateral view distinctly protuberant. Bifurcation of frontal costa into facial carinae close to transverse carina. Facial carinae in lateral view clearly concave in front of eye and slightly convex in front of antenna. Last segments of maxillary palp not widened. Anterior margin of pronotum truncated. Pronotum expanded between shoulders. Clearly keeled prozonal carinae slightly converging backwards. Median carina from the anterior margin of the pronotum to the level of the end of tegmen distinctly keeled, with two flattened elevations before and behind shoulders. Interhumeral carinae absent. Internal lateral carinae weak. Pronotum behind shoulders weakly depressed on both sides of median carina with black spots (posthumeral spots) forming broad black band. Lateral lobes broadly rounded, more or less close to body. Tegmen slightly shorter than fore femora, slender, at the end broadly rounded. Macropterous and macropronotal. Alae clearly exceed the pronotum apex. Fore and middle femora slender, with slightly undulated margins. Hind femora with very small antegenicular and especially genicular teeth, with some sharply tuberculate raised lobes on the middle outer surface. Posterior tibia distally not or weakly widened, with a few small spines on upper edges. First segment of the hind tarsus not longer than the third segment of tarsus. Pulvilli distinctly acute with apical teeth.

Measurements. -

(in mm) HT: Pronotum length 15.05; pronotum lobe width 3.50; pronotum height 2.15; vertex width 0.47; eye width 0.56; tegmen length 1.65; hind wing length 12.61; postfemur length 6.11; postfemur width 1.43.

Pictures of HT are available in higher resolution in OSF ( Cigliano et al. 2019).

Distribution. -

The species is only known from the type locality near Xishuangbanna (Yunnan, PR China).

Note: I cannot find any other species of Lamellitettigodes from PR China. There are likely to be further species from PR China that should be assigned to Lamellitettigodes , but since there are only drawings and only a few photographs, such work remains for future revisions.

Etymology. -

This species is dedicated to Fabian Karwinkel, a great ornithologist and a committed young conservationist from Northrhine-Westphalia. The specific epitheton is second (US) declension Genitive case of the Fabian’s Latinized version of the surname ( Karwinkelus = karwinkeli ).
