The genus Lamellitettigodes Günther, 1939 from Southeast Asia is reviewed. The genus currently includes seven species and is transferred to Tetriginae Rambur, 1838. Two new species are described: Lamellitettigodes novaeguineae sp. nov. from New Guinea and Lamellitettigodes karwinkeli sp. nov. from Yunnan, People’s Republic of China. Lamellitettigodes palawanicus Günther, 1939 stat. nov. is no longer regarded as a subspecies of L. contractus, but a separate species. Two species are transferred from Euparatettix Hancock, 1904 to Lamellitettigodes: Lamellitettigodes sagittatus (Bolívar, 1887) comb. nov. and Lamellitettigodes cultratus (Bolívar, 1898) comb. nov. One species is transferred from Tetrix Latreille, 1802 to Lamellitettigodes - Lamellitettigodes signatus (Bolívar, 1887) comb. nov. Xistra tricristata sumatrana Bolívar, 1898 syn. nov., Xistra tricristata Bolívar, 1898 syn. nov., and Probolotettix corticolus Blackith & Blackith, 1987 syn. nov. are synonymized with Lamellitettigodes contractus (Bolívar, 1887). Probolotettix kevani Blackith & Blackith, 1987 syn. nov. is synonymized with Euparatettix personatus (Bolívar, 1887). Additionally, in the genus Lamellitettix Hancock, 1904, Lamellitettix acutus Hancock, 1904 stat. rev. is retransferred from a subspecies of Lamellitettix gallinaceus (Stål, 1877) to a separate species status.

Various cameras using various lenses were used to take photos, all in macro mode by using a stacking system with an integrated scale bar or with a macro lens and millimeter paper. No post-processing of photographs was done. Millimeter paper was placed close to the photographed specimen and subsequently used to construct a scale bar, included in the photograph, after which the millimeter paper was deleted.

Lamellitettigodes
Günther, 1939: 123;
Paratettix contractus (Bolívar, 1887), by original designation.
In contrast to Metrodorinae, in Lamellitettigodes the antenna is inserted at the lower margin of the eyes, and the first segment of the hind tarsus is longer than the third segment. The similarity of Lamellitettigodes species with Paratettix and Euparatettix is clear when comparing all morphological characters from most of the Paratettix and Euparatettix species of Southeast Asia. Lamellitettigodes species have typical characters of Tetriginae: rounded lateral lobes of pronotum close to pronotum (directed downwards, slightly sidewards; this character is somewhat similar to Metrodorinae), presence of posthumeral spots on the pronotum, L-shaped carinae of the vertex, pulvilli of the hind tarsus with apical teeth (absent in some Lamellitettigodes species), and hind wings exceeding the tip of the pronotum. Therefore, Lamellitettigodes is very close to Tetriginae and did not belong to Metrodorinae: I transfer this genus to the subfamily of Tetriginae.
Body of moderate size, slender. Head and pronotum smooth. Head and eye in lateral view not at all or slightly elevated above the pronotal discus. Antenna more than 1.5 times longer than fore femur, dorsal margin of antennal groove a little bit above the ventral margin of eye, between the eyes. Eyes small and in lateral view blunt and indistinctly conoidal. Antenna filiform, 14-segmented in male (including scapus and pedicel), 15-segmented in female. Fastigium of vertex in dorsal view as broad as or a little wider than the eye, fastigium in frontal view between the eyes slightly depressed. Fastigium in dorsal view with well-developed medial, lateral carinae, and fossula. Lateral carina clearly elevated, in lateral view weakly visible above the eyes and short, in dorsal view not converging towards the front, almost parallel, bending over at right angles to the medial carina (L-shaped). Transverse carina of the vertex in dorsal view slightly convex or straight. Frontal costa and facial carina in lateral view visible in front of eye (except in L. novaeguineae). Tip of fastigium and its frontal costa in lateral view protuberant. Facial carinae in lateral view concave in front of eye and slightly convex in front of antenna. Last segments of maxillary palps not foliaceous. Anterior margin of pronotum truncated. Pronotum slightly between shoulders. Prozonal carina and median carina clear, slightly elevated (lamellate in L. cultratus and L. novaeguineae), interhumeral carina absent, internal lateral carinae not clearly visible. Pronotum behind shoulders weakly depressed on both sides of median carina and here very often provided with black spots (posthumeral spots) on each side. Lateral lobes broadly rounded, not as close to body as in Paratettix. Tegmen almost as long as the fore femur, rather broad and at the end broadly rounded. Macropterous and macropronotal. Alae clearly exceed the pronotum apex. Hind femora with very small antegenicular and especially genicular teeth, with some sharply tuberculate raised slants of their middle outer surface. Posterior tibia distally not or slightly widened, with a few small spines on upper edges. First segment of the hind tarsus not longer than the third, pulvilli acute, in three species with apical teeth (L. sagittatus, L. signatus, L. karwinkeli). The coloration is highly variable and not a useful feature for either generic or specific diagnosis (as reported for Tetriginae in
The genus Lamellitettigodes is characterized by a protuberant tip of fastigium and frontal costa (in lateral view); facial carinae in lateral view visible and clearly concave in front of eye and slightly convex in front of antenna. Only in L. novaeguineae is tip of pronotum not visible in lateral view, but present. Additional characters for the genus are: 1) lateral carina of the vertex in frontal view clearly elevated as small fastigial horns, but in lateral view weakly visible above the eyes (Plate
The genus is close to Euparatettix and Paratettix (see above). In the typical representatives of mentioned genera, the tip of the fastigium is not protruding, but more or less rounded. Also, frontal horns are absent. In Paratettix the median carina is absent in the frontal margin of pronotum. A similarity exists also with Lamellitettix Hancock, 1904. The type species of the genus is Lamellitettix acutus Hancock, 1904 stat. nov.
Altogether seven species are now assigned to the genus Lamellitettigodes: one hitherto described species (widely distributed L. contractus from peninsular Malaysia, Singapore, Sumatra, Java, Borneo, Sulawesi, and Solomon Isl.) supplemented with a subspecies (L. c. palawanicus inhabiting Palawan archipelago of the Philippines) here elevated to the species level, two new combinations (widely distributed L. sagittatus from Vietnam, Thailand, peninsular Malaysia, Sumatra, Java, Borneo, Philippines, Moluccas Isl., Sulawesi, New Guinea, and Timor, and L. signatus from the Philippines) and two species described here as new to science (L. novaeguineae inhabiting SE New Guinea, and L. karwinkeli inhabiting Yunnan, PR China). One hitherto described species (L. sumatrana) and a subspecies (L. contractus tricristatus) are synonymized with L. contractus.

L. contractus has more or less parallel prozonal carinae, slightly bent backwards. The distance between the upper margin of the superior ocelli and frontal margin of the fastigium is significantly larger than a diameter of an ocellus in frontal view. The species is similar to L. palawanicus. This species can be easily separated by the tip of fastigium and frontal costa, which are distinctly protuberant in front of the eyes, and the fastigial horns, which are clearly visible above the eyes.

L. sagittatus has, together with L. signatus and L. karwinkeli, pulvilli of the hind tarsi bearing apical teeth. Bifurcation of the frontal costa into facial carinae is close to the transverse carinae of the vertex. In L. signatus, the median carina is bent to the tip of the pronotum while in L. sagittatus and L. karwinkeli the median carina rises again in the prozona. In contrast to L. karwinkeli, the median carina of L. sagittatus is flat or weakly wavy. In frontal view, there is a right angle between lateral and transverse carina in L. karwinkeli, while in L. sagittatus the angle is rounded.
Specimens of L. sagittatus have variable size and coloration. Specimens from New Guinea have in frontal view less flattened fastigium than specimens from other regions. However, they belong to L. sagittatus because all other characteristics are the same.

L. palawanicus has almost parallel prozonal carinae that are slightly bent backwards. The distance between upper margin of superior ocelli and frontal margin of the fastigium, in frontal view, is significantly larger than the diameter of ocellus. The species is similar to L. contractus. L. palawanicus can be separated from the similar species by the tip of fastigium and frontal costa that are distinctly protuberant in front of the eyes and by fastigial horns that are clearly visible above the eyes.

The species is easily recognizable by the raised median carina with broad depression between the shoulders. This depression clearly distinguishes it from L. cultratus. It is also slightly raised in Chinese L. karwinkeli but does not reach the same height and is not lamellated. As a further feature, the fastigium tip is only slightly visible in front of the eyes.
Body of moderate size and slender. Head and pronotum smooth. Head and eye in lateral view weakly elevated above the pronotal discus. Dorsal margin of antennal groove slightly above the ventral margin of eye. Eyes small and in lateral view blunt and indistinctly conoidal. Antenna filiform, 14-segmented in male (including scapus and pedicel), while 15-segmented in female, 1.5–2.0 times longer than fore femur. Fastigium of vertex in dorsal view slightly wider than one eye. Fastigium in frontal view between the eyes slightly depressed. 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 eyes, short, not converging towards the front, bending over at nearly right angles to the medial carina. Transverse carina in dorsal view straight. Frontal costa and facial carina in lateral view minimally visible in front of eye. Tip of fastigium and frontal costa in lateral view slightly, but still clearly, protuberant. Bifurcation of frontal costa into facial carinae between dorsal margin of lateral ocelli and transverse carina, close to transverse carina by less than one diameter of ocellus. 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 the pronotum truncated. Pronotum slightly widened between shoulders. Clearly keeled prozonal carinae converging backwards. Median carina distinctly lamellate from anterior margin of the pronotum to the end of tegmen, with a broad depression between shoulders. Interhumeral carinae absent. Internal lateral carinae weak. Pronotum behind shoulders weakly depressed on both sides of median carina, with large black spots like a broad black band (posthumeral). Lateral lobes broadly rounded, more or less close to body. Tegmen almost as long as the fore femur, rather broad, at the end broadly rounded. Macropterous and macropronotal. Alae clearly exceed the pronotum apex. Fore and middle femora short and widened, with wavy margins. Hind femora with very small antegenicular and especially genicular teeth and with some sharply tuberculated 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 third segment. Pulvilli acute.

The species is only known from lowlands in the South of New Guinea (surroundings of Fly River and Lakekamu River).
The species is named after the island of New Guinea (Nova Guinea) where it is an endemic species of the genus Lamellitettigodes. The specific epitheton is made of two words, adjective and noun of the first (A) Latin declension, both in Genitive case (Novae Guineae = novaeguineae).
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.
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.
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.
(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.

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.
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).

HT Probolotettix kevani: ♂, Indonesia, Sulawesi Tengah, Ramu Camp, Kolonodale area, 5.II.1980, leg. P. G. Kevan,
PTs Probolotettix kevani: ♂, Indonesia, Sulawesi, Minehassa Prov., Dumoga-Bone National Park, I.–III.1985, leg. R. & R. Blackith,
The HT is a typical E. personatus (elevated head, short prozona, hind tibia with a bright light ring). Therefore, I synonymize Probolotettix kevani with E. personatus. The description and the drawing of the PT in

My special thanks go to all institutions for graciously lending me specimens from their collections and for the patience they have shown for my research. I especially thank the Zoologische Forschungsmuseum Alexander Koenig in Bonn and their staff for their support and assistance. I am also thankful to Ingrid Bunker for proof reading and Josip Skejo for their intensive revision.
