Tribe Laberiini trib. nov.

urn:lsid:zoobank.org:act:F8F8C80E-EA21-4759-AF47-C4BB195F1082

Type genus

Laberia Stål, 1866 ; here designated.

Diagnosis

Head capsule narrower than thorax, projecting in front of eyes. Pedicel with plate organs on the whole surface reaching to its base. Rostrum long, ending between metacoxae. Tegmina broad, extending far beyond abdomen, held flattening tectiform, with their ventral faces not facing each other; costal area present and wide, with reticulate venation; nodal line not materialized. Hind tibia with 5–7 lateral spines. Metatarsal apical teeth asymmetrical. Male gonostyli symmetrical, not fused. Female: gonoplacs flat quadrangular, wide, without apical marginal teeth. Gonapophyses IX with a long, lateral, digitated process. Anal tube short, ring-shaped.

Content

Monotaxic tribe currently with one genus – Laberia Stål, 1866 .

A new simplified key to higher taxa of Elicinae to accommodate the new tribe Laberiini trib. nov. is proposed here:

1. Tegmina usually with distinct nodal line and venation distinctly reticulate distally; gonoplacs elongated, usually with marginal teeth; gonapophyses IX in shape of isosceles triangle .................. .................................................................................................................. Tropiduchinae Stål, 1866

– Nodal line of tegmina not distinct; gonoplacs rounded without marginal teeth; gonapophyses IX not triangular ............................................................................................... Elicinae Melichar, 1915 ... 2

2. Tegmina short, reticulate, with transverse costal veins; ScP+R and MP with common stem ............ .................................................................................................... Patollini Szwedo & Stroinski, 2013

– Tegmina short or surpassing abdomen; ScP+R and MP leaving basal cell separately ..................... 3

3. Tegmina steeply tectiform, surpassing abdomen; in dorsal view lateral margins of gonapophyses IX straight .............................................................................................................................................. 4

– Tegmina flatly tectiform; in dorsal view lateral margins of gonaphysis distinctly protruded with tooth or long digitate process ..................................................................................................................... 5

4. Tegmina not reticulated; metatibia with one spine; metatarsal apical teeth asymmetrical ................. ..................................................................................... Bucini Gnezdilov, Bartlett & Bourgoin, 2016

– Tegmina reticulated; metatibia without spines; metatarsal apical teeth regular ................................. ............................................................................................................ Parathisciini Gnezdilov, 2013

5. In dorsal view lateral margin of gonapophysis protruded with a short tooth-like process ................. ......................................................................................................................... Elicini Melichar, 1915

– In dorsal view lateral margin of gonapophysis bearing a long digitate process ................................. .............................................................................................................................. Laberiini trib. nov.
