Figures 4 A–D

Lophotettix hancocki ( Bruner, 1910) ; pg. 102 [general description of Gladiotettix hancocki ], male holotype (ANSP); type locality: “ Brazil, Pará ”. Hancock, 1914 [ Gladiotettix hancocki is synonymous to Lophotettix unicristatus ]. Günther, 1938 [ Lophotettix hancocki potential synonym of L. unicristatus ]. Liebermann, 1955 [first list of grasshopper species of Brazil]. Steinmann, 1969 [list of species]. Barranco, 2010 [taxonomic comments].

Diagnosis: Pronotum subquadrate, many small denticles throughout the median carina of pronotum ( Fig. 4A ); anterior margin of median carina truncated and crest slightly arched, provide with two protuberances ( Fig. 4A ); crest almost straight, with only one curve ( Fig. 4B , dorsal view); femora robust and with small lappets throughout on its dorsal margin ( Fig. 4A ).

Redescription (Male holotype, Fig. 4 ): Body surface rugose and crest punctuated. Head. Lateral view ( Fig. 4A ): head and compound eyes inserted below median carina crest; protuberant and globose eyes with straight base; vertex and fastigium not visible between eyes; antennal groove situated below margin of compound eyes; facial carinae arched. Frontal view ( Fig. 4C ): fastigium of vertex straight; eyes laterally arranged on the head but not pedunculated; frontal costa conspicuous, the bifurcation and facial carina visible; both superior ocelli between facial carinae; antennal grooves placed beside facial carinae; both antennae missing. Dorsal view ( Fig. 4B ): vertex between eyes wider than eyes in horizontal and vertical diameter; supraocular lobe conspicuous; rectangularly shaped head. Pronotum. Macropronotal, rugose, subquadrate, erose, having irregular teeth and emarginations, many small denticles throughout the median carina of pronotum. Lateral view ( Fig. 4A ): anterior margin of pronotum truncated and crest slightly arched, provided with two tubercle protuberances; median carina crest projection begins to decline after surpassing apex of tegmina and then becomes thinner; prozonal carina and extralateral carina inconspicuous; ventral sinus and tegminal sinus present; lateral lobe rounded and slightly directed laterally; infrascapular area narrow, thin and shorter than fore tibiae; wings slightly longer than pronotum. Frontal view ( Fig. 4C ): lateral lobes of pronotum slightly projected and directed sideward. Dorsal view ( Fig. 4B ): median carina continuous and strongly elevated, straight, lateral lobes with rounded tip and small expansion. Sternomentum. Inconspicuous. Wings. ( Fig. 4A ): tegmina and wings visible; wing longer than pronotum; tegmina ovoid and elongated, slightly thinner than L. alticristatus and L. unicristatus , with rounded apex; tegmina without venation, but with small punctuations. Legs. Fore legs ( Fig. 4A, B ): dorsal and ventral margins of femur with undulated carinae, right leg missing. Middle legs ( Figs. 4 A–B): dorsal and ventral margins of femur with undulated carinae with a dorso-apical blunt spine. Hind legs ( Fig. 4A, B ): femur robust and with small lappets throughout, on its dorsal margin. Abdomen. Not visible on the type, completely covered by the pronotum (dorsal view) and hind femur (lateral view).

Measurements (all in mm). Body length from the tip of the frontal carinae to the end of the pronotum 14.89; pronotum length 13.38; pronotum height (from the lowest part of the lateral lobes to the highest part of the dorsum in lateral view) 5.94; pronotum width (dorsal view) 3.97; hind femur length 6.65; hind tibia length 4.73.

Sampling data ( Bruner (1910)): “The type and only specimen of the present species comes from Pará, Brazil, where it was taken during the month of July by H.H Smith”.

Original coloration description: “General color dark fuscous, with the apical half of the pronotum and hind femora tinged ferruginous”.

Current coloration: The same of original description.
