Figures 3 A–D
Lophotettix brevicristatus Hancock, 1909; pg. 388 [general description], female holotype (OUM); type locality: “ Brazil, South America”. Günther, 1938 [crest morphology comparison]. Steinmann, 1969 [list of species]. Barranco, 2010, Fig.2 [holotype image].
Diagnosis: Pronotum rounded, directed forwards, anterior margin of median carina concave before the crest, few small denticles throughout the median carina of pronotum (Fig. 3A) (less than in L. alticristatus); median carina almost straight and with two small ripples (Fig. 3B, dorsal view); femur robust and with lappets throughout on dorsal, ventral and external margins (Fig. 3A,B).
Redescription (Female holotype, Fig. 3): Body surface rugose. Head. Lateral view (Fig. 3A): head and compound eyes inserted below median carina crest; protuberant and globose eyes with straight base; fastigium not visible between eyes; antennal groove situated below margin of compound eyes; facial carinae arched. Frontal view (Fig. 3C): fastigium of vertex straight; eyes laterally arranged on the head, but not pedunculated; costa frontal conspicuous, the bifurcation and facial carina visible; both superior ocelli between facial carinae; antennal grooves placed beside facial carinae; antennae shaped as compressed segments, laterally expanding from the base to the apex; right antennae missing. Dorsal view (Fig. 3B): vertex between eyes wider than eyes in horizontal and vertical diameter; supraocular lobe conspicuous; rectangularly shaped head. Pronotum. Macropronotal, rugose, rounded and projected forwards with few small denticles throughout the median carina. Lateral view (Fig. 3A): anterior margin of median carina, rounded, concave before the crest with few small denticles throughout the median carina of pronotum; 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 triangular, with rounded apex directed laterally; infrascapular area narrow, thin and shorter than fore tibiae; wings shorter than pronotum. Frontal view (Fig. 3C): lateral lobes of pronotum projected and directed sidewards. Dorsal view (Fig. 3B): median carina continuous and elevated, lateral lobes with pointed and rounded expansion. Sternomentum. Inconspicuous. Wings. (Fig. 3A): tegmina and wings visible; wing shorter than pronotum; tegmina ovoid and elongated, slightly thinner than L. alticristatus and with rounded apex; tegmina with slightly marked venation and punctated. Legs. Fore legs (Fig. 3A,B): dorsal and ventral margin of femur with undulated carinae, tarsi missing. Middle legs (Fig. 3A,B): dorsal and ventral margins of femur with undulated carinae with a dorso-apical blunt spine; right tarsus missing. Hind legs (Figs. 3 A–B): femur robust and with lappets throughout, on dorsal, ventral and external margins; antegenicular tooth robust. 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 14.83; pronotum length 13.56; pronotum height (from the lowest part of the lateral lobes to the highest part of the dorsum in lateral view) 5.73; pronotum width (dorsal view) 5.40; hind femur length 6.63; hind tibia length 5.16.
Sampling data (Hancock, 1909): “One example from Brazil, South America, in the University Museum, Oxford.”
Original coloration description: “(…) the body strongly rugose, ferruginous; antennae (…) the last articles pale yellow”.
Current coloration: Similar to the original description but body darker.
Comments: This species is based on a single female specimen and the author did not designate the holotype in the original description. However, following the article 73.1.2 of ICZN that specimen is the holotype fixed by monotypy.
