Abrodiaeta (Sclerodiaeta) propinqua, Gorochov, 2018

Abrodiaeta (Sclerodiaeta) propinqua View in CoL sp. nov.

(Figs 110, 131–134, 143–146)

Etymology. This name is the Latin word “propinqua ” (related, nearest), because the new species is similar to A. lanceolata in the shape of male last abdominal tergite.

Type material. Holotype – male, BRAZIL: Minas Gerais State [“ Minas Geraës ”], 1897, “ex coll. Fruhstorfer ”, “104-98”.

Description. Male (holotype). Body colouration light brown to yellowish but with brown eyes and rose dorsal tegminal field as well as with greenish tinge on rest part of tegmina and distal part of hind wings (probably mainly greenish in living condition). Head with slightly oblique anterior part in profile, with narrow rostrum having two small and simple tubercles (upper tubercle barely projected before lower tubercle, with somewhat widened and truncated apical part, and with dorsal surface having median groove and low lateral keels along dorsal edges of lateral ocelli; i.e. this tubercle almost as in Fig. 253 View Figs 241–256 ). Pronotum somewhat elongate, with oblique anterior half of ventral edge of lateral lobes and their posteroventral part round; humeral notch distinct but not narrow and not very deep ( Fig. 131 View Figs 131–142 ); disc convex (almost roundly semitubular) but with flat hind lobe having widely rounded (almost roundly truncated) posterior edge. Tegmina ( Fig. 132 View Figs 131–142 ) long and rather wide, with slightly arcuate proximal half of costal edge and arcuate most part of anal edge, with RS rather short and having two branches, with RA having two distinct branches in distal part, and with stridulatory apparatus as in Figs 110, 132 and 133; hind wings with distal parts distinctly protruding beyond tegminal apices (their structure as in Fig. 134 View Figs 131–142 ). Legs thin and rather long; all femora without spines, spinules or denticles (except for a pair of small apical denticles on hind femur); tibiae very thin, with several small spinules on ventral surface, with somewhat larger and more numerous spinules on dorsal surface of hind tibia, and with widened and flattened proximal part of fore tibia having oval (opened) and elongate tympana. Last abdominal tergite larger than other abdominal tergites, with wide and rather long posteromedian lobe directed backwards/downwards as well as having roundly angular notch at apex and concave dorsomedian part, and with a pair of notches around this lobe rather deep and narrow ( Figs 143, 145 View Figs 143–155 ); epiproct located behind this lobe, rather small but elongately triangular and with narrowly rounded apex ( Figs 143, 145 View Figs 143–155 ); paraprocts small and rounded; cerci rather short and bifurcated near their base (dorsolateral branch thicker and strongly curved medially, with two small denticles on lateral edge and at apex; ventromedial branch thinner and less arcuate but with hooked apical part; Figs 143–145 View Figs 143–155 ); genital plate rather long, with moderately narrow distal third having a pair of small finger-like posterolateral lobules and almost rounded notch between them ( Fig. 144 View Figs 143–155 ). Genitalia with large unpaired and asymmetrical sclerite (its shape as in Fig. 146 View Figs 143–155 ).

Female unknown.

Length (mm). Body 22.0; body with wings 38.0; pronotum 4.6; tegmina 32.0; hind femora 16.0.

Comparison. The new species is similar to A. (A.) lanceolata and A. (A.) macricula in the shape of its male last abdominal tergite but distinguished from these species by the characters given in the key to Abrodiaeta subgenera.
