Tan, Ming Kai, Gorochov, Andrej V. & Wahab, Rodzay Bin Haji Abdul, 2017, New taxa and notes of katydids from the tribe Meconematini (Orthoptera: Meconematinae) from Brunei Darussalam, Zootaxa 4337 (3) : -

Genus Pulchroteratura , new genus

Type species: P. huiqing sp. nov., by monotypy.

Diagnosis. Head distinctly hypognathous, with very short rostral tubercle between scapi and long apical segment of maxillary palpi (this segment slightly longer than subapical one); pronotum elongated, lacking distinct humeral notches, with rather deep lateral lobes and elongated posterior lobe ( Figs. 4A, 4B ; 5A, 5B); wings long, strongly protruding behind apices of hind femora; hind wings not protruding behind tegminal apices; legs thin and long, typical of Meconematini ( Figs. 4A, 4B ), with fore leg lacking coxal spur and having large tympana open and ovoid in shape. Male last abdominal tergite with almost truncated posterior edge (having very shallow median concavity); male epiproct and paraprocts very small and rounded; male cerci moderately elongated not widened, with two small lobules (one medial lobule and one dorsal lobule) in middle part and depressed (almost lamellar) distal part having rounded apex; male subgenital plate with rather wide proximal part and narrow distal part; latter part with a pair of apical finger-like styles which located near each other, directed downwards and separated by suture from this plate ( Figs. 5C–G ); male genitalia completely membranous.

Included species. Type species only.

Comparison. This genus is most similar to Pseudoteratura Gorochov, 1998 in general appearance ( Fig. 4 ), but is distinguished from the latter genus by the characteristic features of head rostrum and abdominal apex listed above (in the diagnosis).

Etymology. The name of this new genus originates from the Latin word “pulchrus” (nice) and generic name Teratura in connection with its nice colouration.
