Meshram, Naresh M., 2019, New record of the genus Bambusiphaga (Hemiptera: Delphacidae: Tropidocephalini) from India with description of a new species, Zootaxa 4658 (1), pp. 197-200 : 199

Bambusiphaga unispina sp. nov. ( Figs 1–8 )

Measurements (mm). Male 3.4 long, 0.5 wide across eyes, 0.6 wide across hind margin of pronotum.

Male ( Figs 1–8 ). Yellowish orange; vertex and face pale yellow. Eyes, tegulae, mesonotum, and abdominal tergites darker than remainder. Scutellum with black transverse vitta at hind margin. Tegulae black. Fore wings hyaline with dark coastal margin ( Figs 1–4 ).

Head obliquely rounded in front and 1.4x wider than pronotum. Vertex length 0.2x width across eyes; lateral carinae straight, submedian carinae uniting just before frons. Face 1.5x as long as wide; frontoclypeus broad, frontal suture reaching up to vertex, median carina extended up to anterior margin of vertex ( Fig. 3 ). Ocelli present. Fastigium rounded in lateral view. Frons somewhat rectangular shaped ( Fig. 4 ). Pronotum 0.3x as long as wide and 0.5x length of scutellum; lateral carinae progressively diverged and reaching hind margin ( Fig. 4 ). Mesonotum with median carinae reaching to tip of scutellum and lateral carinae.

Male genitalia. Pygofer longer than wide, dorsolateral margin slightly produced, ventral margin with round opening, without diaphragm. Segment 10 rounded, short, without lateroapical processes, housing inconspicuous segment 11 ( Figs 7, 8 ). Phallotheca attached to connective with emarginate base ( Fig. 5 ). Paramere slender, bulged basally and truncate apically ( Fig. 5 ). Phallobase uniform throughout but narrowed and curved at apex. Aedeagus broad basally, narrowed apically, with one long, caudal process, originating mid-ventrally, almost reaching apex of shaft with acute apex. Aedeagal shaft with mid-lateral spinelike process. Gonopore apical ( Figs 5, 6 ).

Type material: Holotype ♂, INDIA: Himachal Pradesh, Palampur , CSK-HPKV, 32°10’03”N 76°54’65”E, 10.viii.2018, on mercury vapour lamp Coll. Sunil ( NPC).

Remarks. Externally this new species closely resembles B. taiwanensis (Muir) but can be separated from the latter by the aedeagus broad basally, narrowed apically, with one long, caudal processs, originating mid-ventrally, almost reaching the apex of the shaft with acute apex; aedeagal shaft with mid-lateral spinelike process; and gonopore apical.

Etymology. The species name alludes to the presence of spine like process at the mid-lateral part of phallotheca.
