Body length.

Holotype, 7.4 mm.

Description.

Crown ( Fig. 13, 14 View Figures 2–14 ) elongate, median length approximately six-tenths of interocular and half of transocular width; median longitudinal carina well developed. Male pygofer ( Fig. 34 View Figures 31–36 ) with ventral appendage short, spiniform, produced posteriorly beyond pygofer lobe apex. Valve short, rectangular. Subgenital plate ( Fig. 34 View Figures 31–36 ) extended posteriorly beyond pygofer lobe apex by approximately one-third lobe length, with numerous long, fine setae distributed evenly over entire length of dorsum. Connective ( Fig. 35 View Figures 31–36 ) Y-shaped; without dorsal median keel or median anterior lobe. Style ( Fig. 28 View Figures 21–30 ) slender, tapering towards apex; apex directed laterally, with several denticuli preapically. Aedeagus ( Figs 35, 36 View Figures 31–36 ) with ventral paraphysis-like structure with pair of elongate, recurved distal processes expanded preapically; dorsal part without sclerotized apodemes, consisting only of shaft, shaft strongly compressed, extended posterad, abruptly bent dorsad in distal third, distal part sinuate. Anal tube ( Fig. 34 View Figures 31–36 ) segment X with pair of posterolateral lobes each bearing small spine and several denticuli and at base with separately articulated robust process with pygofer, extended ventrad and terminating in anteriorly directed spine.

Coloration.

Stramineous to white ( Figs 14 View Figures 2–14 , 15 View Figures 15–20 ). Crown ( Fig. 14 View Figures 2–14 ) with paired black markings at base of crown and paired maculae at apex of crown. Etymology. The specific epithet, “kintendela”, means “cicada” in Kongo language ( Bentley 1895).

Notes.

Signoretia kintendela sp. n. shares with other members of the pacifica group ( Linnavuori 1978) the fusion of the aedeagal shaft to the paraphyses-like structure consisting of the robust and sclerotized paired basal aedeagal appendages and elongate preatrium. If the robust process interpreted herein as arising from the membrane between the anal tube and pygofer lobe was viewed as an anal tube appendage by Linnavuori (1978), then in the pacifica group, the new species is more similar to Signoretia congoensis and Signoretia augur because these species share a single pair of processes at base of the anal tube. Nevertheless, the new species can be distinguished from these and all other Signoretia by the shorter ventrocaudal processes of the pygofer lobe and very long and slender rami of basal appendages with sinuous and foliaceous apex.
