description: Phaloria? jerelynae Gorochov et Tan, new species
(Figs 11, 12, 19, 20, 35–43)
Material examined. Holotype (male): Singapore, Bukit Timah Nature Reserve, along main road Hindhede Drive, near Simpang Hut, secondary forest, 19 May 2011, coll. M.K. Tan & L.F. Cheong.
Paratypes: Singapore: 1 male, same locality as for holotype, 24 October 2011, M.K. Tan, R.W.J. Ngiam & L.F. Cheong; 1 male, same locality, 8 January 2012, coll. M.K. Tan & J.J.Y. Chan; 1 male, same locality, 22 February 2012, coll. M.K. Tan.
Diagnosis. This species differs from representatives of the subgenera Phaloria and Papuloria Gorochov (Gorochov, 1996) in the absence of additional lobes, lobules and hooks between posterolateral processes of epiphallus and on their inner sides. It differs from a single species of the subgenus Sulaweloria Gorochov (Gorochov, 2011) in the guiding rod completely sclerotized and not fused with endoparameres as well as posterolateral epiphallic processes much longer and median (anterior) part of epiphallus distinctly longer (not in shape of transverse ribbon). These differences of the new species do not allow us to understand its systematic position; it may be a specialized representative of Phaloria s. str. or of Papuloria, but also it may belong to a new subgenus of Phaloria s. l. or to a new genus of Phaloriini.
Description. Male holotype. General appearance more or less similar to that of Tremellia timah (as in Figs 35–37), but distinguished by following characters of coloration and external body structure: pronotum purple with lateral lobes having two distinct yellowish spots (these spots occupying about half of lateral lobes; as in Fig. 36); abdominal tergites yellowish but irregularly marbled greyish purple; abdominal sternites and subgenital plate greyish purple; fore tibia with inner tympanum slightly smaller than in Tremellia timah (Fig. 11) and with outer tympanum almost equal to inner one in size; length of longest inner distal spine 1.5 mm; length of longest inner dorsal spur 2.9 mm.
Tegmina with 7 oblique veins in dorsal field (2 proximal oblique veins small), with mirror slightly less transverse than in Tremellia timah and having distal dividing vein sinuous, with apical area very short, with lateral field having about 24 branches of Sc and 7 crossveins between R and M (as in Fig. 38); stridulatory vein of right tegmen weakly arcuate and with 18–19 stridulatory teeth per mm at median region of this vein (Fig. 42); anal plate with dorsolateral ridges, with shallow concavity near middle and with distal part obtusely truncate and emarginate; subgenital plate with proximal half wide and with distal half narrowed; apex of this plate almost truncate but with small posteromedian notch (Fig. 12).
Genitalia: epiphallus moderately long in median (anterior) part and with a pair of very long posterolateral processes having weak subapical widening and apical part directed partly aside; ectoparameres moderately large, elongate, lobe-like, and with distal part somewhat twisted; endoparameres large, with posterolateral arms strong but not long, with apodemes rather long, and with medial projections comparatively short and not fused with each other; guiding rod in shape of rather small and elongate plate not fused with mold of spermatophore attachment plate; this mold moderately long and not wide, with deep posteromedian notch (as in Figs. 19, 20, 39–41); rami gently convex with short ends pointing inwards.
Variations. Right tegmina of some paratypes with 8 oblique veins in dorsal field.
Female. Unknown.
Measurements. See Table 3.
Etymology. The species is named in honour of Chan Jia Yee Jerelyn, a friend of the junior author.
Remarks. Calling song was recorded in-situ on 24 October 2011 at about 2015 hours. The calling song is a series of repeated double chirps with frequency of 4.0–4.5 kHz (Fig. 43). Each chirp lasts 0.12– 0.13 s (mean = 0.12 s) and consists of 7–8 peaks (mean = 7). Pauses between each chirp last 0.16– 0.20 s (mean = 0.17 s). Pauses between each series last 0.86– 1.38 s (mean = 1.11 s). The southern part of Malacca is here indicated as a possible most western locality for the genus Phaloria Stål, excepting only very widely distributed (from Java to Seychelles) Phaloria insularis.
