description: Haplosymploce aurantiaca sp. n.
(Figs. 4–7, 18–36)
Description. Measurements (mm). Overall length: male 20.1–23.2, female 21.5–25.0; pronotum length×width: male 4.5–5.5×5.2–6.0, female 4.9–5.5×5.1–6.0; tegmen length: male 18.0–20.0, female 19.5–21.5.
Body size large, black. Ocellar spot pale. Maxillary palpi and labial palpi with apical parts yellowish. Antennae brownish yellow, cerci and T1–7 orangish yellow, T8–10 darker. The remaining portion black.
Interocular distance on vertex distinctly shorter than that between antennal sockets. Maxillary palpus with 4th segment almost as long as 5th segment, distinctly longer than 3rd segment. Pronotum suboval, widest at posterior one-third. Tegmen and hindwing fully developed, extending beyond the end of abdomen. Tegmen with mediocubital branches longitudinal or slightly oblique. Hindwing with Sc forked apically, RA three-branched, M simple or bifurcated apically, CuA with 6–7 complete and 3 incomplete branches. Front femur type A3, A4, B4, or intermediate between A and B, with 3 large apical spines.
Male. T1 of male abdomen specialized (Fig. 27), with a cluster of dense black setae at the middle, and with a pair of fossae, of which the front margin is setose; T7 with a pair of hollows at the middle (Fig. 28), which are close to each other, the front of the joint of the hollows with a cluster of dense and curved setae, the periphery of the hollows with sparse setae. Supra-anal plate (Fig. 29) symmetrical, hind margin protrudent; paraprocts (Fig. 29) dissimilar, right one with two apical processes of which the anterior one is flat and bears long hairs and the posterior one is curved and conical, left paraproct with apical part resembling two unequal horns, each paraproct with a fingerlike process (fp in Fig. 29) basally and the left one larger which bears two apical spines; long intercercal processes (ip in Fig. 29) similar, with pointed apex, curved downwards. Subgenital plate (Fig. 30) asymmetrical, left of hind margin slightly emarginated, each side of this area bearing a stylus respectively; styli cylindrical, right one with small spines and larger than the left. L3 (Fig. 31) covered by a spicular membrane; L2vm (Figs. 32–33) rod-like, curved near the pointed apex, near which is a black-setose membrane; R3 (Fig. 34) with a branch, R2 (Fig. 34) with 2 sclerites, one of which is curved.
Female (Figs. 35–36). Supra-anal plate (T10) chevron-like, front margin emarginate, hind margin protrudent and right-angular; paraprocts broad and similar. First valvule (v.I) pisciform, the ‘body’ slightly sclerotized, the end of the ‘fin’ to the ‘tail’ (base) is a slender sclerotized area on the ‘back’, blackish brown; second valvules (v.II) small and slender, fused basally; third valvule (v.III) with apical one-third weakly sclerotized and curved, middle portion constricted. Intercalary sclerite (intc.s.) small, resembling a willow leaf, apical part with a hyaline area. Paratergites (pt.) dissimilar, left one slender with a preapical spinous process and two small basal lobes which are not opposite to each other, right one foliated and broad. First valvifers (vlf.I) dissimilar, with small spines, right one fused with v.I and larger with lateral extension of which the basal portion is fused with basivalvula (bsv.). Basivalvulae (bsv.) similar in shape but dissimilar in color (i.e., the degree of sclerotization), left one pale yellow with several small spines, right one strongly sclerotized, brown, fused with vlf.I. Hind margin of subgenital plate with left and right halves respectively folded inwards (as indicated by arrows in Fig. 36).
Nymph. Body color thoroughly brownish yellow, younger instars paler whilst older instars darker. Eyes small, black.
Remarks. This species resembles H. nigra but can be distinguished by orangish cerci instead of black ones, and by the shape of right phallomere.
The adults were mostly caught in the light trap, this prove H. aurantiaca sp. n. to be a phototactic species; also it can be inferred that males are more likely to be attracted by lights than females since most of the specimens are males. On the other hand, the nymphs and some adults were found under the bark of dead wood or, rarely, in leaf litter, i.e., H. aurantiaca sp. n. is very likely to be a wood-feeding species. If so, this species and even this genus is quite different from other ectobiid cockroaches which are active ‘outdoors’, e.g., in boskage at night.
