Pseudotruljalia speciosa pulchra subsp. nov.

( Figs 6–9, 16–20, 25–28)

Holotype. Male, Uganda, Western Region, Bundibugyo Distr., environs of Semuliki National Park , ~ 500 m, forest, at light, 12–14.III.2020, A. Gorochov, G. Irisov ( ZIN).

Paratypes. One male, 2 females, same data as for holotype ( ZIN) ; 1 male, Uganda, Western Region, Bushenyi Distr., environs of Kalinzu Nature Reserve , ~ 1000 m, forest, at light, 23–28.II.2020, A. Gorochov, G. Irisov ( ZIN) .

Description. Male (holotype). General appearance very similar to that of P. speciosa speciosa Gorochov, 2005 but with following differences: coloration of epicranium almost as in this species, i. e., yellowish with two pairs of brown stripes along dorsomedial and ventromedial edges of antennal cavities ( Fig. 6), light brown to brown upper halves of genae and more distinct dark brown longitudinal stripes on hind half of dorsum ( Fig. 7); mouthparts (including palpi) more uniformly yellowish with only light brown marks near dorsolateral edges of labrum; antenna with slightly longer yellowish dorsoproximal stripe (this stripe almost as fore femur in length) and with other parts brown but having less distinct small lightish spots after this yellowish part; pronotum with slightly larger black central spot and more contrasting (dark brown to blackish) other spots on yellowish disc ( Fig. 7), and its lateral lobes uniformly brown; tegminal colouration as in Fig. 16; legs with fore and middle femora brown, hind femur light brown but having short apical area dark, tibiae and tarsi dark brown but having light brown most part of inner surface of fore tibia and dorsal half of hind tibia as well as brown marks on middle tibia and almost light brown dorsal spots on all tarsi; pterothoracic and abdominal tergites as well as pleurites and anal plate light brown with almost completely blackish posterior tergites, dark brown ventrolateral spots on more anterior abdominal tergites and dark stripes along posterolateral edges of anal plate ( Fig. 17); cercus dark greyish brown with light brown base; venter of body (including coxae and genital plate) yellowish; structure of body distinguished from that of nominotypical subspecies by somewhat short- er pronotum with wider anterior part of disc (see Figs 7 and 10), shorter concave part of metanotal gland before a pair of central tubercles (see Figs 8 and 11), and genitalia with epiphallus, rachis and especially epiphallic ectoparameres also somewhat shorter (see Figs 25–27 and 29).

Variations. Paratype from environs of Kalinzu Nature Reserve with light brown proximal half of cercus and hardly larger tubercles of metanotal gland ( Fig. 9).

Female. Size, colouration and structure of body similar to those of males, but: stridulatory apparatus and metanotal gland absent; dorsal tegminal field with 10–11 longitudinal veins (which slightly oblique in proximal part and somewhat S-shaped in middle part) and rather numerous crossveins, with colouration from brown (with sparse small lightish spots) to light greyish brown (with dark- er venation and slightly darkened proximal and some lateral membranes); lateral tegminal field with rather narrow Sc-R area and 10–11 more or less oblique Sc branches as well as numerous but poorly distinct crossveins (coloration of this field light brown with contrasting brown longitudinal venation). Genital plate and ovipositor as in Figs 18–20; their colouration from yellowish to light brownish grey, but ovipositor with a pair of dark brown lateral longitudinal stripes and blackish apical (drilling) parts.

Length in mm. Body: male 12–14, female 13– 13.5; body with wings: male 22–23.5, female 23– 24.5; pronotum: male 2.4–2.6, female 2.7–2.8; tegmina: male 15.5–16.5, female 16–17; hind femora: male 8.3–8.8, female 8.4–8.7; ovipositor 8.5–8.7.

Comparison. This new subspecies differs from P. s. speciosa from Cameroon in the male pronotum somewhat shorter and less narrowing to the head ( Figs 7 and 10), the metanotal gland with a shorter anterior concave part ( Figs 8, 9 and 11), the male genitalia with some structures slightly longer, and the colouration of some body parts more contrasting or lighter: the both head dorsum and pronotal disc have more contrasting stripes and spots, the pronotal lateral lobes are uniformly brown (vs. blackish with brown central area), and the legs are lighter (in nominotypical subspecies: fore leg and hind tibia as well as middle tibia and tarsus dark brown, except for brown spines and spurs of latter tibia; middle and hind femora with rather long dark brown distal portions; rest part of middle tibia as well as hind tarsus brown). I cannot exclude also that P. s. pulchra may be a separate species closely related to P. speciosa .

Etymology. The new subspecies name is the Latin word “pulchra” (nice) in connection with a nice body colouration having contrasting stripes and spots.
