Varitrella (Cantotrella) sympatrica Gorochov , sp.n.

Figs 66–68 , 75–77 .

MATERIAL EXAMINED. Holotype ♂, Philippines, Luzon I., ~ 120 km NNE of Manila City, environs of Paraiso Camp (15º39′33′′ N, 121º16′37′′ E), 500–800 m, forest, at light, 10–19.II.2023, A. Gorochov, M. Omelko, I. Naumenko ( ZIN).

DESCRIPTION. Male (holotype). Coloration and structure of body very similar to those of V. (C.) contraria sp.n. but with following differences: dark grey part of head dorsum with a pair of short yellowish longitudinal lines located near occiput between larger yellowish longitudinal stripes; each eye light grey to yellowish with three longitudinal brown stripes in dorsal half; antennae with larger dark areas on scapes; rest of head as in male paratype of this species but with more numerous darkish dots on epicranium under antennal cavities and without distinct dark marks near (under) rostral apex as well as with almost completely dark grey three distal segments of maxillary palpi; tegmina brown with dark brown some areas, light brown very narrow stripes along many veins and veinlets, smaller white spot near mirror apex, rather wide yellowish/whitish humeral stripe and narrow stripe along almost two thirds of anal edge of lateral field, and somewhat darkened membranes of intercalary triangle ( Fig. 66 ); rest of body light grey with darkish (grey) dorsal surface of hind femur, dark grey spots on this femur along its ventral edge and apical parts of all femora as well as most part of all tibiae and tarsi (but fore and middle tibiae with small lighter marks, hind tibia also with lighter spines, and tarsi with lighter apical segments and some parts of other segments), grey to almost dark grey abdominal tergites and median parts of sternites, blackish anal plate having brownish grey semimembranous area ( Fig. 68 ), as well as with grey genital plate having slightly darker median longitudinal band and a pair of posterolateral ones on ventral surface ( Fig. 67 ); external structure of body distinguished only by insignificantly shorter tegmina ( Fig. 66 ), slightly wider semimembranous area on anal plate ( Fig. 68 ) and more angular distal part of genital plate ( Fig. 67 ); genitalia more different in structure ( Figs 75–77 ): epiphallus wider in anterior half and with distinctly higher dorsoapical processes as well as with much more angular ventroapical corners in profile, ectoparameres much longer, endoparameral apodemes less projecting before anterior part of epiphallus, ventroapical lobules of rachis with clearly wider proximal halves, and rami with partly reduced posterior portions.

Female unknown.

Length in mm. Body 15.5; body with wings 26; pronotum 3.5; tegmina 17.5; hind femora 13.3.

COMPARISON. The new species is most similar to V. (C.) contraria sp.n. but with its male genitalia very different (these differences are given in the description above). From all other congeners, the new species differs in the same characters as the latter species (except for the ectoparameral length which is almost as long as in V. (C.) quadrata , but from the latter species, the new one differs in much higher dorsoapical epiphallic processes).

ETYMOLOGY. This name is the Latin biological term “sympatrica ” (sympatric, living in the same locality), because this species was collected in the same locality as V. (C.) contraria sp.n.
