Varitrella (Cantotrella) paraiso Gorochov , sp.n.

Figs 78–88 .

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, on leaf of bush at night, 10–19.II.2024, A. Gorochov, M. Omelko, I. Naumenko ( ZIN).

DESCRIPTION. Male (holotype). General appearance more or less similar to that of V. (C.) mindanao sp.n. but with following characters: coloration light yellowish with greyish tinge on dorsum of pterothorax, numerous but rather sparsely located and small dark grey to blackish spots on most part of body (on dorsal epicranial part, antennae, pronotum, tegmina, legs and cerci; Figs 85–88 ), more numerous and very small grey to light grey marks on most part of hind femur and on abdominal tergites, whitish small areas on dorsal tegminal field as well as between tegminal R and M, and almost transparent some tegminal membranes ( Fig. 88 ); head and pronotum comparatively long for this genus, with moderately small ocelli, scape approximately twice as wide as rostrum between antennal cavities, almost angular apex of this rostrum in profile, and pronotal disc barely wider than long as well as clearly narrowing to head ( Fig. 85 ); tegmina distinctly protruding beyond apices of hind femora and with venation as in Fig. 88 ; hind wings clearly protruding beyond tegminal apices; anal plate with poorly distinct (almost whitish) semimembranous median area near anterior edge and with a few shallow keellike folds on posterior portion ( Fig. 86 ); genital plate as in Fig. 87 . Genitalia most similar to those of V. (C.) conspersa and V. (C.) depressa from Philippines, but epiphallus with distinctly less convex middle part of dorsal edge in profile and less high dorsoapical processes, ectoparameral sclerotizations (each ectoparamere in all these species in form of low membranous lobe slightly and roundly projecting under epiphallic apices as well as having longitudinal sclerotized ribbon on inner surface) shorter than in V. (C.) conspersa and narrower (less high in profile) than in V. (C.) depressa , endoparameral apodemes with distinct apical widenings (absent in two latter congeners), formula also more deeply bifurcated than in these congeners, and rami much longer (compare Figs 78–82 and some published illustrations [ Gorochov, 2003: figs VII, 4–6, 14]); spermatophore with anchor having a pair of long lateral spine-like processes directed to globular ampulla ( Figs 83, 84 ).

Female unknown.

Length in mm. Body 21.5; body with wings 31; pronotum 3.2; tegmina 21; hind femora 14.

COMPARISON. The new species is most similar to V. (C.) conspersa and V. (C.) depressa in the structure of their male genitalia but differs from them in the above-mentioned (listed in the description) characters of these genitalia. From V. (C.) manukan , the new species is distinguished by the dorsoapical epiphallic processes dictinctly lower (shorter) and proximally wider in profile (for comparison see Figs 80, 81 and the published photograph [ Gorochov, Tan, 2014: fig. 55]), and from all other species of this genus, by a lighter coloration, longer head and pronotum, and a membranous sac-like ectoparamere having only inner sclerotized ribbon (vs the ectoparamere is completely sclerotized and articulated with the ventral epiphallic projection).

ETYMOLOGY. This species is named after the Paraiso

Camp situated very near its type locality.
