Gorochov, A. V., 2021, Taxonomy of Podoscirtinae (Orthoptera: Gryllidae). Part 13: new taxa of the subtribe Podoscirtina from Africa, Zoosystematica Rossica (Zoosyst. Rossica) 30 (1), pp. 64-77 : 74-75

Parametrypa pubescens sp. nov.

( Figs 26–28 , 35–40 )

Holotype. Male ; South Africa, KwaZulu–Natal Prov., 50–60 km SW of Durban City, Vernon Crookes Nature Reserve, 200–400 m, remnants of forest along small river, on bush leaf at night, 23–26.I.2008, A. Gorochov & A. Sotshivko ( ZIN).

Paratype. Female; same data as for holotype ( ZIN) .

The holotype and paratype were collected as nymphs; the imagines were reared in March 2008.

Description. Male (holotype). Body moderately small, distinctly pubescent. Coloration almost uniformly light yellowish grey but with poorly distinct barely darker greyish pattern on head dorsum and on tergites, two pairs of small greyish brown stripes behind eyes and under them, darkish spots on scapes and sparse dots on legs, and without any distinct darkened stripes on tergites ( Fig. 35 ); hind leg with partly darkened tibia, tarsus and apical part of femur, as well as with rather large darkish dots on femur located almost only along its ventral edge ( Fig. 36 ).

Lateral ocelli small but larger than median ocellus; hind femur without spines; hind tibia dorsally with 4–5 outer and 5 inner articulated spines (in addition to apical spurs) similar to those of P. fortipes in size, and with numerous unarticulated denticles clearly smaller than in this species ( Fig. 37 ); hind basitarsus with two outer and one inner dorsal denticles (in addition to apical spurs); anal and genital plates as in Figs 38 and 39 . Genitalia with following features: epiphallus subquadratic, clearly narrower than in P. fortipes , possessing wider posterior notch; rachis more strongly protruding beyond epiphallus than in P. fortipes ; rami partly reduced ( Figs 26–28 ).

Female. General appearance as in male, but hind tibia with five pairs of articulated spines, hind basitarsus with two pairs of dorsal denticles, genital plate with rather short and nearly angular apical notch ( Fig. 40 ); ovipositor approximately 1.1 times as long as hind femur.

Length (in mm). Body: male 18, female 16; pronotum: male 3.2, female 3.5; hind femora: male 10.8, female 11.6 mm; ovipositor 12.8.

Comparison. Differences of Parametrypa pubescens sp. nov. from its congeners are given in the key below. In addition, the new species probably also differs from the type species of this genus in the male genital characters mentioned in the description above [according to Chopard (1955), the male genitalia of P. fortipes have the epiphallus transversally triangular and with a moderately narrow posterior notch, the rachis distinctly but not strongly protruding beyond epiphallus, and the rami well-developed and rather long].

Etymology. The species name is the Latin adjective pubescens (pubescent or hairy).
