MATERIAL. ♂ ( ZISP), Vietnam, Quang Binh Province, mountains SW of Dong Hoi, My Duc, 20.III.1963 (O.N. Kabakov); ♀ ( SIEE), Thailand, Mae Hong Son Province, env. Pai, 19°21′42″N 98°27′46″E — 19°22′N 98°30′29″E, h~ 600 m, 27.IV–9. V.2013 (I. Melnik); ♀ ( ZISP), Nakhon Ratchasima Prov., env. of National park Khao Yai, 50–1000 m, 26.X–4. XI.2000 (A. V. Gorokhov, L.N. Anisyutkin); ♂ ( ZISP), with labels ‘Carin Chebà/ 900–1100 m./ L.Fea, V XII-[18]88’ [ Myanmar, Karenni State], ‘ Galerita / orientalis / S.Goeb. ’, ‘ Galerita / batesi Andr. / Kryzhanovskij det.’. Besides, ♀ (image at https:// galerie-insectes.org), ‘ Thailand, [? Phrae Province], Punjen’.

Aedeagus examined in two males, including one with everted and inflated internal sac.

DIAGNOSIS. A macropterous or polymorphic (up to apterous) species distinctive from G. japonica peregrina in having the body uniform black except red femora, with the head and antennae entirely black, combined with the elytral pubescence short and sparse, arranged in a single row on each side of elytral ridge; pronotal basal angles only slightly blunted. The pronotum is slender, PL/PW 1.09–1.20 (vs. 1.01–1.05), the elytra wider relative to the pronotum, and the genae distinctly longer (vs. shorter) than the eyes, GL/OL 1.04–1.21. Aedeagus is distinctive, too.

REDESCRIPTION. As for G. japonica peregrina except the following. Body ( Fig. 7 View Figs 7–9 ) macropterous, sometimes brachypterous to apterous, and black; only femora reddish-yellow but black apices and sometimes antennal scape reddish at base. Elytra dull, head and pronotum shiny, with microsculpture superficial on pronotal disc and almost obliterate on apical 1/2 head, more distinct behind and toward sides of pronotum.

Head barely longer, with genae longer than eyes. Frontal median carina shiny, convex and mostly short, barely extended to the level of eye mid-length.

Pronotum longer, subquadrate to cordate. Sides very slightly to distinctly sinuate in front of base, from slightly converging to diverging toward basal angles; these blunt and slightly obtuse to subacute, respectively. Median line fine, superficial to well impressed. Basolateral foveae deep and very short, sometimes longer and traceable in basal two fifths.

Elytral pubescence sparse, arranged in a single row on each side of elytral ridge, sometimes denser, forming two rows on each side of even ridge in basal third. Interval 3 with three discal setae.

Aedeagus ( Figs 28–29 View Figs 22–31 , 48–49 View Figs 44–65 , 72–74 View Figs 72–77 ): median lobe smooth ventrally, with a short and deep, preapical, ventromedial groove, apex in lateral view in form of a rounded, slightly oblong capitulum, with a minute, preapical, ventral tooth; left paramere oblong oviform, slightly wider at base than at rather a widely rounded apex, with slightly more rounded dorsal than ventral margin. Internal sac well differentiated, with distinct left and right basal bulbs, ventrobasal sclerite close to apex of median lobe, ten dorsomedial and 5–7 left lateral sclerites, basal lateral sclerite long and curved, situated at apex of left basal bulb, this latter at base with second, minute, lateral sclerite.

DISTRIBUTION. Eastern India (Assam: Shillong), northern Bangla Desh (Sylhet), Myanmar, Thailand, Vetnam.

Chaudoir, 1861: 556 (‘nord de l’Hindostan’); Andrewes, 1930: 168; Reichardt, 1965: 11 ( Galeritula ).

MATERIAL. 2♂♂ ( MSPU), ♀ ( ZISP): Central Nepal, env. Katmandu , Rhaniban Mt. Ridge, Nagarjun Mt., 15.IV– 5.V.1996 (P. Udovichenko). — Aedeagus, including everted and inflated internal sac, examined in males .

DIAGNOSIS. Very similar to G. japonica peregrina , from which it is distinguished by the body apterous, the head entirely pale, combined with the genae and the elytra slightly shorter and wider in male, GL/OL 0.99–1.03 (vs. 0.82–0.90), EL/EW 1.66 (vs. 1.77–1.87), EW/PW 1.72–1.76 (vs. 1.59–1.63); aedeagus is distinctive as well.

In addition to obligate aptery and difference in body colour, G. ruficeps differs from G. batesi as the most closely related species chiefly by the genae, the pronotum and the elytra being shorter.

REDESCRIPTION. Body ( Fig. 6 View Figs 4–6 ) apterous and black, head brown black ventrally, with gula and dorsum red; mandibles, clypeus except apical margin, and palps toward pale apices brown rather dark. Legs black, femora reddish-yellow but black apices. Antennae reddish-brown, rather pale, with apical 1/2 scape slightly infuscated or with antennomeres 2–4 and apical 2/5 scape black. Forebody very shiny due to meshed microsculpture obliterate or nearly so, being slightly more distinct along sides of pronotum; elytra dull, with microsculpture coarse. Head coarsely while pronotum moderately rugose-punctate; frontal foveae with sparse punctures.

Head quadrate and short, with genae parallel to each other just behind eyes. Frontal median carina short and shiny, narrower and slightly convex in front, wide and barely convex, with fine and sparse punctures, between eyes.

Pronotum convex up to lateral bead at middle, with lateral margin slightly yet widely explanate before and behind or throughout and not well separated from convex disc by basal fovea and by a vague sublateral line anteriorly. Sides slightly sinuate in front of base, very slightly converging to slightly diverging toward basal angles; these straight or very slightly obtuse and moderately rounded. Median line fine, slightly impressed, obliterate at base and at apex.

Elytra with sides more diverging apicad than in G. orientalis ; apices obliquely truncate, subangulate combined, indistinctly sinuate inside rounded outer angles; sutural angles blunt or rounded, with a small re-entrant angle in between, subacute to slightly obtuse, respectively. Pubescence dense and differentiated, forming single or 2–3, mostly two, uneven rows on each side of odd or even ridge, respectively.

Aedeagus ( Figs 50–51 View Figs 44–65 , 75–77 View Figs 72–77 ) is very similar to that of G. batesi : median lobe smooth ventrally at apex, with a subtle, preapical ventromedial tooth; preapical ventromedial groove short and deep. Internal sac more robust than that of G. japonica peregrina , with nine dorsomedial and 5–6 left lateral sclerites (vs. 12–14 and 6–9, respectively), these latter situated on the body of the sac, with the basalmost one being at apex of left bulb; ventrobasal sclerite adjoining apex of median lobe. Left paramere subovate to subtriangular.

DISTRIBUTION. Recorded [ Andrewes, 1930] in Uttarakhand (Almora, Nainital, Har Ki Dun), Northern India; Nepal.

COMMENTS. The fact that G. ruficeps and G. batesi have their aedeagi, including internal sacs, very similar in shape, as well as in structure, suggests much closer relationships between these two species than between either and the other similar species, G. orientalis and G. japonica . This also suggests that G. ruficeps is a fairly recent derivation of G. batesi , which has most likely resulted from the development of obligate aptery of the imago.
