8. Galerita quadraticollis Fedorenko , sp.n.

Figs 14 View Figs 13–15 , 55 View Figs 44–65 , 90–92 View Figs 90–95 .

MATERIAL. Holotype ♂ ( ZMMU), with label: ‘ Vietnam / prov[ince]. Ha Tinh / Vu Quang (Phu Quon)/ [Nature] reserve, h~ 1.200 m / 5–26.VIII.1997 / leg. M. Kalyakin’. Paratype ♀ ( ZISP), labelled: ‘ Vietnam , Ha Tinh Prov.,/ Rao An, April-May 2000/ N.L. Orlov’ .

DIAGNOSIS. An apterous black species from Central Vietnam, with the pronotum slender, the pubescence similar in odd and even elytral intervals, the genae long, no or subtle impression on vertex, and the aedeagus distinctive.

DESCRIPTION. As for G. rufofemorata sp.n. except the following. BL 23.8–26 mm. Body ( Fig. 14 View Figs 13–15 ) black.

Head coarsely and densely punctate in basal half, with frontal carina traceable up to the level of eye mid-length and shallow (♀) or no (♂) impression on vertex.

Pronotum broadest between a third and two fifths from apex, moderately and very densely to confluently punctate, with sides parallel-sided or very slightly diverging toward base in basal fifth. Base truncate, with angles subacute to right, blunt or slightly rounded at apices. Apex more or less evenly sinuate or nearly straight at middle; angles more or less projecting, blunt or rounded. Median line fine and indistinctly impressed, obliterate in basal and apical sixths. Basolateral foveae in form of finely impressed lines traceable in basal half and extended apicad into very fine sublateral lines separating disc from slightly reflexed lateral margins; these being explanate and wide, about a fifth as wide as pronotum medially and a sixth as wide as pronotum at base and at apex. Lateral bead fine throughout.

Elytral apices obliquely truncate and angulate combined, each subsinuate inside outer angle; sutural angle sharp, almost right in male, very acute and extended into a short blunt tooth in female. Pubescence fairly dense, more so basally, thereby forming two uneven rows on each side of intervals 2–4 and 6 in basal third and on the inside of interval 8 in male (while 1–2 rows in female); otherwise arranged in a single row of fairly dense setae on each side of elytral ridge; the outside of basal 2/3 ridge 8 with setae forming two rows behind to three rows before. Interval 3 with 4–5 discal setae.

Aedeagus ( Figs 55 View Figs 44–65 , 90–92 View Figs 90–95 ): left paramere oviform, with both dorsal and ventral margins subequally rounded and apex narrowly rounded. Internal sac simple, without laterobasal bulbs, with eleven dorsomedial and four left lateral sclerites.

DISTRIBUTION. Only recorded here in Ha Tinh Province, Central Vietnam.

NAME. Refers to an oblong and subquadrate pronotum of this species.

HABITATS AND HABITS. The adults were hand collected in monsoon forests.

COMMENTS. While having the aedeagus very similar to that of the holotype, a male specimen from the adjacent province Quang Binh and a female specimen from an adjacent locality are slightly different from the type specimens of G. quadraticollis sp.n. in body shape and proportions.Accordingly I have to describe those two as belonging to a southern subspecies of the species discussed.

8a. Galerita quadraticollis subcordata Fedorenko , ssp.n.

Figs 15 View Figs 13–15 , 56 View Figs 44–65 .

MATERIAL. Holotype ♂ ( ZMMU), with label: ‘ Vietnam, C[entral]. Annam,/ prov. Quan [g] Binh,/ Minh Hoa [= Quy Dat] distr., Ke Bang / 8 km SO [=SE] env. Yen Hop / 2-8. IV.1999 (Dalat campus)/ leg. S. Kruskop’ . Paratype ♀ ( SIEE), labeled: ‘ Vietnam, Quang Binh Prov. [ince]/ Phong Nha - Kebang N [ational]P[ark],/ Bo Trach , h~ 400 m / 17°25′31″N 106°13′44″E / h = 1050 m, 23.IV–11. V./ leg. D. Fedorenko GoogleMaps 2019’.

DIAGNOSIS. Different from the nominotypical subspecies in having the body slightly more robust, the pronotum more cordate, i.e., shorter, PL/PW 1.09–1.13 (vs. 1.20–1.28), with sides more rounded and more deeply sinuate in front of base, this being narrower, PB/PA 1.31–1.39 (vs. 1.43–1.54), and the elytra barely shorter, EL/EW 1.71 or 1.68 (vs. 1.75 or 1.74) in male and female, respectively. Left paramere by comparison is narrower, with ventral margin only slightly rounded ( Fig. 56 View Figs 44–65 ).

DESCRIPTION. Body as in Fig. 15 View Figs 13–15 , BL 23–25.6 mm. Head with a shallow impression on vertex in female. Pronotum with basal angles subacute and blunt or slightly rounded at apices. Elytral apices similar, except that sutural angles not toothed in female. Aedeagus as in Figs 90–92 View Figs 90–95 , except that six left lateral sclerites are present.

DISTRIBUTION. Quang Binh Province, Central Vietnam.

NAME. Refers to the pronotum, which is much more cordiform than in the nominotypical subspecies.

HABITATS AND HABITS. As for the nominotypical subspecies.
