Abstract

Glenea coomani Pic, 1926 distributed in Vietnam, Laos and China is redescribed, and its sibling species, Glenea neohumerosa sp. n. is described from China (Guangxi, Hainan and Fujian) and North Vietnam. They are separated from each otherby differences in genitalia, and apical teeth and maculae of elytra. Another four related species and one subspecies are illustrated with short notes and new localities, and the lectotype and paralectotype of Glenea tonkinea Aurivillius, 1925 are designated. A key to the related species is presented.

Introduction

Glenea coomani Pic, 1926 was originally described from North Vietnam, and Glenea humerosa Gressitt, 1940, described from Hainan Island, China had been synonymized with it by Breuning (1956). In the course of our study of saperdine beetles from South China, we confirmedtheir conspecific status based on the study of the type material. However, we surprisingly found another species, which had been identified as Glenea coomani or Glenea humerosa by predecessors. This new species is distinguishable from Glenea coomani by having different elytral maculae, longer elytral apical teeth, and differing structure of male genitalia. Therefore, we describe Glenea neohumerosa sp. n., and compare it with Glenea coomani which is redescribed. We show the habitus of similar species which are compared with short notes and new localities. The following species are mentioned and keyed: Glenea coomani Pic, 1926, Glenea neohumerosa sp. n., Glenea lacteomaculata Schwarzer, 1925, Glenea lacteomaculata quadriguttata Pic, 1926, Glenea laodice Thomson, 1879, Glenea subalcyone Breuning, 1964, Glenea tonkinea Aurivillius, 1925.

Redescription.

Male (Figs 2–6): length: 11.5–14.2 mm, humeral width: 3.5–4.5 mm. Female (Fig. 1): length: 14.0–16.2 mm, humeral width: 4.5–5.4 mm. Body black, in part provided with white to pale yellow pubescent maculae. Head with white to pale yellow maculae on genae, borders of eyes, temple and two parallel stripes between upper eye lobes; antennae black, with thin, whitish pubescence on inner sides of first three segments and base of fourth segment, and scattered with short, black bristles on undersides of first seven segments. Prothorax with a medial white to pale yellow stripe, and each side white to pale yellow (Fig. 1a). Scutellum white to pale yellow. Elytra with suture narrowly white to pale yellow near base; each disc with 5 white to pale yellow maculae: a large oval spot close to suture at the end of basal 1/4; a smallest spot near the middle, far from suture; the third one large, oval, close to suture just behind the middle; the fourth medium in size, round, far from suture; an oblique transverse band just before apex. Ventral surface covered with dense white to pale yellow pubescence, thinly so along middle. Legs black, thinly pubescent. Pronotum and elytral bases with sparse, erect, black bristles.

Head hardly broader than prothorax, deeply, and in part densely punctured, feebly concave at vertex. Eyes deeply emarginate, inferior eye lobes subequal to (female), or 2 times as high as (male) genae below it, width much less than half of front. Antennae longer than body; scape slightly thickened apical without cicatrix nor a ridge; antennomere ratio (male): 12 : 3 : 21 : 16 : 16 : 15 : 14 : 13 : 13 : 12 : 13; (female): 15 : 4 : 24 : 17 : 17 : 16 : 15 : 14 : 14 : 13 : 13. Prothorax almost as broad as long (male) or broader than long (female), swollen laterally before middle; disc convex and somewhat deeply and closely punctured. Elytra prominently angulate at humeri, slightly narrowed apically; each with 2 humeral longitudinal ridges beginning after humeri and reaching near the apex, truncated apically, with short and small teeth at the suture and the outer angle, surface with coarse and irregular punctures. Legs stout, middle tibiae grooved, hind femur reaching fourth abdominal segment, first hind tarsal segment longer than (male), or nearly as long as (female) following two segments combined. Male claws: the anterior claws of the fore and mid tarsi are toothed at the base, but the tooth in the fore tarsus is very small (Fig. 5), the tooth in the mid tarsus is long (Fig. 6, almost same size of the normal claw). Female claws simple.

Male genitalia (Figs 7–11): Tegmen length about 3.0 mm; lateral lobes stout, each about 0.6 mm long and 0.3 mm wide, with fine haired ridge at the base (in ventral view), apex nearly truncated and with fine setae which are shorter than lateral lobes; ringed part elbowed in the widest portion, converging; basal piece bifurcated distally (Fig. 9); median lobe plus median struts moderately curved, a little longer than tegmen (6:5); the median struts about one half of the whole length of median lobe; dorsal plate shorter than ventral plate; apex of ventral plate narrowly pointed, with sharp apex which is always curved to right side (in ventral view, Fig. 10); median foramen elongated triangular, with a small projection in lateral view; internal sac about 3 times as long as median lobe plus median struts, with 4 pieces of basal armature, 2 bands of supporting armature and 3 rods; the two longer rods each about 1.6 mm, shorter than tegmen, the short middle rod about 1.1 mm long. Ejaculatory duct single. Tergite VIII (Fig. 8c) broader than long, apex truncated with middle slightly projected, setae near lateral corner dense and long, and sparse and short around middle.

Diagnosis.

Differs from Glenea lacteomaculata Schwarzer, 1925 (Fig. 24), Glenea lacteomaculata quadriguttata Pic, 1926 (Figs 25–26) and Glenea tonkinea Aurivillius, 1925 (Figs 3033) in elytron having only one big oval macula at basal fourth, instead of two small spots, the second macula smallest instead of the first one. Differs from Glenea laodice Thomson, 1879 (Fig. 27) and Glenea subalcyone Breuning, 1964 (Figs 28–29) in elytron without long and sharp tooth at the outer angle, having only one big oval macula at basal fourth, instead of two spots.

Remarks.

Based on the study on the types and material from type localities, we agreed with Breuning (1956) that Glenea humerosa Gressitt, 1940 is conspecific with Glenea coomani Pic, 1926. Though the holotype of Glenea humerosa Gressitt (Fig. 2) has the middle oval pubescent spot reaching suture and seems to be different from the type of Glenea coomani Pic (Fig. 1), the male (Fig. 4) also from Hainan Island looks no different from those from Tonkin. Nevertheless, such pubescent markings are quite variable in shape and size within same species.

Remarks.

Due to lack of material from Taiwan, the differences between Glenea lacteomaculata Schwarzer, 1925 and Glenea lacteomaculata quadriguttata Pic, 1926 are doubtful for the authors. The specimens from Guangxi and Yunnan provinces are conspecific to Glenea lacteomaculata quadriguttata and herein the new localities are reported.

Diagnosis.

Differs from Glenea pici Aurivillius in having pubescent maculae white; in having different male claws. Differs from Glenea lacteomaculata Schwarzer in having spot at middle of elytron transverse, anterior claw in mid tarsus of male with long tooth (Fig. 31).

Lectotype designation.

According to Aurivillius' original description, there were multiple type specimens, deposited in “Reichsmuseum in Stockholm und Collectio Pic". In order to fix the species concept and ensure universal and consistent interpretation of this species, we designate the male specimen in MNHN as the lectotype (Figs 30–31, 8.5 mm long, 2.4 mm wide) and the female in NHRS as the paralectotype (Fig. 33) of Glenea tonkinea Aurivillius.

Remarks.

The record from Taiwan is doubtful. It might be based on Glenea diversenotata Schwarzer, whose taxonomic position was not clear yet.

Discussion

The above species are grouped as Glenea coomani group by the following characters (not meant to be presumed synapomorphies, but rather only for identification of species having similar makings): pronotum largely black, generally with a white or yellow median stripe; body covered with pubescence instead of metallic squama (such as the metallic green maculae of Glenea pici Aurivillius, 1925); elytron black with an apical spot and 4 or 5 unequal sized spots. They differ from Glenea relicta group by elytral spots (not include the band just before apex) with unequal size and located in different position.

Key to species of Glenea coomani group

Elytral apex having a long and sharp spine at the outer angle (much longer than that at the inner angle, Fig. 35) 4
2 Elytron having only one big oval macula at basal fourth; the second macula located behind the basal one smallest (Figs 1–4) Glenea coomani
Elytron having two small spots at basal fourth, the first spot is the smallest one 3
3 Elytral apex truncate or slightly emarginate, the middle spot on elytron almost rounded (Figs 25–26) or somewhat transverse (still far from suture, Fig. 24); male with apex of tergite VIII truncate Glenea lacteomaculata (including the subspecies Glenea lacteomaculata quadriguttata)
Elytral apex obliquely truncate, the middle spot on elytron transverse and oblique (almost touching sutural stripe, Figs 3033); male with apex of tergite VIII doubly emarginate (with a middle projection) Glenea tonkinea
4 Elytron having 5 white or yellow maculae; legs black (Figs 12–15) Glenea neohumerosa sp. n.
Elytron having 6 white or yellowbrown maculae 5
