sp. n.

[9] Calleida borneensis Shi & Casale  , sp. n.

Type locality: Borneo: Sarawak, Bidi.

Type material: Holotype, male, " Borneo : Sabah, Keningau district, Jungle Girl Camp , N5.4430, E116.4512;

1182m; Shi H.L. & Liu Y. lgt., light trap, Ins. Zoo., CAS. 2 016.IV.24N " (NHML, fig. 61View FIGURES 61–66). Paratypes: two females, same data as holotype but date 2016. IV.25 N and 2016. IV.29 N ( IZAS); one teneral male, " Borneo: Sabah, Keningau district, Jungle Girl Camp, N5.4430, E116.4512; 1182m; Yuan F. lgt., Malaise trap, Ins. Zoo., CAS. 2016. IV.25 " ( IZAS); one male, “ Sarawak: Bidi 23.iii.1909 C.J. Brooks. B.M. 1936-681” ( NHML, fig. 62View FIGURES 61–66).


Specific epithet. This new species is named from its type locality, the island of Borneo.

Diagnosis. The new species is distinct from all the other known Asiatic Calleida  species based on the following character combination: medium sized (L: 8.4–9.9 mm). Head and pronotum piceous or dark brown, with very faint greenish reflections; elytra metallic green, with reddish purple reflections. Elytral apex strongly curved, outer apical angles markedly widened, but not forming acute angles ( fig. 16View FIGURES 1–18). Abdominal sternum VII in male normally notched at middle, with one seta on each side in males, two setae in females. Median lobe of aedeagus without any prominent ventral lobe, apical lamina elongate, capitate and securiform ( fig. 64View FIGURES 61–66).

It is very similar to and sympatric with C. corporaali Andrewes in Borneo  , but distinguishable by: the size smaller; the elytral microsculpture vanished; the elytral outer apical angles obtuse, not forming sharp angles; the abdominal sternum VII moderately notched; and the very different male genitalia. The new species is also similar in coloration and sympatric with C. tenuis  ( C. splendidula  group), but distinguishable by: body size larger; elytral microsculpture vanished; elytral apex markedly curved, outer apical angles widened; median lobe of aedeagus with capitate apical lamina.

Description. General features: ( figs. 61, 62View FIGURES 61–66) Medium sized species: L: 8.4–9.9 mm; TL: 8.0– 9.4 mm.

Colour: head, pronotum, femora, tibiae and underside piceous to dark brownish, head with vague reddish patch on vertex, pronotum with very faint metallic greenish reflections; apex of palpi and lateral margins of pronotum testaceous; antennomeres 1–3 reddish, 4–11 dark brown, tarsomeres and trochanters reddish brown; elytra bright metallic green, dull on apical two-thirds of inner two intervals, with reddish purple reflections at shoulders, lateral sides and near apex.

Lustre and microsculpture: meshes of the microsculpture isodiametric, very faint on the head, vanished on pronotum and elytra.

Head wide, flat, smooth; genae markedly constricted to the neck; frontal foveae shallow, sub-striate in front, ending in a rounded depression on each side; eyes prominent, hemispherical.

Pronotum subquadrate-cordate (ratio PW/PL: 1.06–1.11); base oblique at sides, wider than anterior margin. Anterior angles rounded; lateral margins reflexed, rounded in front and slightly or markedly sinuate in front of the posterior angles which are rectangular, not projecting laterally. Disc with very faint transverse wrinkles; median furrow deep, reaching the base; basal foveae very deep.

Elytra depressed, elongate (ratio EL/EW: 1.69–1.78), faintly dilated behind. Striae fine, finely but deeply punctate; intervals slightly convex, flattened on disc; interval 8 dilated near apex into a smooth rounded callosity. Elytral apex obliquely truncate, truncation distinctly curved; the outer apical angles markedly widened, obtusely rounded, not forming acute or prominent angles.

Underside glabrous and shinning. Abdominal sternum VII in male normally notched at middle, with one seta on each side in males; two setae in females.

Male genitalia: as in fig. 64View FIGURES 61–66. Median lobe of aedeagus of peculiar shape: ventral margin markedly sinuate in lateral aspect; in ventral aspect, middle part distinctly dilated, and then gradually narrowed to apex; apical lamina very developed, much longer than the basal width, capitate and axe-shaped in dorsal and ventral aspect, hooked in lateral aspect. Endophallus with two chitinized copulatory pieces close to the left lateral margin of the median lobe, close to each other at base, V-shaped; the ventral one longer, sinuate and acicular at apex, apex adjacent to the base of the apical orifice; the dorsal one shorter and wider. Left paramere dorsally depressed, two times as long as wide; right paramere slightly emarginate. ( fig. 65View FIGURES 61–66)

Female genitalia (reproductive tract fig. 63View FIGURES 61–66 and ovipositor fig. 66View FIGURES 61–66): spermatheca digitiform, one third as long as the pedicel; surface very weakly whorled, with large stout basal projection; spermathecal pedicel straight at base, then strongly bisinuate, S-shaped, with a small apical protuberance; spermathecal gland duct about as long as spermatheca, laterally inserted on the basal projection; glandular area slightly thickened, about twice length as gland duct, base with gradually protuberant atrium. Gonocoxite II of ovipositor three times as long as the basal width, slightly narrowed to apex, apex truncate, a little oblique; inner margin setose from the middle to apex; outer margin a little curved; apex with short membranous extension.

Geographical distribution and habitat. Only known from Borneo: Sarawak and Sabah, Malaysia ( map 5View MAP 5) in tropical rain forest. Some specimens were collected by light trap.

Remark s. In the original description of C. corporaali, Andrewes (1929)  wrote that he examined one further specimen from North Borneo, Kudat, “which is smaller in size and narrower, with a touch of deep red at the apex of elytra, so that it approaches more nearly to C. terminata  ”. This specimen was cited (Sabah: Kudat) as C. corporaali  by Stork (1986). Maybe, it should belong to C. borneensis  .

Andrewes (1931a), in his monograph on the Carabidae  of the Mt. Kinabalu (Sabah), didn’t cite any Calleida  species. But, according to the present contribution, at least four species are distributed in Sabah: C. borneensis  , C. corporaali  , C. tenuis  and C. gressittiana  , two of which are endemic to Borneo.
