Dolichoderus sagmanotus Xu, Z., 2001

Little is known about the biology of Dolichoderus sagmanotus. The type material, a worker, was collected in semi-evergreen monsoon forest.

Identification

Xu (2001) - Close to Dolichoderus siggii from Thailand, but gaster black, head longer than broad, masticatory margin of mandible with 15 teeth, only 1/8 length of antennal scape surpassed occipital corner. Also close to Dolichoderus sibiricus, but the basal two segments of gaster each without a pair yellowish spots, dorsum of thorax and gaster with standing hairs, posterior margin of propodeum not concave.

Description

Worker

Holotype. TL 3.7, HL 0.90, HW 0.80, CI 89, SL 0.80, SI 100, PW 0.57, AL 1.17, ED 0.27.

Head longer than broad, narrowed forward. In full face view occipital margin straight, occipital corners rounded, lateral sides convex. Anterior margin of clypeus straight. Masticatory margin of mandible with 15 teeth. Scape of antenna surpassed occipital corner by about 1/8 of its length. Eyes large and convex. In profile view, pronotum weakly convex, without margin. Promesonotal suture shallowly impressed. Mesonotum evenly convex. Metanotal groove wide and deep. Dorsum of propodeum strongly convex, longer than declivity, posterodorsal corner formed an acute angle. Declivity concave and margined along the lateral and dorsal margins. Node of petiole thick and inclined forward, anterior face short and vertical, posterior face long and slope down, dorsal face roundly convex. In dorsal view posterior margin of propodeum complete and weakly convex. In front view upper margin of petiolar node weakly convex. Mandibles with dense micro-punctures and sparse large punctures. Clypeus densely and longitudinally striate. Head and·thorax foveolate. Foveolae of head relatively sparse, diameter of foveola about equal to distance between foveolae, interface with dense micro-punctures. Foveolae of thorax dense, interface formed coarse ruga-reticulation. Lower portion of lateral side of pronotum finely punctured. Lower portion of lateral side of mesonotum, lateral side of metanotum, and declivity of propodeum smooth and shining. Node of petiole finely and densely punctured. Gaster smooth and shining. Dorsum of head and body with sparse erect or suberect hairs and sparse decumbent pubescence, hairs on head shorter and relatively abundant. Scapes of antennae and tibiae of legs with sparse suberect hairs and sparse decumbent pubescence. Head, thorax, and petiole reddish brown. Mandibles, antennae, and legs yellowish brown. Eyes and gaster black.
