Hypsipyrgias joseliae, Lis & Lis, 2021

Lis, Barbara & Lis, Jerzy A., 2021, Hypsipyrgias joseliae, a new species of lace bugs (Heteroptera: Tingidae: Tinginae) from New Guinea with a key to species of the genus Hypsipyrgias, and comments on three allied genera Hypsipyrgias Kirkaldy, 1908, Diplocysta Horváth, 1925, and Hypsotingis Drake, 1960, Zootaxa 4958 (1), pp. 327-333 : 329-330

Hypsipyrgias joseliae sp. n.

( Figs 1–4 , 7 )

Etymology: The new species name is derived from the first name of Jocelia Grazia, a distinguished specialist on South American Heteroptera .

Diagnosis: In general habitus ( Fig. 1 ), the new species resembles the other two species of the genus, but can easily be separated from H. telamonides by having a pronotal hood distinctly smaller ( Fig. 2 ), not covering the anterior part of the lateral carinae in dorsal view, at most concealing the posterior part of the head. Additionally, the frontal cephalic spines of the new species are very short ( Fig. 2 ) whereas in both, H. telamonides and H. euphues they are long, reaching the apex of the first antennal segment ( Figs 5–6 ). In H. euphues the shape and size of the pronotal hood are very similar to the new species but it differs in the shape of hemelytra and its discoidal area, as well as in characters related to pronotum (for details, see the key for species identification).

Description: Measurements (in mm): body length 3.48–3.80, maximum body width 1.10–1.25, length of pronotum 1.36–1.55, maximum width of pronotum 0.92–1.20, length of hemelytron 2.60–3.00, length of discoidal area 1.26–1.37, length of antennal segments 0.16–0.18: 0.11: 1.03–1.17: 0.38–0.44.

Body ( Fig. 1 ) oblong with lateral margins almost parallel, only slightly sinuated at the level of distal apices of discoidal areas. General color brownish; head, pronotal disc, abdomen and thoracic sterna black; cephalic spines, bucculae, sternal laminae, antennae and legs yellowish brown, fourth antennal segment and apices of tarsi dark brown to black. Body covered with short, whitish, curly hair, especially visible on the pronotal disc and the ventral side of the thorax.

Head short ( Fig. 3 ), armed with five cephalic spines, occipital spines relatively long, appressed, subparallel, dorsomedial spine very short, porrect, frontal spines short, porrect, placed very closely each other. Bucculae rounded apically, closed in front ( Fig. 4 ), each buccula composed of three rows of tiny areolae. Antennae slender, third antennal segment about 2.5–3 times as long as the fourth, antenniferous tubercles short, obtuse. Labium surpassing posterior margin of mesosternum, sternal lamine low, uniseriate, open behind ( Fig. 4 ).

Pronotal disc convex, coarsely punctate, tricarinate, each carina composed of one row of areolae. Lateral carinae distinctly sinuated and terminating at the level of the highest point of pronotal disc ( Fig. 1 ). Median carina fusioning with the pronotal cyst (hood). Pronotal cyst as high as its width, pyriform, not covering the head, composed of relatively large, polygonal areolae ( Fig. 2 ). Triangular pronotal projection areolate, without any tumid area at apex. Paranota composed of four rows of areolae at their widest part, three inner rows of polygonal areolae raised, outer row reflexed, resting on the pronotal surface, composed of regular, trapezoidal areolae. Collar composed of two rows of areolae.

Hemelytra ( Fig. 1 ) long, their lateral margins slightly sinuated, costal area composed of one row of relatively large, rectangular areolae, subcostal area narrow, almost vertical, composed of two rows of small, rounded areolae, discoidal area more than twice shorter than hemelytron, composed of seven to eight rows of areolae, sutural area composed of five to six rows of large areolae, hypocosta uniseriate. Legs slender.
