description: Anabropsis (Apteranabropsis) papiliomaculata sp. nov., Chinese name DZLJḛē
(Figure 1)
Description. Male. Body medium-sized for the genus.
Head. Fastigium verticis protruding forwards, compressed laterally, about half as broad as scape, dorsal surface with a distinct longitudinal furrow along the midline. Occiput with an indistinct median carina. Ocelli conspicuous, elliptic, width about 1/2 of length (Fig. 1A–C, H–J).
Thorax. Pronotum glabrous, without longitudinal median carina (Fig. 1A, H), lateral lobes longer than deep, ventral margin oblique, humeral sinus absent. Wings absent, but with distinct wing rudiments of fore and hind wings (Fig. 1B, I). Prosternum with 1 pair of processes, basal area stout, apical area digitiform; mesosternum with 1 pair of processes, basal area stout, apical area spiny; metasternum with 1 pair of triangular processes, internal margins nearly straight, external margins slightly expanded, apices obtuse (Fig. 1G).
Legs. Fore coxa with 1 stout spine on anterior surface; mid coxa with a smaller spine on external surface. Fore and mid femora unarmed on ventral surfaces; hind femur with 4–6 spines on internal margin of ventral surface, external margin unarmed, genicular lobe with an internal spinule on apex. Fore tibia with an articulated spine near the middle of dorsal surface, 4 pairs of articulated spines on ventral surface, 1 pair of apical spurs on both dorsal and ventral surfaces separately, dorsal apical spurs longer than ventral ones; basal area of fore tibia with an oval, developed internal tympanum, the external one reduced. Mid tibia with 3 articulated spines on internal margin and 2 articulated spines on external margin of dorsal surface, 4 pairs of articulated spines on ventral surface, and 1 pair of apical spurs on both dorsal and ventral surfaces separately, dorsal apical spurs longer than ventral ones. Hind tibia with 9 pairs of spines on dorsal surface, 1 articulated spinule on internal margin and 2 articulated spinules on external margin of ventral surface, 1 pair of apical spurs on dorsal surface and 3 pairs of apical spurs on ventral surface, dorsal apical spurs longer than ventral ones.
Abdomen. Posterior margin of ninth abdominal tergite with a broad and shallow concavity in the middle, and a pair of semi-circular lateral processes (Fig. 1E). Posterior area of tenth abdominal tergite with a pair of sclerotized hooks on lateral margins, which upcurved and contiguous with the lateral processes of ninth abdominal tergite (Fig. 1F). Epiproct linguiform. Cerci conical, directed upwards, basal area stout, apical area thin, apices obtuse. Paraproct with 1 pair of long processes, basal area stout and connected, separating at the apical third and curved externally, apical area thin, apices obtuse, sclerotized, as long as cerci (Fig. 1E, F). Basal area of subgenital plate broad, apical area rectangular, posterior margin straight, apical area of subgenital plate width about 3/4 of its length. Styli cylindrical on ventral surface near lateral margins of subgenital plate, apices subacute (Fig. 1D).
Female. Body is generally similar to that of male. Subgenital plate roughly triangular, basal area broad, narrowing, apex acute (Fig. 1L). Ovipositor sclerotized, obviously upcurved, narrowing, basal area stout, dorsal valvulae with apices subacute, obviously longer than ventral ones (Fig. 1K).
Coloration. Body brown with black spots. Scape and pedicel yellowish, with dark spots on internal sides, pedicel brownish with dark brown rings. Eyes dark brown, ocelli yellowish. Occiput black. Pronotum yellow-brown, with a butterfly-shaped black large spot in the middle of disc, posterior margin of pronotum dark brown, with irregular yellowish spots. Posterior margins of meso-, metanotum and abdominal tergites with irregular yellowish spots. Thoracic and abdominal sternites yellow-brown. Ventral surface of male subgenital plate dark brown, lateral area pale. Female subgenital plate brown. Legs yellow, with brown spots.
Measurements (mm). BL: ♂ 24.0, ♀ 22.0. PL: ♂ 6.3, ♀ 6.2. HFL: ♂ 23.2, ♀ 21.8. HT: ♂ 22.0, ♀ 21.5. OvL: 14.6.
Material examined. Holotype: male, Fenshuiling, Jinping, Yunnan, 2024.VI.15, collected by Hao Xu. Paratype: 1 female, Fenshuiling, Jinping, Yunnan, 2024.VI.15, collected by Hao Xu.
Disrtibution. China (Yunnan).
Discussion. The new species is similar to Anabropsis (Apteranabropsis) ailaoshanica Gorochov, 2021, but disc of pronotum with a large butterfly-shaped black spot, external tympanum of foretibia reduced, basal areas of male paraproctal processes connected, male subgenital plate short and broad, width about 3/4 of length, and spiny apical area of female subgenital plate short, about 1/3 of length.
Etymology. The new species is named for a large butterfly-shaped black spot on disc of pronotum.
