Ordo: Blattodea
Familia: Blaberidae
Genus: Rhabdoblatta
Name
Rhabdoblatta maculata Yang & Wang & Zhou & Wang & Che, 2019 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Diagnosis
This species is similar to Rhabdoblattaomei Bey-Bienko, 1958, but can be differentiated by the following characters: 1) body wider with darker spots on pronotum and tegmina (body narrower with pale spots on pronotum and tegmina in the latter); 2) the hind margin of subgenital plate slightly concave and nearly symmetrical (the latter with the hind margin obviously concave and asymmetrical); and 3) outer-lateral margin apex of L3 with carina blunt and rounded (sharp and acute in the latter).
Measurements (mm)
Male, head: length × width 4.8 × 5.0, pronotum: length × width 7.8 × 10.0, tegmen length: 39.1, overall length: 41.7–43.5.
Description
Male. Body yellow (Figure 6A). Vertex, eyes, and frons black. The apex of clypeus yellow, the remaining black. Ocelli yellow. Scape of antennae brown, the 2nd–15th segments dark brown, other segments pale brown. Mandible and labrum yellow. Maxillary palpi brown (Figure 6B). Pronotum yellow, with an irregular and symmetrical dark brown marking at disc, and with messy and dense brown spots on the border, posterior margin with longitudinal short stripes (Figure 6C). Tegmina yellow, with numerous scattered dark brown or brown spots. Wings pale gray, veins yellowish brown (Figure 6E, F). Legs reddish brown. Abdominal sterna brown. Cerci dark brown (Figure 6B). Vertex slightly exposed (Figure 6B). Distance between eyes slightly narrower than interocular width, length ca. 1/2 of the space of antennal socket (Figure 6B). Pronotum subelliptical, the anterior and lateral margins rounded, middle of hind margin distinctly convex (Figure 6C). Tegmina and wings fully developed extending well beyond the end of the abdomen, the apex of the tegmina with a convex and wings blunt and rounded (Figure 6A, B, E, F). Anteroventral margin of front femur type B2 (Figure 6D). The metatarsus of hind leg equal length to sum of left tarsi, the inner margin with two rows of small spines. Tarsal pulvilli present on the 1st–4th of the tarsomere apex, with 1–2 spines. The pretarsus with arolium, claws symmetrical and unspecialized (Figure 6B).
Male genitalia. Supra-anal plate nearly semicircular, lateral margins rounded, the middle of the hind margin slightly concave. Right and left paraprocts unsymmetrical, shape similar to other members in this genus (Figure 6G). Subgenital plate with hind margin nearly symmetrical, right part with concavity. The base of the inner plate bifurcated. Styli flat, length ca. 1/3 of interstyli space (Figure 6H). The apex of the sclerite R1T peaked, end of R2 rounded, R3 and R5 interlinked; R4 existing independently (Figure 6I). The basal sclerite of L2D slender and rod-shaped; apical sclerite short and small, the surface on the apical membrane with fine bristles, cap-shaped (Figure 6J). Sclerite L3 long, with blunt and rounded carina; inner margin with groove and a tooth-shaped convexity at apex (Figure 6K).
Female. Female unknown.
Etymology
This species epithet is derived from the Latin word maculatus, referring to the tegmina having clear spots.
