description
(Figs. 1, 2) Description. Body length (including tegmina), male: 6.6 mm. Body color yellowish brown. Fore margin of crown (Fig. 1, A, B, D) with two black circular spots close to both sides of eyes, anterior margin with upper margin dark tawny, lower margin with broad black stripes. Face (Fig. 1, C) with frontoclypeus with black short transverse striations and two black long longitudinal stripes, extended to near apex of anteclypeus, lateral margin black; anteclypeus base black; lora near base and apex black brown; antennal sockets black. Anterior margin of pronotum (Fig. 1, A, B, D) with six black circular spots in transverse row. Forewings (Fig. 1, A, E) with veins black brown, cells and apex marked with tawny patches or striations. Legs (Fig. 1, A, B, C, E, F) yellow to brown. Head (Fig. 1, A, B, D) broader than pronotum. Crown (Fig. 1, A, B) with fore margin rounded, middle length nearly equivalent to next to eyes, anterior margin with broad transverse sulcus, ocelli on anterior margin of head, close to corresponding eye. Face (Fig. 1, C) with anteclypeus inflated distally; antennal pits shallow, antennal ledges weak; gena region coarse. Middle and hind region of pronotum (Fig. 1, A, B, D) rough. Forewing (Fig. 1, A, E) with broad appendix. Fore femur with anteromedial (AM 1) seta present and with an additional proximal seta, intercalary (IC) row with fine long setae, anteroventral (AV) row with short macrosetae on ventral margin; spinulation of protibia dorsal surface with 7 + 7 setae. Male pygofer side (Fig. 2, G) strongly prolonged, with numerous long macrosetae near caudal margin, apically rounded and produced. Valve (Fig. 2, H, I) equilateral triangular. Subgenital plate (Fig. 2, H, I) with lateral margin expanded near the middle and with short fine setae, constricted distally, apical process stubby and apical margin emarginate. Style (Fig. 2, H, I, J) with apical process thick and long digitate, lateral margin with short fine microsetae, apex truncate and ventral margin with three tiny blunt teeth, lateral lobe prominent. Connective (Fig. 2, H, K, L) Y-shaped; stem articulated with long pseudostyles; pseudostyles conspicuously extended posteroventrally, with a pair of large triangular curled lamellate processes arising from lateroventral surface near apical 1 / 3, lateral margin of process with small serrations; pseudostyles constricted and narrow apically, apex tapered, pointed and curved, bent subapically, apices crossing, and margin with small dentate processes extending to apex. Aedeagus (Fig. 2, G) situated dorsad of connective and linked to it by a thin membrane from nearly mid-length of pseudostyles. Aedeagal shaft (Fig. 2, G, M, N) tubular, slightly dorsad curved, apex with dorsal surface with small short lateral process slightly extended anterolaterad; dorsoatrium developed, nearly as long as shaft, strikingly bifurcated apically in ventral view; gonopore (Fig. 2, N) large, nearly median to apical on ventral surface. Anal tube (Fig. 2, G) small. Female: unknown.
discussion
Remarks. This new species is similar to A. hobohmi Theron, 1988, but it can be distinguished from the latter by the following characters: anterior margin of pronotum with three pairs of black circular spots in transverse row (with pair of small black spots behind eyes in A. hobohmi); style with apical process with three tiny blunt teeth at apex (with a small angular process at apex in A. hobohmi); connective with pseudostyles basally bifurcate, with a pair of triangular lamellate processes arising from lateroventral surface near apical 1 / 3, lateral margin of process with small serrations (pseudostyles sub-basally bifurcate, without triangular lamellate process, with weak serrations arising from subapical to distal region and strongly sclerotized in A. hobohmi).
etymology
Etymology. This new specific epithet originates from the Latin word “ serriformis ” referring to pseudostyles with lateral margin of triangular lamellate process and subapical margin all having small serrations.
