Male As in A. fungicola and A. flava with specialisations on T2 (but these are wider, with more complicated ridges), distinguished by the arrangement of the surface bristles of T2-5 in one transversal line. Female: Well characterized by the combined occurrence of two features: bristles of T2-5 arranged in one strict transversal line, and T6,7 with only few and rather small bristles. The latter feature is also shared by A. fungicola , which, however, has dispersed surface bristles on T2-5. The species A. sinuosocarinata and A. multisetosa resemble A. paucisetosa in the first feature, but are distinguished by having numerous surface bristles on T6,7 and by differences in the laterosternal shelf area.


The species name refers to the few (Latin: pauci) bristles (Latin: setae) being present on T6,7.


Size Length of body (in alcohol): male 2.7-3.43 mm, female 2.61-3.49 mm. Surface bristles of tergites 2-5 strictly arranged in one straight transversal row, only on T2 near the lateral borders bristles often less regularly distributed (Fig. 9A, B, E View Figure 9 ). Transversal ridges tr2-5 without distinct small excurvations to the anterior (Fig. 9B, E View Figure 9 ; compare grey arrows in Fig. 11A View Figure 11 ), but male tr2 posteriorly of the specialisations with a wide excurvation to the posterior, mesally followed by a wide, very shallow excurvation to the anterior (grey arrows in Fig. 9B View Figure 9 ).

Male Tegmina (Fig. 3I, J View Figure 3 (A–J) ) widest at about 1/2 of length; obtusely wedge-shaped due to the roughly converging course of the basalmost part of the posterior border and the apical border, connecting curvature similarly short as in A. fungicola ; basalmost part of posterior border and the oblique apical border slightly concave; surface bristles rather fine (as in A. flava but longer and at a lower density). Hindwings fairly rhombic, with obtuse apex (Fig. 1H View Figure 1 ). Glandular pores on T1-5 in the area between the transversal ridge and the anterior border, dispersed, in moderately high density (Fig. 5E, F View Figure 5 ). Tergite 1 with long bristles on surface and borders (like T2-5); without specialisations. Tergite 2 along the anterior border with a pair of specialisations (msl2) consisting of a shallow, fairly wide transversal trough the bottom of which is patterned by low crossing ridges that are more complicated than in A. flava and A. fungicola , forming a net-like relief (Figs 5E, F View Figure 5 , 9B View Figure 9 ). Tergites 6,7: (Figs 9C View Figure 9 , 13E View Figure 13 , 15D, E, K View Figure 15 (larval)) Median lobe of T7 very short, but distinct; transversal ridge tr6 well developed, tr7 absent; posterior border of T6 and T7 with a row of relatively long and thin bristles, distinctly shorter and thinner than those at the respective lateral borders; surface of T6 and T7 only with few isolated and small bristles, still smaller than those at the posterior borders. Subgenital lobe: (Figs 25A, B View Figure 25 , 26C View Figure 26 ) distal part with a deep excavation each along left side and right side; lobe posterior to level of excavations narrowly tongue-shaped and inclined leftward; only left stylus present (sll), which is conical, inserted at base of excavation, not reaching tip of lobe; at the base of the right excavation with a group of short and strong bristles; distal lobe and stylus with few rather long and thin bristles. Phallomeres: (Figs 25A, B View Figure 25 , 26C View Figure 26 ) Sclerotised part of hook (h) from the short, wide base (b) suddenly narrowing into a slender neck (n) widely and uniformly curved from the beginning, terminating in a slightly wider claw part (cl). Endophallic apodeme (ea) not narrowed at base (forking site of sclerite). Relative to the axis of the endophallic apodeme (ea), the virga (vi) shows a weak, angular proximal bend to the left, its apical part being hardly curved (not fully back into the ea -axis) and gradually narrowed to a fairly stout tip; virga likely longitudinally grooved. Paraprocts: Both lacking a sclerotised projection (Figs 5K View Figure 5 , 9D View Figure 9 ).

Female Tergites 6,7: (Figs 9F View Figure 9 , 12E View Figure 12 , 14E View Figure 14 , 15L View Figure 15 (larval)) Median lobe of T7 rather long; transversal ridges tr6 and tr7 complete, tr6 sublaterally with a weak, but distinct bend; surface bristles very few, of medium size or smaller; focused to central part of surface area. Subgenital plate (Figs 16E, F View Figure 16 , 18H, I View Figure 18 ) rounded-rectangular, with parallel lateral borders; lateral parts of transversal ridge (sr7-l) with a weak mesally directed curvation, lateral terminal parts with a weak laterally directed curvation; ridge mesally ending well after having reached a transversal orientation, close to a bristle-bearing point upon it, with a moderately wide median gap, recurved sr7-m ends indicating the ridge to be bisinuate. Genitalia: (Figs 20A, B View Figure 20 , 22H View Figure 22 ) Spermathecal plate sp small, pouch gcp fairly small (Fig. 20A, B View Figure 20 ). In laterosternal shelf sclerite (Figs 20A View Figure 20 , 22H View Figure 22 ) central part (c) fairly long and posteriorly rounded, posterior and lateral margins of central part and arms together forming a quite evenly curved horseshoe arch, arms (a) fairly wide, wing parts (w) fairly narrow, their base restricted to posterior half of tubes (blue arrowhead); tubes (lst) narrowed towards the anterior and curved mesad. Mesal gonangulum sclerites (gg-m) distinct, lateral ones absent (Fig. 20B View Figure 20 ).
