Aleuromarginatus sulawesiensis Dubey sp. nov.

( Figure 15 )– Figure 18 (d))

Puparium (n = 10, 5 female, 5 male)

Broadly elongate oval ( Figure 15 )); sexually dimorphic, female puparia were larger than males, female 1560–1620 µm long, 1100–1150 µm wide, male 1120–1210 µm long, 740– 850 µm wide.

Margin

Crenulate ( Figure 15 ), Figure 16 (a,b,c)), 3 crenulations per 0.1 mm. Thoracic tracheal combs absent or with 3 modified teeth at pro-mesothoracic suture area. Caudal tracheal comb area slightly depressed.

Dorsum

Granulated. Dorsal surface generally without tubercles, only the submedian area with faint tubercles. Submedian area pigmented. Submargin with a row of papillae, overlapping marginal crenulations. Longitudinal moulting suture reaching margin and transverse moulting suture reaching submarginal lines. A pair of lateral longitudinal furrows with rectangular tubercles present on submedian area of cephalothorax and abdomen, 282 µm apart. Cephalothoracic and abdominal segment sutures prominent. Abdominal segment sutures reaching near longitudinal furrows on submedian area but extending farther towards margin ( Figure 16 )). A row of tubercles present in sutures of each abdominal segment on subdorsal area. Distance from posterior margin of vasiform orifice to caudal tracheal comb opening ( Figure 16 )) 257–290 µm in females, 175–195 µm in males. The median length of the cephalothorax was slightly smaller than that of the abdomen, cephalothorax 600– 740 µm long in female puparia, 540–600 µm long in males, and abdomen 850–880 µm long in females and 580–610 µm long in males. The median length of the mesothorax (102– 112 µm in females, 80–87 µm in males) was greater (22–25 µm) than that of the metathorax (80–87 µm in females, 60–62 µm in males). The median length of abdominal segment VII was half that of segment VI ( Figure 15 ), Figure 16 (e)). Median length of abdominal segment IV equal or subequal to that of segment III. Median lengths of abdominal segments I–VIII: I 62–70, II 65–67, III 82–87, IV 85–90, V 77–82, VI 75, VII 35–40, VIII 50–75 µm in females, and I 47–52, II 50–55, III 55–60, IV 55–60, V 50–57, VI 47–75, VII 27–30, VIII 42–57 µm in males. Pockets discontinuous, occupying posterior half of segment VI, 12–15 µm in median length. A row of simple pores present along the bases of submarginal papillae forming 45 pairs. Cephalothorax with 4–5 and abdominal segments with 3–4 simple pores between lateral longitudinal furrows on submedian area ( Figure 16 )).

Vasiform orifice

Subcordate ( Figure 15 ), Figure 16 (g)). Females 62–70 µm long, 60–65 µm wide; males 50– 55 µm long, 52–55 µm wide; operculum in females 32–37 µm long,50–52 µm wide; males 30– 64 µm long, 40–45 µm wide; lingula exposed, not reaching beyond posterior margin of the vasiform orifice, 10–12 µm long.

Venter

A pair of ventral eighth abdominal setae present, 25–32 µm long, 62–70 µm apart in females, 12–20 µm long, 47–52 µm apart in males, ventral setae located posterolateral to vasiform orifice. Antennae extending to outside of prothoracic legs ( Figure 15 )), reaching 1/4th of mesothoracic legs, 127–142 µm long in females, 110–127 µm long in males.

Chaetotaxy

Anterior marginal setae absent. Posterior marginal setae 15–20 µm long. Dorsum with 21 pairs of hook-shaped setae, sometimes simple setae, 11 pairs on cephalothorax and 10 pairs on abdomen, 12–17 µm long. Of the 11 pairs located on cephalothorax, 2 pairs on cephalic margin and prothorax, 1 pair each on meso-, and metathorax and 4–5 pairs on submarginal area. Of the 10 pairs located on abdomen, 1 pair located on submedian area of abdominal segment I (first abdominal setae), segments III–VI and segment VIII (eighth abdominal setae) (except the segments II and VII), and 3 pairs on posterior-lateral of vasiform orifice and 1 pair on submarginal area of abdominal segment II.

Adult male (n = 1) ( Figure 17a –e ))

Eyes divided ( Figure 17 )). Antennae 7-segmented (I–VII) ( Figure 17 )), 272 µm long: I 21, II 27, III 80, IV 20, V 10, VI 85, VII 70 µm long; apical setae present. Vasiform orifice 37 µm long, 45 µm wide; operculum deformed in mounting. Lingula tonguelike, 32 µm long. Four pairs of abdominal wax plates ( Figure 17 )): I 50–52 µm long, 107–112 µm wide, 105 µm apart; II 57–58 µm long, 117–127 µm wide, 85 µm apart; III 50–60 µm long, 110–120 µm wide, 85 µm apart; IV 50 µm long, 72–100 µm wide, 95 µm apart. Claspers ( Figure 17 )), 122–127 µm long. Aedeagus 107 µm long.

Adult female (n = 2) ( Figure 18 (a–d))

Eyes divided. Antennae ( Figure 18 )) 7-segmented (I–VII): I 32, II 67, III 100–103, IV 25, V 14, VI overlapped, VII 65 µm long; apical setae present. Vasiform orifice 57–70 µm long, 67 µm wide; operculum 42 µm long, 55 µm wide. Lingula tongue-like, 40–50 µm long. Two pairs of abdominal wax plates ( Figure 18 )): I 112–115 µm long, 200–215 µm wide, 127 µm apart; II 120–125 µm long, 230–232 µm wide, 100 µm apart. Cement glands with 4 constrictions ( Figure 18 )).

Material examined

Holotype ‘puparium’; Sulawesi Utara: Pulau Bunamen near Manado , 3 puparia under one coverslip (slide 1), on Papillionaceae host with smooth leaved coastal shrub, 22 June 1985, J. H. Martin ( NHM 5041 ). The top puparium from the first row is selected as the holotype and the two puparia from second row are paratypes.

Paratypes

Date same as for the holotype. Nineteen puparia under three cover slips (2 with the holotype; 3 female, 5 male on slide 2; 6 female, 3 male puparia on slide 3); 4 adult females and 1 adult male under one cover slip (slide 4).

Host plant

A Papillionaceae host with smooth leaves.

Distribution

Sulawesi.

Etymology

The species is named after the country of the type locality, Sulawesi.

Remarks

Puparia of this species differ from those of A. martini sp. nov. in pigmentation, extension of abdominal segment sutures to subdorsal area, and the presence of more submedian/ subdorsal setae and in lacking eye spots.
