AMERICAN NEOSCONA AND CORRECTIONS TO
PREVIOUS REVISIONS OF NEOTROPICAL ORB-WEAVERS (ARANEAE: ARANEIDAE)
Museum of Comparative Zoology
One of the first revisions of American araneids was that of Neoscona (Berman and Levi, 1971). At the time I was undecided whether to revise the Nearctic and Neotropical species together or separately. Soon it became evident that, although undesirable, a geographic division had to be made. Most of the Nearctic species were well represented in collections but there were only a few specimens of the Neotropical species. Collections of the American Museum of Natural History and the Museum of Comparative Zool- ogy were the main ones used. At present large collections of Neotropical spiders are available on loan which we did not have in 1970. Grasshoff's revision (1986) of African Neoscona found that Africa and America share some species but that Africa has species belonging to the subgenus Afraranea which are not found in the Americas. But since most of the Neoscona species are found in the area of eastern Asia and western Pacific, our knowledge of Neoscona species is still limited. Neoscona species are easily transported and are part of the unfortunate homogenization of the world fauna. I suspect that the new Neoscona marcanoi from His- paniola, and N. oaxacensis (Keyserling) may be the only native species found in the American tropics. This paper is an addition to the previous revision (Berman and Levi, 1971). The records of specimens included in previous maps (Berman and Levi, 1971) have not been individually listed; most came either from the AMNH or MCZ collections. In the present paper, the previous localities are plotted again, together with the new records, which are listed together with their collections. p~

This paper also includes corrections and additions to previous monographs. After completion of a generic revision, I invariably get specimens sent to me that cannot be determined with my keys and illustrations. Most turn out to be new species. Also I find omissions, errors and misprints. However, the omission of a previ- ously described species, and perhaps one whose genitalia have not been illustrated before, may lead to a redescription as a new species and a possible later synonymy. Also some species turn out to be misplaced, a discovery made only after a specimen of the other sex becomes known. This also has to be corrected. Credits.

Neoscona Simon, 1864: 261. Type species designated by F. P.- Cambridge, 1904: Epeira arabesca F. P.-Cambridge. Diagnosis. Male palpal patella with two macrosetae and with oval median apophysis of palpus bearing a proximal "upper" recurved tooth (similar in all species, M in Fig. 6). Neoscona dif- fers from other araneid genera with two palpal macrosetae (Ara- neus, Aculepeira, Larinia, Metepeira) by the structure of the palpus (Figs. 6-8, 16; 1971, figs. 4-6): a large area of the bulb is a folded basal hematodocha (H), and only a small area has sclerites.
224 Psyche [VOI. 99
Unlike in other genera, the sclerites are partly hidden by a wide cymbium (Y, Fig. 6) which touches a small median apophysis (M); the radix is fused to the stipes or has a joint; the stipes is distally three-partite with a conical embolus (E), an embolus lamella (L), and a terminal apophysis (A), the last two only lightly sclerotized. There is almost no distal hematodocha between embolus and termi- nal apophysis.
Female Neoscona differ from other genera by a curved, spatula- shaped epigynum whose sclerites appear fused (Figs. 1-3). The epigynum of N. nautica (Fig. 10) can be confused with that of Ocrepeira species.
Unrecognizable. Neoscona nigrovariata Mello-Leitiio, 1941:258.
The species north of the Isthmus of Tehuantepec are: Neoscona arabesca, N. domiciliorum, N. crucifers (=N. hentzii), N. nautica, N. oaxacensis, N. orizabensis, N. pratensis, N. utahana. Misplaced by Berman and Levi (1971) was N. redempta (Gertsch and Mulaik) which is Ocrepeira redempta (Levi, in press).
The Central American species are N. arabesca, N. nautica, and N. oaxacensis.
The West Indian species are N. moreli, N. nautica, and N. mar- canoi n. sp., with only N. marcanoi native, the other two introduced.
The South American species are N. oaxacensis and the intro- duced N. moreli and N. nautica. The distinguishing characters of these species are the dorsal pattern of the abdomen, the shape of the epigynum and the conductor (C in Figs. 6-8, 16), the terminal apophysis (A), and the embolus lamella (L) of the palpus.

228 Psyche [Vol. 99
Note: This is probably a native species, not introduced. Males and females were collected together. Illustrations were made from holotype and paratype.
Diagnosis. The female differs from that of N. moreli by a shorter abdomen, marked dorsally with light spots (Fig. 4), and by a shorter, wider epigynum (Fig. 1) which is wider at the lateral lobes than at its base (Fig. 2). The male differs by having the con- ductor with a dark, sclerotized lobe (Fig. 7) and by the shape of the terminal apophysis (A) and embolus lamella (L) (Figs. 7, 8). The second tibia has a dense field of setae (Fig. 9). Paratype. DOMINICAN REPUBLIC: 1 km S Las Matas de Far- tan, 25 Aug. 1970, Q (B. Patterson, MCZ). Neoscona nautica (L. Koch)

Neoscona arabesca: - Berman and Levi, 1971: 474, Figs. 14 to 35, Q, 0.
Diagnosis. This is the smallest and commonest North American species. The female has an egg-shaped abdomen, with characteris- tic pairs of diagonal marks (Fig. 15 and 1971, figs. 34, 35). The male has the edge of the embolus lamella (L) and terminal apoph- ysis (A) almost parallel and the conductor (C) relatively straight (Fig. 16). The male left second tibia (Fig. 17) lacks the field of short setae present in some other Neoscona species. Note. The illustrations of the female were made from an indi- vidual from Costa Rica, that of the male palpus from a specimen from Talapa, Mexico, the patella and tibia from a male from Cuba. Natural History. Specimens came from a sorghum field in Hon- duras; others were found in meadows and open areas. Distribution. Common from southern Canada and the United States south to Costa Rica, Bahamas, Cuba, Hispaniola, and Jamaica.

The conductor of the male palpus is relatively straight and the terminal apophysis has a concave edge (Fig. 20). The second tibia of the male has a dense field of short setae (Fig. 21).
Note. Figure 18 was made from a female from Depto. Valle, Colombia, Fig. 19 from Puerto Rico and Fig. 20 from a male from Depto. Meta, Colombia, Fig. 21 from a male from Cuba. Natural History. Specimens were collected in Puerto Rican mountains, in an open abandoned parking lot, in high grasses and herbacious vegetation, and in a soybean field in Palmira, Valle, Colombia.
Distribution. Widespread in Subsaharan Africa? Madagascar, Reunion, Mauritius and Seychelles, West Indies, and with scat- tered records in South America (Map). I assume the species is an introduction to the Americas, judging by the limited American, and widespread African distribution.

Description. Male holotype. Carapace brown, with eyes on black spots, and with branched darker brown mark. Sternum brown with large central black spot. Legs brown. Abdomen in poor condi- tion, with black and white patches (Fig. 271, venter black with a pair of white marks. Posterior median and lateral eyes 0.8 diameter of anterior medians. Anterior median eyes 1.3 diameters apart, 2 from laterals. Posterior median eyes slightly more than 1 diameter apart, slightly more than 2 from laterals. Ocular quadrangle as long as wide behind, wider in front. No hook on first coxa. The second tibia short and not modified. Articular membrane of first femur and patella extending on venter of femur to one quarter its length. Abdomen longer than wide with anterior humps (Fig. 27). Palpus with one patellar seta. Total length 4.0 mm. Carapace 2.1 mm long, 1.7 wide. First femur 2.2 mm, patella and tibia 2.6, metatar- sus 1.4, tarsus 0.7. Second patella and tibia 2.0 mm, third 1.4, fourth 2.1.
The illustrations were made in 1971 from the holotype. Diagnosis. The male is probably close to Alpaida almada Levi, but differs by the branched pattern on the carapace, by the marks

Aculepeira aculifera: - Levi 1991a: 304, figs. 566-577. Synonymy. The male was temporarily placed in Metazygia because of the median apophysis lacking spines and flagella (Fig. 28) and the palpal patella having only one macroseta, Reexamining the specimens when revising Metazygia I noticed that the posterior median eyes face forward and to the sides as in Aculepeira species and very differently from those of Metazygia. The female is Aculepeira aculifera: the female epigynum is similar to that illus- trated by figures 574 and 575 (Levi, 1991a). The male and female seem to belong together: it appears that in the male syntype one palpal patellar seta of the two is broken off and that both flagella of both left and right median apophyses are broken. The name aculifera can be kept for the species since page priority does not apply -
Description. Male syntype of Epeira helveola. Color as in female. Dorsum of abdomen with similar folium, venter with a pair of white spots near spinnerets, Posterior median eyes same diame- ter as anterior medians, laterals 0.8 diameter. Anterior median eyes 1.1 diameters apart. Posterior median eyes 1.1 diameters apart. Ocular quadrangle slightly narrower behind than in front. Height of clypeus equals one diameter of anterior median eye. Endite with tooth, palpal femur with facing tubercle. Palpal patella with one macroseta (second may be broken off). First coxa with minute hook. Second tibia thicker than first. Abdomen ovoid. Total length 4.5 mm. Carapace 2.5 mm long, 2.0 wide, behind lateral eyes 0.9 wide. First femur 2.9 mm, patella and tibia 3.6, metatarsus 2.5, tar- sus 0.9. Second patella and tibia 3.0 mm, third 1.4, fourth 2.3

Diagnosis. The male has a much smaller conductor (behind prong in Fig. 28) than that of A, packardi (Thorell) (Levi, 1977, figs. 159-160) and differently shaped median apophysis with a lobe below the "fish-tail" (Fig. 28) than that of A. packardi or A. callaria (Levi 199 1 a, fig. 565).
The revision of the Neotropical Araneus (Levi, 199 1 a) unfortu- nately had several misprints. Most important is a misprint of the key on p. 186.

On p. 298 (Levi, 1991a), second column, couplet 4(3), read vit- tala not lisei.
The holotype of Aculepeira machu (p. 302) is now in the MUSM, not USNM; the same for the holotype of Wagneriana sil- vae (Levi, 1991b, p. 409).

from Colatina, Espirito Santo, Brazil in MNRJ is not lost; it was examined and illustrated earlier as Alpaida scriba (Mello-Leitgo). Neosconu rnarcanoi n. sp. is described from Hispaniola. There are new illustrations for the 4 Neotropical species and a new key and records for the South American species of Neosconu. Alpaida tullgreni from Venezuela and the male Aculepeira aculifera are illustrated. There is a correction for the key to Neotropical Ara- neus species.
