Demoulinia insularis Lugo-Ortiz & McCafferty 1998
No full textDemoulinia insularis Lugo-Ortiz & McCafferty 1998 (Figs 6–7, 24–25, 38, 44, 57) Demoulinia insularis Lugo-Ortiz & McCafferty 1998: 360 (larva). Demoulinia assimilis Gattolliat 2003: 2 (larva), syn. n. Material. The holotype of D. insularis is deposited in Purdue Entomological Research Collection, West Lafayette, Indiana, USA (Lugo-Ortiz & McCafferty 1998: 357) and is a mature female larva ready to moult to subimago; certain parts of it are slide-mounted (Lugo-Ortiz & McCafferty 1998: 360), and the remaining parts are preserved in alcohol; Luke Jacobus kindly reexamined this specimen and made pictures (Figs 6–7, 24–25, 38, 44). The holotype and the paratypes of D. assimilis are deposited in the Museum of Zoology, Lausanne, Switzerland (Gattolliat 2003: 2); Jean-Luc Gattolliat kindly reexamined certain details, prepared an additional slide of mature male larva and made pictures (Fig. 57). Synonymy of D. insularis and D. assimilis. The original description of D. insularis was based on a single larva. The original description of D. assimilis was based on 21 larvae (Gattolliat 2003). As the differences between D. assimilis and D. insularis, Gattolliat (2003) reported three characters: the setation of the dorsal surface of the labrum, the shape of the lingua and the number of the segments of the maxillary palp. Labral setation of D. assimilis was described as «subapical row of about 11 long stout setae subparallel to the distal margin, a few long fine setae scattered over surface» (Gattolliat 2003: 2, fig. 1), while labral setation of D. insularis was described as «numerous long, fine, simple setae scattered over surface» (Lugo-Ortiz & McCafferty 1998: 360, fig. 11). The South African species D. crassi demonstrates individual variability of this character: in some individuals long setae are evenly scattered over surface (left side of Fig. 11), in others they form a more or less distinct subapical row (Fig. 9); this fact allows the assumption that the Malagasy species can have the same individual variability. The hypopharynx of D. assimilis was described as having «a broad trilobate superlingua, covered only with minute setae; lingua weakly developed laterally, apically with long thin setae» (Gattolliat 2003: 2, fig. 2); here the term «superlingua» is erroneously applied to hypopharynx (= lingua), and the term «lingua» is erroneously applied to superlingua. The hypopharynx of D. insularis was not characterized, and only figured in a resolution which does not show its setation (Lugo-Ortiz & McCafferty 1998: fig. 12). The holotype of D. insularis is a larva ready to molt to subimago, so its mouth parts are represented by empty cuticle; in such a condition the hypopharynx, which has a very thin cuticle, is crumpled: left lobe of the hypopharynx (= lingua) is compressed, but the right lobe retains its shape (Fig. 25); it shape does not differ from that of D. assimilis (Gattolliat 2003: fig. 2) and D. crassi (Fig. 23). The maxillary palp of D. assimilis was described as «3-segmented» (Gattolliat 2003: 4, fig. 5), while the maxillary palp of D. insularis was described as «two segmented» (Lugo-Ortiz & McCafferty 1998: 360, fig. 15). However, the holotype of D. insularis (which is the only specimen of the type series) has one maxillary palp broken; another palp is preserved, mounted on a slide and has a clearly expressed third segment (Fig. 24) whose shape is the same as in D. assimilis (Gattolliat 2003: fig. 5) and in D. crassi (Figs 21). Thus, not one of the three reported characters allows D. assimilis to be distinguished from D. insularis. A new synonymy is proposed here: Demoulinia insularis Lugo-Ortiz & McCafferty 1998 (= Demoulinia assimilis Gattolliat 2003, syn. n.).Published as part of Kluge, Nikita J., 2020, Demoulinia Gillies 1990 and two unnamed genera of the plesiomorphon Protopatellata (Ephemeroptera, Baetidae) from South Africa, pp. 438-464 in Zootaxa 4820 (3) on pages 445-446, DOI: 10.11646/zootaxa.4820.3.2, http://zenodo.org/record/439801

This species is named in honor of the JMW's late grandmother, Dorothy Webb. Diagnosis and discussion. Larvae of N. dorothae are identified by the presence of two rows of denticles on the tarsal claws (Fig. 6c). Nixe dorothae and N. perfida are superficially similar and occur in the same geographic region, but, in addition to the second row of denticles, N. dorothae larvae usually have two pairs of pale sublateral spots on each abdominal tergum (Fig. 1) whereas N. perfida larvae have only a single pair. Nixe flowersi is also known from southern Indiana but differs from N. dorothae by having a single row of denticles on the tarsal claws, clavate robust setae on the femora (similar to Fig. 18), and much more extensive pale areas on the abdominal terga (Fig. 19, McCafferty 1977: Fig. 3, as Heptagenia perisimplex McDunnough, 1929) The reddish brown markings on the abdominal sterna can vary within populations from completely absent to well developed and should not be considered diagnostic. Adult males are differentiated from North American congeners by the combination of the reddish brown dorsal color pattern (Fig. 7) and penes with median spines on the apical sclerites (Fig. 10). The only other North American species with spines on the apical sclerites is N. flowersi, but its abdomen is cream colored rather than reddish brown. Nixe horrida, N. lucidipennis, N. perfida and N. rusticalis all have reddish brown abdominal terga, but the penes lack median spines on the apical sclerites. Nixe dorothae were most often collected from small, intermittent or spring-fed streams in southern Indiana. Material examined.

Head: Head capsule brown with pale stripe from lateral ocelli to lateral margin and pale spot anterior of median ocellus; anterior margin slightly thickened and with row of fine setae (Fig. 2). Labrum (Fig. 3) 5X wider than long, dorsal surface with dense brush of highly fimbriate setae, ventral surface with anterior portion with dense, fine setae, and posterior portion with somewhat stouter setae. Mandibles as in Figs. 4 and 5. Hypopharynx (Fig. 6) expanded distolaterally, posterolateral corners rounded. Maxillae (Fig. 7) ventrally with scattered simple setae; apical margin with 20 comb setae and two simple setae; distal dentisetae branched near base; palps with numerous fine setae on first segment, second and third segments mostly fused, with dense brush of setae apically and with terminal spine. Labium as in Fig. 8; glossae subquadrate with numerous robust, bipectinate setae ventrally (Fig. 13); paraglossae ventrally with numerous robust, bipectinate setae apically, and dorsally with numerous long, fine setae. Thorax: Forelegs yellowish brown; forefemora with regular row of long setae dorsally, anterior face with paddle-shaped setae and small spines, ventral margin with robust pointed setae; foretibae with row of long, fine setae and 22 long, clavate robust setae on lateral ridge, posterior margin with row of short, fine setae, anterior margin with two robust setae, inner surface with four simple, robust setae and scattered fine setae; foretarsi with dense row of long fine setae and 5 long robust setae, entire surface with scattered fine setae; claws with three denticles. Midlegs similar to hindlegs but with fewer setae. Hindlegs (Fig. 9) yellowish brown; hindcoxae with subquadrate dorsal extension; hindfemora with regular row of long setae dorsally, anterior face with paddle-shaped setae (Fig. 14) and small spines, ventral margin with robust pointed setae; hindtibiae with row of long, fine setae and 15–20 long, clavate robust setae on lateral ridge, row of long, fine setae on posterior margin, 4–10 short, robust setae on anterior margin, inner surface with seven simple, short, robust setae and scattered short, fine setae; hindtarsi with dense row of long, fine setae and two long, robust setae, inner surface with three robust setae, entire surface covered with short, fine setae; claws with three denticles. Abdomen: Terga brown with slightly paler spots submedially and laterally, with median ridge present on 2–9 (Figs. 1, 12); sterna yellowish brown; small posterolateral spines present on segments 8 and 9; gills 1 with lamellae absent, fibrils well developed; gills 2–6 (Fig. 10) with lamellae long, slender, and curved, 12X longer than wide, outer margin with fringe of setae, fibrils well-developed; gills 7 (Fig. 11) with lamellae 3X longer than wide, anal margin with sharp serrations in basal half, outer margin with fringe of setae, fibrils absent. Caudal filaments brown, with small robust setae and short fine setae at articulations. Egg: Slightly oval, 13 µm long, 8.75 µm wide (Fig. 15). Chorion with numerous KCTs and small tubercles. KCTs more numerous at poles, those at one pole larger. Micropyle slightly oval and with rim slightly thickened (Fig. 16). Adult: Unknown. Etymology: The specific epithet is an allusion to the given name of the fictional character Darth Vader. Diagnosis and discussion: Because Darthus is monospecific, the specific diagnosis is the same as the generic diagnosis. Afronurus temburongensis Braasch and A. bruneiensis Braasch were recently described from Borneo from adult males (Braasch 2005). We do not believe either of these is the adult of D. vadorus because they are both light-colored species and the mature larva of D. vadorus has brown abdominal segments. We have seen a male of an undescribed species collected near the type locality of D. vardorus that may represent the adult of D. vadorus because it has brown abdominal segments and genitalia that are slightly different than those of other southeast Asian species of Afronurus. As this association cannot be verified at this time, we choose not to describe this specimen because much confusion has been created in the past by incorrectly associated larvae and adults, as discussed, for example, by Webb et al. (2006). Material examined: HOLOTYPE: 1 larva, Indonesia, E Kalimantan, Kayan-Mentarang Nature Reserve, Nggeng R, 2°52' N, 115°49' E, 30-March-1994, coll.
