Neaenus hystricosus
status

sp. nov.

Neaenus hystricosus sp. nov.

Etymology. hystricosus (adj.), thorny.

Diagnosis. Male theca with marginal spines surrounding apical half of shaft in caudal aspect ( Fig. 47 View FIGURES 46 – 54 C).

Description. Head and dorsum black, venter and tegmina dark brown, usually varied with orange on base of clavus (as in type, Fig. 10 View FIGURES 10 – 11 B) or pale brown on base of clavus and/or costa. Male pregenital tergite lobes slender, curved ventrad, sternite with spiny lobe just before genital capsule ( Fig. 47 View FIGURES 46 – 54 A); subgenital plates with prominent lobe on dorsal side of basal half, as in Tropidorhinella inflata (Jacobi) ; styles broadly furcate at tip, as in genotype; phallobase large, with thick upper lobe; theca strongly curved on basal half, apical third with triangular lobes directed cephalad ( Fig. 47 View FIGURES 46 – 54 B). Length: male 5.7–6.4 [holotype] mm, female 6.9 mm.

Types. Holotype male, MEXICO: Sin. ─Sta. Lucia, 4 Aug. 1964 (L.A. Kelton). Paraptypes: 2 males, same data as holotype ; 1 male, Sin. ─ Portrerillos , 15 mi W El Palmito, 5000' [ASL], 4 Aug. 1964 (J.F. McAlpine) ; 1 female, same locality, 9 Aug. 1964 (L.A. Kelton). All types No. 24222 in CNCI .

Remarks. The spiny thecal tip and lobate subgenital plates are characteristic of Tropidorhinella Schmidt , but the styles, pregenital tergal lobes and shape of the pronotum show that these genera are not related. This species is 3% divergent from the lineage to which belongs an undescribed female (also from Sinaloa in Mexico).

Neaenus natrix sp. nov.

Etymology. natrix (noun in apposition), water-snake.

Diagnosis. Styles broad at midlength, constricted on apical third and serpentine, hooked ventrad at tip ( Fig. 46 View FIGURES 46 – 54 A).

Description. Male black with eyes brown to crimson, two elongate ivory spots on costa (often connected into a wavy line, as in the type) and with coxae plus hind tibia and tarsi pale brown; female colored as in N. hystricosus but with reddish eyes and wing markings as in male. Antenna with 10 pits clustered at tip of postpedicel and short, peglike basiconic sensillum ( Fig. 21 View FIGURES 20 – 23 B), Male pregenital tergite lobes slender, curved upwards, longer than those in N. varius and not spatulate at tips; subgenital plates tapered, directed caudad; phallobase short, with slender dorsal process ( Fig. 46 View FIGURES 46 – 54 B); theca evenly curved cephalad, laterally compressed, armed only with low spiculate lobes near midlength, most clearly visible in caudal aspect ( Fig. 46 View FIGURES 46 – 54 C). Length: male 5.2 [holotype] – 5.6 mm, female 6.2–6.5 mm.

Types. Holotype male, MEXICO: Chis.─ Zontehuitz , nr. S[an] Crist [obal], 9500', 27 May 1969 (W.R.M. Mason) . Paratypes: 1 male, 4 females, same data as holotype ; 1 female, Mt. Tzantehuit , 3000m, 17 May 1969 (J.M. Campbell). All types No. 24223 in CNCI .

Remarks. The short basiconic sensillum and serpentine style tip without setae are shared with the following new subgenus, from which lineage this species is only 2% divergent.
