Name

Selenops morosus Banks, 1898Wikispecies linkPensoft Profile

  • Selenops morosus Banks 1898[1]: 267, pl. 16, Fig. 16 (♂, ♀, examined).
  • Selenops morosus F.O. Pickard-Cambridge 1900[2]: 118 (no Figs).
  • Selenops morosus Muma 1953[3]: 41, Figs 69–70 (♂, ♀).

Type material

Lectotype male (designated here): Tepic, México, X-XI, Eisen and Vaslit (MCZ, examined). Female syntype has been lost or destroyed, and thus the female is unknown.

Other material examined

MÉXICO: Sonora: 2 miles south of Imuris on Mex 15, 10.IV.1965, W. Shear, 1♂ (AMNH).

Diagnosis

Males can be distinguished by the RTA with two small pointed, angular projections, and the MA, which has a large triangular base and is directed somewhat ventrally (Figs 41–42).

Remarks

Banks (1898)[1] illustrated a male and a female specimen and noted that ‘several specimens' had been collected. Muma (1953)[3] reported that the female type was lost or destroyed, but that females of Selenops abyssus may go with males of Selenops morosus, as the illustration of the epigynum by Banks (1898)[1] is similar to that of Selenops abyssus. Muma also mentions two males and one young female from Tepic at the MCZ, but only a single male was located. An additional specimen from much further north (Sonora) was found in the AMNH. The epigynum illustrated by Banks (1898)[1] looks nothing like that of Selenops abyssus, and I conclude that Selenops abyssus and Selenops morosus are distinct species. Banks (1898)[1] did indeed have the female of Selenops morosus. The geographic range of Selenops abyssus encompasses that of several species known from only one sex, as does Selenops morosus. More collecting from this region and independent data, such as that of molecular or behavioral data, will be needed to determine which males and females belong together. The male specimen is also in poor condition and the description may not reflect well the coloration and markings of this species.

Description

Abdomen:without terminal setal tufts. Pedipalp:Fm, spination d 0–1–4;cymbium oval in ventral view, pointed distally, slightly angled posterolaterally; conductor large, attached to bulb on short straight stalk anteromedially, directed laterally, but not extending beyond the edge of cymbium, left side connecting to bulb and forming a circular area between the two conductor connections; embolus long, slender, curved, tapering midway, beginning at 6 o'clock, terminating at 12 o'clock; MA arising at 2 o'clock, directed lateroventrally, with stout triangular base, tapered to a distally hooked process; RTA small, barely reaching cymbium in ventral view, with two processes, in lateral view, the ventral process with a distally pointed process and a process that points downward, the lateral process with a distally pointed structure arising from a quadrangular process (Figs 41–42).

Natural history

Nothing is known of this species' natural history, but based on collection locality data, it seems to span aridland and tropical thornscrub habitats.

Distribution

Known from northwestern México and has an apparently broad distribution from northern Sonora to Nayarit (Map 5).
