Name

Psammoecus fasciatus Reitter, 1874Wikispecies linkPensoft Profile

  • Psamoecus [sic.] fasciatus Reitter, 1874: 525. Type locality: Japan; Type deposition: the Natural History Museum, London; Type examined. (misspelling)
  • Psammoecus fasciatus: Hetschko 1930[1]: 82.

Diagnosis

This species is closely similar to Psammoecus hiranoi. It can be distinguished by the longer parameres, the shallower incision of the phallobase on the anterior 1/4 and the shorter teeth on the lateral margins of the pronotum.

Description

Body length. 2.75–3.50 mm (n=49).
Coloration (Fig. 2D). Head and pronotum yellowish-brown to reddish-brown. Elytra with a variable horizontal dark band at middle, this band in lighter color specimens thinner towards elytral suture, lateral margins, apical portion and posterior elytral suture dark. Antennae brown or reddish-brown basally, 7th and 8th antennomeres darker, 9th and 10th almost black, 11th (apex) lighter than basal ones. Antennae of some specimens almost unicolorous.
Head (Fig. 11A, B, C). Broad, HW/HL 1.40–2.08; IE/HL 0.94–1.38. Temples enlarged behind eyes, narrowed gradually toward posterior margin. Eyes large, slightly prominent. Ventral surface with rough irregular punctuation, sparser punctuation on dorsal surface. Antennae 1.38–1.57 mm, 2nd antennomere short; covered with thick medium length pubescence and some long erect pubescence on each antennomere; approximate ratio of lectotype as follows: 2.5: 1.0: 1.3: 1.3: 1.3: 1.3: 1.3: 1.3: 1.3: 1.2: 1.8 (Fig. 11A).
Pronotum (Fig. 11B, C). Broad, PW/PL 0.69–1.52. Punctuation on dorsal surface very dense, but no punctures around posterior margin, punctuation on ventral surface sparser than dorsal surface, some of them in rows especially on posterior half. Pubescence composed of frequent short setae on dorsal surface and a long seta on each tooth on lateral margins and at anterior and posterior angles. Each anterior angle with a distinct group of a few very small teeth, each lateral margin with four teeth; tooth I comparatively small, teeth II, III and IV almost the same moderate size, each posterior angle with a comparatively small tooth.
Elytra (Fig. 11E). Elongate-oval, EW/BL 0.41–0.47. Punctures wider than interstices. Pubescence composed of semi-erect medium length setae and some long erect setae in a row around lateral margins, longer toward anterior portion.
9th abdominal sternite (Fig. 14M). Strut cut at around half, diverging widely around the posterior base, ends of each branch curved inwards. Lateral sclerites triangular, flat.
Aedeagus (Figs 14N and O). Parameres simple stick-shaped, elongate, slightly curved inwards, punctuated sparsely except base, a few semi-long setae around apical portion. Phallobase diverging gradually around anterior 1/4, a little bulging along inner margins of each branch, lateral margins broadening. Penis also elongate, punctuated on posterior 1/6, more densely on ventral portion, especially densely on apical portion.

Biological notes

The first author (Yoshida) collected this species from various kinds of dead leaves from evergreen trees, deciduous trees and bamboo.

Remarks

The syntypes of this species consist of three specimens: two of them belong to this species, but the remaining one represents Psammoecus trimaculatus or Psammoecus triguttatus. We designate a male specimen as lectotype, and a female specimen as paralectotype. The type specimens were collected from Mt. Maya-san, Kobe City, Hyogo.
