Name

Psammoecus trimaculatus Motschulsky, 1858Wikispecies linkPensoft Profile

  • Psammaechus [sic.] trimaculatus Motschulsky, 1858: Etud. Ent. 7: 45. Type locality: Sri Lanka; Type deposition: Zoological Museum, Moscow Lomonosov. (referring to Hetschko (1930)[1])

Diagnosis

This species is closely similar to Psammoecus triguttatus and Psammoecus labyrinthicus sp. n. but it can be distinguished from the former by the larger basal parameres and the broader distance between the posterior margin of the phallobase and the deepest point of incision of the anterior margin of the phallobase, and from the latter by the larger bases of parameres and the wider protuberances on the inner margins of the branches of the anterior phallobase. The rows of punctures on the elytra of Psammoecus trimaculatus (Fig. 5E) are comparatively narrower than in these two closely similar species. However, their external characters, especially their coloration, are variable. These features may cause misidentification.

Description

Body length. 2.32–2.96 mm (n=38).
9th abdominal sternite (Fig. 13G). Strut Y-shaped, elongate, cut at anterior 3/8, diverging in posterior 1/5, branches relatively wide, narrowed gradually toward apex, ends of each branch curved inward. Lateral sclerites elongate, membranous.
Aedeagus (Fig. 13H, I). Parameres hatchet-shaped, inner margin around bases pointed, punctuated sparsely on stick-shaped portions, densely on anterior portions, a long seta at each apex, numerous short setae on stick-shaped portions and around inner margins of anterior parts. Posterior margin of phallobase rounded, phallobase roundly hollowed, its anterior branches markedly protruding inward. Penis gradually narrowed toward apex, posterior 1/9 flattened, punctuated sparsely on posterior 1/9.

Distribution

JAPAN: Hokkaido, Honshu, Shikoku, Kyushu, Amami-Ôshima, Okinawa, and Iriomote Islands. (Madagascar recorded by Karner (2012)[14]; Nepal, India and Bhutan recorded by Pal (1980).)

Remarks

This species was redescribed by Pal (1980) with a description of the larva. It is distributed worldwide except for Europe and North America and common at least in Japan and India (Hirano 2009[12]; Karner 2012[14]; Pal 1980).
Hirano (2009)[12] and Hirano (2010)[13] illustrated this species as Psammoecus triguttatus and suggested that the distribution of Psammoecus trimaculatus in Japan is doubtful. In this paper, it is regarded as Psammoecus trimaculatus on the basis of comparison of the male genital structure of the species illustrated by Pal (1985)[8].
Pal (1985)[8] gave as the distribution of this species Madagascar, Sri Lanka, Nepal, India, Malaysia, Burma, New Guinea, Australia and Japan, synonymizing the following species with Psammoecus trimaculatus: Telephanus cruciger Waterhouse, 1876 and Psammoecus cephalotes Grouvelle, 1919 from New Guinea, Cucujus incommodus Walker, 1859 from Sri Lanka and Psammoecus ypsilon Blackburn, 1903 from Australia (Walker 1859[15]; Waterhouse 1876[2]; Blackburn 1903[16]; Grouvelle 1919[17]). In addition, Thomas and Yamamoto (2007)[18] recorded this species from Brazil. However, in view of the evidence that at least two other closely similar species have been confused with this species, past records of this species should be reexamined. The specimen figured by Thomas and Yamamoto (2007)[18] seems to be another species. In this paper, records of this species from outside Japan are recognised from label data described by Pal (1980) and Karner (2012)[14], on the basis that they examined the male genital structure.
