Wing Folding

The wing folding mechanism was investigated after a detailed study of the wing base morphology had been made (Sharplin, Canad. Ent. 95: 1024; 1121). Living moths were observed with a binocular microscope equipped with a micrometer eyepiece.The first and second axillary sclerites do not move anteroposteriorly; only the distal half of the wing base is involved in wing folding. The folding muscle originates on the pleural ridge and inserts on the third axillary sclerite. The movement of the third axillary is communicated to the bases of the anterior veins through the median plates. The radial plate rotates around the ventral second axillary sclerite which lies underneath the radial bridge at point p, (Fig. 1). Bending cuticle allows the radial bridge to buckle when the wing is folded. The first median plate ( Ml ) rotates about its articulation ( f ) with the dorsal second axillary sclerite. The distal median plate (M2) passes underneath the second cubitus and is fused to the radius. This connection to the radius restricts the backward movement of the second median plate so that point e instead of following the wider arc eg of a circle with its centre at f, must follow the arc cegd drawn about pivot p. The median plates are bent upwards during wing folding and their effective length is shortened so that they can follow the shallow arc epg. When point e is in position g the posterior margin of the median plates is straight, although the anterior margin remains arched causing the median plates to be buckled, (Fig. 2).

We hereby revise the Jamaicensis group of species of Trachymyrmex (Myrmicinae: Attini), as the third part of our taxonomic revisionary studies on this fungus-growing ant genus. The species group we deal with here includes six taxa that share exclusively the antennal scrobes always reaching the posterior margin of the head and ending as two separate projections arising from the preocular and frontal carinae, giving the scrobe posterior region an “opened” appearance and an angular profile to the posterolateral corners, in frontal view. The Jamaicensis group is composed of Trachymyrmex atlanticus n. sp. (eastern Brazil), Trachymyrmex haytianus Wheeler & Mann, 1914 n. st. (Haiti, Jamaica), Trachymyrmex isthmicus Santschi, 1931 (Colombia, Ecuador, Panama), Trachymyrmex ixyodus n. sp. (northern Brazil, Suriname), Trachymyrmex jamaicensis (André, 1893) (Caribbean islands and southern USA), its synonyms (Trachymyrmex sharpii Forel, 1893; Trachymyrmex maritimus Wheeler, 1905 n. syn.; Trachymyrmex jamaicensis var. frontalis Santschi, 1925 n. syn., and Trachymyrmex jamaicensis cubaensis Wheeler, 1937 n. syn.), and Trachymyrmex zeteki Weber, 1940 (Colombia, Costa Rica, Ecuador, Panama). Trachymyrmex jamaicensis antiguensis Weber, 1938 is excluded from the Jamaicensis species group because it belongs to the Trachymyrmex Urichi species group. The only known Trachymyrmex fossil, T. primaevus Baroni Urbani, 1980, from the Dominican amber, does not belong to the Jamaicensis species group, as hypothesized earlier.

Precise Shape

Literature on the anatomy of the human vertebral column characterizes the shape of the lumbar vertebral canal as triangular. The purpose of the present study was to determine the precise shape of the lumbar vertebral canal. Ten lumbar vertebral columns of adult male cadavers were dissected. Two transverse sections were performed in the third lumbar vertebra. One section was performed at the level of the lower border of the ligamenta flava, and the other section was performed at the level of the pedicles. The shape of the lumbar vertebral canal at the level of the pedicles tends to be oval or circular, whereas the shape of the lumbar vertebral canal at the level of the lower border of the ligamenta flava is triangular. Thus, the shape of the human lumbar vertebral canal is not exclusively triangular, as reported in the literature. It is related to the level of the transversal section performed on the lumbar vertebra. This finding should be taken into consideration among factors involved in the spread of solutions introduced into the epidural space.

Long-tailed Nesokia, Nesokia bunnii, is a large rat restricted to the Mesopotamian marshes in Basra Province in southern Iraq. The species is known from five museum vouchers collected between March 1974 and January 1977. The type and the paratype, deposited in the Natural History Research Centre and Museum, University of Baghdad, Iraq, were destroyed during War on Iraq in 2003. By studying morphological details on three museum specimens in the Senckenberg Institution, Frankfurt a. M., Germany, we show that N. bunnii is unique among the Bandicoot rats (Nesokia and Bandicota) in having (1) rufous dorsal pelage, (2) facial mask of rufous, dark brown, grey and whitish areas, (3) whitish belly which is clearly demarcated along flanks, (4) ventral hairs white to bases, (5) woolly underfur, (6) long front claws, and (7) large tail annulation. Similar to N. indica, but in contrast to Bandicota, N. bunnii displays short incisive foramina, posterior margin of hard palate which terminates at the level of the third molar, and robust, hypsodont and laminate molars which lack posterior cingula. To objectively define the taxon we designate a neotype, which was collected at Saraifa, 30 km north of Qurna, Iraq. Our study highlights the importance of museum collections in documenting biodiversity and the indifference of decision makers and international institutions regarding their safe future.

A New Species

A new palaemonid shrimp genus, Opaepupu gen. nov., is established to accommodate a new species of bivalve-associated shrimp, Opaepupu huna sp. nov. from Hawaii. A single mated pair, the female holotype and the male allotype, were found inside the trapezid bivalve Trapezium oblongum (Linnaeus, 1758) at a depth of 14 m in Kâne’ohe Bay, Hawai’i. The new genus is characterised by the rostrum being proximally broad, distally pointed, mid-dorsally carinate, and non-dentate; the anterolateral margin of the carapace without supraorbital, hepatic or epigastric teeth, but with a strong sharp antennal tooth; the sixth pleonite posteriorly unarmed; the telson medially depressed, with the dorsal surface armed with two pairs of submarginal cuspidate setae and with the posterior margin armed with two pairs of spiniform setae; the distolateral angle of the first article of the antennular peduncle without a sharp tooth; the mandible without a palp; the maxillular palp furnished with one long stiff seta dorsal to a small tooth-like extension; the first maxilliped without a palp; the third maxilliped not being operculate; the second pereiopods moderately robust, relatively slender, subequal, subsymmetrical, with simple teeth on the cutting edges of the fingers; the ambulatory pereiopods being slender, each ending in an elongate biunguiculate dactylus; and the uropodal exopod with a faint diaeresis and greatly reduced distolateral spiniform seta. The phylogenetic position of Opaepupu gen. nov. remains unclear, although it does not appear to be closely related to other bivalve-associated palaemonid genera.

The pelagic processid, Processa pippinae Wicksten & Méndez, 1985, has been reported previously as an endemic species in the northern Gulf of California, Mexico. Additional material collected accidentally in a benthic sledge and with a mid-water micronecton net is reported, including a series of small-sized specimens (CL 2.2 mm). The shape of the laterally compressed rostrum of this species varies considerably with size and among adult specimens. Based on several morphological characteristics of P. pippinae, a new genus, Maryprocessa, is proposed. Several unique characteristics separate Maryprocessa new genus from the other five genera of Processidae, including the laterally compressed rostrum overreaching the cornea, unique among the Processidae, the extraordinary long antennal and antennular flagella, the posterior lobe on the dorsal margin of the third abdominal somite, and the long, acute pair of spines on the posterior margin of the sixth abdominal somite.

A New Species

The new anchovy Encrasicholina sigma n. sp. is described on the basis of 20 specimens collected from Sulawesi, Indonesia. Although the new species can be distinguished from all other congeners except for Encrasicholina pseudoheteroloba (Hardenberg 1933) by having a long upper jaw reaching to posterior margin of preopercle, dorsal and anal fins with two unbranched rays, an exposed bony urohyal, and spine-like scutes on the abdomen, E. sigma is distinguished from E. pseudoheteroloba by lower total gill-raker counts on the first, second, third, and fourth gill arches, and on the posterior face of the third gill arch (37–42, 31–35, 18–23, 16–20, and 4–7, respectively vs. 45–55, 34–45, 22–29, 19–25, and 4–9 in E. pseudoheteroloba) and a longer head (25.2–27.0% of SL vs. 22.8–27.5%) and shorter anal-fin base (12.9–14.8% of SL vs. 13.8–18.7%).
