Geometric recovery by humidification of densified wood of eight Mexican species

Mexican species of three pimpline genera, Apechthis Förster (one species), Itoplectis Förster (six species) and Pimpla Fabricius (20 species, including one unidentified taxon), are reviewed. Four species of Pimpla are described as new to science: P. chamela sp. nov., P. oaxacana sp. nov., P. tequila sp. nov. and P. xalapana sp. nov. Pimpla thoracica Morley, 1914 is found to be a junior synonym of P. ellopiae Harrington, 1892 (syn. nov.). Apechthis zapoteca (Cresson) is recorded for the first time from Venezuela, Pimpla dimidiata (Townes) from Mexico, P. caeruleata Cresson, P. croceiventris (Cresson), P. sanguinipes Cresson and P. sumichrasti Cresson from Honduras, P. ichneumoniformis Cresson and P. viridescens Morley from Guatemala and Honduras, and P. punicipes Cresson from Panama. The South American species Pimpla caerulea Brullé and the Nearctic species P. pedalis Cresson are excluded from the Mexican fauna. Male of Itoplectis mexicana and female of Pimpla dimidiata are recorded for the first time. Identification keys to the species of Itoplectis and Pimpla occurring in Mexico are provided.

Four new Mexican Parajapyx species are described: P. silvestrii sp. nov. differs from P. adisi Pagés by the presence of one ma macroseta on mesoscutum, metascutum and abdominal scutum I; P. pagesi sp. nov. differs from P. grassianus Silvestri in the arrangement and number of macrosetae on all abdominal scuta; P. brunocondei sp. nov. is characterized by the unique feature of 50 glandular setae on the subcoxal organs and femur with one macroseta; P. yunyanorum sp. nov. differs from P. reymi Pagés by having some reduced macrosetae on the mesoscutum and metascutum and one lp macroseta lacking on abdominal II to VII scuta. A redescription of P. isabellae aztecus Silvestri, 1948 is presented including additional characters not previously reported, such as complete body chaetotaxy and descriptions of leg III, antennae and cercus. An identification key is presented for Mexican species of Parajapyx.

Mexican Species

On September 9th, 2010, we found an individual of Lithobates neovolcanicus in a pond near to a disturbed pine forest from Mezcala de la Asunción, Poncitlán, Jalisco. The specimen presented two different deformities in its left forelimb and right hindlimb, polymelia and ectromelia, respectively. This is the first record of limb malformations in this endemic Mexican species.

Mexican Species

The seed of the Mexican species, Casimiroa edulis Llave et Lexarza is valued for medicinal purposes. We have studied its anatomy in different stages of development from ovule to mature seed. We applied general staining with safranin and fast green and specific staining for the detection of starch, lipids, lignin, polyphenols, and proteins. Embryo and seed development was also evaluated on the basis of volume. The ovule is sessile, bitegmic, crassinucellate, hemianatropous, with a nucellar curvature of 30-40º and a large hilum. The seed develops a large pachychalaza that covers approximately 70% of the surface. The testa is thin, nonlignified and tanniferous. The mature embryo occupies about 90% of the whole volume of the seed and contains lysigenous oil glands, starch grains and protein bodies. The radicle is not directed exactly at the micropyle. lt is located in the dorsal micropylar third of the seed. Casimiroa edulis had been described as lacking endosperm, but in reality the mature seed has a small amount of endosperm under the pachychalaza.
