Parandra (Parandra) antioquensis , new species

( Figs. 1 –7 and 9)

Description. Female ( Fig. 1 ). General coloration of the integument reddish-chestnut; head and mandibles dark chestnut; apical portion of the femora and tibial margins dark chestnut to black; elytral suture blackish.

Dorsal surface of the head densely covered by large punctures (larger at the region between the eyes and the occiput, and closer to each other at the latero-anterior area) (Fig. 2). Ocular carina wide and barely marked. Eyes small, protruding, and reniform. Genae laterally with moderately large punctures, some of them with a microscopic hair. Apex of the labrum rounded and blackish. Hypostomal carina narrow and low. Hypostomal area glabrous and with large punctures, which are abundant at the mentum and sparser near to the gula; anterior margin narrow and elevated laterally, almost flattened medially. Mentum with large, confluent punctures, and some moderately long hairs laterally, more abundant antero-laterally than medially (Fig. 3–4). The galea is long, almost reaching the apex of the third segment of the maxillary palps, with long and sparse pilosity. Teeth of the mandibular internal margin wide, protruding and joined at the basal portion (just separated near the apex); internal dorsal face with thick and scattered punctures, and hairs barely concentrated close to the internal margin; ventro-apical tooth protruding. Antennae 1.2 times the length of the prothorax medially; scape glabrous and with large, abundant punctures; pedicel glabrous; antennomeres III–X with long hairs at distal third (Fig. 5); antennomere XI with long and sparse hairs from the middle to the apex; antennomeres III–XI with a wide ventral sensorial area (as wide as 2/3 of its length), which is divided by a low carina (Fig. 6); dorsal-apical sensorial area of the antennomere XI elliptic and clearly defined (Fig. 7).

Prothorax transverse, wider near the head; curved laterally; pronotum with lateral margins upturned, mainly at apical two-thirds; anterior margin weakly sinuate; posterior angles obtuse; punctuation coarse and dense, mainly laterally. Metasternum with large, sparse punctures laterally, with fine and abundant punctures antero-medially; postero-medial area with punctures like those antero-medial ones, but more concentrated. Metepisternum with sparse punctures, similar to those at the lateral region of the metasternum. Elytra with large punctures, clearly larger than those of the head and pronotum, such punctuation is concentrated and well-defined except at the area around the scutellum, where punctures are shallower and more widely separated.

Abdominal sternites I–IV glabrous and with moderately abundant, large punctures; abdominal sternite V with punctures like those of the previous abdominal sternites at its basal third, with granules at the apical twothirds and hairs laterally and apically (which are longer near the apex). Tarsal paroniquium with one seta.

Dimensions in mm. Total length (excluding mandibles): 19,4; largest width of the prothorax: 4,7; pronotum length at the mid point: 3,4; humeral width: 4,8; elytral length: 11,4.

Etymology. This species is named after the Antioquia department, the locality where the type specimen was collected.

Type material. Holotype female, COLOMBIA, Departamento de Antioquia: Granada, III.1998, M. Londoño col. ( CEUA 12428).

The specimen was collected in the northern Central Andes of Colombia, in the municipality of Granada, Antioquia department. The label of the specimen only had written the municipality of Granada as it collection locality; nonetheless, we added some new information about this locality as follows: Granada is located at 06°08’48’’ N, 75°11’18’’ W in eastern Antioquia, most of the area is mountainous including temperate and cold habitats, the mean temperature being 16ºC ( IGAC 1996). Granada covers elevations between 700–2100 m; the annual precipitation ranges between 2000–4000 mm, and the region presents three Holdridge life zones: tropical moist forest, premontane rain forest, lower montane rain forest ( Cuartas et al. 1997).

Discussion. The new species was assigned to Parandra (Parandra) Latreille, 1804 . However it is very similar to members of the genus Acutandra Santos-Silva, 2002 . Generally, females of Acutandra have the anterior margin of the pronotum strongly sinuous; an alternative condition is seen in Parandra which exhibits such margin almost straight or weakly sinuous; nevertheless, exceptions to either condition could be found in both genera.

Santos-Silva (2002) defined the quantity of setae at the tarsal paroniquium in an attempt to separate the genera Acutandra from Parandra : Acutandra exhibits one or two setae, whereas Parandra has just a single seta. Likewise, the dorsal-apical sensorial area of the XI antennomere in P. antioquensis new species is clearly defined (Fig. 7); a character that occurs in all the known species of Parandra and can be present or not in Acutandra ( Santos-Silva 2002) . The main differences between those genera are present in the males (Santos- Silva 2002), where the apex of the labrum is truncated in Parandra and acute in Acutandra , and the mandibles are falciform in the former and subtriangular in the latter.

Parandra (Parandra) antioquensis new species is the first species of this subgenus occurring in South America ( Fig. 8). The remaining species occur in Central America and the Caribbean. This species largely looks like Parandra (Parandra) pinchoni Villiers, 1979 , from the islands of Martinique and Dominica, and differs from it by having a more slender body ( Fig. 1 ), by presenting a carina which splits the sensorial region of antennomeres III–IV, and by the shape of the posterior angles of the pronotum which are obtuse and barely protrude (Fig. 9). Parandra (P.) pinchoni has a more robust body ( Fig. 13), the sensorial areas of antennomeres III–IV are not divided by a carina, the posterior angles of the pronotum protrude almost at a right angle (Fig. 10). Parandra (P.) angulicollis Bates, 1879 is the species of the subgenus that presents the nearest geographical distribution to Parandra (P.) antioquensis new species. Differences between both species are: the punctuation of head and pronotum which is clearly finer and denser in Parandra (P.) antioquensis new species (Fig. 9), and the shape of the posterior angles of pronotum which are rounded in the new species, and at a right angle in Parandra (P.) angulicollis (Figs. 9 and 11).
