Carinodula chiapanensis Bares and Ivie , new species

Type Specimens. Holotype ♂, allotype ♀, and seven paratypes (4 ♀♀, 3♂♂) labeled: MEXICO: Chiapas / 2km SE Custepec , 1520m / 15.72099° N, 92.95054°W / 17MAY2008; LLAMA #Wm-A-02-1/ sifted mesophyll litter. Six paratypes (2 ♀♀, 4 ♂♂) labeled: MEXICO: Chiapas / 3km SE Custepec, 1700m / 15.71604°N 92.93835°W / 17MAY2008; LLAMA # Wm-A-02-2/sifted mesophyll litter. One partial specimen from the type locality is not included in the type series. [In the LLAMA codes, “Wm” indicates Maxi-Winkler extraction; “A” indicates Mexico; the two-digit number indicates site number and the final digit the transect number (Longino and Anderson 2014).]

Holotype male and allotype female deposited in the collection of the Universidad Nacional Autónoma de México, DF, Mexico . Paratypes deposited in: Montana State University Entomology Collection , Bozeman, MT, USA ; National Museum of Natural History , Washington, DC, USA ; El Colegio de la Frontera Sur, San Cristóbal de las Casas, CH, Mexico ; Australian National Insect Collection, Canberra , Australia ; and The Natural History Museum, London , UK .

Diagnosis. Carinodula chiapanensis is characterized by the defined anterior face on the prosternum ( Fig. 4 ), truncate postcoxal lines on ventrite I ( Fig. 9 ), and the shape of the aedeagus ( Fig. 6 ) and spermathecal capsule ( Fig. 5 ). The new species has an 11-segmented antenna, lacks pronotal pits, and has four tarsomeres, placing it in Carinodula , the latter two characters separating it from the other genera of the tribe. The 11-segmented antenna is shared only with the Asian Carinodulina Ślipiński and Jadwiszczak.

Description. With the characters of the tribe and genus. Length 1.30–1.45 mm. Body about 1.84–2.00X longer than wide, widest at middle ( Figs. 1–2 ). Color yellowish brown to light brown, appendages lighter in color. Vestiture of semidecumbent, white hairs; hairs relatively long, distinctly visible at 10X magnification. Punctures on head smaller than on pronotum, separated by more than diameter of puncture; punctures on elytron slightly larger than on pronotum, separated by diameter of puncture or slightly more. Pronotum 0.37–0.44 mm long, 0.52–0.62 mm wide, about 0.68–0.72X longer than wide. Elytra 0.89–0.98 mm long, about 2.22–2.40X longer than pronotum. Pronotum with lateral edge moderately crenulate. Prosternum with defined anterior face and intercoxal process relatively narrow, widened apically, procoxal cavities widely open ( Fig. 4 ). Ventrite I with truncate postcoxal lines ( Fig. 9 ). Male with median patch of setae on ventrite I ( Fig. 9 ). Male aedeagus as in Fig. 6 , siphon (penis) as in Fig. 8 . Spermathecal capsule as in Fig. 5 .

Etymology. The species name chiapanensis is an adjective derived from the name of the home mountains of the species, the Sierra Madre de Chiapas.

Habitat and Distribution. All C. chiapanensis specimens were collected with Maxi-Winklers from sifted leaf litter at two sites located about 2–3 kilometers southeast of the small town of Custepec in the Sierra Madre de Chiapas ( Fig. 10 ). The localities are at mid-elevations (1,520 –1,700 m) in a combination of old-growth and second-growth wet evergreen mesophyll forest (Longino and Anderson 2014). Carinodula campbelli was collected in the Central Chiapas Highlands ( Fig. 10 ) north of the Valle Central, which separates the two localities.
