Stark Box 4045, Department of Biology, Mississippi College, Clinton, Mississippi, U.S.A. 39058 E-mail: stark@mc.edu ABSTRACT Three new species, Anacroneuria guanacaste, A. morsei and A. tempisquito are described based on Costa Rican specimens and an additional new species, A. totumas is described from Panamanian specimens. Anacroneuria azul Rojas & Baena and A. marca Stark are reported from Panama for the first time, and the presence of A. lineata (Navas) in Panama, is confirmed. Six additional new provincial records are presented for Costa Rica and one each for Guatemala and Panama. Keywords: Plecoptera, Perlidae, Anacroneuria, Mesoamerica, new species, new records INTRODUCTION A minimum of 40, currently accepted species of Anacroneuria have been reported for the Mesoamerican nations which lie between Mexico and Colombia (Fenoglio & Morisi 2000; Fenoglio 2007; Harper 1992; Jewett 1958; Needham & Broughton 1927; Stark 1998; Stark & Kondratieff 2004), yet much of this region remains unstudied and the fauna may be significantly more diverse than current data suggests. The only moderately comprehensive studies (Costa Rica, Stark 1998 and Mexico, Stark & Kondratieff 2004) produced 25 and 30 Anacroneuria species respectively, with only eight species common to the two areas. In the Costa Rican study many specimens came from a single location on Rio Tempisquito, Estación Biológica Maritza in Guanacaste Province, a site which produced adults of 13 Anacroneuria species over the course of four years (1987-1990) of light trapping (Stark 1998). In this study, two additional new species are recognized from this site. The current study is based on samples provided by R.W. Baumann and the Monte L. Bean Life Science Museum, Brigham Young University, and miscellaneous specimens from various sources, not included in an earlier study of the Costa Rican and Panamanian fauna (Stark 1998). These samples include one, previously unrecognized species from Panama, three from Costa Rica, the first Panamanian records of Anacroneuria azul Rojas & Baena, 1999 (Stark et al. 1999) and A. marca Stark, 1998, six new provincial records from Heredia and Cartago Province, Costa Rica and one each from Baja Verapaz Province, Guatemala, and Chiriqui Province, Panama. Table 1 presents a current list of the Anacroneuria species known for the Mesoamerican region, together with their respective distributions. MATERIALS AND METHODS Specimens were prepared for study following the procedures outlined by Stark (2013). Selected structures were drawn using Wild M5A and Olympus SZH10 stereomicroscopes equipped with drawing tubes. Holotypes are deposited in the United States National Museum of Natural History through the courtesy of the Monte L. Bean Life Science Museum and the Stroud Water Research Center.

Forewing length 12 mm. Hammer thimble shaped, height slightly greater than apical diameter (Fig. 2). Aedeagal apex simple, notched on apical margin; ventral membranous lobes conspicuous (Fig. 3). In lateral aspect, apex is somewhat foot-shaped, but with a slightly bulging process at ankle (Fig. 4). Dorsal keel consists of an obscure series of low chevron-like lines (Fig. 5), but median line absent. Hooks slender. Female. Unknown. Larva. Unknown. Etymology. The species name, based on Guanacaste Province, is used as a noun in apposition. Diagnosis. In the Stark (1998) key this species runs to couplet 18 where an impasse occurs due to the intermediate forewing length. If the impasse is resolved by choosing the greater length (13 mm), no resolution is gained, although a determination of A. marca or A. ventana Stark, 1998 can be forced; if the smaller length (10 mm) is chosen a determination of A. varilla Stark, 1998 is made. In some respects, A. guanacaste is intermediate between these species with a slender, thimble-shaped hammer like that of A. marca, and with an aedeagal apex more similar to that of A. varilla. The new species is distinguished from both by the apical notch in the aedeagal tip (Fig. 3), and by the chevron- like dorsal keel (Fig. 5). The species is probably a near relative of A. flavominuta Jewet, 1958 and other Mexican species (Stark & Kondratieff 2004. Anacroneuria holzenthali Stark Anacroneuria holzenthali Stark 1998:568.

Veraguas, Alto de Piedra, 08° 30.9' N, 81° 07.0' W, 16-18 June 2011, E. Fuller, (BYUC). Comments. Several Costa Rican provincial records of this species are given in Stark (1998) and additional records are given for Belize, Guatemala, Honduras and Mexico in Stark & Kondratieff (2004). Jewett (1958) lists a male and two female specimens from "El Volcan, Chiriqui, Panama" among the specimens he determined as A. sulana, a synonym of A. lineata (Stark & Kondratieff 2004). These records may be valid, however, to my knowledge they have not been examined since the 1950's. The specimens listed above indicate the species is a valid member of the Panamanian fauna. The specimen from Veraguas has a thimble-shaped hammer rather than nipple shaped and has other subtle features which suggest it may represent a species distinct from A. lineata.

General color yellow patterned with brown pigment. Head with dark pigment covering ocelli and extending forward and laterad of callosities; occiput dark behind eyes, lappets and an anteromedian triangular area of frons dark brown. Median pronotal band yellow, lateral areas of disc brown with darker rugosities (Fig. 6). Male. Forewing length 20 mm. Hammer a low mound (Fig. 7). Aedeagal apex weakly trilobed; large mesal lobe truncate or notched at tip, lateral lobes small and covered by conspicuous ventral membranous lobes (Figs. 8-9); hooks slender, dorsal keel absent (Fig. 10) Female. Unknown. Larva. Unknown. Etymology. The patronym honors Dr. John Morse, a distinguished trichopterist, colleague, friend, and collector of the holotype specimen. Diagnosis. The aedeagus of this species is generally similar to that of A. brailovskyi Stark & Kondratieff, 2004 a species known from Mexico (Stark & Kondratieff 2004), however in that species the aedeagal apex is expanded near the tip, the lateral lobes are less distinct and the apical section is not angled ventrad in lateral aspect as in the new species (Fig. 9). The aedeagus of a Costa Rican species, A. exquisita is also similar (Stark 1998) and the new species keys to couplet 11 in Stark (1998) which includes A. exquisita as one of the choices. However, the median lobe of the aedeagal apex is not notched and is more slender than in A. morsei. The new species is also distinct from A. brailovskyi and A. exquisita in head and pronotal pigment patterns (compare Fig. 6 with Fig. 41 in Stark 1998 and Fig. 29 in Stark & Kondratieff 2004).

Holotype $, Costa Rica, Guanacaste Province, Estación Biológica Maritza, Rio Tempisquito, 21 May 1990, light trap (USNM). Adult habitus. Head yellow except for diffuse brown area forward of ocelli and dark brown lappets and antennae (Fig. 11). Pronotum with pale mesal band; dark lateral bands cover most of disc. Wing membrane transparent with pale amber tint; veins darker except for pale costa. Femora pale except for narrow black apical band; tibiae dark in proximal fourth and with a small distal dark spot. Male. Forewing length 10 mm. Hammer reduced to a small, transparent, hairless disc (Fig. 12). Aedeagal apex pointed in ventral aspect and bearing a prominent pair of ventral, membranous lobes (Fig. 13); apex angled sharply ventrad in lateral aspect (Fig. 14), and bearing an obscure V-shaped dorsal keel composed of divergent, broken lines (Fig. 15). Hooks slender with long acute tips. Female. Unknown. Larva. Unknown. Etymology. The species name, based on Rio Tempisquito, is used as a noun in apposition. Diagnosis. This species does not appear to be closely related to others known from Mesoamerica, but is more similar to the Ecuadorian species, A. cajas Zúñiga & Vimos, 2006 (Zúñiga et al. 2006) and the Colombian species A. otun Stark & Zúñiga, 2007 (Zúñiga et al. 2007). The new species is distinguished from both on the basis of pigment pattern, the prominent ventral membranous lobes, the dorsal keel, and the obscure hammer. In Stark (1998) the new species will key to couplet 9 where a choice of A. varilla could be forced, despite conspicuous differences in aedeagal structure. Anacroneuria totumas sp. n.

Head with dark lappets, antennae and a dark band extends from behind ocelli forward to M-line; dark band expanded laterally along M-line, and interrupted by a pale interocellar spot (Fig. 16). Pronotum dark over most of disc, but with a slender pale median band. Wings pale brown, veins brown except for C and apical half of SC. Femora pale in proximal half and dark brown in distal half; fore and mid tibiae brown, hind tibiae with pale transverse median band. Male. Forewing length 20 mm. Hammer a low, mound-like structure (Fig. 17). Aedeagal apex simple (Figs. 18-19); ventroapical aspect with a large pair of membranous lobes overlying darkly sclerotized lateral margins (Fig. 18); dorsal keel absent, lateral margins slightly convergent to truncate apex (Fig. 20). Hooks slender. Female. Unknown. Larva. Unknown. Etymology. The species name, based on the type locality at the Mount Totumas Cloud Forest, is used as a noun in apposition. Diagnosis. This species keys to couplet 11 in Stark (1998) where A. acutipennis Klapalek, 1923 and A. equisita, a pair of species with trilobed aedeagal apices are the options. Because the new species has a simple aedeagal apex without lateral lobes, neither of these choices are viable. The aedeagal apex of the new species is generally similar to that of A. varilla, a much smaller species (male FWL = 9-10 mm) known from Costa Rica and Panama (Stark 1998).

Bean Life Science Museum for sending material used in this study. I also thank the Florida Collection of Arthropods, The Stroud Water Research Center, the United States National Museum of Natural History and Ralph Holzenthal, University of Minnesota, for providing material. Three of my former undergraduate students, David Bradshaw, Judd Mason and Walter Pang, made major contributions by sorting, clearing and screening unstudied male specimens from Estación Biológica Maritza light traps. Their careful work led to the discovery and description of two of the new Costa Rican species. REFERENCES Banks, N. 1914. New neuropteroid insects, native and exotic.
