Based on differences in coloration, morphometrics, and scalation, I recognize seven species of anoles related to Anolis pentaprion in Central America: Anolis beckeri (southeastern Mexico to northern Nicaragua), A. cristifer (Pacific lowlands of Chiapas to central Guatemala), A. fungosus (Caribbean premontane zone from central Costa Rica to western Panama), A. pentaprion (Caribbean lowlands of southern Nicaragua to northwestern Colombia, also on Pacific versant in central and eastern Panama), A. salvini (Pacific premontane and lower montane zones from central Costa Rica to western Panama), A. utilensis (restricted to Isla de Utila, Honduras), and a new species (from the Pacific lowlands of Costa Rica and western Panama) described herein. The new species differs from A. pentaprion by having a red male dewlap with few large, widely spaced gorgetal scales scattered across the dewlap (pink with purple pigment between rows of gorgetals, and with regular rows of numerous small, narrowly spaced gorgetal scales in A. pentaprion). Furthermore, I resurrect the name A. beckeri Boulenger for the pentaprion-like populations of anoles distributed from southeastern Mexico to northern Nicaragua. Anolis beckeri differs from A. pentaprion most obviously in the dorsal tail scalation (a serrated caudal crest present in A. pentaprion versus no such crest in A. beckeri) and dewlap scalation (gorgetal rows with 17–25 narrowly spaced scales in A. pentaprion versus gorgetal rows with 4–10 widely spaced scales in A. beckeri). Finally, SMF 83608 is proposed as the neotype for Anolis pentaprion. I provide standardized descriptions of A. beckeri, A. pentaprion, and the new species described herein.

A new definition for the genus Moribaetis Waltz & McCafferty 1985 is given. Its type species, Moribaetis maculipennis (Flowers 1979) is redescribed based on male and female imagoes reared from larvae near the type locality in Panama. Larvae, formerly wrongly attributed to Moribaetis salvini (Eaton 1885), and a male imago, formerly wrongly attributed to Moribaetis macaferti Waltz 1985, belong to a new species Moribaetis latipennis sp. n., which is described here based on a male imago reared from larva in Panama. Both species, M. maculipennis and M. latipennis sp. n., are distinct from M. salvini, which is known as a single male imago (lectotype) from Costa Rica. All other species, formerly attributed to Moribaetis, are excluded from this genus; a new combination Caribaetis macaferti comb. n. is proposed for the species originally described as Moribaetis macaferti Waltz (in Waltz & McCafferty) 1985, and a new combination Baetis (Rhodobaetis) mimbresaurus comb. n. is proposed for the species originally described as Moribaetis mimbresaurus McCafferty 2007.

Three new species belonging to the tribe Nymphistrini of the obligate myrmeco- and termitophilous subfamily Haeteriinae (Coleoptera: Histeridae) are described from Central America: Nymphister rettenmeyeri sp. n. (Costa Rica and Panama), Trichoreninus carltoni sp. n. (Belize and Honduras) and T. neo sp. n. (Costa Rica and Panama).  Identification keys for the Central American species of both genera are prepared.  Available host records for N. rettenmeyeri confirm the symbiosis of the genus with Eciton army ants: the species has been found in colonies of E. burchelli (Westwood), E. hamatum (Fabricius) and E. mexicanum Roger.  Host records are not available for the new species of Trichoreninus as all known specimens were collected by flight intercept traps.

A revision of the Central American species of the genus Brachiacantha was undertaken to update the knowledge of the Central American species of the genus. Material of several collections was reviewed, using original descriptions and keys, and comparing with the type material. Twenty-five species of the genus Brachiacantha were found in Central American material, including nine new species: B. nubes Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. dentata Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. isthmena Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. aurantiapleura Nestor-Arriola, Solís and Toledo-Hernández, sp. nov., B. invertita Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. papiliona Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. tica Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. hexaspina González, Větrovec and Nestor-Arriola, sp. nov., and B. mimica Nestor-Arriola and Toledo-Hernández, sp. nov. Nomenclatural changes include Brachiacantha gorhami (Weise), comb. nov., B. guatemalensis (Gorham), comb. nov., and Brachiacantha duodecimguttata Leng, syn. nov. for B. lepida Mulsant. The male genitalia of the species B. fenestrata Gorhan, B. octostigma Mulsant, B. aperta Weise, and B. cachensis Gorhan are described and illustrated for the first time. New records include B. indubitabilis Crotch and B. bipartita Mulsant (Costa Rica and Guatemala), B. gorhami (Weise) (El Salvador), and B. cachensis Gorham (Panamá). A key to the species is included.

The genus Mexitrichia Mosely, 1937 (27 described species) is synonymized with Mortoniella Ulmer, 1906 (22 described species) and a revised generic description is provided for the genus. These species are placed in 4 recognized species groups. Mexican and Central American species of Mortoniella are revised to include 6 species formerly placed in Mexitrichia and 22 new species from Costa Rica, Panama, and Mexico. New species combinations for these regional species include: Mortoniella florica (Flint, 1974), M. leroda (Mosely, 1937), M. meralda (Mosely, 1954), M. pacuara (Flint, 1974), M. rancura (Mosely, 1954), and M. rovira (Flint, 1974). New species of Mortoniella described here (followed by the country of provenance) include M. akantha (Costa Rica) M. anakantha (Costa Rica) M. aviceps (Costa Rica, Panama) M. brachyrhachos (Mexico), M. buenoi (Mexico), M. carinula (Costa Rica), M. caudicula (Costa Rica), M. falcicula (Mexico), M. mexicana (Mexico) M. munozi (Costa Rica, Panama), M. opinionis (Costa Rica), M. panamensis (Panama), M. papillata (Costa Rica), M. pectinella (Panama), M. propinqua (Costa Rica), M. redunca (Costa Rica), M. rodmani (Costa Rica), M. sicula (Costa Rica), M. stilula (Costa Rica), M. tapanti (Costa Rica, Panama), M. taurina (Costa Rica, Panama), and M. umbonata (Panama).

We describe Sibon noalamina sp. nov. from the Caribbean versant of the Cordillera Central, in the Comarca Ngöbe-Bugléand the province of Veraguas of western Panama. Due to its coral snake-like, bicolored pattern, the new species superfi-cially resembles Sibon anthracops, Dipsas articulata, D. bicolor, D. temporalis, and D. viguieri. It differs from these spe-cies, and from all its congeners, by having only five supralabials, by the unique shape of the posterior supralabial, and bya slight keeling on some dorsal rows in adults. We discuss its conservation perspectives, and provide new distributional records for S. annulatus and S. longifrenis, as well as an updated key to the Lower Central American species of Sibon.

A new species of Roeboides is described from the Pacific slope of Costa Rica and Panama. Roeboides bussingi differs from all other Central American Roeboides and all members of the R. guatemalensis species group by the following combination of characters: presence of 18-22 scales above the lateral line (vs. 12-16 in R. dientito); 15-22 scales below the lateral line (vs. 10-14 in R. dientito, and 20-24 in R. loftini); an inconspicuous, sometimes absent, crescent-shaped humeral spot (vs. a large round, conspicuous humeral spot in R. carti, R. dayi, R. dientonito, R. ilseae, R. loftini,and R. occidentalis); a small wedge-shaped spot that does not reach the lateral line (vs. a large spot crossing the lateral line in R. guatemalensis); a teardrop shaped caudal spot (vs. caudal spot triangle shaped in R. bouchellei); and a dark band at the distal tip of the anal fin (vs. dark band absent in R. bouchellei). A key to all Middle American species of Roeboides is also presented
